Known issues

Learn about the known issues in this release of CSA Operator.

SSB Flink job deployment can fail on non-OpenShift clusters

On non-OpenShift clusters, SSB Flink job deployment can fail with the following error:

 CreateContainerConfigError: container has runAsNonRoot and image will run as root. A default non-root user is not set so the container starts as root but this is forbidden by the security policy.

Remove the FlinkDeployment resource related to SSB:

kubectl -n [***NAMESPACE***] delete flinkdeployment [***DEPLOYMENT NAME***]

Open the SSB configurations to edit:

kubectl -n [***NAMESPACE***] edit cm ssb-config

Add the highlighted line to the security-context.yaml entry:
```
allowPrivilegeEscalation: false
  capabilities:
    drop:
    - ALL
  runAsNonRoot: true
  seccompProfile:
    type: RuntimeDefault
  runAsUser: 9999
```
It can take a couple of minutes for the changes to take effect after modifying the ConfigMap.
Execute the SQL job from SSB again.
