`spacectl`, the Spacelift CLI

spacectl is a utility wrapping Spacelift's GraphQL API for easy programmatic access in command-line contexts - either in manual interactive mode (in your local shell), or in a predefined CI pipeline (GitHub actions, CircleCI, Jenkins etc).

Installation

Homebrew

You can install spacectl using Homebrew on MacOS or Linux:

brew install spacelift-io/spacelift/spacectl

Arch linux

Install spacectl-bin from the Arch User Repository (AUR):

yay -S spacectl-bin

Disclaimer: The package is community-maintained, please make sure to verify the PKGBUILD before installing/updating.

GitHub Release

Alternatively, spacectl is distributed through GitHub Releases as a zip file containing a self-contained statically linked executable built from the source in this repository. Binaries can be download directly from the Releases page.

Usage on GitHub Actions

We have setup-spacectl GitHub Action that can be used to install spacectl:

steps:
  - name: Install spacectl
    uses: spacelift-io/setup-spacectl@main
    env:
      GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

  - name: Deploy infrastructure
    env:
      SPACELIFT_API_KEY_ENDPOINT: https://mycorp.app.spacelift.io
      SPACELIFT_API_KEY_ID: ${{ secrets.SPACELIFT_API_KEY_ID }}
      SPACELIFT_API_KEY_SECRET: ${{ secrets.SPACELIFT_API_KEY_SECRET }}
    run: spacectl stack deploy --id my-infra-stack

Quick Start

Authenticate using spacectl profile login:

> spacectl profile login my-account
Enter Spacelift endpoint (eg. https://unicorn.app.spacelift.io/): http://my-account.app.spacelift.tf
Select authentication flow:
  1) for API key,
  2) for GitHub access token,
  3) for login with a web browser
Option: 3

Use spacectl 🚀:

> spacectl stack list
Name                          | Commit   | Author        | State     | Worker Pool | Locked By
stack-1                       | 1aa0ef62 | Adam Connelly | NONE      |             |
stack-2                       | 1aa0ef62 | Adam Connelly | DISCARDED |             |

Example

The following screencast shows an example of using spacectl to run a one-off task in Spacelift:

Authentication

spacectl is designed to work in two different contexts - a non-interactive scripting mode (eg. external CI/CD pipeline) and a local interactive mode, where you type commands into your shell. Because of this, it supports two types of credentials - environment variables and user profiles.

We refer to each method of providing credentials as "credential providers" (like AWS), and details of each method are documented in the following sections.

Authenticating using environment variables

The CLI supports the following authentication methods via the environment:

Spacelift API tokens.
GitHub tokens.
Spacelift API keys.

spacectl looks for authentication configurations in the order specified above, and will stop as soon as it finds a valid configuration. For example, if a Spacelift API token is specified, GitHub tokens and Spacelift API keys will be ignored, even if their environment variables are specified.

Spacelift API tokens

Spacelift API tokens can be specified using the SPACELIFT_API_TOKEN environment variable. When this variable is found, the CLI ignores all the other authentication environment variables because the token contains all the information needed to authenticate.

NOTE: API tokens are generally short-lived and will need to be re-created often.

GitHub tokens

GitHub tokens are only available to accounts that use GitHub as their identity provider, but are very convenient for use in GitHub actions. To use a GitHub token, set the following environment variables:

SPACELIFT_API_KEY_ENDPOINT - the URL to your Spacelift account, for example https://mycorp.app.spacelift.io.
SPACELIFT_API_GITHUB_TOKEN - a GitHub personal access token.

Spacelift API keys

To use a Spacelift API key, set the following environment variables:

SPACELIFT_API_KEY_ENDPOINT - the URL to your Spacelift account, for example https://mycorp.app.spacelift.io.
SPACELIFT_API_KEY_ID - the ID of your Spacelift API key. Available via the Spacelift application.
SPACELIFT_API_KEY_SECRET - the secret for your API key. Only available when the secret is created.

More information about API authentication can be found at https://docs.spacelift.io/integrations/api#authenticating-with-the-api.

Authenticating using account profiles

In order to make working with multiple Spacelift accounts easy in interactive scenarios, Spacelift supports account management through the profile family of commands:

❯ spacectl profile
NAME:
   spacectl profile - Manage Spacelift profiles

USAGE:
   spacectl profile command [command options] [arguments...]

COMMANDS:
     current       Outputs your currently selected profile
     export-token  Prints the current token to stdout. In order not to leak, we suggest piping it to your OS pastebin
     list          List all your Spacelift account profiles
     login         Create a profile for a Spacelift account
     logout        Remove Spacelift credentials for an existing profile
     select        Select one of your Spacelift account profiles
     help, h       Shows a list of commands or help for one command

OPTIONS:
   --help, -h  show help (default: false)

Each of the subcommands requires an account alias, which is a short, user-friendly name for each set of credentials (account profiles). Profiles don't need to be unique - you can have multiple sets of credentials for a single account too.

Account profiles support three authentication methods: GitHub access tokens, API keys and login with a browser (API token). In order to authenticate to your first profile, type in the following (make sure to replace ${MY_ALIAS} with the actual profile alias):

❯ spacectl profile login ${MY_ALIAS}
Enter Spacelift endpoint (eg. https://unicorn.app.spacelift.io/):

In the next step, you will be asked to choose which authentication method you are going to use. Note that if your account is using SAML-based SSO authentication, then API keys and login with a browser are your only options. After you're done entering credentials, the CLI will validate them against the server, and assuming that they're valid, will persist them in a credentials file in .spacelift/${MY_ALIAS}. It will also create a symlink in ${HOME}/.spacelift/current pointing to the current profile.

You can switch between account profiles by using spacectl profile select ${MY_ALIAS}. What this does behind the scenes is point ${HOME}/.spacelift/current to the new location. You can also delete stored credetials for a given profile by using the spacectl profile logout ${MY_ALIAS} command.
