Podman Debug

Diagnose container issues, inspect logs, and troubleshoot Podman containers.

Instructions

Run podman ps -a to see all containers and their states
Identify the problematic container by name or ID
Check container logs with podman logs <container>
Inspect container config with podman inspect <container>
If needed, exec into running container: podman exec -it <container> /bin/sh
Report findings and suggest fixes

Common diagnostic commands

# Container status and health
podman ps -a --format "table {{.Names}}\t{{.Status}}\t{{.Ports}}"
podman healthcheck run <container>

# Logs with timestamps
podman logs -t --since 10m <container>
podman logs -f <container>  # follow

# Resource usage
podman stats --no-stream

# Inspect specific fields
podman inspect -f '{{.State.ExitCode}}' <container>
podman inspect -f '{{.State.Error}}' <container>
podman inspect -f '{{json .NetworkSettings}}' <container>

# Container processes
podman top <container>

# Events
podman events --since 1h --filter container=<name>

Common issues and solutions

Symptom	Check	Likely Cause
Exit code 137	`dmesg \| grep -i oom`	OOM killed - increase memory
Exit code 1	`podman logs`	Application error
Exit code 126	Entrypoint permissions	`chmod +x` on entrypoint
Exit code 127	Entrypoint path	Command not found in image
Network unreachable	`podman network ls`	Network not attached

Rules

MUST check logs before suggesting fixes
MUST report exit codes and their meaning
Never restart containers without user approval
Never remove containers or volumes without explicit request
Always suggest --rm flag for debug containers
