Stopping with oc cli
The following are some sample
oc cli
operations to stop a running pod:- oc delete(deleting a specific object inside the OpenShift environment) - A sample command to remove a specific podoc delete pod<pod name>For example:oc delete pod container-gateway-55-gki30d
- oc scale(scale to 0)oc scale --replicas=0 dc container-gateway-dcIf you stop a running pod by scaling to zero, auto-scale is suppressed, even if it was enabled. No new pods are created. Use thescalecommand with caution when auto-scaling is configured.
Stopping with OpenShift Console
- Remove a running pod by clickingdeletefrom the Actions drop-down on the details page of the pod. Note that the deployment configuration will auto-deploy a new pod when you delete it. Refer to the next point on how to work around this.
- Modify the deployment configuration (Applications > Deployments > container-gateway-dc). You can choose to pause the deployment. After pausing the deployment, you can safely remove running pod(s) without the deployment auto-deploying new instances.
- Scale the container-gateway-svc to 0.
- You need to remove auto-scaling to enable manual scaling. Do this by looking in thecontainer-gateway-dcresource and then clickingRemovein the Auto-scaling section.
- In the Overview tab, click the down-arrow next to the pod circle to scale it to 0. This effectively removes all running pods.
