This currently is pretty minimal and uses:

• apache-2.4.38
• GD library
• Unzip library
• php7.4
• php7.4-opcache
• php7.4-acpu
• php7.4-yaml
• cron
• vim editor

To save the Grav site data to the host file system (so that it persists even after the container has been removed), simply map the container's /var/www/html directory to a named Docker volume or to a directory on the host.

If the mapped directory or named volume is empty, it will be automatically populated with a fresh install of Grav the first time that the container starts. However, once the directory/volume has been populated, the data will persist and will not be overwritten the next time the container starts.

docker build -t grav:latest .

docker run -p 8000:80 grav:latest

Point browser to http://localhost:8000 and create user account...

docker run -d -p 8000:80 --restart always -v grav_data:/var/www/html grav:latest

Running docker-compose up -d with the following docker-compose configuration will automatically build the Grav image (if the Dockerfile is in the same directory as the docker-compose.yml file). Then the Grav container will be started with all of the site data persisted to a named volume (stored in the ./grav directory.

volumes:
  grav-data:
    driver: local
    driver_opts:
      type: none
      device: $PWD/grav
      o: bind

services:
  grav:
    build: ./
    ports:
      - 8080:80
    volumes:
      - grav-data:/var/www/html
