How do I update a ConfigMap in Kubernetes?
To update a ConfigMap in Kubernetes, you can use the kubectl apply
command with the updated YAML file.
Can I update it directly without a YAML file?
Yes, you can use kubectl edit configmap <configmap-name>
to edit it directly in your terminal.
What happens to the pods using the ConfigMap after I update it?
The pods will not automatically restart. You may need to restart them manually to pick up the changes.
Is there a way to roll back to a previous version of the ConfigMap?
Kubernetes does not provide built-in versioning for ConfigMaps, but you can keep backups of your YAML files to restore previous versions.
