# Changelog # Changelog
## 2025-10-26 - 5.0.148 - feat(alpine)
Major restructuring: Multi-architecture Alpine Docker images with modern runtime support
**Breaking Changes:**
- Removed `Dockerfile_alpine` (replaced by `Dockerfile_alpine_node`)
- Removed `Dockerfile_iot` (no longer needed with multi-arch approach)
- Tag naming simplified: `:alpine-node` instead of `:alpine-x64-node` and `:alpine-arm64-node`
**New Multi-Architecture Alpine Images (3 variants):**
All images support both amd64 and arm64 architectures natively:
- `Dockerfile_alpine_node` → `:alpine-node` - Alpine with Node.js LTS + NVM + pnpm
- `Dockerfile_alpine_deno` → `:alpine-deno` - Alpine with Node.js LTS + NVM + Deno
- `Dockerfile_alpine_bun` → `:alpine-bun` - Alpine with Node.js LTS + NVM + Bun
**Technical Improvements:**
- **Multi-architecture support**: Single Docker image works natively on both x64 (AMD64) and ARM64 (Apple Silicon, ARM servers)
- **docker buildx integration**: Build script uses buildx for proper multi-platform image creation
- **Native performance**: No emulation needed - images run at full native speed on both architectures
- **Automatic platform selection**: Docker automatically pulls the correct architecture variant
- Full NVM support in all Alpine images (v0.40.1)
- Node.js musl builds from unofficial-builds.nodejs.org for Alpine compatibility
- Significantly smaller image sizes (200-300MB vs 800MB+ Ubuntu)
- All images include NVM for flexible version management
- Reused wrapper scripts from Ubuntu base for consistency
- Added Bun and Deno runtime support
**Build & Test Infrastructure:**
- Updated `build-alpine-images.sh` to use `docker buildx` with native platform builds for local testing
- Updated `test-alpine-images.sh` to test 3 multi-arch images instead of 9 architecture-specific images
- Simplified test suite focuses on runtime functionality and NVM version switching
**Documentation:**
- Updated README with multi-architecture approach explanation
- Simplified examples using new tag names (`:alpine-node`, `:alpine-deno`, `:alpine-bun`)
- Added cross-platform development examples
- Documented native performance benefits
- Removed architecture-specific instructions (no longer needed)
## 2025-10-26 - 5.0.147 - feat(nvm) ## 2025-10-26 - 5.0.147 - feat(nvm)

# ht-docker-node
docker image with nodejs and shipzone.io support
## Install
To get started with `ht-docker-node`, you need to have Docker installed on your machine. You can then pull the desired flavor of the Docker image from the relevant Docker registry.
Example:
```bash
docker pull registry.gitlab.com/hosttoday/ht-docker-node:latest
```
## Usage
`ht-docker-node` offers a variety of Docker image flavors to suit different needs. Below, we'll guide you through different use cases and configurations using these Docker images.
### Flavour Overview
- **:lts** - Node LTS version, equivalent to :latest
- **:stable** - Node stable version
- **:npmci** - `npmci` preinstalled
- **:npmts** - `npmci` + `npmts` preinstalled
- **:npmpage** - `npmci` + `npmts` + `npmpage` preinstalled
- **:mongo** - `npmci` + `npmts` + `mongo`
### Basic Usage
To start a container with the `lts` flavour, you can use the following command:
```bash
docker run -it --name your_container_name registry.gitlab.com/hosttoday/ht-docker-node:lts
```
### Using `npmci`
The `:npmci` flavour includes `npmci`, a utility for managing Node.js versions and npm installations. Here's an example of how you can use it:
```Dockerfile
FROM registry.gitlab.com/hosttoday/ht-docker-node:npmci
RUN npmci install 14.17.0
```
In this example, `npmci` installs Node.js version `14.17.0` and sets it as the default.
### Using NVM in Dockerfiles
The base image includes **nvm (Node Version Manager)** for flexible Node.js version management. Use nvm commands directly in Dockerfile RUN statements without any sourcing required:
```dockerfile
FROM registry.gitlab.com/hosttoday/ht-docker-node:latest
# Use nvm directly - no sourcing needed
RUN nvm install 18.20.0
RUN nvm use 18 && npm install
# Or chain commands
RUN nvm install 19.0.0 && nvm use 19 && npm ci
```
**Important**: Each RUN command is a separate shell. To persist version changes across RUN commands, set a new default:
```dockerfile
RUN nvm install 18.20.0 && nvm alias default 18
# Subsequent RUN commands will use v18 by default
```
### Using NVM in CI/CD Workflows
NVM is automatically available in CI/CD workflow scripts when using `bash -c`:
```yaml
jobs:
build:
runs-on: ubuntu-latest
container:
image: registry.gitlab.com/hosttoday/ht-docker-node:latest
steps:
- name: Use specific Node version
run: |
nvm install 18.20.0
nvm use 18
npm install
npm test
- name: Test multiple versions
run: |
for version in 16 18 20; do
nvm install $version
nvm use $version
npm test
done
```
### NVM vs npmci
Both tools are available in the image:
- **nvm**: Standard Node version manager, works in Dockerfiles and CI/CD workflows
- **npmci**: CI-focused wrapper with additional shipzone.io features
Choose based on your preference - they work together seamlessly.
### Custom Dockerfile with `npmci` and your Node.js App
You can create a custom Dockerfile for your Node.js application using the `:npmci` flavour:
```Dockerfile
# Use the ht-docker-node image with npmci
FROM registry.gitlab.com/hosttoday/ht-docker-node:npmci
# Install a specific Node.js version
RUN npmci install 14.17.0
# Create app directory
WORKDIR /usr/src/app
# Copy package.json and package-lock.json
COPY package*.json ./
# Install app dependencies
RUN npm install
# Bundle app source
COPY . .
# Expose port
EXPOSE 8080
# Start the application
CMD ["node", "index.js"]
```
To build the Docker image:
```bash
docker build -t your_app_name .
```
To run the container:
```bash
docker run -p 8080:8080 --name your_container_name your_app_name
```
### Multi-Stage Builds for Production
For a leaner production image, you can use multi-stage builds. Here’s an example:
```Dockerfile
# Stage 1: Build
FROM registry.gitlab.com/hosttoday/ht-docker-node:npmci as build
RUN npmci install 14.17.0
WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install
COPY . .
RUN npm run build
# Stage 2: Production
FROM registry.gitlab.com/hosttoday/ht-docker-node:lts
WORKDIR /usr/src/app
COPY --from=build /usr/src/app/dist ./
EXPOSE 8080
CMD ["node", "index.js"]
```
### Using with MongoDB (`:mongo`)
The `:mongo` flavour contains a MongoDB installation alongside Node.js. Here’s how you can utilize it in your Dockerfile:
```Dockerfile
FROM registry.gitlab.com/hosttoday/ht-docker-node:mongo
# Setup mongo and node environment:
RUN npm install -g mongodb
# Working directory
WORKDIR /usr/src/app
# Copy MongoDB config
COPY mongod.conf /etc/mongod.conf
# Start MongoDB service
CMD ["mongod", "--config", "/etc/mongod.conf"] && node index.js
```
### Using `npmts` and `npmpage`
The `:npmts` and `:npmpage` flavours are useful for projects that use TypeScript or require page generation.
Here’s an example on how to work with `:npmts`:
```Dockerfile
FROM registry.gitlab.com/hosttoday/ht-docker-node:npmts
# Install necessary TypeScript packages
RUN npm install -g typescript
# Working directory
WORKDIR /usr/src/app
# Copy package.json and package-lock.json
COPY package*.json ./
# Install dependencies
RUN npm install
# Copy the rest of your files
COPY . .
# Compile TypeScript
RUN npm run build
# Expose port and start the server
EXPOSE 3000
CMD ["npm", "start"]
```
### Comprehensive Use Case Example
The following example covers multiple aspects including environment variables, volume mounting, and networking.
#### Dockerfile:
```Dockerfile
FROM registry.gitlab.com/hosttoday/ht-docker-node:npmci
# Set environment variables
ENV NODE_ENV=production
ENV PORT=3000
# Install desired Node.js version
RUN npmci install 16.0.0
# Create app directory
WORKDIR /usr/src/app
# Copy package.json and package-lock.json
COPY package*.json ./
# Install app dependencies
RUN npm ci
# Bundle app source
COPY . .
# Compile TypeScript
RUN npm run build
# Expose app port
EXPOSE 3000
# Start the application
CMD ["npm", "start"]
```
#### Docker-Compose Configuration
If using Docker-Compose, create a `docker-compose.yml` file:
```yaml
version: '3.8'
services:
app:
image: your_app_name
build:
context: .
dockerfile: Dockerfile
ports:
- '3000:3000'
environment:
- NODE_ENV=production
volumes:
- .:/usr/src/app
- /usr/src/app/node_modules
networks:
- app-network
networks:
app-network:
driver: bridge
```
#### Running with Docker and Docker-Compose
To build the image:
```bash
docker-compose build
```
To run the services:
```bash
docker-compose up
```
#### Accessing the Container
```bash
docker exec -it your_container_name /bin/sh
```
### Conclusion
`ht-docker-node` offers a flexible, multifaceted solution for deploying Node.js applications in Docker containers. By leveraging its different flavours, you can efficiently manage Node.js versions, incorporate MongoDB, and handle TypeScript projects. Whether you are using simple Docker commands or elaborate Docker-Compose configurations, `ht-docker-node` caters to diverse deployment scenarios.
