Calrissian spawned pod environment

Calrissian provides several methods to set the spawned pod environment variables.

Using ConfigMaps

The CLI option --env-from-configmap allows settings the spawned pod environment from a ConfigMap. This CLI option can be provided multiple times.

If you have a ConfigMap with:

apiVersion: v1
kind: ConfigMap
metadata:
  name: special-config
  namespace: default
data:
  SPECIAL_LEVEL: very
  SPECIAL_TYPE: charm

And use:

calrissian --env-from-configmap special-config

The Calrissian spawned pods will have SPECIAL_LEVEL: very and SPECIAL_TYPE: charm amongst the environment variables.

Using Secrets

The CLI option --env-from-secret allows settings the spawned pod envionment from a Secret. This CLI option can be provided multiple times.

Using a local file

The CLI option --pod-env-vars allows the user to specify a YAML file containing environment variables to add at runtime to the Pods submitted.

Example:

calrissian --pod-env-vars a-local-file

Where the local file a-local-file contains:

SPECIAL_LEVEL: very
SPECIAL_TYPE: charm
