Run Ghost

Docker hosts an official image for Ghost on Docker Hub.

1. Pull the Ghost image from Docker Hub:

   docker pull ghost
   

2. Run the Ghost image in a new container:

   docker run -d \
     -e NODE_ENV=development \
     -e url=http://localhost:3001 \
     -e database__connection__filename=/var/lib/ghost/content/data/ghost-dev.db \
     -p 3001:2368 \
     -v ghost-vol:/var/lib/ghost/content \
     ghost
   

   • -d runs the image in detached mode to avoid blocking the terminal.
   • -e NODE_ENV=development sets an environment variable within the container. This tells Ghost to run in "development" mode (rather than "production", for instance)
   • -e url=http://localhost:3001 sets another environment variable, this one tells Ghost that we want to be able to access Ghost via a URL on our host machine.
   • -e database__connection__filename=/var/lib/ghost/content/data/ghost-dev.db specifies where Ghost stores its SQLite database.
   • We've used -p before. -p 3001:2368 does some port-forwarding between the container and our host machine.
   • -v ghost-vol:/var/lib/ghost/content mounts the volume we created at Ghost's content directory, so its files, including the database, survive when we replace the container.
3. Navigate to http://localhost:3001/ in your browser, you should see your new Ghost CMS!

Run and submit the CLI tests against http://localhost:3001.
