[quartz-docker image](https://code.modernleft.org/gravityfargo/-/packages/container/quartz-docker/v4.4.0)
```bash
docker pull code.modernleft.org/gravityfargo/quartz-docker:v4.4.0
```
This project runs **Quartz 4.4.0**, 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.
## 🐳 Docker Compose Setup
Create a data directory and pull your existing content
```bash
# create directories
mkdir -p /srv/quartz/config
cd /srv/quartz
# clone your content
git clone https://code.modernleft.org/gravityfargo/modernleft-docs.git content
```
### Compose File
Create a `docker-compose.yml` file:
![[docker-compose]]
### First Run
```bash
docker-compose up -d
docker stop quartz-wiki
```
On first run, the container will download the necessary dependencies and build the site.
In `/srv/quartz/config/config.json`, you need to change the `baseUrl` to your domain.
## ⚙️ Configuration
### Optional `node_modules` volume
To keep the image small, `node_modules` are not included. When the container is run, they are downloaded to `/usr/share/nginx/html/node_modules`. Mounting this as a volume ensures they persist between container runs, reducing setup time.
### cron
This is the command run by cron
```bash
cd /usr/share/nginx/html/content && \
git pull >/dev/null 2>&1 && \
cd /usr/share/nginx/html && \
npx quartz build >/dev/null 2>&1
```
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
```
### Environment Variables
See a list of all environment variables [here](#environment-variables).
| Variable | Description | Default Value |
| -------------------- | ----------------------------------------------------- | ----------------------------- |
| `NGINX_PORT` | Port for the Nginx server | `80` |
| `SERVER_NAME` | NGINX server name | `quartz.zhao.xyz` |
| `ENABLE_CRON` | Enables scheduled builds (`true` or `false`) | `false` |
| `BUILD_SCHEDULE` | Cron expression for scheduling site builds | `"*/10 * * * *"` every 10 min |
| `QUARTZ_CONFIG_PATH` | Path to the Quartz configuration file | `/config/quartz.json` |
| `USER_ID` | UID that` /content` and` /config` will be chown'd to. | `1000` |
| `GROUP_ID` | GID that` /content` and` /config` will be chown'd to. | `1000` |
You shouldn't need to change `QUARTZ_CONFIG_PATH`
