Supported tags and respective
For detailed information about the published artifacts of each of the above supported tags (image metadata, transfer size, etc), please see the
repos/ghost directory in the
docker-library/repo-info GitHub repo.
For more information about this image and its history, please see the relevant manifest file (
library/ghost). This image is updated via pull requests to the
docker-library/official-images GitHub repo.
How to use this image
$ docker run --name some-ghost -d ghost
This will start a Ghost instance listening 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:
$ docker run --name some-ghost -p 8080:2368 -d ghost
Then, access it via
http://host-ip:8080 in a browser.
You can also point the image to your existing content on your host:
$ docker run --name some-ghost -v /path/to/ghost/blog:/var/lib/ghost ghost
Alternatively you can use a data container that has a volume that points to
/var/lib/ghost and then reference it:
$ docker run --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 v4.4.7
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).
Supported Docker versions
This image is officially supported on Docker version 17.04.0-ce.
Support for older versions (down to 1.6) is provided on a best-effort basis.
Please see the Docker installation documentation for details on how to upgrade your Docker daemon.
