Debugging Applications

Issues with applications are often due to issues with the underlying Pods. You can use kubectl commands to get, find logs for, and delete pods as necessary. Note that Plural automatically configures kubectl for use with your Plural cluster.

With Plural CLI

To find Pods related to an application with the CLI, you can run:

kubectl get pods -n <application-name>

If you see failed Pods, you can get the logs for the Pods by running:

kubectl logs -n <application-name> <name-of-pod>

We also curate a list of helpful logging shortcuts for each application, which you can use the plural logs subcommand for, eg with

plural logs list <application> # shows all log tails available
plural logs tail <application> <name> # tails that specific log

To delete problematic Pods, run:

kubectl delete pod <pod-name>

In most cases, kubernetes will restart the pod for you. You can always also run plural bounce to regenerate your deleted Pods.

With Plural Console

If you have the Plural Console installed, you can debug your Kubernetes Pods with the following steps:

1. Navigate to the Components tab and click on the failing component

2. Scroll to the Pods section at the bottom of the screen and hit the red trash can button located on the right of the screen to delete the failing Pod.

3. Head back to the Builds tab in the sidebar and click the Bounce button in the top right to redeploy your deleted Pods.
