---------------------------------------
Summary: KubernetesPodOperator: Use secretKeyRef or
configMapKeyRef in env_vars
Key: AIRFLOW-3381
URL: https://issues.apache.org/jira/browse/AIRFLOW-3381
Project: Apache Airflow
Issue Type: Improvement
Components: kubernetes
Affects Versions: 1.10.0
Reporter: Arthur Brenaut
The env_vars attribute of the KubernetesPodOperator allows to pass environment
variables as string but it doesn't allows to pass a value from a configmap or a
secret.
I'd like to be able to do
{code:java}
modeling = KubernetesPodOperator(
...
env_vars={
'MY_ENV_VAR': {
'valueFrom': {
'secretKeyRef': {
'name': 'an-already-existing-secret',
'key': 'key',
}
}
},
...
)
{code}
Right now if I do that, Airflow generates the following config
{code:java}
- name: MY_ENV_VAR
value:
valueFrom:
configMapKeyRef:
name: an-already-existing-secret
key: key
{code}
instead of
{code:java}
- name: MY_ENV_VAR
valueFrom:
configMapKeyRef:
name: an-already-existing-secret
key: key
{code}
The _extract_env_and_secrets_ method of the _KubernetesRequestFactory_ could
check if the value is a dictionary and use it directly.
