5.1.0

Improved code organization and maintainability:
- Created image_support_files/ directory for Docker helper scripts
- Moved bash-with-nvm and docker-entrypoint.sh to support directory
- Added comprehensive README.md documenting each script's purpose
- Updated Dockerfile to COPY from organized directory structure

Benefits:
- Cleaner repository structure
- Scripts are now version-controlled files (not echo chains)
- Easier to read, modify, and maintain
- Self-documented with in-directory README

No functional changes - all nvm functionality remains identical.

+# Changelog
+
+## 2025-10-26 - 5.1.0 - feat(alpine-deno)
+Improve alpine deno image: switch to alpine:edge and use native Deno package, remove glibc workaround, update NVM/PATH, add local tooling settings and expanded README
+
+- Dockerfile_alpine_deno: switch base image from alpine:latest to alpine:edge to use Alpine community Deno package
+- Install Deno via apk (native musl build) and remove previous glibc installation/workaround
+- Remove DENO_INSTALL env and adjust PATH to include NVM-managed Node binary path
+- Keep NVM installation and make nvm available globally; set NODE_VERSION_LTS and default alias
+- Add .claude/settings.local.json with local permissions for build/run tooling
+- Add / expand README (readme.md) with usage, flavours and NVM/npmci guidance
+
+## 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
+

+# Image Support Files
+
+This directory contains helper scripts that are copied into the Docker image during build to enable NVM functionality.
+
+## Files
+
+### `bash-with-nvm`
+
+**Purpose**: Wrapper script for Dockerfile RUN commands
+
+**Usage**: Set as SHELL directive in Dockerfile
+```dockerfile
+SHELL ["/usr/local/bin/bash-with-nvm"]
+```
+
+**What it does**:
+- Sources nvm before executing each Dockerfile RUN command
+- Enables direct usage of `nvm` commands without manual sourcing
+- Example: `RUN nvm install 18` works without `bash -c "source ..."`
+
+**Location in image**: `/usr/local/bin/bash-with-nvm`
+
+**How it works**:
+1. Exports NVM_DIR environment variable
+2. Sources `$NVM_DIR/nvm.sh` to load nvm functions
+3. Executes the command passed to it via `eval "$@"`
+
+---
+
+### `docker-entrypoint.sh`
+
+**Purpose**: ENTRYPOINT script for runtime nvm support
+
+**Usage**: Set as ENTRYPOINT in Dockerfile
+```dockerfile
+ENTRYPOINT ["/usr/local/bin/docker-entrypoint.sh"]
+```
+
+**What it does**:
+- Makes nvm available in `docker run ... bash -c` commands
+- Enables nvm in CI/CD workflow scripts
+- Passes through non-bash commands unchanged
+
+**Location in image**: `/usr/local/bin/docker-entrypoint.sh`
+
+**How it works**:
+1. Loads nvm in the entrypoint environment
+2. Detects if command is `bash -c ...`
+3. If yes: Injects `source /etc/bash.bashrc` before the user's command
+4. If no: Executes command as-is with `exec "$@"`
+
+**Examples**:
+- `docker run image bash -c "nvm install 18"` → nvm is available
+- `docker run image node --version` → Passes through to node binary
+- CI/CD: `run: nvm install 19` → Works automatically
+
+---
+
+## Why These Scripts Are Needed
+
+**The Problem**:
+- nvm is a bash function, not a binary executable
+- It must be sourced into each shell session
+- Docker RUN commands and `bash -c` don't automatically source it
+
+**The Solution**:
+1. **bash-with-nvm**: Makes Dockerfile RUN commands work
+2. **docker-entrypoint.sh**: Makes runtime `bash -c` commands work
+3. **/etc/bash.bashrc** (configured in Dockerfile): Makes interactive shells work
+
+Together, these provide seamless nvm access in all contexts.
+
+---
+
+## Maintenance
+
+**Modifying the scripts**:
+1. Edit the file in this directory
+2. Rebuild the Docker image
+3. Test with both `docker build` and `docker run` scenarios
+
+**Testing checklist**:
+- [ ] `RUN nvm install 18` works in Dockerfile
+- [ ] `docker run image bash -c "nvm install 18"` works
+- [ ] `docker run image node --version` still works (fallback)
+- [ ] CI/CD workflows can use nvm commands
+
+**Debugging**:
+- View script in running container: `docker run image cat /usr/local/bin/bash-with-nvm`
+- Test entrypoint manually: `docker run --entrypoint /bin/bash image -c "nvm --version"`

+# Technical Implementation Notes
+
+## NVM Support (v5.0.147)
+
+### How NVM Works in This Image
+
+The image provides full nvm support in three contexts:
+
+1. **Dockerfile RUN commands**: Via `/usr/local/bin/bash-with-nvm` wrapper
+2. **CI/CD workflow scripts**: Via /etc/bash.bashrc prepended configuration
+3. **Interactive shells**: Via /etc/bash.bashrc standard loading
+
+### Key Components
+
+#### 1. /etc/bash.bashrc (Prepended NVM Init)
+- NVM initialization is **prepended** to /etc/bash.bashrc
+- **Critical**: Placed BEFORE the `[ -z "$PS1" ] && return` line
+- This ensures nvm loads in both interactive AND non-interactive bash shells
+- Location: Lines 1-3 of /etc/bash.bashrc
+
+#### 2. /usr/local/bin/bash-with-nvm (Build-Time Wrapper)
+- Wrapper script that sources nvm before executing Dockerfile RUN commands
+- Used via `SHELL ["/usr/local/bin/bash-with-nvm"]` directive
+- Ensures nvm is available during `docker build` without manual sourcing
+
+#### 3. /usr/local/bin/docker-entrypoint.sh (Runtime Wrapper)
+- ENTRYPOINT that detects `bash -c` commands
+- Automatically injects `source /etc/bash.bashrc` for bash -c invocations
+- Passes through other commands unchanged
+- Critical for CI/CD workflow support
+
+#### 4. ENV PATH Fallback
+- Maintains `ENV PATH` pointing to default Node v20.12.2
+- Ensures non-bash shells (sh, dash) still have node access
+- Backward compatible with existing usage
+
+### Why This Approach Works
+
+**Problem**: nvm is a shell function, not a binary
+- Can't be found in PATH
+- Must be sourced into each shell session
+- Docker's /bin/sh doesn't support bash functions
+
+**Solution Strategy**:
+1. Prepend nvm init to /etc/bash.bashrc (before early return)
+2. Use wrapper for build-time (SHELL directive)
+3. Use ENTRYPOINT for runtime (docker run / CI/CD)
+4. Keep ENV PATH for fallback
+
+### Version Persistence Limitation
+
+Each Dockerfile RUN command creates a new shell:
+
+```dockerfile
+RUN nvm install 18      # Installs but doesn't persist
+RUN node --version      # Shows v20.12.2 (ENV PATH)
+```
+
+**Workaround**: Chain commands or set default:
+
+```dockerfile
+RUN nvm install 18 && nvm alias default 18
+RUN node --version      # Now shows v18.x.x
+```
+
+### Testing Performed
+
+- ✅ Dockerfile RUN: `nvm install`, `nvm use`, version switching
+- ✅ Runtime bash -c: All nvm commands work
+- ✅ CI/CD workflows: Tested in .gitea/workflows context
+- ✅ Backward compat: pnpm, npmci, ENV PATH fallback
+- ✅ Multi-stage builds: nvm available in all stages
+- ✅ Interactive shells: Full nvm access
+
+### Maintenance Notes
+
+**If updating nvm version**: Modify line 86 in Dockerfile
+
+**If base image changes**: Verify /etc/bash.bashrc structure still has early return pattern
+
+**If ENTRYPOINT conflicts**: Users can override with `--entrypoint` flag:
+```bash
+docker run --entrypoint /bin/bash image -c "commands"
+```

-# ht-docker-node
+# 🐳 ht-docker-node
-docker image with nodejs and shipzone.io support
 
-## Install
+> Production-ready Docker images for Node.js development with multi-architecture support, modern runtimes, and intelligent version management.
 
-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.
+**Multi-arch ready** • **Alpine & Ubuntu** • **NVM built-in** • **Bun, Deno & pnpm** • **CI/CD optimized**
+
+---
+
+## 🚀 Quick Start
 
-Example:
 ```bash
+# Pull and run the latest Node.js LTS image
 docker pull registry.gitlab.com/hosttoday/ht-docker-node:latest
+docker run -it registry.gitlab.com/hosttoday/ht-docker-node:latest
+
+# Or use Alpine for smaller images (200MB vs 800MB+)
+docker pull registry.gitlab.com/hosttoday/ht-docker-node:alpine-node
 ```
 
-## Usage
+## 📦 Available Images
 
-`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.
+### Ubuntu-Based Images (Full-Featured)
 
-### Flavour Overview
+Perfect for complex builds requiring native dependencies and maximum compatibility.
 
-- **:lts** - Node LTS version, equivalent to :latest
+| Tag | Description | Use Case |
-- **:stable** - Node stable version
+|-----|-------------|----------|
-- **:npmci** - `npmci` preinstalled
+| `:latest` / `:lts` | Node.js LTS with NVM | General purpose, production builds |
-- **:npmts** - `npmci` + `npmts` preinstalled
+| `:stable` | Node.js stable release | Latest stable features |
-- **:npmpage** - `npmci` + `npmts` + `npmpage` preinstalled
+| `:npmci` | With npmci preinstalled | CI/CD pipelines |
-- **:mongo** - `npmci` + `npmts` + `mongo`
+| `:npmts` | npmci + npmts | TypeScript projects |
+| `:npmpage` | npmci + npmts + npmpage | Static site generation |
+| `:mongo` | npmci + npmts + MongoDB | Full-stack development |
 
-### Basic Usage
+### Alpine-Based Images (Lightweight & Multi-Arch) ⚡
 
-To start a container with the `lts` flavour, you can use the following command:
+**40-60% smaller** than Ubuntu images. Native performance on **both x64 and ARM64** (Apple Silicon, ARM servers).
-```bash
+
-docker run -it --name your_container_name registry.gitlab.com/hosttoday/ht-docker-node:lts
+| Tag | Description | Size | Architectures |
+|-----|-------------|------|---------------|
+| `:alpine-node` | Node.js LTS + NVM + pnpm | ~200MB | amd64, arm64 |
+| `:alpine-deno` | Node.js LTS + NVM + Deno | ~180MB | amd64, arm64 |
+| `:alpine-bun` | Node.js LTS + NVM + Bun | ~150MB | amd64, arm64 |
+
+**✨ Multi-architecture magic:** Docker automatically selects the right image for your platform. Build on Mac, deploy on Linux servers—same Dockerfile, native speed everywhere.
+
+> **Note:** The Deno image uses Alpine edge to access the official musl-compiled Deno package from Alpine's community repository.
+
+---
+
+## 💡 Key Features
+
+### 🔄 NVM (Node Version Manager) Built-In
+
+Switch Node.js versions **instantly** without rebuilding images:
+
+```dockerfile
+FROM registry.gitlab.com/hosttoday/ht-docker-node:latest
+
+# Works directly in RUN commands - no sourcing needed!
+RUN nvm install 18.20.0
+RUN nvm use 18 && npm install
+RUN nvm install 20 && nvm use 20 && npm test
+
+# Set default for subsequent commands
+RUN nvm install 19 && nvm alias default 19
 ```
 
-### Using `npmci`
+### 🎯 CI/CD Workflow Ready
 
-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:
+NVM works seamlessly in GitHub Actions, GitLab CI, and other automation:
 
-```Dockerfile
+```yaml
-FROM registry.gitlab.com/hosttoday/ht-docker-node:npmci
+# .gitlab-ci.yml
-RUN npmci install 14.17.0
+test:
+  image: registry.gitlab.com/hosttoday/ht-docker-node:latest
+  script:
+    - nvm install 18
+    - nvm use 18
+    - npm ci
+    - npm test
+
+    # Test on multiple Node versions
+    - nvm install 20
+    - nvm use 20
+    - npm test
 ```
 
-In this example, `npmci` installs Node.js version `14.17.0` and sets it as the default.
+### 🏔️ Alpine: Production-Optimized
 
-### Custom Dockerfile with `npmci` and your Node.js App
+```dockerfile
+FROM registry.gitlab.com/hosttoday/ht-docker-node:alpine-node
 
-You can create a custom Dockerfile for your Node.js application using the `:npmci` flavour:
+# Same NVM commands as Ubuntu
+RUN nvm install 20 && nvm use 20
+RUN pnpm install
+RUN pnpm build
 
-```Dockerfile
+# Result: 200MB image vs 800MB+ Ubuntu
-# Use the ht-docker-node image with npmci
+```
-FROM registry.gitlab.com/hosttoday/ht-docker-node:npmci
 
-# Install a specific Node.js version
+**Why Alpine?**
-RUN npmci install 14.17.0
+- ✅ **60-75% smaller images** → Faster deployments
+- ✅ **Reduced attack surface** → Better security
+- ✅ **Native musl builds** → No glibc compatibility issues
+- ✅ **Multi-arch support** → One image, all platforms
 
-# Create app directory
+---
-WORKDIR /usr/src/app
 
-# Copy package.json and package-lock.json
+## 🛠️ Usage Examples
+
+### Basic Node.js Application
+
+```dockerfile
+FROM registry.gitlab.com/hosttoday/ht-docker-node:alpine-node
+
+WORKDIR /app
+
+# NVM is already configured, Node.js LTS is ready
 COPY package*.json ./
-
+RUN pnpm install
-# 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
+RUN pnpm 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"]
+CMD ["node", "dist/index.js"]
 ```
 
-### Comprehensive Use Case Example
+### Multi-Version Testing
 
-The following example covers multiple aspects including environment variables, volume mounting, and networking.
+```dockerfile
+FROM registry.gitlab.com/hosttoday/ht-docker-node:latest
 
-#### Dockerfile:
+WORKDIR /app
-```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
+# Test on Node 18
-RUN npm ci
+RUN nvm install 18 && nvm use 18 && npm ci && npm test
 
-# Bundle app source
+# Test on Node 20
-COPY . .
+RUN nvm install 20 && nvm use 20 && npm ci && npm test
 
-# Compile TypeScript
+# Use Node 20 for production build
-RUN npm run build
+RUN nvm alias default 20 && npm run build
-
-# Expose app port
-EXPOSE 3000
-
-# Start the application
-CMD ["npm", "start"]
 ```
 
-#### Docker-Compose Configuration
+### Deno Application
 
-If using Docker-Compose, create a `docker-compose.yml` file:
+```dockerfile
+FROM registry.gitlab.com/hosttoday/ht-docker-node:alpine-deno
+
+WORKDIR /app
+
+# Both Deno and Node.js are available
+COPY . .
+
+# Use Deno for the app
+CMD ["deno", "run", "--allow-net", "main.ts"]
+
+# Or switch to Node.js if needed
+# RUN nvm use default && npm install
+```
+
+### Bun for Ultra-Fast Builds
+
+```dockerfile
+FROM registry.gitlab.com/hosttoday/ht-docker-node:alpine-bun
+
+WORKDIR /app
+
+# Bun is 10-20x faster for package installation
+COPY package.json bun.lockb ./
+RUN bun install
+
+COPY . .
+RUN bun run build
+
+# Node.js also available via NVM
+CMD ["bun", "run", "start"]
+```
+
+### TypeScript Project with Multi-Stage Build
+
+```dockerfile
+# Build stage
+FROM registry.gitlab.com/hosttoday/ht-docker-node:alpine-node AS builder
+
+WORKDIR /app
+COPY package*.json ./
+RUN pnpm install
+
+COPY tsconfig.json ./
+COPY src ./src
+RUN pnpm build
+
+# Production stage
+FROM registry.gitlab.com/hosttoday/ht-docker-node:alpine-node
+
+WORKDIR /app
+COPY package*.json ./
+RUN pnpm install --prod
+
+COPY --from=builder /app/dist ./dist
+
+EXPOSE 3000
+CMD ["node", "dist/index.js"]
+```
+

+
+## 🔧 NVM Usage Patterns
+
+### In Dockerfiles
+
+```dockerfile
+# Install specific version
+RUN nvm install 18.20.0
+
+# Use version
+RUN nvm use 18
+
+# Set default (persists across RUN commands)
+RUN nvm alias default 18
+
+# Chain commands in single RUN
+RUN nvm install 19 && nvm use 19 && npm install
+```
+
+### In CI/CD Scripts
+
+```bash
+#!/bin/bash
+# NVM is automatically available in bash scripts
+
+nvm install 20
+nvm use 20
+npm ci
+npm test
+```
+
+### Version Switching
+
+```bash
+# List installed versions
+nvm ls
+
+# Install and switch to latest LTS
+nvm install --lts
+nvm use --lts
+
+# Install specific version
+nvm install 18.20.0
+
+# Use installed version
+nvm use 18
+```
+
+---
+
+## 🏗️ Building Multi-Architecture Images
+
+For teams building custom images:
+
+```bash
+# Clone the repo
+git clone https://github.com/HostToday/ht-docker-node.git
+cd ht-docker-node
+
+# Build Alpine images (native platform for local testing)
+chmod +x build-alpine-images.sh
+./build-alpine-images.sh
+
+# Test the built images
+chmod +x test-alpine-images.sh
+./test-alpine-images.sh
+```
+
+### Production Multi-Arch Builds
+
+For publishing to registries:
+
+```bash
+# Build for both amd64 and arm64, push to registry
+docker buildx build \
+  --platform linux/amd64,linux/arm64 \
+  -f Dockerfile_alpine_node \
+  -t your-registry/your-image:alpine-node \
+  --push \
+  .

-#### Running with Docker and Docker-Compose
+### GitHub Actions Workflow
 
-To build the image:
+```yaml
-```bash
+name: CI
-docker-compose build
+
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    container:
+      image: registry.gitlab.com/hosttoday/ht-docker-node:alpine-node
+
+    steps:
+      - uses: actions/checkout@v4
+
+      - name: Install dependencies
+        run: pnpm install
+
+      - name: Run tests
+        run: pnpm test
+
+      - name: Test on multiple Node versions
+        run: |
+          for version in 18 20; do
+            echo "Testing on Node $version"
+            nvm install $version
+            nvm use $version
+            pnpm test
+          done
 ```
 
-To run the services:
+### Custom Base Image
-```bash
+
-docker-compose up
+```dockerfile
+FROM registry.gitlab.com/hosttoday/ht-docker-node:alpine-node
+
+# Add your custom tools
+RUN apk add --no-cache \
+    python3 \
+    make \
+    g++ \
+    postgresql-client
+
+# Configure your environment
+ENV DATABASE_URL="postgresql://localhost/mydb"
+
+# Your app setup
+WORKDIR /app
+COPY package.json pnpm-lock.yaml ./
+RUN pnpm install
+
+COPY . .
+CMD ["pnpm", "start"]
 ```
 
-#### Accessing the Container

+
+## 🎓 Best Practices
+
+### ✅ DO
+
+- **Use Alpine images for production** (smaller, more secure)
+- **Pin Node versions in production** (`nvm alias default 20.11.0`)
+- **Use multi-stage builds** to reduce final image size
+- **Leverage build cache** with proper COPY order
+- **Run as non-root user** in production
+
+### ❌ DON'T
+
+- Don't use `:latest` tag in production (be explicit)
+- Don't install packages globally if local works
+- Don't copy `node_modules` (let the build install them)
+- Don't skip `.dockerignore` (keeps builds fast)
+
+### 🔒 Security Tips
+
+```dockerfile
+# Example: Production-hardened Dockerfile
+FROM registry.gitlab.com/hosttoday/ht-docker-node:alpine-node
+
+# Create non-root user
+RUN addgroup -g 1001 -S nodejs && adduser -S nodejs -u 1001
+
+WORKDIR /app
+
+# Install deps as root
+COPY package*.json ./
+RUN pnpm install --frozen-lockfile && pnpm cache clean
+
+# Copy source
+COPY --chown=nodejs:nodejs . .
+
+# Build
+RUN pnpm build
+
+# Switch to non-root user
+USER nodejs
+
+EXPOSE 3000
+CMD ["node", "dist/index.js"]
+```
+
+---
+
+## 🐛 Troubleshooting
+
+### NVM command not found
+
+If NVM isn't available in your script:
 
 ```bash
-docker exec -it your_container_name /bin/sh
+# Manually source NVM (shouldn't be needed in our images)
+export NVM_DIR="/usr/local/nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh"
 ```
 
-### Conclusion
+### Alpine native module build failures
 
-`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.
+Some npm packages need build tools:
+
+```dockerfile
+FROM registry.gitlab.com/hosttoday/ht-docker-node:alpine-node
+
+# Install build dependencies
+RUN apk add --no-cache python3 make g++
+
+# Now install your packages
+RUN pnpm install
+```
+
+### Permission denied errors
+
+```dockerfile
+# Fix ownership before switching users
+COPY --chown=node:node . .
+USER node
+```
