James Busche commented on FLINK-30577:
--------------------------------------
So document that they should edit the configmap and restart the operator? I
just tried that and it worked:
oc edit cm flink-operator-config -n openshift-operators
{quote}change:
# kubernetes.operator.user.artifacts.base.dir: /opt/flink/artifacts
to
kubernetes.operator.user.artifacts.base.dir: /tmp/flink/artifacts
{quote}
Restart the operator pod:
oc get pods -n openshift-operators
{quote}NAME READY STATUS RESTARTS
AGE
flink-kubernetes-operator-5f5bb584db-t75ts 2/2 Running 0 4m45s
{quote}
oc delete pod flink-kubernetes-operator-5f5bb584db-t75ts -n openshift-operators
Then in a non-default namespace the session jobs work:
oc get flinksessionjobs -n jim
{quote}NAME JOB STATUS RECONCILIATION STATUS
basic-session-job-example RUNNING DEPLOYED
basic-session-job-example2 RUNNING DEPLOYED
basic-session-job-only-example RUNNING DEPLOYED

> Key: FLINK-30577
> URL: https://issues.apache.org/jira/browse/FLINK-30577
> Project: Flink
> Issue Type: Bug
> Components: Kubernetes Operator
> Affects Versions: kubernetes-operator-1.3.0
> Reporter: James Busche
> Priority: Major
>
> [~tagarr] has pointed out an issue with using the /opt/flink/artifacts
> filesystem on OpenShift in non-default namespaces. The OpenShift permissions
> don't allow write to /opt.
> ```
> org.apache.flink.util.FlinkRuntimeException: Failed to create the dir:
> /opt/flink/artifacts/jim/basic-session-deployment-only-example/basic-session-job-only-example
> ```
> A few ways to solve the problem are:
> 1. Remove the comment on line 34 here in
> [flink-conf.yaml|https://github.com/apache/flink-kubernetes-operator/blob/main/helm/flink-kubernetes-operator/conf/flink-conf.yaml#L34]
> and change it to: /tmp/flink/artifacts
> 2. Append this after line 143 here in
> [values.yaml|https://github.com/apache/flink-kubernetes-operator/blob/main/helm/flink-kubernetes-operator/values.yaml#L142]:
> kubernetes.operator.user.artifacts.base.dir: /tmp/flink/artifacts
> 3. Changing it in line 142 of
> [KubernetesOperatorConfigOptions.java|https://github.com/apache/flink-kubernetes-operator/blob/main/flink-kubernetes-operator/src/main/java/org/apache/flink/kubernetes/operator/config/KubernetesOperatorConfigOptions.java#L142]
> like this:
> .defaultValue("/tmp/flink/artifacts")
> and then rebuilding the operator image.
