Docker agent configuration reference#

This reference describes the various configuration options Dagster+ currently supports for Docker agents.

Environment variables and secrets#

Using the container_context.docker.env_vars property, you can include environment variables and secrets in the Docker container associated with a specific code location. For example:

# dagster_cloud.yaml
locations:
  - location_name: cloud-examples
    image: dagster/dagster-cloud-examples:latest
    code_source:
      package_name: dagster_cloud_examples
    container_context:
      docker:
        env_vars:
          - DATABASE_NAME
          - DATABASE_USERNAME=hooli_testing

The container_context.docker.env_vars property is a list, where each item can be either KEY or KEY=VALUE. If only KEY is specified, the value will be pulled from the local environment.
