container-debug

Debug running Docker containers and Compose services. Use when inspecting container logs, exec-ing into running containers, diagnosing networking issues, checking resource usage, debugging multi-stage builds, troubleshooting health checks, or fixing Compose service dependencies.

技能说明

Container Debug

Debug running Docker containers and Compose services. Covers logs, exec, networking, resource inspection, multi-stage builds, health checks, and common failure patterns.

When to Use

Container exits immediately or crashes on start
Application inside container behaves differently than on host
Containers can't communicate with each other
Container is using too much memory or CPU
Multi-stage Docker build produces unexpected results
Health checks are failing
Compose services start in wrong order or can't connect

Container Logs

View and filter logs

# Last 100 lines
docker logs --tail 100 my-container

# Follow (stream) logs
docker logs -f my-container

# Follow with timestamps
docker logs -f -t my-container

# Logs since a time
docker logs --since 30m my-container
docker logs --since "2026-02-03T10:00:00" my-container

# Logs between times
docker logs --since 1h --until 30m my-container

# Compose: logs for all services
docker compose logs -f

# Compose: logs for specific service
docker compose logs -f api db

# Redirect logs to file for analysis
docker logs my-container > container.log 2>&1

# Separate stdout and stderr
docker logs my-container > stdout.log 2> stderr.log

Inspect log driver

# Check what log driver a container uses
docker inspect --format='{{.HostConfig.LogConfig.Type}}' my-container

# If json-file driver, find the actual log file
docker inspect --format='{{.LogPath}}' my-container

# Check log file size
ls -lh $(docker inspect --format='{{.LogPath}}' my-container)

Exec Into Containers

Interactive shell

# Bash (most common)
docker exec -it my-container bash

# If bash isn't available (Alpine, distroless)
docker exec -it my-container sh

# As root (even if container runs as non-root user)
docker exec -u root -it my-container bash

# With specific environment variables
docker exec -e DEBUG=1 -it my-container bash

# Run a single command (no interactive shell)
