How do you troubleshoot Docker container issues?
Detailed Explanation
Docker troubleshooting strategies: 1) Check container status: docker ps -a (List all containers), docker logs (View logs), docker inspect (Detailed info), 2) Debug running containers: docker exec -it /bin/bash (Interactive shell), docker stats (Resource usage), docker top (Running processes), 3) Network troubleshooting: docker network ls (List networks), docker network inspect bridge (Network details), docker port (Port mappings), 4) Common issues: Container exits immediately (Check CMD/ENTRYPOINT), Port not accessible (Verify port mapping and firewall), Out of disk space (Clean up with docker system prune), Permission denied (Check user permissions and SELinux).
