docker SKILL.md skillA

docker from mjunaidca/mjs-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

mdr add mjunaidca/mjs-agent-skills/docker@git:20260124.14c9905

Pins git:20260124.14c9905 in mdr.lock. Pin the fingerprint instead.

Production-grade Docker containerization for Python and Node.js applications. This skill should be used when users ask to containerize applications, create Dockerfiles, dockerize projects, or set up Docker Compose. Auto-detects project structure, analyzes .env for secrets, validates security, and generates tested Dockerfiles.

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.

What the file says

# Docker

Production-grade Docker containerization with security-first defaults.

## Resource Detection & Adaptation

**Before generating Dockerfiles/Compose, detect the environment:**

```bash
# Detect host machine memory
sysctl -n hw.memsize 2>/dev/null | awk '{print $0/1024/1024/1024 " GB"}' || \
  grep MemTotal /proc/meminfo | awk '{print $2/1024/1024 " GB"}'

# Detect Docker allocated resources
docker info --format 'Memory: {{.MemTotal}}, CPUs: {{.NCPU}}'

# Detect available disk space
docker system df
```

**Adapt configurations based on detection:**

| Detected Docker Memory | Profile | Build Memory | Container Limits |
|-----------------------|---------|--------------|------------------|
| < 4GB | Constrained | 1GB | 256Mi |
| 4-8GB | Minimal | 2GB | 512Mi |
| 8-12GB | Standard | 4GB | 1Gi |
| > 12GB | Extended | 8GB | 2Gi |

### Agent Behavior

1. **Detect** Docker resources before generating compose.yaml
2. **Adapt** resource limits to available memory
3. **Warn** if build may fail due to insufficient resources
4. **Calculate** safe limits: `docker_memory * 0.6 / container_count`

### Adaptive Compose Templates

**Constrained (< 4GB Docker):**
```yaml
services:
