Focused, hands-on DevOps and server-side problems with hints, feedback, and automated solution checks.
A Job manifest at /home/laborant/batch-job.yaml is exiting with a non-zero exit status. The Job has limited retries configured. Inspect the cluster and the manifest to find the bug, fix it, and reapply.
A webapp deployment in the prod namespace is stuck in CrashLoopBackOff. The application's startup probe checks that its existing config directory is intact before the container is marked healthy. Fix the deployment so configuration is injected correctly and the pod reaches Running state with its health check endpoint responding on port 8080.
A Deployment is stuck with Pods in ContainerCreating state because the required ConfigMap was not created. Fix the issue to make the application accessible.
Troubleshoot and update a Kubernetes DaemonSet so that its Pods run on all nodes in the cluster, including the control plane.
A web application is deployed but the website is not accessible. Investigate and fix the issue.
