How to use this image
This will start a Ghost instance listening on the default Ghost port of 2368.
$ docker run -d --name some-ghost ghost
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:
$ docker run -d --name some-ghost -p 3001:2368 ghost
Then, access it via
http://host-ip:3001 in a browser.
Mount your existing content. In this example we also use the Alpine base image.
$ docker run -d --name some-ghost -p 3001:2368 -v /path/to/ghost/blog:/var/lib/ghost/content ghost:1-alpine
$ docker run -d --name some-ghost -p 3001:2368 -v /path/to/ghost/blog:/var/lib/ghost ghost:0.11-alpine
If you want to run Ghost 0.11.xx, be aware of the container’s path difference:
- Ghost 1.x.x is:
- Ghost 0.11.x is:
This Docker image for Ghost uses SQLite. There is nothing special to configure.
Alternatively you can use a data container that has a volume that points to
/var/lib/ghost/content (or /var/lib/ghost for 0.11.x) and then reference it:
$ docker run -d --name some-ghost --volumes-from some-ghost-data ghost
What is the Node.js version?
When opening a ticket at https://github.com/TryGhost/Ghost/issues it becomes necessary to know the version of Node.js in use:
$ docker exec <container-id> node --version v6.11.2
docker stack deploy or
# by default, the Ghost image will use SQLite (and thus requires no separate database container) # we have used MySQL here merely for demonstration purposes (especially environment-variable-based configuration) version: '3.1' services: ghost: image: ghost:1-alpine restart: always ports: - 8080:2368 environment: # see https://docs.ghost.org/docs/config#section-running-ghost-with-config-env-variables database__client: mysql database__connection__host: db database__connection__user: root database__connection__password: example database__connection__database: ghost db: image: mysql:5.7 restart: always environment: MYSQL_ROOT_PASSWORD: example
docker stack deploy -c stack.yml ghost (or
docker-compose -f stack.yml up), wait for it to initialize completely, and visit
http://host-ip:8080 (as appropriate).
ghost images come in many flavors, each designed for a specific use case.
This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.
This image is based on the popular Alpine Linux project, available in the
alpine official image. Alpine Linux is much smaller than most distribution base images (~5MB), and thus leads to much slimmer images in general.
This variant is highly recommended when final image size being as small as possible is desired. The main caveat to note is that it does use musl libc instead of glibc and friends, so certain software might run into issues depending on the depth of their libc requirements. However, most software doesn’t have an issue with this, so this variant is usually a very safe choice. See this Hacker News comment thread for more discussion of the issues that might arise and some pro/con comparisons of using Alpine-based images.
To minimize image size, it’s uncommon for additional related tools (such as
bash) to be included in Alpine-based images. Using this image as a base, add the things you need in your own Dockerfile (see the
alpine image description for examples of how to install packages if you are unfamiliar).
