# Balena CLI Documentation

This tool allows you to interact with the balena api from the comfort of your command line.

Please make sure your system meets the requirements as specified in the [README](https://github.com/balena-io/balena-cli).

## Install the CLI

### Npm install

The best supported way to install the CLI is from npm:

	$ npm install balena-cli -g --production --unsafe-perm

`--unsafe-perm` is only required on systems where the global install directory is not user-writable.
This allows npm install steps to download and save prebuilt native binaries. You may be able to omit it,
especially if you're using a user-managed node install such as [nvm](https://github.com/creationix/nvm).

### Standalone install

Alternatively, if you don't have a node or pre-gyp environment, you can still install the CLI as a standalone
binary. **This is in experimental and may not work perfectly yet in all environments**, but works well in
initial cross-platform testing, so it may be useful, and we'd love your feedback if you hit any issues.

To install the CLI as a standalone binary:

* Download the latest zip for your OS from https://github.com/balena-io/balena-cli/releases.
* Extract the contents, putting the `balena-cli` folder somewhere appropriate for your system (e.g. `C:/balena-cli`, `/usr/local/lib/balena-cli`, etc).
* Add the `balena-cli` folder to your `PATH`. (
[Windows instructions](https://www.computerhope.com/issues/ch000549.htm),
[Linux instructions](https://stackoverflow.com/questions/14637979/how-to-permanently-set-path-on-linux-unix),
[OSX instructions](https://stackoverflow.com/questions/22465332/setting-path-environment-variable-in-osx-permanently))
* Running `balena` in a fresh command line should print the balena CLI help.

To update in future, simply download a new release and replace the extracted folder.

Have any problems, or see any unexpected behaviour? Please file an issue!

## Getting started

Once you have the CLI installed, you'll need to log in, so it can access everything in your balena account.

To authenticate yourself, run:

	$ balena login

You now have access to all the commands referenced below.

## Proxy support

The CLI does support HTTP(S) proxies.

You can configure the proxy using several methods (in order of their precedence):

* set the `BALENARC_PROXY` environment variable in the URL format (with protocol, host, port, and optionally the basic auth),
* use the [balena config file](https://www.npmjs.com/package/balena-settings-client#documentation) (project-specific or user-level)
and set the `proxy` setting. This can be:
	* a string in the URL format,
	* or an object following [this format](https://www.npmjs.com/package/global-tunnel-ng#options), which allows more control,
* or set the conventional `https_proxy` / `HTTPS_PROXY` / `http_proxy` / `HTTP_PROXY`
environment variable (in the same standard URL format).

# Environment Variables

## envs

Use this command to list all environment variables for
a particular application or device.

This command lists all application/device environment variables.

If you want to see config variables, used to configure
balena features, use the --config option.

At the moment the CLI does not support per-service variables,
so the following commands will only show service-wide
environment variables.

Example:

	$ balena envs --application MyApp
	$ balena envs --application MyApp --config
	$ balena envs --device 7cf02a6

### Options

#### --device, -d

device

## env add &#60;key&#62; [value]

Use this command to add an enviroment or config variable to an application.

At the moment the CLI doesn't fully support multi-container applications,
so the following commands will set service-wide environment variables.

If value is omitted, the tool will attempt to use the variable's value
as defined in your host machine.

Use the `--device` option if you want to assign the environment variable
to a specific device.

If the value is grabbed from the environment, a warning message will be printed.
Use `--quiet` to remove it.

Examples:

	$ balena env add EDITOR vim --application MyApp
	$ balena env add TERM --application MyApp
	$ balena env add EDITOR vim --device 7cf02a6

### Options

#### --application, -a, --app &#60;application&#62;

Use this command to set a tag to an application, device or release.

You can optionally provide a value to be associated with the created
tag, as an extra argument after the tag key. When the value isn't
provided, a tag with an empty value is created.

Examples:

	$ balena tag set mySimpleTag --application MyApp
	$ balena tag set myCompositeTag myTagValue --application MyApp
	$ balena tag set myCompositeTag myTagValue --device 7cf02a6
	$ balena tag set myCompositeTag myTagValue --release 1234

# Sync

## sync [uuid]

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
'<source>/.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 &#60;path&#62;

local directory path to synchronize to device

#### --destination, -d &#60;path&#62;

destination path on device

#### --ignore, -i &#60;paths&#62;

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 &#60;command&#62;

execute a command before syncing

#### --after, -a &#60;command&#62;

execute a command after syncing

#### --port, -t &#60;port&#62;

ssh port

#### --progress, -p

show progress

#### --verbose, -v

increase verbosity

# SSH

## ssh [uuid]

Warning: 'balena 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.

Examples:

	$ balena ssh MyApp
	$ balena ssh 7cf02a6
	$ balena ssh 7cf02a6 --port 8080
	$ balena ssh 7cf02a6 -v
	$ balena ssh 7cf02a6 -s

### Options

#### --port, -p &#60;port&#62;

ssh gateway port

#### --verbose, -v

increase verbosity

#### --host, -s

access host OS (for devices with balenaOS >= 2.7.5)

#### --noproxy

don't use the proxy configuration for this connection. Only makes sense if you've configured proxy globally.

# Notes

## note &#60;|note&#62;

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 <uuid>.

Examples:

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

### Options

#### --device, -d, --dev &#60;device&#62;

device uuid

# OS

## os versions &#60;type&#62;

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 &#60;type&#62;

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 &#60;output&#62;

output path

#### --version &#60;version&#62;

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 &#60;image&#62; &#60;device-type&#62;

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 7cf02a6 --config "$(cat rpi3-config.json)"

### Options

#### --advanced, -v

show advanced configuration options

#### --output, -o &#60;output&#62;

the path to the output JSON file

## os configure &#60;image&#62;

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 remove 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
	$ balena os configure ../path/rpi3.img --app MyApp --version 2.12.7
	$ balena os configure ../path/rpi3.img --app MyFinApp --device-type raspberrypi3

### Options

#### --advanced, -v

show advanced configuration options

#### --application, -a, --app &#60;application&#62;

# Push

## push &#60;applicationOrDevice&#62;

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 balena cloud the given source directory will be sent to the
balena builder, and the build will proceed. This can be used as a drop-in
replacement for git push to deploy.

When building on a local mode device, the given source directory will be built on
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.

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 -s <source directory>

### Options

#### --source, -s &#60;source&#62;

## 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

## local push [deviceIp]

Warning: 'balena local push' 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 push your local changes to a container on a LAN-accessible balenaOS device on the fly.

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
'<source>/.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 &#60;path&#62;

root of project directory to push

#### --destination, -d &#60;path&#62;

destination path on device container

#### --ignore, -i &#60;paths&#62;

#### --skip-logs

do not stream logs after push

#### --verbose, -v

increase verbosity

#### --app-name, -n &#60;name&#62;

#### --build-triggers, -r &#60;files&#62;

comma delimited file list that will trigger a container rebuild if changed

#### --force-build, -f

force a container build and run

#### --env, -e &#60;env&#62;

environment variable (e.g. --env 'ENV=value'). Multiple --env parameters are supported.

## local stop [deviceIp]


Examples:

	$ balena local stop
	$ balena local stop --app-name myapp
	$ balena local stop --all
	$ balena local stop 192.168.1.10
	$ balena local stop 192.168.1.10 --app-name myapp

### Options

#### --all

stop all containers

#### --app-name, -a &#60;name&#62;

# Deploy

## build [source]

Use this command to build an image or a complete multicontainer project
with the provided docker daemon.

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 compose file. If one 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, and if yet that isn't found,
it will try to generate one.

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'
	$ balena build --dockerHost my.docker.host --dockerPort 2376 --ca ca.pem --key key.pem --cert cert.pem

#### --nocache

Don't use docker layer caching when building

#### --squash

Squash newly built layers into a single new layer

## deploy &#60;appName&#62; [image]

Use this command to deploy an image or a complete multicontainer project
to an application, optionally building it first.

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

Unless an image is specified, this command will look into the current directory
(or the one specified by --source) for a compose 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, 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>`.

Note: If building with this command, all options supported by `balena build`
are also supported with this command.

Examples:

	$ balena deploy myApp
	$ balena deploy myApp --build --source myBuildDir/
	$ balena deploy myApp myApp/myImage

### Options

#### --source, -s &#60;source&#62;

Specify an alternate source directory; default is the working directory

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

# 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 &#60;application&#62;

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.
