Manage Deployments programmatically using Deployment files

Manage an Astro Deployment using a Deployment file in YAML or JSON format

You can configure Deployments programmatically using Deployment files and Deployment template files. Deployment files are used to update the same Deployment programmatically, and Deployment template files are used to create new Deployments based on a single template.

Managing Deployments with files is essential to automating Deployment management at scale. For example, you can:

• Create a template file in a central GitHub repository and use it as a source of truth for new Deployments that fit a particular use case. For example, you can standardize your team’s development Deployments by creating a template file with configurations for that type of Deployment.
• Create a Deployment file that represents the configurations of an existing Deployment and store it in your GitHub repository. You can make changes to this file to update a Deployment using CI/CD, which maintains the history of your changes.

Use this document to learn how to create and manage Deployment files and Deployment template files. See the Deployment file reference for a list of configurable Deployment file values. When you’re ready to programmatically run Deployment file workflows, see Authenticate your workflow.

Create a template file or Deployment file

To create a template file based on an existing Deployment, run the following command:

astro deployment inspect <deployment-id> --template > <your-deployment-template-file-name>.yaml

To create a Deployment file based on an existing Deployment, run the following command:

astro deployment inspect <deployment-id> > <your-deployment-file-name>.yaml

Alternatively, you can manually create a template file without using an existing Deployment as explained in Create a Deployment using a template file.

Create a Deployment using a template file

These are the minimum values required to create a Deployment using a template file. Any configurations not specified are set to default values. To add more configurations, see

Deployment file reference

.

1. Copy one of the following templates to a local yaml file:

Standard cluster

deployment:
    configuration:
        name: <your-deployment-name>
        deployment_type: HOSTED_SHARED
        cloud_provider: aws
        description: <deployment-description>
        runtime_version: 9.1.0
        dag_deploy_enabled: true
        executor: CeleryExecutor
        cluster_name: us-east-1
        region: us-east-1
        workspace_name: <your-workspace-name>
        scheduler_size: small

Note that for Deployments on a standard cluster, the region and cluster-name parameters must both contain the region name for the standard cluster. See Available regions for your cloud provider.

Dedicated cluster

  deployment:
      configuration:
          name: <your-deployment-name>
          deployment_type: HOSTED_DEDICATED
          cloud_provider: aws
          description: <deployment-description>
          runtime_version: 9.1.0
          dag_deploy_enabled: true
          executor: KubernetesExecutor
          cluster_name: <your-cluster-name>
          region: us-east-1
          workspace_name: <your-workspace-name>
          scheduler_size: small

The cluster_name field must include the name of the dedicated cluster that exists in your Astro Organization.

2. Adjust the template file values for the Deployment you want to create. When working with template files, keep the following in mind:

   • The name field must include a unique name within the Workspace.

   • The workspace_name field must include a valid Workspace name that exists in your Astro Organization.

   • The possible values for cloud_provider, executor, and scheduler_size are the same possible values when you create a Deployment with astro deployment create.

   • See Airflow and Astro Runtime version parity to choose your Astro Runtime version.

See Deployment file reference for a list of all configurable Deployment template file values.

3. Run the following command to create the Deployment:

   astro deployment create --deployment-file <your-deployment-file-name>
   

4. (Optional) Either open the Astro UI or run the following command to confirm that you successfully created your Deployment:

   astro deployment list
   

5. (Optional) Reconfigure any Airflow connections or variables from the Deployment that you copied into the template file. Airflow connections and variables cannot be configured using template files. See Manage connections in Airflow.

Update a Deployment using a Deployment file

A Deployment file is a complete snapshot of an existing Deployment at the point you inspected it. It’s similar to a template file, but also contains your Deployment’s name, description, and metadata. In the same way you use a template file to create a new Deployment, you use a Deployment file to update an existing Deployment with a new set of configurations.

When you update a Deployment with a Deployment file, keep the following in mind:

• You can’t change the cluster or Workspace the Deployment runs on. To transfer a Deployment to a different Workspace, see Transfer a Deployment.
• You can’t change the Astro Runtime version of the Deployment. To upgrade Astro Runtime, you must update the Dockerfile in your Astro project. See Upgrade Astro Runtime.
• Environment variables marked as secret in the Astro UI will be exported with a blank value to your Deployment file. To redeploy using the Deployment file, you either need to provide the value again in the Deployment file or delete the object for the variable. Otherwise, astro deployment create will fail. See deployment.environment_variables for more details.

When you update a Deployment with a Deployment file, you must push a complete Deployment file that lists all of your existing worker queues. If a worker queue exists on Astro but doesn’t exist in your Deployment file, the worker queue is deleted when you push your Deployment file.

To update a Deployment using a Deployment file:

1. Inspect an existing Deployment and create a Deployment file for its current configurations:

astro deployment inspect <deployment-id> > <your-deployment-file-name>.yaml

2. Modify the Deployment file and save your changes. See Deployment file reference for fields that you can modify.

3. Update your Deployment according to the configurations in the Deployment file:

astro deployment update <deployment-id> --deployment-file <your-deployment-file>

4. (Optional) Confirm that your Deployment was updated successfully by running the following command. You can also go to the Deployment page in the Astro UI to confirm the new values.

astro deployment inspect <deployment-id>
