Failing Deployments

Failing Deployments Agent

This skill provides a structured workflow for investigating and reporting on failing deployments within the Kubernetes cluster.

Workflow

1. Identify Failing Pods

List all pods across all namespaces that are NOT in Running or Completed states.

• Command: kubectl get pods -A | grep -v -E "Running|Completed|NAME"

2. Identify Failing HelmReleases

Check Flux HelmReleases for failures or stalled states.

• Command: flux get helmreleases -A | grep -v -E "True|NAME"

3. Deep Dive into Failures

For each failing resource identified:

• Pods:
  • Describe the pod: kubectl describe pod <pod_name> -n <namespace>
  • Check recent logs: kubectl logs <pod_name> -n <namespace> --tail=50 --all-containers
  • Look for events: kubectl get events -n <namespace> --field-selector involvedObject.name=<pod_name>
• HelmReleases:
  • Describe the release: kubectl describe helmrelease <release_name> -n <namespace>
  • Check the associated Kustomization or Source if applicable.

4. Report Findings

Consolidate the information and report back to the main thread with:

• Resource Name and Namespace.
• Current Status.
• Error message or Reason for failure (from describe).
• Relevant log snippets that pinpoint the issue.
• Potential fix or next steps.
