Balena CLI Documentation

The balena CLI (Command-Line Interface) allows you to interact with the balenaCloud and the balena API through a terminal window on Linux, macOS or Windows. You can also write shell scripts around it, or import its Node.js modules to use it programmatically. As an open-source project on GitHub, your contribution is also welcome!

Installation

Check the balena CLI installation instructions on GitHub.

Getting Started

Choosing a shell (command prompt/terminal)

On Windows, the standard Command Prompt (cmd.exe) and PowerShell are supported. We are aware of users also having a good experience with alternative shells, including:

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 order of preference:

  • Set the BALENARC_PROXY environment variable in URL format (with protocol, host, port, and optionally basic auth).
  • Alternatively, use the balena config file (project-specific or user-level) and set the proxy setting. It can be:
  • Alternatively, set the conventional https_proxy / HTTPS_PROXY / http_proxy / HTTP_PROXY environment variable (in the same standard URL format).

To get a proxy to work with the balena ssh command, check the installation instructions.

Support, FAQ and troubleshooting

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

CLI Command Reference

API keys

api-key generate <name>

This command generates a new API key for the current user, with the given name. The key will be logged to the console.

Sync

sync [uuid]

Deprecation notice: please note that balena sync is deprecated and will be removed in a future release of the CLI. We are working on an exciting replacement that will be released soon!

Warning: 'balena sync' requires an openssh-compatible client and 'rsync' to be correctly installed in your shell environment. For more information (including Windows support) please check the README here: https://github.com/balena-io/balena-cli

Use this command to sync your local changes to a certain device on the fly.

After every 'balena sync' the updated settings will be saved in '/.balena-sync.yml' and will be used in later invocations. You can also change any option by editing '.balena-sync.yml' directly.

Here is an example '.balena-sync.yml' :

$ cat $PWD/.balena-sync.yml
uuid: 7cf02a6
destination: '/usr/src/app'
before: 'echo Hello'
after: 'echo Done'
ignore:
	- .git
	- node_modules/

Command line options have precedence over the ones saved in '.balena-sync.yml'.

If '.gitignore' is found in the source directory then all explicitly listed files will be excluded from the syncing process. You can choose to change this default behavior with the '--skip-gitignore' option.

Examples:

$ balena sync 7cf02a6 --source . --destination /usr/src/app
$ balena sync 7cf02a6 -s /home/user/myBalenaProject -d /usr/src/app --before 'echo Hello' --after 'echo Done'
$ balena sync --ignore lib/
$ balena sync --verbose false
$ balena sync

Options

--source, -s <path>

local directory path to synchronize to device

--destination, -d <path>

destination path on device

--ignore, -i <paths>

comma delimited paths to ignore when syncing

--skip-gitignore

do not parse excluded/included files from .gitignore

--skip-restart

do not restart container after syncing

--before, -b <command>

execute a command before syncing

--after, -a <command>

execute a command after syncing

--port, -t <port>

ssh port

--progress, -p

show progress

--verbose, -v

SSH

ssh <applicationOrDevice> [serviceName]

This command can be used to 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, all online devices in the application will be presented, and the chosen device will then have a shell opened on in it's service container or host OS.

For local devices, the ip address and .local domain name are supported.

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

Warning: '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

Options

--port, -p <port>

--verbose, -v

Increase verbosity

--noproxy

Don't use the proxy configuration for this connection. This flag only make sense if you've configured a proxy globally.

tunnel <uuid>

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.

You can tunnel multiple ports at any given time.

Examples:

# map remote port 22222 to localhost:22222
$ balena tunnel abcde12345 -p 22222

# map remote port 22222 to localhost:222
$ balena tunnel abcde12345 -p 22222:222

# map remote port 22222 to any address on your host machine, port 22222
$ balena tunnel abcde12345 -p 22222:0.0.0.0

# map remote port 22222 to any address on your host machine, port 222
$ balena tunnel abcde12345 -p 22222:0.0.0.0:222

# multiple port tunnels can be specified at any one time
$ balena tunnel abcde12345 -p 8080:3000 -p 8081:9000

Options

--port, -p <port>

The mapping of remote to local ports.

Notes

note <|note>

Use this command to set or update a device note.

If note command isn't passed, the tool attempts to read from stdin.

To view the notes, use $ balena device .

Examples:

$ balena note "My useful note" --device 7cf02a6
$ cat note.txt | balena note --device 7cf02a6

Options

OS

os versions <type>

Use this command to show the available balenaOS versions for a certain device type. Check available types with balena devices supported

Example:

$ balena os versions raspberrypi3

os download <type>

Use this command to download an unconfigured os image for a certain device type. Check available types with balena devices supported

If version is not specified the newest stable (non-pre-release) version of OS is downloaded if available, or the newest version otherwise (if all existing versions for the given device type are pre-release).

You can pass --version menu to pick the OS version from the interactive menu of all available versions.

Examples:

$ balena os download raspberrypi3 -o ../foo/bar/raspberry-pi.img
$ balena os download raspberrypi3 -o ../foo/bar/raspberry-pi.img --version 1.24.1
$ balena os download raspberrypi3 -o ../foo/bar/raspberry-pi.img --version ^1.20.0
$ balena os download raspberrypi3 -o ../foo/bar/raspberry-pi.img --version latest
$ balena os download raspberrypi3 -o ../foo/bar/raspberry-pi.img --version default
$ balena os download raspberrypi3 -o ../foo/bar/raspberry-pi.img --version menu

Options

--output, -o <output>

output path

--version <version>

exact version number, or a valid semver range, or 'latest' (includes pre-releases), or 'default' (excludes pre-releases if at least one stable version is available), or 'recommended' (excludes pre-releases, will fail if only pre-release versions are available), or 'menu' (will show the interactive menu)

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

Use this command to prebuild the OS config once and skip the interactive part of balena os configure.

Example:

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

Options

--advanced, -v

show advanced configuration options

--output, -o <output>

the path to the output JSON file

os configure <image>

Use this command to configure a previously downloaded operating system image for the specific device or for an application generally.

This command will try to automatically determine the operating system version in order to correctly configure the image. It may fail to do so however, in which case you'll have to call this command again with the exact version number of the targeted image.

Note that device api keys are only supported on balenaOS 2.0.3+.

This command still supports the deprecated format where the UUID and optionally device key are passed directly on the command line, but the recommended way is to pass either an --app or --device argument. The deprecated format will be removed in a future release.

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:

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

Push

push <applicationOrDevice>

This command can be used to start a build on the remote balena cloud 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.

It is also possible to run a push to a local mode device in live mode. This will watch for changes in the source directory and perform an in-place build in the running containers [BETA].

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}'

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

Options

--source, -s <source>

The source that should be sent to the balena builder to be built (defaults to the current directory)

--emulated, -e

Force an emulated build to occur on the remote builder

--dockerfile <Dockerfile>

--registry-secrets, -R <secrets.yml|.json>

Path to a local YAML or JSON file containing Docker registry passwords used to pull base images

--live, -l

Note this feature is in beta.

Start a live session with the containers pushed to a local mode device. The project source folder is watched for filesystem events, and changes to files and folders are automatically synchronized to the running containers. The synchronisation 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.

--detached, -d

Don't tail application logs when pushing to a local mode device

--service <service>

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

local ssh [deviceIp]

Warning: 'balena local ssh' requires an openssh-compatible client to be correctly installed in your shell environment. For more information (including Windows support) please check the README here: https://github.com/balena-io/balena-cli

Use this command to get a shell into the running application container of your device.

The '--host' option will get you a shell into the Host OS of the balenaOS device. No option will return a list of containers to enter or you can explicitly select one by passing its name to the --container option

Examples:

$ balena local ssh
$ balena local ssh --host
$ balena local ssh --container chaotic_water
$ balena local ssh --container chaotic_water --port 22222
$ balena local ssh --verbose

Options

--verbose, -v

increase verbosity

--host, -s

get a shell into the host OS

--container, -c <container>

name of container to access

--port, -p <port>

ssh port number (default: 22222)

local push [deviceIp]

Deprecation notice: balena local push is deprecated and will be removed in a future release of the CLI. Please use balena push <ipAddress> instead.

Use this command to push your local changes to a container on a LAN-accessible balenaOS device on the fly.

This command requires an openssh-compatible 'ssh' client and 'rsync' to be available in the executable PATH of the shell environment. For more information (including Windows support) please check the README at: https://github.com/balena-io/balena-cli

If Dockerfile or any file in the 'build-triggers' list is changed, a new container will be built and run on your device. If not, changes will simply be synced with rsync into the application container.

After every 'balena local push' the updated settings will be saved in '/.balena-sync.yml' and will be used in later invocations. You can also change any option by editing '.balena-sync.yml' directly.

Here is an example '.balena-sync.yml' :

$ cat $PWD/.balena-sync.yml
local_balenaos:
	app-name: local-app
	build-triggers:
		- Dockerfile: file-hash-abcdefabcdefabcdefabcdefabcdefabcdef
		- package.json: file-hash-abcdefabcdefabcdefabcdefabcdefabcdef
	environment:
		- MY_VARIABLE=123

Command line options have precedence over the ones saved in '.balena-sync.yml'.

If '.gitignore' is found in the source directory then all explicitly listed files will be excluded when using rsync to update the container. You can choose to change this default behavior with the '--skip-gitignore' option.

Examples:

$ balena local push
$ balena local push --app-name test-server --build-triggers package.json,requirements.txt
$ balena local push --force-build
$ balena local push --force-build --skip-logs
$ balena local push --ignore lib/
$ balena local push --verbose false
$ balena local push 192.168.2.10 --source . --destination /usr/src/app
$ balena local push 192.168.2.10 -s /home/user/balenaProject -d /usr/src/app --before 'echo Hello' --after 'echo Done'

Options

--source, -s <path>

root of project directory to push

--destination, -d <path>

destination path on device container

--ignore, -i <paths>

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 to use the balena Dockerfile pre-processor (e.g. Dockerfile.template -> Dockerfile).

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. If it is found, this command will build each service defined in the compose file. 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.

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}'

Examples:

$ balena build
$ balena build ./source/
$ balena build --deviceType raspberrypi3 --arch armv7hf --emulated
$ balena build --application MyApp ./source/
$ balena build --docker '/var/run/docker.sock'

Set a build-time variable (eg. "-B 'ARG=value'"). Can be specified multiple times.

--nocache

Don't use docker layer caching when building

--squash

Squash newly built layers into a single new layer

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>.

When --build is used, all options supported by balena build are also supported by this command.

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}'

Platform

join [deviceIp]

Use this command to move a local device to an application on another balena server.

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.

Moving a device between applications on the same server is not supported.

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 usually requires root privileges.

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

Options

--application, -a <application>

The name of the application the device should join

leave [deviceIp]

Use this command to make a local device leave the balena server it is provisioned on. This effectively makes the device "unmanaged".

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

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 usually requires root privileges.

Examples:

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

Utilities

util available-drives

Use this command to list your machine's drives usable for writing the OS image to. Skips the system drives.
