Hi Edgar,
this is how we've been doing it and it's working well.
apiVersion: flink.apache.org/v1beta1
kind: FlinkDeployment
metadata:
namespace: flink
name: redacted-job
spec:
image: flink:1.15-java11
flinkVersion: v1_15
flinkConfiguration:
taskmanager.numberOfTaskSlots: "1"
kubernetes.env.secretKeyRef:
"env:DJANGO_TOKEN,secret:special-secret-token,key:token"
Unfortunately, I don't think this is in the docs yet.
