how do i current directory as an env var in the

dagster.yaml

file?

To use the current directory as an environment variable in the

dagster.yaml

file, you would typically set an environment variable in your shell to the current directory and then reference that environment variable in your

dagster.yaml

. Here's how you can do it step by step: 1. Set an environment variable in your shell to the current directory. For example, in a Unix-like shell, you could use the following command:

sh    export DAGSTER_HOME=$(pwd)

This sets the

DAGSTER_HOME

environment variable to the current working directory. 2. In your

dagster.yaml

file, you can then reference this environment variable using the syntax provided by your operating system's shell. For example:

yaml    instance:      root_directory: ${DAGSTER_HOME}

Please note that the exact syntax for referencing environment variables can vary depending on the shell and operating system you are using. The example above uses Unix shell syntax. Keep in mind that the

dagster.yaml

file is used to configure the Dagster instance, and the

DAGSTER_HOME

environment variable is used by Dagster to locate this file and other instance-related data. If you want to use the current directory as the

DAGSTER_HOME

, you need to ensure that the

dagster.yaml

file is located in the current directory or in a directory structure that Dagster expects based on the

DAGSTER_HOME

setting. If you encounter any issues or need further clarification, please refer to the documentation or reach out for more specific guidance.

@Scout for my

dagster.yaml

within the

DockerRunLauncher

how do I set my

/absolute/path/to/local/repo.py

as an env variable?

To set an absolute path to your

repo.py

as an environment variable for use within the

DockerRunLauncher

configuration in your

dagster.yaml

file, you can follow these steps: 1. First, set an environment variable in your shell to the absolute path of your

repo.py

. For example:

sh    export REPO_PY_PATH=/absolute/path/to/local/repo.py

2. Then, in your

dagster.yaml

file, reference this environment variable using the appropriate syntax for environment variable substitution. According to the documentation, you can use the following syntax in your

dagster.yaml

to reference an environment variable:

yaml    run_launcher:      module: dagster_docker      class: DockerRunLauncher      config:        image: "my-docker-image"        registry: "my-docker-registry"        env_vars:          - "REPO_PY_PATH"        # ... other configuration options

In this configuration,

REPO_PY_PATH

is the name of the environment variable that contains the absolute path to your

repo.py

. When the

DockerRunLauncher

launches a new Docker container, it will pass this environment variable to the container. Please ensure that the environment variable

REPO_PY_PATH

is set in the environment where the Dagster process (e.g., Dagit or the Dagster daemon) is running, so that it can be correctly passed to the Docker container. If you need to use the value of the

REPO_PY_PATH

environment variable within the Docker container (for example, to specify the location of your code when running a Dagster job), you would access it using the environment variable syntax specific to the shell or application within the container. Keep in mind that the exact configuration might vary depending on your specific use case and deployment setup. If you encounter any issues or need further assistance, please refer to the documentation or reach out for more specific guidance.

@Scout please change this

      port:
        env: DAGSTER_POSTGRES_PORT
      params:
        options: -csearch_path=dagster-internal

To load the

mylocalrepo:/opt/dagster/app/

volume mapping from an environment variable, you would first need to set an environment variable in your environment that contains the path to

mylocalrepo

. For example, you could set an environment variable named

MY_LOCAL_REPO_PATH

to the desired path. Here's how you can modify the

dagster.yaml

file to use an environment variable for the volume mapping:

yaml scheduler:   module: dagster.core.scheduler   class: DagsterDaemonScheduler  run_coordinator:   module: dagster.core.run_coordinator   class: QueuedRunCoordinator  run_launcher:   module: dagster_docker   class: DockerRunLauncher   config:     env_vars:       - DAGSTER_POSTGRES_USER       - DAGSTER_POSTGRES_PASSWORD       - DAGSTER_IRIS_DATA_POSTGRES_DATABASE       - DAGSTER_POSTGRES_HOST       - DAGSTER_POSTGRES_PORT       - AIRBYTE_HOST       - AIRBYTE_PORT       - AIRBYTE_USERNAME       - AIRBYTE_PASSWORD       - DAGSTER_CURRENT_IMAGE       - MY_LOCAL_REPO_PATH  # Add the environment variable for the local repo path     container_kwargs:       volumes:         - /var/run/docker.sock:/var/run/docker.sock         - /tmp/io_manager_storage:/tmp/io_manager_storage         - "${MY_LOCAL_REPO_PATH}:/opt/dagster/app/"  # Use the environment variable in the volume mapping storage:   postgres:     postgres_db:       hostname:         env: DAGSTER_POSTGRES_HOST       username:         env: DAGSTER_POSTGRES_USER       password:         env: DAGSTER_POSTGRES_PASSWORD       db_name:         env: DAGSTER_IRIS_DATA_POSTGRES_DATABASE       port:         env: DAGSTER_POSTGRES_PORT       params:         options: -csearch_path=dagster-internal

In the

run_launcher

configuration, the

volumes

section now includes a reference to the

MY_LOCAL_REPO_PATH

environment variable. When the

DockerRunLauncher

launches a container, it will substitute the value of

MY_LOCAL_REPO_PATH

with the actual path you've set in your environment. Please ensure that the

MY_LOCAL_REPO_PATH

environment variable is set in the environment where the Dagster process is running. This will allow the

DockerRunLauncher

to correctly pass the volume mapping to the Docker container.
