# phCD

Continuous Deployment for PHC projects.

## Development

```bash
# First install the dependencies
$ pnpm install

# Run the local server
$ pnpm dev

# Build all
$ pnpm build
```

## Production Setup

Run the following command to bootstrap a **phCD** instance. As this service doesn't have auth for now, it's strongly recommended to publish only on a local ip like `127.0.0.1` and then access directly or via an ssh tunnel (something like `ssh -L 8080:127.0.0.1:8080 server`).

```bash
# Clone this repo
git clone https://git.phc.dm.unipi.it/phc/phcd

# Create config files and data folder
mkdir data.local
cp .env.sample .env
echo 'deploys: []' > config.yaml

# Built docker image
docker built . -t phcd

# Start container
docker run -d \
  --name phcd \
  --restart unless-stopped \
  -p 127.0.0.1:8080:4321 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v ./data.local:/app/data.local \
  -v ./.env:/app/.env \
  -v ./config.yaml:/app/config.yaml \
  phcd
```

### Updating

Just pull changes and update the docker image, then use the command from before to restart the main container.

```bash
git pull
docker stop phcd
docker rm phcd
docker built . -t phcd
```

### TODO: Self-Updating

It should be possible to deploy itself using a git+dockerfile deployment. For now this is more complicated as this requires to stop itself and spawn a new docker container of itself.

~~**Idea 1.** Create another `self-update.Dockerfile` that also gets mounted `/var/run/docker.sock`, this new container will then run the previous commands~~ [...] if we want the volume to be a folder this cannot be easily done

## Architecture

Everything is stored in the `config.yaml` file. This file contains a list of projects to deploy and the configuration for each one.

```yaml
deploys:
  - name: project1
    url: https://github.com/username/project1
    ref: 
      type: branch
      value: main
    type: dockerfile
    options:
      ports: 
        - 80:8080
      volumes: 
        - /var/www/html:/var/www/html
  - name: project2
    url: ssh://example.org/username/project2.git
    ref:
      type: commit
      value: '1234567'
    type: docker-compose
    options:
      path: ./docker-compose.yml # already the default
  - name: project3
    url: https://github.com/username/project3
    type: shell
    options:
      path: ./deploy.sh # already the default
```
