astro deployment variable update


For a given Deployment on Astro, use astro deployment variable update to update the value of an existing environment variable via the Astro CLI. To do so, you can either:

  • Manually enter a new --value in your command line for a given --key, or
  • Modify the value of one or more environment variables in a .env file and load that file with --load.

If you choose to specify --key and --value instead of loading a file, you can only update one environment variable at a time.

This command is functionally identical to editing and saving the value of an existing environment variable via the Cloud UI. For more information on environment variables, see Set environment variables on Astro.


astro deployment variable update

To run this command in an automated process such as a CI/CD pipeline, set the following OS-level environment variables in a way that the Astro CLI can access them:


After setting the variables, this command works for a Deployment without you having to manually authenticate to Astronomer. Astronomer recommends storing ASTRONOMER_KEY_SECRET as a secret before using it to programmatically update production-level Deployments.
