# ht-docker-tools # 🐳 ht-docker-tools
Docker images for various tools (MongoDB, MinIO, ClickHouse, Caddy, Redis) enhanced with Deno runtime support. **Production-ready Docker images for MongoDB, MinIO, ClickHouse, Caddy, and Redis — supercharged with Deno and Node.js runtimes.**
## Available Images These images let you run your favorite infrastructure tools alongside modern JavaScript/TypeScript tooling. Whether you need to script database migrations, automate object storage, or run custom health checks — you're covered.

## 🎯 Why ht-docker-tools?
- **Scripting-Ready**: Every image includes Deno for running TypeScript scripts directly in containers
- **Two Flavors**: Choose official base images (minimal changes) or Alpine images (lightweight with full Node.js/NVM support)
- **Multi-Arch**: Full support for `linux/amd64` and `linux/arm64` (Apple Silicon friendly)
- **CI/CD Optimized**: NVM works out of the box in GitHub Actions, GitLab CI, and any `docker exec bash -c` workflow

## Quick Start ---
### Using Official Base Images ## 🚀 Quick Start
### Pull from Registry
```bash ```bash
# MongoDB with Deno scripting # Official base images
docker run -d --name mongo ht-docker-tools:mongodb docker pull code.foss.global/host.today/ht-docker-tools:mongodb
docker pull code.foss.global/host.today/ht-docker-tools:redis
# Execute Deno script inside container # Alpine images (recommended for most use cases)
docker exec mongo deno run --allow-net script.ts docker pull code.foss.global/host.today/ht-docker-tools:mongodb-alpine
docker pull code.foss.global/host.today/ht-docker-tools:redis-alpine
# Redis with Deno
docker run -d --name redis ht-docker-tools:redis
``` ```
### Using Alpine Images ### Run with Deno Scripts
```bash ```bash
# MongoDB Alpine with Node.js and Deno # Start MongoDB
docker run -d --name mongo-alpine ht-docker-tools:mongodb-alpine docker run -d --name mongo code.foss.global/host.today/ht-docker-tools:mongodb
# Use Node.js # Execute a Deno script inside the container
docker exec mongo-alpine bash -c "node --version" docker exec mongo deno run --allow-net --allow-read script.ts
# Use Deno
docker exec mongo-alpine bash -c "deno --version"
# Switch Node versions with NVM
docker exec mongo-alpine bash -c "nvm install 18 && nvm use 18 && node --version"
``` ```
## Features ### Use Node.js with NVM (Alpine Images)
### Official Base Images ```bash
- Extend official Docker images (MongoDB, MinIO, ClickHouse, Caddy, Redis) # Start Redis Alpine
- Add Deno runtime for scripting and automation docker run -d --name redis code.foss.global/host.today/ht-docker-tools:redis-alpine
- Preserve original image entrypoints and configurations
- Ideal for production use with existing configurations
### Alpine Images # Check Node version
- Lightweight Alpine-based (significantly smaller than official images) docker exec redis bash -c "node --version"
- Full NVM support for Node.js version switching # v20.18.2
- Node.js LTS (20.18.2) pre-installed
- Deno runtime included
- Multi-architecture support (amd64/arm64)
- Ideal for CI/CD and development environments
## Docker Compose Example # Switch Node versions on the fly
docker exec redis bash -c "nvm install 18 && nvm use 18 && node --version"
# v18.x.x
```

## 🛠️ NVM in Docker — It Just Works™
NVM is notoriously tricky in Docker because it's a bash function, not a binary. These Alpine images solve this with a smart entrypoint that handles three contexts:
| Context | How It Works |
|---------|--------------|
| **Dockerfile RUN** | Custom shell wrapper loads NVM before each command |
| **CI/CD `bash -c`** | Entrypoint detects and injects bashrc sourcing |
| **Interactive shells** | Standard bashrc initialization |
```bash
# Works in CI/CD pipelines
docker exec mycontainer bash -c "nvm use 18 && npm install && npm test"
# Works in Dockerfiles
FROM code.foss.global/host.today/ht-docker-tools:mongodb-alpine
RUN nvm install 18 && npm install -g typescript
```

## NVM Usage (Alpine Images) ---
Alpine images include NVM for Node.js version management: ## 📋 Bundled Versions
```bash | Component | Version |
# Check NVM version |-----------|---------|
docker run --rm ht-docker-tools:redis-alpine bash -c "nvm --version" | NVM | v0.40.1 |
| Node.js LTS | v20.18.2 |
| Deno | Latest (from Alpine edge/community) |
# Install specific Node.js version Alpine images use `unofficial-builds.nodejs.org` for musl-compatible Node.js binaries.
docker run --rm ht-docker-tools:redis-alpine bash -c "nvm install 18 && node --version"
# Use in Dockerfile ---
FROM code.foss.global/host.today/ht-docker-tools:mongodb-alpine
RUN nvm install 18 && nvm use 18 && npm install -g typescript
```
## Registry ## 🎯 Use Cases
Images are available at: - **Database Migrations**: Run TypeScript migration scripts directly in your DB container
- `code.foss.global/host.today/ht-docker-tools` - **Health Checks**: Write sophisticated health probes in Deno
- **Scripted Backups**: Automate backup tasks with Node.js scripts
- **CI/CD Integration**: Execute tests that need both database and runtime
- **Local Development**: Single container with everything you need
