- Add fleet(s) commands and -f, --fleet flags as aliases to the app(s) commands and -a, --app, --application flags. - Conditionally rename column/row headers and JSON object properties from 'application' to 'fleet', with some variations. - Print warning messages regarding the renaming, provided that stderr is attached to an interactive terminal.

balena CLI
The official balena Command Line Interface.
About
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:
-
- Install additional packages with the command:
pacman -S git gcc make openssh p7zip
- 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.
- Install additional packages with the command:
-
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_comp
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 fleet. 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
orhttps
), 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'
- A string in URL format, e.g.
-
The
HTTPS_PROXY
and/orHTTP_PROXY
environment variables, in the same URL format asBALENARC_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 theBALENARC_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
.
Command reference documentation
The full CLI command reference is available on the web or by running balena help --verbose
.

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.
