balena CLI Documentation

The balena CLI is a Command Line Interface for balenaCloud or openBalena. It is a software tool available for Windows, macOS and Linux, used through a command prompt / terminal window. It can be used interactively or invoked in scripts. The balena CLI builds on the balena API and the balena SDK, and can also be directly imported in Node.js applications. The balena CLI is an open-source project on GitHub, and your contribution is also welcome!

Installation

Check the balena CLI installation instructions on GitHub.

Choosing a shell (command prompt/terminal)

On Windows, the standard Command Prompt (cmd.exe) and PowerShell are supported. Alternative shells include:

MSYS2:
- Install additional packages with the command:
  pacman -S git openssh rsync
- Set a Windows environment variable: MSYS2_PATH_TYPE=inherit
- Note that a bug in the MSYS2 launch script (msys2_shell.cmd) makes text-based interactive CLI menus to break. Check this Github issue for a workaround.
MSYS: select the msys-rsync and msys-openssh packages too
Git for Windows
- During the installation, you will be prompted to choose between "Use MinTTY" and "Use Windows' default console window". Choose the latter, because of the same MSYS2 bug mentioned above (Git for Windows actually uses MSYS2). For a screenshot, check this comment.
Microsoft's Windows Subsystem for Linux (WSL). In this case, a Linux distribution like Ubuntu is installed via the Microsoft Store, and a balena CLI release for Linux should be selected. See FAQ for using the balena CLI with WSL and Docker Desktop for Windows.

On macOS and Linux, the standard terminal window is supported. Optionally, bash command auto completion may be enabled by copying the balena-completion.bash file to your system's bash_completion directory: check Docker's command completion guide for system setup instructions.

Logging in

Several CLI commands require access to your balenaCloud account, for example in order to push a new release to your application. Those commands require creating a CLI login session by running:

$ balena login

Proxy support

HTTP(S) proxies can be configured through any of the following methods, in precedence order (from higher to lower):

The BALENARC_PROXY environment variable in URL format, with protocol (http or https), host, port and optionally basic auth. Examples:
- export BALENARC_PROXY='https://bob:secret@proxy.company.com:12345'
- export BALENARC_PROXY='http://localhost:8000'
The proxy setting in the CLI config file. It may be:
- A string in URL format, e.g. proxy: 'http://localhost:8000'
- An object in the format:
```
proxy:
    protocol: 'http'
    host: 'proxy.company.com'
    port: 12345
    proxyAuth: 'bob:secret'
```
The HTTPS_PROXY and/or HTTP_PROXY environment variables, in the same URL format as BALENARC_PROXY.

Proxy setup for balena ssh

In order to work behind a proxy server, the balena ssh command requires the proxytunnel package (command-line tool) to be installed. proxytunnel is available for Linux distributions like Ubuntu/Debian (apt install proxytunnel), and for macOS through Homebrew. Windows support is limited to the Windows Subsystem for Linux (e.g., by installing Ubuntu through the Microsoft App Store).

Ensure that the proxy server is configured to allow proxy requests to ssh port 22, using SSL encryption. For example, in the case of the Squid proxy server, it should be configured with the following rules in the squid.conf file:
acl SSL_ports port 22
acl Safe_ports port 22

Proxy exclusion

The BALENARC_NO_PROXY variable may be used to exclude specified destinations from proxying.

This feature requires CLI version 11.30.8 or later. In the case of the npm installation option, it also requires Node.js version 10.16.0 or later.

To exclude a balena ssh target from proxying (IP address or .local hostname), the --noproxy option should be specified in addition to the BALENARC_NO_PROXY variable.

By default (if BALENARC_NO_PROXY is not defined), all private IPv4 addresses and '*.local' hostnames are excluded from proxying. Other hostnames that resolve to private IPv4 addresses are not excluded by default, because matching takes place before name resolution.

localhost and 127.0.0.1 are always excluded from proxying, regardless of the value of BALENARC_NO_PROXY.

The format of the BALENARC_NO_PROXY environment variable is a comma-separated list of patterns that are matched against hostnames or IP addresses. For example:

export BALENARC_NO_PROXY='*.local,dev*.mycompany.com,192.168.*'

Matched patterns are excluded from proxying. Wildcard expressions are documented at matcher. Matching takes place before name resolution, so a pattern like '192.168.*' will not match a hostname that resolves to an IP address like 192.168.1.2.

Support, FAQ and troubleshooting

If you come across any problems or would like to get in touch:

Check our FAQ / troubleshooting document.
Ask us a question through the balenaCloud forum.
For bug reports or feature requests, have a look at the GitHub issues or create a new one.

Deprecation policy

The balena CLI uses semver versioning, with the concepts of major, minor and patch version releases.

The latest release of a major version of the balena CLI will remain compatible with the balenaCloud backend services for at least one year from the date when the following major version is released. For example, balena CLI v10.17.5, as the latest v10 release, would remain compatible with the balenaCloud backend for one year from the date when v11.0.0 is released.

At the end of this period, the older major version is considered deprecated and some of the functionality that depends on balenaCloud services may stop working at any time. Users are encouraged to regularly update the balena CLI to the latest version.

Device

devices

list all devices that belong to you.

You can filter the devices by application by using the --application option.

The --json option is recommended when scripting the output of this command, because field names are less likely to change in JSON format and because it better represents data types like arrays, empty strings and null values. The 'jq' utility may be helpful for querying JSON fields in shell scripts (https://stedolan.github.io/jq/manual/).

Examples:

$ balena devices
$ balena devices --application MyApp
$ balena devices --app MyApp
$ balena devices -a MyApp

Options

-a, --application APPLICATION

application name

--app APP

same as '--application'

-j, --json

produce JSON output instead of tabular output

devices supported

List the supported device types (like 'raspberrypi3' or 'intel-nuc').

The --verbose option adds extra columns/fields to the output, including the "STATE" column whose values are one of 'new', 'released' or 'discontinued'. However, 'discontinued' device types are only listed if the '--discontinued' option is used.

The --json option is recommended when scripting the output of this command, because the JSON format is less likely to change and it better represents data types like lists and empty strings (for example, the ALIASES column contains a list of zero or more values). The 'jq' utility may be helpful in shell scripts (https://stedolan.github.io/jq/manual/).

Examples:

$ balena devices supported
$ balena devices supported --verbose
$ balena devices supported -vj

Options

--discontinued

include "discontinued" device types

-j, --json

produce JSON output instead of tabular output

-v, --verbose

add extra columns in the tabular output (ALIASES, ARCH, STATE)

-d, --drive DRIVE

the drive to write the image to, eg. /dev/sdb or /dev/mmcblk0. Careful with this as you can erase your hard drive. Check balena util available-drives for available options.

--config CONFIG

path to the config JSON file, see balena os build-config

device move <uuid(s)>

Move one or more devices to another application.

Note, if the application option is omitted it will be prompted for interactively.

Environment Variables

envs

List the environment or configuration variables of an application, device or service, as selected by the respective command-line options. (A service is an application container in a "microservices" application.)

The results include application-wide (fleet), device-wide (multiple services on a device) and service-specific variables that apply to the selected application, device or service. It can be thought of as including "inherited" variables; for example, a service inherits device-wide variables, and a device inherits application-wide variables.

The printed output may include DEVICE and/or SERVICE columns to distinguish between application-wide, device-specific and service-specific variables. An asterisk in these columns indicates that the variable applies to "all devices" or "all services".

The --config option is used to list "configuration variables" that control balena platform features, as opposed to custom environment variables defined by the user. The --config and the --service options are mutually exclusive because configuration variables cannot be set for specific services.

The --json option is recommended when scripting the output of this command, because the JSON format is less likely to change and it better represents data types like lists and empty strings. The 'jq' utility may be helpful in shell scripts (https://stedolan.github.io/jq/manual/). When --json is used, an empty JSON array ([]) is printed instead of an error message when no variables exist for the given query. When querying variables for a device, note that the application name may be null in JSON output (or 'N/A' in tabular output) if the application linked to the device is no longer accessible by the current user (for example, in case the current user has been removed from the application by its owner).

Examples:

$ balena envs --application MyApp
$ balena envs --application MyApp --json
$ balena envs --application MyApp --service MyService
$ balena envs --application MyApp --service MyService
$ balena envs --application MyApp --config
$ balena envs --device 7cf02a6
$ balena envs --device 7cf02a6 --json
$ balena envs --device 7cf02a6 --config --json
$ balena envs --device 7cf02a6 --service MyService

Options

--all

No-op since balena CLI v12.0.0.

-a, --application APPLICATION

application name

-c, --config

show configuration variables only

-d, --device DEVICE

device UUID

-j, --json

produce JSON output instead of tabular output

-v, --verbose

produce verbose output

-s, --service SERVICE

service name

env rm <id>

Remove a configuration or environment variable from an application, device or service, as selected by command-line options.

Variables are selected by their database ID (as reported by the 'balena envs' command) and one of six database "resource types":

application (fleet) environment variable
application (fleet) configuration variable (--config)
application (fleet) service variable (--service)
device environment variable (--device)
device configuration variable (--device --config)
device service variable (--device --service)

The --device option selects a device-specific variable instead of an application (fleet) variable.

The --config option selects a configuration variable. Configuration variable names typically start with the 'BALENA_' or 'RESIN_' prefixes and are used to configure balena platform features.

The --service option selects a service variable, which is an environment variable that applies to a specifc service (application container) in a microservices (multicontainer) application.

The --service and --config options cannot be used together, but they can be used alongside the --device option to select a device-specific service or configuration variable.

Interactive confirmation is normally asked before the variable is deleted. The --yes option disables this behavior.

Examples:

$ balena env rm 123123
$ balena env rm 234234 --yes
$ balena env rm 345345 --config
$ balena env rm 456456 --service
$ balena env rm 567567 --device
$ balena env rm 678678 --device --config
$ balena env rm 789789 --device --service --yes

Arguments

ID

variable's numeric database ID

Options

-c, --config

select a configuration variable (may be used together with the --device option)

-d, --device

select a device-specific variable instead of an application (fleet) variable

-s, --service

select a service variable (may be used together with the --device option)

-y, --yes

do not prompt for confirmation before deleting the variable

env add <name> [value]

Add an environment or config variable to one or more applications, devices or services, as selected by the respective command-line options. Either the --application or the --device option must be provided, and either may be be used alongside the --service option to define a service-specific variable. (A service is an application container in a "microservices" application.) When the --service option is used in conjunction with the --device option, the service variable applies to the selected device only. Otherwise, it applies to all devices of the selected application (i.e., the application's fleet). If the --service option is omitted, the variable applies to all services.

If VALUE is omitted, the CLI will attempt to use the value of the environment variable of same name in the CLI process' environment. In this case, a warning message will be printed. Use --quiet to suppress it.

'BALENA_' or 'RESIN_' are reserved variable name prefixes used to identify "configuration variables". Configuration variables control balena platform features and are treated specially by balenaOS and the balena supervisor running on devices. They are also stored differently in the balenaCloud API database. Configuration variables cannot be set for specific services, therefore the --service option cannot be used when the variable name starts with a reserved prefix. When defining custom application variables, please avoid the reserved prefixes.

Examples:

$ balena env add TERM --application MyApp
$ balena env add EDITOR vim --application MyApp
$ balena env add EDITOR vim --application MyApp,MyApp2
$ balena env add EDITOR vim --application MyApp --service MyService
$ balena env add EDITOR vim --application MyApp,MyApp2 --service MyService,MyService2
$ balena env add EDITOR vim --device 7cf02a6
$ balena env add EDITOR vim --device 7cf02a6,d6f1433
$ balena env add EDITOR vim --device 7cf02a6 --service MyService
$ balena env add EDITOR vim --device 7cf02a6,d6f1433 --service MyService,MyService2

Arguments

NAME

environment or config variable name

VALUE

variable value; if omitted, use value from this process' environment

Options

-a, --application APPLICATION

application name

-d, --device DEVICE

device UUID

-q, --quiet

suppress warning messages

-s, --service SERVICE

service name

env rename <id> <value>

Change the value of a configuration or environment variable for an application, device or service, as selected by command-line options.

Variables are selected by their database ID (as reported by the 'balena envs' command) and one of six database "resource types":

application (fleet) environment variable
application (fleet) configuration variable (--config)
application (fleet) service variable (--service)
device environment variable (--device)
device configuration variable (--device --config)
device service variable (--device --service)

The --device option selects a device-specific variable instead of an application (fleet) variable.

The --config option selects a configuration variable. Configuration variable names typically start with the 'BALENA_' or 'RESIN_' prefixes and are used to configure balena platform features.

The --service option selects a service variable, which is an environment variable that applies to a specifc service (application container) in a microservices (multicontainer) application.

The --service and --config options cannot be used together, but they can be used alongside the --device option to select a device-specific service or configuration variable.

Examples:

$ balena env rename 123123 emacs
$ balena env rename 234234 emacs --service
$ balena env rename 345345 emacs --device
$ balena env rename 456456 emacs --device --service
$ balena env rename 567567 1 --config
$ balena env rename 678678 1 --device --config

Arguments

ID

variable's numeric database ID

VALUE

variable value; if omitted, use value from this process' environment

Options

-c, --config

select a configuration variable (may be used together with the --device option)

-d, --device

select a device-specific variable instead of an application (fleet) variable

-s, --service

select a service variable (may be used together with the --device option)

This command can also be invoked with 'balena --version' or 'balena -v'.

Examples:

$ balena version
$ balena version -a
$ balena version -j
$ balena --version
$ balena -v

Options

-a, --all

include version information for additional components (Node.js)

-j, --json

Keys

keys

List all SSH keys registered in balenaCloud for the logged in user.

Examples:

$ balena keys

Options

key <id>

Display a single SSH key registered in balenaCloud for the logged in user.

Examples:

$ balena key 17

Arguments

ID

balenaCloud ID for the SSH key

Options

key add <name> [path]

Add an SSH key to the balenaCloud account of the logged in user.

If path is omitted, the command will attempt to read the SSH key from stdin.

About SSH keys
An "SSH key" actually consists of a public/private key pair. A typical name for the private key file is "id_rsa", and a typical name for the public key file is "id_rsa.pub". Both key files are saved to your computer (with the private key optionally protected by a password), but only the public key is saved to your balena account. This means that if you change computers or otherwise lose the private key, you cannot recover the private key through your balena account. You can however add new keys, and delete the old ones.

To generate a new SSH key pair, a nice guide can be found in GitHub's docs: https://help.github.com/en/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent Skip the step about adding the key to a GitHub account, and instead add it to your balena account.

Examples:

$ balena key add Main ~/.ssh/id_rsa.pub
$ cat ~/.ssh/id_rsa.pub | balena key add Main
# Windows 10 (cmd.exe prompt) example
$ balena key add Main %userprofile%.sshid_rsa.pub

Arguments

NAME

the SSH key name

PATH

the path to the public key file

Options

key rm <id>

Remove a single SSH key registered in balenaCloud for the logged in user.

The --yes option may be used to avoid interactive confirmation.

Examples:

$ balena key rm 17
$ balena key rm 17 --yes

Arguments

ID

balenaCloud ID for the SSH key

Options

-y, --yes

answer "yes" to all questions (non interactive use)

Logs

logs <device>

Show logs for a specific device.

By default, the command prints all log messages and exits.

To continuously stream output, and see new logs in real time, use the --tail option.

If an IP or .local address is passed to this command, logs are displayed from a local mode device with that address. Note that --tail is implied when this command is provided a local mode device.

Logs from a single service can be displayed with the --service flag. Just system logs can be shown with the --system flag. Note that these flags can be used together.

Note: --service and --system flags must come after the device parameter, as per examples.

Examples:

$ balena logs 23c73a1
$ balena logs 23c73a1 --tail

$ balena logs 192.168.0.31
$ balena logs 192.168.0.31 --service my-service
$ balena logs 192.168.0.31 --service my-service-1 --service my-service-2

$ balena logs 23c73a1.local --system
$ balena logs 23c73a1.local --system --service my-service

Arguments

DEVICE

device UUID, IP, or .local address

Options

-t, --tail

continuously stream output

-s, --service SERVICE

Reject logs not originating from this service. This can be used in combination with --system or other --service flags.

-S, --system

Only show system logs. This can be used in combination with --service.

Network

scan

Scan for balenaOS devices on your local network.

Examples:

$ balena scan
$ balena scan --timeout 120
$ balena scan --verbose

Options

-v, --verbose

display full info

-t, --timeout TIMEOUT

ssh <applicationOrDevice> [service]

Start a shell on a local or remote device. If a service name is not provided, a shell will be opened on the host OS.

If an application name is provided, an interactive menu will be presented for the selection of an online device. A shell will then be opened for the host OS or service container of the chosen device.

For local devices, the IP address and .local domain name are supported. If the device is referenced by IP or .local address, the connection is initiated directly to balenaOS on port 22222 via an openssh-compatible client. Otherwise, any connection initiated remotely traverses the balenaCloud VPN.

Commands may be piped to the standard input for remote execution (see examples). Note however that remote command execution on service containers (as opposed to the host OS) is not currently possible when a device UUID is used (instead of an IP address) because of a balenaCloud backend limitation.

Note: balena ssh requires an openssh-compatible client to be correctly installed in your shell environment. For more information (including Windows support) please check: https://github.com/balena-io/balena-cli/blob/master/INSTALL.md#additional-dependencies,

Examples:

$ balena ssh MyApp
$ balena ssh f49cefd
$ balena ssh f49cefd my-service
$ balena ssh f49cefd --port <port>
$ balena ssh 192.168.0.1 --verbose
$ balena ssh f49cefd.local my-service
$ echo "uptime; exit;" | balena ssh f49cefd
$ echo "uptime; exit;" | balena ssh 192.168.0.1 myService

Arguments

APPLICATIONORDEVICE

application name, device uuid, or address of local device

SERVICE

service name, if connecting to a container

Options

-p, --port PORT

SSH server port number (default 22222) if the target is an IP address or .local hostname. Otherwise, port number for the balenaCloud gateway (default 22).

-t, --tty

Force pseudo-terminal allocation (bypass TTY autodetection for stdin)

-v, --verbose

Increase verbosity

--noproxy

Bypass global proxy configuration for the ssh connection

tunnel <deviceOrApplication>

Use this command to open local ports which tunnel to listening ports on your balenaOS device.

For example, you could open port 8080 on your local machine to connect to your managed balenaOS device running a web server listening on port 3000.

Port mappings are specified in the format: [:[localIP:]localPort] localIP defaults to 'localhost', and localPort defaults to the specified remotePort value.

You can tunnel multiple ports at any given time.

Note: Port mappings must come after the deviceOrApplication parameter, as per examples.

Examples:

# map remote port 22222 to localhost:22222
$ balena tunnel myApp -p 22222

# map remote port 22222 to localhost:222
$ balena tunnel 2ead211 -p 22222:222

# map remote port 22222 to any address on your host machine, port 22222
$ balena tunnel 1546690 -p 22222:0.0.0.0

# map remote port 22222 to any address on your host machine, port 222
$ balena tunnel myApp -p 22222:0.0.0.0:222

# multiple port tunnels can be specified at any one time
$ balena tunnel myApp -p 8080:3000 -p 8081:9000

Arguments

--version VERSION

os build-config <image> <device-type>

Interactively generate an OS config once, so that the generated config file can be used in balena os configure, skipping the interactive part.

Examples:

$ balena os build-config ../path/rpi3.img raspberrypi3 --output rpi3-config.json
$ balena os configure ../path/rpi3.img --device 7cf02a6 --config rpi3-config.json

Configure a previously downloaded balenaOS image for a specific device type or balena application.

Configuration settings such as WiFi authentication will be taken from the following sources, in precedence order:

Command-line options like --config-wifi-ssid
A given config.json file specified with the --config option.
User input through interactive prompts (text menus).

The --device-type option may be used to override the application's default device type, in case of an application with mixed device types.

The --system-connection (-c) option can be used to inject NetworkManager connection profiles for additional network interfaces, such as cellular/GSM or additional WiFi or ethernet connections. This option may be passed multiple times in case there are multiple files to inject. See connection profile examples and reference at: https://www.balena.io/docs/reference/OS/network/2.x/ https://developer.gnome.org/NetworkManager/stable/nm-settings.html

The --device-api-key option is deprecated and will be removed in a future release. A suitable key is automatically generated or fetched if this option is omitted.

Note: This command is currently not supported on Windows natively. Windows users are advised to install the Windows Subsystem for Linux (WSL) with Ubuntu, and use the Linux release of the balena CLI: https://docs.microsoft.com/en-us/windows/wsl/about

Examples:

$ balena os configure ../path/rpi3.img --device 7cf02a6
$ balena os configure ../path/rpi3.img --device 7cf02a6 --device-api-key <existingDeviceKey>

Config

config generate

Generate a config.json file for a device or application.

Calling this command with the exact version number of the targeted image is required.

This command is interactive by default, but you can do this automatically without interactivity by specifying an option for each question on the command line, if you know the questions that will be asked for the relevant device type.

In case that you want to configure an image for an application with mixed device types, you can pass the --device-type argument along with --app to specify the target device type.

Examples:

Preload

preload <image>

Preload a balena application release (app images/containers), and optionally a balenaOS splash screen, in a previously downloaded '.img' balenaOS image file in the local disk (a zip file is only accepted for the Intel Edison device type). After preloading, the balenaOS image file can be flashed to a device's SD card. When the device boots, it will not need to download the application, as it was preloaded.

Warning: "balena preload" requires Docker to be correctly installed in your shell environment. For more information (including Windows support) check: https://github.com/balena-io/balena-cli/blob/master/INSTALL.md

Examples:

$ balena preload balena.img --app 1234 --commit e1f2592fc6ee949e68756d4f4a48e49bff8d72a0 --splash-image image.png
$ balena preload balena.img

Push

push <applicationOrDevice>

Start a build on the remote balenaCloud builders, or a local mode balena device.

When building on the balenaCloud servers, the given source directory will be sent to the remote server. This can be used as a drop-in replacement for the "git push" deployment method.

When building on a local mode device, the given source directory will be built on the device, and the resulting containers will be run on the device. Logs will be streamed back from the device as part of the same invocation. The web dashboard can be used to switch a device to local mode: https://www.balena.io/docs/learn/develop/local-mode/ Note that local mode requires a supervisor version of at least v7.21.0. The logs from only a single service can be shown with the --service flag, and showing only the system logs can be achieved with --system. Note that these flags can be used together.

When pushing to a local device a live session will be started. The project source folder is watched for filesystem events, and changes to files and folders are automatically synchronized to the running containers. The synchronization is only in one direction, from this machine to the device, and changes made on the device itself may be overwritten. This feature requires a device running supervisor version v9.7.0 or greater.

REGISTRY SECRETS
The --registry-secrets option specifies a JSON or YAML file containing private Docker registry usernames and passwords to be used when pulling base images. Sample registry-secrets YAML file:

	'my-registry-server.com:25000':
		username: ann
		password: hunter2
	'':  # Use the empty string to refer to the Docker Hub
		username: mike
		password: cze14
	'eu.gcr.io':  # Google Container Registry
		username: '_json_key'
		password: '{escaped contents of the GCR keyfile.json file}'

For a sample project using registry secrets with the Google Container Registry, check: https://github.com/balena-io-examples/sample-gcr-registry-secrets

If the --registry-secrets option is not specified, and a secrets.yml or secrets.json file exists in the balena directory (usually $HOME/.balena), this file will be used instead.

DOCKERIGNORE AND GITIGNORE FILES
By default, the balena CLI will use a single ".dockerignore" file (if any) at the project root (--source directory) in order to decide which source files to exclude from the "build context" (tar stream) sent to balenaCloud, Docker daemon or balenaEngine. In a microservices (multicontainer) application, the source directory is the directory that contains the "docker-compose.yml" file.

The --multi-dockerignore (-m) option may be used with microservices (multicontainer) applications that define a docker-compose.yml file. When this option is used, each service subdirectory (defined by the build or build.context service properties in the docker-compose.yml file) is filtered separately according to a .dockerignore file defined in the service subdirectory. If no .dockerignore file exists in a service subdirectory, then only the default .dockerignore patterns (see below) apply for that service subdirectory.

When the --multi-dockerignore (-m) option is used, the .dockerignore file (if any) defined at the overall project root will be used to filter files and subdirectories other than service subdirectories. It will not have any effect on service subdirectories, whether or not a service subdirectory defines its own .dockerignore file. Multiple .dockerignore files are not merged or added together, and cannot override or extend other files. This behavior maximises compatibility with the standard docker-compose tool, while still allowing a root .dockerignore file (at the overall project root) to filter files and folders that are outside service subdirectories.

balena CLI releases older than v12.0.0 also took .gitignore files into account. This behavior is deprecated, but may still be enabled with the --gitignore (-g) option if compatibility is required. This option is mutually exclusive with --multi-dockerignore (-m) and will be removed in the CLI's next major version release (v13).

Default .dockerignore patterns
When --gitignore (-g) is NOT used (i.e. when not in v11 compatibility mode), a few default/hardcoded dockerignore patterns are "merged" (in memory) with the patterns found in the applicable .dockerignore files, in the following order:

    **/.git
    < user's patterns from the applicable '.dockerignore' file, if any >
    !**/.balena
    !**/.resin
    !**/Dockerfile
    !**/Dockerfile.*
    !**/docker-compose.yml

These patterns always apply, whether or not .dockerignore files exist in the project. If necessary, the effect of the **/.git pattern may be modified by adding counter patterns to the applicable .dockerignore file(s), for example !mysubmodule/.git. For documentation on pattern format, see:

Note: the --service and --env flags must come after the applicationOrDevice parameter, as per examples.

Examples:

$ balena push myApp
$ balena push myApp --source <source directory>
$ balena push myApp -s <source directory>

$ balena push 10.0.0.1
$ balena push 10.0.0.1 --source <source directory>
$ balena push 10.0.0.1 --service my-service
$ balena push 10.0.0.1 --env MY_ENV_VAR=value --env my-service:SERVICE_VAR=value
$ balena push 10.0.0.1 --nolive

$ balena push 23c73a1.local --system
$ balena push 23c73a1.local --system --service my-service

Arguments

APPLICATIONORDEVICE

application name, or device address (for local pushes)

Options

-s, --source SOURCE

Source directory to be sent to balenaCloud or balenaOS device (default: current working dir)

-e, --emulated

Don't use native ARM servers; force QEMU ARM emulation on Intel x86-64 servers during the image build (balenaCloud).

--dockerfile DOCKERFILE

Alternative Dockerfile name/path, relative to the source folder

-c, --nocache

Don't use cached layers of previously built images for this project. This ensures that the latest base image and packages are pulled. Note that build logs may still display the message _"Pulling previous images for caching purposes" (as the cloud builder needs previous images to compute delta updates), but the logs will not display the "Using cache" lines for each build step of a Dockerfile.

--pull

When pushing to a local device, force the base images to be pulled again. Currently this option is ignored when pushing to the balenaCloud builders.

--noparent-check

Disable project validation check of 'docker-compose.yml' file in parent folder

-R, --registry-secrets REGISTRY-SECRETS

Path to a local YAML or JSON file containing Docker registry passwords used to pull base images. Note that if registry-secrets are not provided on the command line, a secrets configuration file from the balena directory will be used (usually $HOME/.balena/secrets.yml|.json)

--nolive

Don't run a live session on this push. The filesystem will not be monitored, and changes will not be synchronized to any running containers. Note that both this flag and --detached and required to cause the process to end once the initial build has completed.

-d, --detached

When pushing to the cloud, this option will cause the build to start, then return execution back to the shell, with the status and release ID (if applicable). When pushing to a local mode device, this option will cause the command to not tail application logs when the build has completed.

--service SERVICE

Reject logs not originating from this service. This can be used in combination with --system and other --service flags. Only valid when pushing to a local mode device.

--system

Only show system logs. This can be used in combination with --service. Only valid when pushing to a local mode device.

--env ENV

When performing a push to device, run the built containers with environment variables provided with this argument. Environment variables can be applied to individual services by adding their service name before the argument, separated by a colon, e.g: --env main:MY_ENV=value Note that if the service name cannot be found in the composition, the entire left hand side of the = character will be treated as the variable name.

-l, --convert-eol

No-op and deprecated since balena CLI v12.0.0

--noconvert-eol

Don't convert line endings from CRLF (Windows format) to LF (Unix format).

-m, --multi-dockerignore

Have each service use its own .dockerignore file. See "balena help push".

-G, --nogitignore

No-op (default behavior) since balena CLI v12.0.0. See "balena help push".

-g, --gitignore

Consider .gitignore files in addition to the .dockerignore file. This reverts to the CLI v11 behavior/implementation (deprecated) if compatibility is required until your project can be adapted.

Deploy

build [source]

Use this command to build an image or a complete multicontainer project with the provided docker daemon in your development machine or balena device. (See also the balena push command for the option of building images in the balenaCloud build servers.)

You must provide either an application or a device-type/architecture pair.

This command will look into the given source directory (or the current working directory if one isn't specified) for a docker-compose.yml file, and if found, each service defined in the compose file will be built. If a compose file isn't found, it will look for a Dockerfile[.template] file (or alternative Dockerfile specified with the --dockerfile option), and if no dockerfile is found, it will try to generate one.

	'my-registry-server.com:25000':
		username: ann
		password: hunter2
	'':  # Use the empty string to refer to the Docker Hub
		username: mike
		password: cze14
	'eu.gcr.io':  # Google Container Registry
		username: '_json_key'
		password: '{escaped contents of the GCR keyfile.json file}'

For a sample project using registry secrets with the Google Container Registry, check: https://github.com/balena-io-examples/sample-gcr-registry-secrets

If the --registry-secrets option is not specified, and a secrets.yml or secrets.json file exists in the balena directory (usually $HOME/.balena), this file will be used instead.

deploy <appName> [image]

Usage: deploy <appName> ([image] | --build [--source build-dir])

Use this command to deploy an image or a complete multicontainer project to an application, optionally building it first. The source images are searched for (and optionally built) using the docker daemon in your development machine or balena device. (See also the balena push command for the option of building the image in the balenaCloud build servers.)

Unless an image is specified, this command will look into the current directory (or the one specified by --source) for a docker-compose.yml file. If one is found, this command will deploy each service defined in the compose file, building it first if an image for it doesn't exist. If a compose file isn't found, the command will look for a Dockerfile[.template] file (or alternative Dockerfile specified with the -f option), and if yet that isn't found, it will try to generate one.

To deploy to an app on which you're a collaborator, use balena deploy <appOwnerUsername>/<appName>.

	'my-registry-server.com:25000':
		username: ann
		password: hunter2
	'':  # Use the empty string to refer to the Docker Hub
		username: mike
		password: cze14
	'eu.gcr.io':  # Google Container Registry
		username: '_json_key'
		password: '{escaped contents of the GCR keyfile.json file}'

For a sample project using registry secrets with the Google Container Registry, check: https://github.com/balena-io-examples/sample-gcr-registry-secrets

If the --registry-secrets option is not specified, and a secrets.yml or secrets.json file exists in the balena directory (usually $HOME/.balena), this file will be used instead.

Platform

join [deviceIpOrHostname]

Move a local device to an application on another balena server, causing the device to "join" the new server. The device must be running balenaOS.

For example, you could provision a device against an openBalena installation where you perform end-to-end tests and then move it to balenaCloud when it's ready for production.

To move a device between applications on the same server, use the balena device move command instead of balena join.

If you don't specify a device hostname or IP, this command will automatically scan the local network for balenaOS devices and prompt you to select one from an interactive picker. This requires root privileges. Likewise, if the application flag is not provided then a picker will be shown.

Examples:

$ balena join
$ balena join balena.local
$ balena join balena.local --application MyApp
$ balena join 192.168.1.25
$ balena join 192.168.1.25 --application MyApp

Arguments

DEVICEIPORHOSTNAME

the IP or hostname of device

Options

-a, --application APPLICATION

application name

-i, --pollInterval POLLINTERVAL

the interval in minutes to check for updates

leave [deviceIpOrHostname]

Remove a local device from its balena application, causing the device to "leave" the server it is provisioned on. This effectively makes the device "unmanaged". The device must be running balenaOS.

The device entry on the server is preserved after running this command, so the device can subsequently re-join the server if needed.

Examples:

$ balena leave
$ balena leave balena.local
$ balena leave 192.168.1.25

Arguments

DEVICEIPORHOSTNAME

the device IP or hostname

Options

Utilities

util available-drives

List available drives which are usable for writing an OS image to. Does not list system drives.

Options

Support

support <action>

Grant or revoke balena support agent access to devices and applications on balenaCloud. (This command does not apply to openBalena.) Access will be automatically revoked once the specified duration has elapsed.

Duration defaults to 24h, but can be specified using --duration flag in days or hours, e.g. '12h', '2d'.

Both --device and --application flags accept multiple values, specified as a comma-separated list (with no spaces).

Examples:

balena support enable --device ab346f,cd457a --duration 3d
balena support enable --application app3 --duration 12h
balena support disable -a myApp
