Why yet another container for Ghost?
The official container for Ghost is fine for running in development mode, but it has the wrong
permissions for running in production. That, and the config file doesn't have any easy way to tweak
This container uses the official Ghost image as it's base, has a more "environment aware"
config.js file, and uses these environment variables to tune the config.
docker run --name some-ghost -d ptimof/ghost
This will start Ghost in development mode listening on the default port of 2368.
If you'd like to be able to access the instance from the host without the
contain's IP, standard port mappings can be used:
docker run --name some-ghost -p 8080:2368 -d ptimof/ghost
Then, access it via
http://host-ip:8080 in a browser.
There are three environment variables that can be configured:
GHOST_URL: the URL of your blog (e.g.,
MAIL_FROM: the email of the blog installation (e.g.,
MAIL_HOST: which host to send email to (e.g.,
These can either be set on the Docker command line directly, or stored in a file and passed on
the Docker command line:
sudo cp ghost.example.env /etc/default/ghost sudo vi /etc/default/ghost docker run --name some-ghost --env-file /etc/default/ghost -p 8080:2368 -d ptimof/ghost
If you have just pulled the Docker image with
docker pull ptimof/ghost, the example
environment file looks like this:
# Ghost environment # Place in /etc/default/ghost GHOST_URL=http://www.example.com MAIL_FROM='"Webmaster" <email@example.com>' MAIL_HOST=mail.example.com
Running in production
The official Ghost image places the blog content in
/var/lib/ghost and exports it as a
This allows two main modes of operation:
Content on host filesystem
In this mode, the Ghost blog content lives on the filesystem of the host with the
1000. If this is acceptable, create a directory somewhere, and use the
-v Docker command
line option to mount it:
sudo mkdir -p /var/lib/ghost sudo chown 1000:1000 /var/lib/ghost docker run --name some-ghost --env-file /etc/default/ghost -p 80:2368 -v /var/lib/ghost:/var/lib/ghost -d ptimof/ghost npm start --production
Content in a data volume
This is the preferred mechanism to store the blog data. Please see the
for backup, restore, and migration strategies.
docker create -v /var/lib/ghost --name some-ghost-content busybox docker run --name some-ghost --env-file /etc/default/ghost -p 80:2368 --volumes-from some-ghost-content -d ptimof/ghost npm start --production
You should now be able to access this instance as
http://www.example.com in a browser.
Behind a reverse proxy
Of course, you should really be running Ghost behind a reverse proxy, and set things up to auto restart. For that,
a reasonable container would be:
docker create --name some-ghost -h ghost.example.com --env-file /etc/default/ghost -p 127.0.0.1:2368:2368 --volumes-from some-ghost-content --restart=on-failure:10 ptimof/ghost npm start --production docker run some-ghost
I've written a bit more about using Ghost as a Docker image:
- Hacking on Ghost themes: a development workflow for modifying a Ghost theme.
- Moving to Docker: Ghost: Running Ghost as a production service in a container.
- Moving to Docker: NGINX reverse proxy with SSL termination: a more complicated example of running Ghost in production, using NGINX to front-end Ghost, and Ghost using SASL (authenticated login) to a mail relay server.
