This project runs [Quartz](https://quartz.jzhao.xyz/) v4.4.0, a fast, batteries-included static site generator, inside a Docker container. It transforms Markdown content into a fully functional website.

While Quartz provides [Docker support](https://quartz.jzhao.xyz/features/Docker-Support), it is not as self contained as this project.

There is no support for SSL or any other features that are not directly related to building the site. I run everything behind traefik, so I don't need it.

## 🐳 Docker Compose Setup

Create a data directory

```bash
mkdir -p /srv/quartz
```

```yaml title="docker-compose.yml"
services:
  quartz-wiki:
    container_name: quartz-wiki
    image: code.modernleft.org/gravityfargo/quartz-docker:dev
    ports:
      - 80:80
    environment:
      USER_ID: 1000
      GROUP_ID: 1001
      SERVER_NAME: "docs.modernleft.org"
      ENABLE_CRON: "true"
      BUILD_SCHEDULE: "*/30 * * * *"
      CONTENT_REPO: "https://code.modernleft.org/gravityfargo/modernleft-docs.git"
    volumes:
      - /srv/quartz:/quartz
```

**First Run**

```bash
docker-compose up -d
docker stop quartz-wiki
```

On first run, the container will download the necessary dependencies, build the site, and download the content repository.

After that, you can configure whatever you would like in `/srv/quartz/src` using the stock options found in the quartz [documentation](https://quartz.jzhao.xyz/configuration)
Bare minimum should be `baseUrl` and `pageTitle`.

🥳 Done! 🎉

> [!NOTE] Cloudflare
> I've found that the cron schedule will eventually start having fatal git errors. Disabling Cloudflare fixed this. I am moving away from their services after their many controversies. Do with that what you will.

## Manually Building the Site

If you don't use the cron job, and don't feel like restarting the container, you can build the site manually.

```bash
docker exec -it quartz-wiki bash
#
cd /quartz/content/ && git restore . && git pull
cd /quartz/src/ && npx quartz build
```

## ⚙️ Configuration

**cron**

This is the an equivalent command to the cron job.

```bash
cd /quartz/content
git restore .
git pull
cd /quartz/src &
npx quartz build
echo 'Content Updated.'
```

Setting `ENABLE_CRON` to `true` and defining `BUILD_SCHEDULE` performs these actions.
If you need help configuring [Crontab.guru - The cron schedule expression generator](https://crontab.guru/) is a useful tool for that

Example:

```yaml
environment:
  ENABLE_CRON: "true"
  BUILD_SCHEDULE: "*/1 * * * *" # Runs every minute
```
