# Build and Debug Docker Workflows

Containerizing applications consistently requires many connected Docker decisions. This skill guides builds, Compose services, diagnostics, optimization, and production hardening with reusable examples.

## Capabilities

- Creates multi-stage Dockerfile plans for Node.js, Python, Go, Java, and Rust applications.
- Designs Docker Compose services with dependencies, networks, volumes, health checks, and environment-specific overrides.
- Explains layer caching, BuildKit cache mounts, minimal images, and non-root runtime users.
- Provides Docker commands for building, running, inspecting, logging, restarting, and troubleshooting containers.
- Includes a Bash helper for health checks, backups, cleanup, network inspection, and image analysis.
- Reviews container configurations for production readiness, resource limits, monitoring, and deployment practices.

## Use Cases

- Containerize a New Service: Create a compact, non-root multi-stage image with dependency caching and a practical health check.
- Standardize Local Environments: Define repeatable application, database, cache, and worker services with Compose networks and volumes.
- Prepare a Production Deployment: Review images and Compose settings for security, observability, resource limits, and controlled updates.

## Prompt Templates

### Create a Dockerfile

```
Create a multi-stage Dockerfile for [application] using [runtime]. Use a non-root user, add a health check, and explain each stage.
```

### Compose a Local Stack

```
Design a Docker Compose setup for [services]. Include isolated networks, named volumes, health checks, and development overrides.
```

### Diagnose a Container

```
Diagnose [symptom] for container [name]. Provide ordered inspection steps, expected evidence, and reversible fixes before destructive actions.
```

### Harden a Deployment

```
Audit these Docker files for secrets, privileges, network exposure, mutable images, resource limits, and recovery risks. Prioritize fixes by impact.
```

## Limitations

- Examples require adaptation to the application, directory structure, ports, and package manager.
- The helper script requires local Docker access and can perform destructive cleanup operations.
- The included Compose example contains development credentials and must not be deployed unchanged.
- The skill does not replace vulnerability scanning, secret management, or an orchestration platform.

## Best Practices

- Pin reviewed image versions or digests and update them through a controlled process.
- Keep secrets outside images and Compose files by using a dedicated secret manager.
- Preview cleanup and deployment effects, then require confirmation before data-changing commands.

## Anti Patterns

- Do not deploy example passwords, fallback secrets, or exposed administration services.
- Do not use mutable latest tags for production images.
- Do not run broad prune commands before reviewing containers, images, networks, and volumes.

## Security Audit

- Audited at: 2026-07-23T09:10:08.139\+00:00
- Summary: Most static alerts are documentation syntax, local health checks, or protective ignore rules. Confirmed risks include predictable secrets, external diagnostics, credential disclosure, destructive cleanup, exposed Elasticsearch, and mutable images.
