Container maintenance procedure

Check how to avoid POD restart during maintenance.

The POD status check of a Kubernetes-based environment is based on Liveness Probe; the latter checks if all processes are active, if one or more processes are not active, the POD is automatically restarted. Therefore, in case of maintenance, manually stopping the HCL Workload Automation processes, the Dynamic Workload Console processes, or the dynamic agent processes causes a POD restart.

To avoid a PD restart during maintenance:
  • In the selected POD, create the following file: /opt/wautils/wa_maintenance
  • Stop the processes listed above and perform all the steps needed for the maintenance
  • Restart the stopped processes
  • Delete the /opt/wautils/wa_maintenance file
