# Docker Hub Deployment Guide

This guide will help you publish the StreamFlow Docker image to Docker Hub so users can easily deploy it.

## Prerequisites

1. Docker Hub account (create one at https://hub.docker.com)
2. Docker installed and running locally

## Step 1: Login to Docker Hub

```bash
docker login
```

Enter your Docker Hub username and password when prompted.

## Step 2: Build the Docker Image

Build the image with your Docker Hub username:

```bash
docker build -t aiulian25/streamflow:latest .
```

You can also create version tags:

```bash
docker build -t aiulian25/streamflow:latest -t aiulian25/streamflow:v1.0.0 .
```

## Step 3: Push to Docker Hub

Push the image to Docker Hub:

```bash
docker push aiulian25/streamflow:latest
```

If you created version tags, push them too:

```bash
docker push aiulian25/streamflow:v1.0.0
```

## Step 4: Verify on Docker Hub

Visit https://hub.docker.com/r/aiulian25/streamflow to verify your image is published.

## Automated Build (Optional)

You can set up GitHub Actions to automatically build and push images:

### Create `.github/workflows/docker-publish.yml`:

```yaml
name: Build and Push Docker Image

on:
  push:
    branches:
      - main
    tags:
      - 'v*'
  pull_request:
    branches:
      - main

env:
  DOCKER_HUB_USERNAME: aiulian25
  IMAGE_NAME: streamflow

jobs:
  build-and-push:
    runs-on: ubuntu-latest
    permissions:
      contents: read
      packages: write

    steps:
      - name: Checkout repository
        uses: actions/checkout@v4

      - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v3

      - name: Log in to Docker Hub
        uses: docker/login-action@v3
        with:
          username: ${{ secrets.DOCKER_HUB_USERNAME }}
          password: ${{ secrets.DOCKER_HUB_TOKEN }}

      - name: Extract metadata
        id: meta
        uses: docker/metadata-action@v5
        with:
          images: ${{ env.DOCKER_HUB_USERNAME }}/${{ env.IMAGE_NAME }}
          tags: |
            type=ref,event=branch
            type=ref,event=pr
            type=semver,pattern={{version}}
            type=semver,pattern={{major}}.{{minor}}
            type=raw,value=latest,enable={{is_default_branch}}

      - name: Build and push Docker image
        uses: docker/build-push-action@v5
        with:
          context: .
          push: ${{ github.event_name != 'pull_request' }}
          tags: ${{ steps.meta.outputs.tags }}
          labels: ${{ steps.meta.outputs.labels }}
          cache-from: type=gha
          cache-to: type=gha,mode=max

```

### Add Docker Hub Secrets to GitHub:

1. Go to your repository: https://github.com/aiulian25/streamflow
2. Navigate to **Settings** → **Secrets and variables** → **Actions**
3. Add the following secrets:
   - `DOCKER_HUB_USERNAME`: Your Docker Hub username (aiulian25)
   - `DOCKER_HUB_TOKEN`: Create a token at https://hub.docker.com/settings/security

## Usage for End Users

After publishing, users can simply run:

```bash
# Download the docker-compose.yml
wget https://raw.githubusercontent.com/aiulian25/streamflow/main/docker-compose.yml

# Create environment file (optional)
cat > .env <<EOF
JWT_SECRET=$(openssl rand -base64 32)
SESSION_SECRET=$(openssl rand -base64 32)
ENABLE_GPU=false
EOF

# Start the application
docker compose up -d
```

## Multi-Architecture Support (Optional)

To support multiple architectures (amd64, arm64):

```bash
# Create and use a new builder
docker buildx create --name mybuilder --use
docker buildx inspect --bootstrap

# Build and push for multiple platforms
docker buildx build --platform linux/amd64,linux/arm64 \
  -t aiulian25/streamflow:latest \
  -t aiulian25/streamflow:v1.0.0 \
  --push .
```

## Quick Commands Reference

```bash
# Build image
docker build -t aiulian25/streamflow:latest .

# Push image
docker push aiulian25/streamflow:latest

# Test locally
docker run -d -p 12345:12345 -p 9000:9000 aiulian25/streamflow:latest

# Check running container
docker ps

# View logs
docker logs streamflow
```

## Image Size Optimization

The current Dockerfile is already optimized with:
- Multi-stage builds
- Minimal base image (node:20-slim)
- Cleaned apt caches
- Only production dependencies

Current estimated size: ~1.5GB (due to ffmpeg, streamlink, yt-dlp requirements)

## Updating the Image

When you make changes:

1. Build with new version tag:
   ```bash
   docker build -t aiulian25/streamflow:v1.0.1 -t aiulian25/streamflow:latest .
   ```

2. Push both tags:
   ```bash
   docker push aiulian25/streamflow:v1.0.1
   docker push aiulian25/streamflow:latest
   ```

3. Users can update by pulling the latest:
   ```bash
   docker compose pull
   docker compose up -d
   ```
