balena CLI Installation Instructions

There are 3 options to choose from to install balena's CLI:

  • Executable Installer: the easiest method, using the traditional graphical desktop application installers for Windows and macOS (coming soon for Linux users too).
  • Standalone Zip Package: these are plain zip files with the balena CLI executable in them. Recommended for scripted installation in CI (continuous integration) environments.
  • NPM Installation: recommended for developers who may be interested in integrating the balena CLI in their existing Node.js projects or workflow.

Some specific CLI commands have a few extra installation steps: see section Additional Dependencies.

Windows users: We now have a YouTube video tutorial for installing and getting started with the balena CLI on Windows!

Executable Installer

Please note: the executable installers are in beta status (recently introduced).

  1. Download the latest installer from the releases page. Look for a file name that ends with "installer-BETA", for example:
    balena-cli-v10.13.6-windows-x64-installer-BETA.exe
    balena-cli-v10.13.6-macOS-x64-installer-BETA.pkg
  2. Double click to run. Your system may raise a pop-up warning that the installer is from an "unknown publisher" or "unidentified developer". Check the following instructions for how to get through the warnings: Windows or macOS. (We are looking at how to get the installers digitally signed to avoid the warnings.)

After the installation completes, close and re-open any open command terminal windows so that the changes made by the installer to the PATH environment variable can take effect. Check that the installation was successful by running these commands:

  • balena - should print the balena CLI help
  • balena version - should print the installed CLI version

Note: If you had previously installed the CLI using a standalone zip package, it may be a good idea to check your system's PATH environment variable for duplicate entries, as the terminal will use the entry that comes first. Check the Standalone Zip Package instructions for how to modify the PATH variable.

By default, the CLI is installed to the following folders:

OS Folders
Windows: C:\Program Files\balena-cli\
macOS: /usr/local/lib/balena-cli/
/usr/local/bin/balena

Standalone Zip Package

  1. Download the latest zip file from the releases page. Look for a file name that ends with the word "standalone", for example:
    balena-cli-v10.13.6-linux-x64-standalone.zip
    balena-cli-v10.13.6-macOS-x64-standalone.zip
    balena-cli-v10.13.6-windows-x64-standalone.zip
  2. Extract the zip file contents to any folder you choose. The extracted contents will include a balena-cli folder.
  3. Add the balena-cli folder to the system's PATH environment variable.
    See instructions for: Linux | macOS | Windows

To update the CLI to a new version, download a new release zip file and replace the previous installation folder. To uninstall, simply delete the folder and edit the PATH environment variable as described above.

NPM Installation

If you are a Node.js developer, you may wish to install the balena CLI via npm. The npm installation involves building native (platform-specific) binary modules, which require some additional development tools to be installed first:

  • Node.js version 8 or 10 (v12 has not been thoroughly tested yet)
  • Python 2.7
  • g++ compiler
  • make
  • git
  • On Windows, the windows-build-tools npm package should be installed too, running the following command in an administrator console (available as "Command Prompt (Admin)" or "Windows PowerShell (Admin)" when typing Windows+X):
    npm install -g --production windows-build-tools

With those in place, the CLI installation command is:

$ 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.

On some Linux distributions like Ubuntu, users often report permission or otherwise mysterious errors when using the system Node / npm packages installed via "apt-get". We suggest using nvm instead. Check this sample Dockerfile for installing the CLI on an Ubuntu Docker image: https://gist.github.com/pdcastro/5d4d96652181e7da685a32caf629dd44

Additional Dependencies

  • The balena ssh command requires a recent version of the ssh command-line tool to be available:

    • macOS and Linux usually already have it installed. Otherwise, search for the available packages on your specific Linux distribution, or for the Mac consider the Xcode command-line tools or homebrew.

    • Microsoft started distributing an SSH client with Windows 10, which we understand is automatically installed through Windows Update, but can be manually installed too (more information). For other versions of Windows, there are several ssh/OpenSSH clients provided by 3rd parties.

    • If you need SSH to work behind a proxy, you will also need to install proxytunnel (available as a proxytunnel package for Ubuntu, for example). Check the README file for proxy configuration instructions.

  • The balena sync command (deprecated) currently requires rsync (>= 2.6.9) to be installed:

    • Linux: apt-get install rsync
    • macOS: Xcode command-line tools or homebrew
    • Windows: One option is to use the MinGW shell and install the msys-rsync package. Check the README file for other shell options under Windows.

Configuring SSH keys

The balena ssh command requires an SSH key to be added to your balena account. If you had already added a SSH key in order to deploy with 'git push', then you are probably done and may skip this section. You can check whether you already have an SSH key in your balena account with the balena keys command, or by visiting the balena web dashboard, clicking on your name -> Preferences -> SSH Keys.

Note: 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.

If you don't have an SSH key in your balena account:

  • If you have an existing SSH key in your computer that you would like to use, you can add it to your balena account through the balena web dashboard (Preferences -> SSH Keys), or through the CLI itself:
# Windows 10 (cmd.exe prompt) example:
$ balena key add MyKey %userprofile%\.ssh\id_rsa.pub
# Linux / macOS example:
$ balena key add MyKey ~/.ssh/id_rsa.pub
  • To generate a new key, you can follow GitHub's documentation, skipping the step about adding the key to your GitHub account, and instead adding the key to your balena account as described above.
You can’t perform that action at this time.
