The Bitwarden sm-action repository contains the source code for the Secrets Manager GitHub Action.

Use the GitHub action, bitwarden/sm-action, to retrieve secrets from the Bitwarden Secrets Manager for use inside GitHub Actions.

The bitwarden/sm-action will add retrieved secrets as masked environment variables inside a given GitHub action.

Review GitHub's recommendations for security hardening GitHub Actions when using sensitive secrets.

To use the action, add a step to your GitHub workflow using the following syntax:

- name: Step name
  uses: bitwarden/sm-action@v1
  with:
    access_token: ${{ secrets.ACCESS_TOKEN }}
    secrets: |
      SECRET_ID > ENVIRONMENT_VARIABLE_NAME

• access_token

  The machine account access token for retrieving secrets.

  Use GitHub's encrypted secrets to store and retrieve machine account access tokens securely.

• secrets

  One or more secret Ids to retrieve and the corresponding GitHub environment variable name to set.

  GitHub environment variables have stricter naming requirements than Bitwarden secrets.

  So the bitwarden/sm-action requires specifying an environment variable name for each secret retrieved in the following format:

  secrets: |
      SECRET_ID > ENVIRONMENT_VARIABLE_NAME
  

  Example

      secrets: |
          00000000-0000-0000-0000-000000000000 > TEST_EXAMPLE
  

• base_url

  (Optional) For self-hosted bitwarden instances provide your https://your.domain.com

  If this optional parameter is provided the parameters identity_url and api_url are not required.

  The GitHub action will use BASE_URL/identity and BASE_URL/api for the identity and api endpoints.

• identity_url

  (Optional) For self-hosted bitwarden instances provide your https://your.domain.com/identity

  The default value will use https://identity.bitwarden.com

• api_url

  (Optional) For self-hosted bitwarden instances provide your https://your.domain.com/api

  The default value will use https://api.bitwarden.com
