Docker Skill

Provides comprehensive Docker container building and management capabilities for the Golden Armada AI Agent Fleet Platform.

When to Use This Skill

Activate this skill when working with:

• Building Docker images
• Writing Dockerfiles
• Container management
• Docker Compose configurations
• Multi-platform builds
• Container optimization

Quick Reference

Build Commands

```bash

Build image

docker build -t : -f docker build -t golden-armada/claude-agent:latest -f deployment/docker/claude/Dockerfile .

Multi-platform build

docker buildx build --platform linux/amd64,linux/arm64 -t : .

Build with args

docker build --build-arg VERSION=1.0.0 -t : . ```

Run Commands

```bash

Run container

docker run -d -p 8080:8080 --name agent golden-armada/claude-agent:latest

Run with environment

docker run -e ANTHROPIC_API_KEY=$ANTHROPIC_API_KEY golden-armada/claude-agent:latest

Run interactively

docker run -it --rm golden-armada/claude-agent:latest /bin/sh

Run with volume

docker run -v $(pwd):/app golden-armada/claude-agent:latest ```

Management

```bash

List

docker ps -a docker images

Cleanup

docker system prune -f docker image prune -a -f docker container prune -f

Logs

docker logs --tail=100 -f

Exec

docker exec -it /bin/sh ```

Dockerfile Best Practices

```dockerfile

1. Use specific base image

FROM python:3.11-slim

2. Set working directory

WORKDIR /app

3. Copy requirements first (layer caching)

COPY requirements.txt . RUN pip install --no-cache-dir -r requirements.txt

4. Copy application

COPY . .

5. Create non-root user

RUN useradd -m appuser && chown -R appuser:appuser /app USER appuser

6. Expose port

EXPOSE 8080

7. Health check

HEALTHCHECK --interval=30s --timeout=3s
CMD curl -f http://localhost:8080/health || exit 1

8. Define entrypoint

CMD ["gunicorn", "-b", "0.0.0.0:8080", "agent:app"] ```

Multi-Stage Build Example

```dockerfile

Build stage

FROM node:20-alpine AS builder WORKDIR /app COPY package*.json ./ RUN npm ci COPY . . RUN npm run build

Production stage

FROM node:20-alpine WORKDIR /app COPY --from=builder /app/dist ./dist COPY --from=builder /app/node_modules ./node_modules USER node EXPOSE 3000 CMD ["node", "dist/index.js"] ```

Golden Armada Docker Commands

deployment/docker/claude/

Build orchestrator

docker build -f deployment/docker/orchestrator/Dockerfile
-t golden-armada/orchestrator:latest
deployment/docker/orchestrator/

Run locally

docker run -p 8080:8080
-e ANTHROPIC_API_KEY=$ANTHROPIC_API_KEY
golden-armada/claude-agent:latest ```
