Environment Variables Injected by Coiled

Coiled injects the following environment variables into your cluster:

• COILED_AUTH_TOKEN: Temporary Coiled authentication token, valid while the cluster is running.

• COILED_CLUSTER_HOSTNAME: Hostname (e.g., cluster-xyz.dask.host) for the cluster scheduler.

• COILED_CLUSTER_ID: ID of the cluster. A useful value to log to other systems for cross-referencing.

• COILED_CLUSTER_NAME: The name of the cluster, as shown in the dashboard.

• COILED_INSTANCE_ID: The VM ID, as understood by the cloud provider.

• COILED_WORKSPACE_SLUG: The slug of the workspace the cluster belongs to.

Clusters started with coiled batch run inject additional environment variables. You can find them in the Batch documentation.
