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

Custom port

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://localhost:3001 or http://host-ip:3001 in a browser.

Stateful

Mount your existing content. In this example we also use the Alpine base image.

Ghost 1.x.x

$ docker run -d --name some-ghost -p 3001:2368 -v /path/to/ghost/blog:/var/lib/ghost/content ghost:1-alpine

Ghost 0.11.xx

$ docker run -d --name some-ghost -p 3001:2368 -v /path/to/ghost/blog:/var/lib/ghost ghost:0.11-alpine

Breaking change

If you want to run Ghost 0.11.xx, be aware of the container's path difference:

  • Ghost 1.x.x is: /var/lib/ghost/content
  • Ghost 0.11.x is: /var/lib/ghost

SQLite Database

This Docker image for Ghost uses SQLite. There is nothing special to configure.

Docker Volume

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

... via docker stack deploy or docker-compose

Example stack.yml for ghost:

# 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

Run docker stack deploy -c stack.yml ghost (or docker-compose -f stack.yml up), wait for it to initialize completely, and visit http://swarm-ip:8080, http://localhost:8080, or http://host-ip:8080 (as appropriate).

Image Variants

The ghost images come in many flavors, each designed for a specific use case.

ghost:<version>

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.

ghost:alpine

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 git or 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).

@lyndon160 if you have deployed ghost as part of a swarm you can just update the ghost service using docker service update and passing in the image version. More here

How do you recommend we update our Ghost docker image? Use volumes and just update replace the primary container?

are there instructions or a guide anywhere to upgrade from 0.11.x to 1.0?

I have this container running ghost 0.11.10 with a data volume mounted (directory is on host not in its own container)

I tried just launching the 1.0 ghost image with the new path and it would not start

Is there a way to use my own config file with 1.7.1 ghost?

@rgarrigue @zeppelinux
just set environment variables:

NODE_ENV=production
url=https://yourdomain.com

please note that url is lowecase.
I guess you can set other configuration through env. variables, but I never tried.
Hope this helps :)

Agree with rgarrigue, definetely an 'issue' in 1.7.1 image.

Latest image got an "issue" : doc say you should put /var/lib/ghost/current/content/ on a volume, but config.production.json is located in /var/lib/ghost/ which make it non persistent. And there's the localhost:2368 there that got to be updated if you want your link going to yourdomain.com.

What about updating nginx in docker base image?

Not sure if I did something weird or if this is documented somewhere, but it looks like the content directory is actually:

/var/lib/ghost/current/content/

which is a symlink to /var/lib/ghost/versions/1.5.0.
