Container issues show up at every stage of the stack — at build time, at push time, at pull time, and at runtime. This category covers the full spectrum: from fixing Docker socket permission errors on Jenkins and resolving image pull failures in Kubernetes, to diagnosing why a container keeps crashing after it starts or why it's being killed by the Linux OOM killer.
Troubleshooting
The most common container failures at build, push, pull, and runtime.
Reclaim /var/lib/docker — prune images, containers, volumes and build cache, cap container logs, and fix inode exhaustion.
Fix Docker build failures in CI pipelines — registry auth, COPY path errors, build arguments, and layer caching.
Fix Nginx 404s on route refresh for React/Vue/Angular apps in Docker containers — try_files configuration and Dockerfile setup.
Resolve pods stuck in ContainerCreating — missing secrets, PVC mount failures, CNI plugin errors, and container runtime issues.
Fix Docker socket permission errors on Jenkins agents — the correct way to handle user groups, DinD, and rootless Docker.
Diagnose and resolve image pull failures caused by registry credentials, wrong image tags, or network restrictions.
Step-by-step diagnosis for containers that keep crashing — from misconfigured env vars to missing secrets and bad entrypoints.
Diagnose Out of Memory kills — covers memory limits, JVM heap sizing, memory leaks, sidecar pressure, and VPA right-sizing.
