docker-debugger from onewave-ai/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Debug Docker containers, fix Dockerfile issues, optimize images, and troubleshoot docker-compose. Use when having Docker problems, container issues, or optimizing Docker builds.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# Docker Debugger
## Instructions
When debugging Docker issues:
1. **Identify the problem type**: Build, runtime, networking, or performance
2. **Gather information** using diagnostic commands
3. **Analyze logs and errors**
4. **Apply fixes**
## Diagnostic Commands
```bash
# Check running containers
docker ps -a
# View container logs
docker logs <container_id> --tail 100 -f
# Inspect container
docker inspect <container_id>
# Check resource usage
docker stats
# View container processes
docker top <container_id>
# Execute shell in running container
docker exec -it <container_id> /bin/sh
# Check Docker disk usage
docker system df
# View build history
docker history <image_name>
```
## Common Issues & Solutions
### 1. Container exits immediately
```bash
# Check exit code
docker inspect <container_id> --format='{{.State.ExitCode}}'
# View last logs
docker logs <container_id>
```
**Fixes**:
- Ensure CMD/ENTRYPOINT runs a foreground process
- Check for missing dependencies
- Verify environment variables
### 2. Build fails
```dockerfile
# Use multi-stage builds for smaller images
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .

How to install
mdr add onewave-ai/claude-skills/docker-debugger@sha256:a4a4d766048c82bcThe line at the top of this page pins the label git:20260225.309ae7a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
