Ghost is a free and open source blogging platform written in JavaScript and distributed under the MIT License, designed to simplify the process of online publishing for individual bloggers as well as online publications.
By default, a Ghost instance will be launchd on the default Ghost port of 2368.
If you'd like to be able to access the instance from the host without the container's IP, standard port mappings can be used:
8080:2368
Then, access it via http://localhost:8080 or http://host-ip:8080 in a browser.
You can also point the image to your existing content on your host:
/path/to/ghost/blog:/var/lib/ghost
Alternatively you can use a data container that has a volume that points to /var/lib/ghost and then reference it
