astro deployment variable update

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

  • Manually enter a new key=value pair for an existing key directly in the command.
  • Modify the value of one or more environment variables in a .env file and load that file with --load.

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

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.
