Bitnami Docker Image for Ghost
Full Description



What is Ghost?

Ghost is a simple, powerful publishing platform that allows you to share your stories with the world

https://ghost.org/

TL;DR;

Docker Compose

$ curl -sSL https://raw.githubusercontent.com/bitnami/bitnami-docker-ghost/master/docker-compose.yml > docker-compose.yml
$ docker-compose up -d

Kubernetes

WARNING: This is a beta configuration, currently unsupported.

Get the raw URL pointing to the kubernetes.yml manifest and use kubectl to create the resources on your Kubernetes cluster like so:

$ kubectl create -f https://raw.githubusercontent.com/bitnami/bitnami-docker-ghost/master/kubernetes.yml

Why use Bitnami Images?

  • Bitnami closely tracks upstream source changes and promptly publishes new versions of this image using our automated systems.
  • With Bitnami images the latest bug fixes and features are available as soon as possible.
  • Bitnami containers, virtual machines and cloud images use the same components and configuration approach - making it easy to switch between formats based on your project needs.
  • Bitnami images are built on CircleCI and automatically pushed to the Docker Hub.
  • All our images are based on minideb a minimalist Debian based container image which gives you a small base container image and the familiarity of a leading linux distribution.

Prerequisites

To run this application you need Docker Engine 1.10.0. Docker Compose is recomended with a version 1.6.0 or later.

How to use this image

Run the application using Docker Compose

This is the recommended way to run Ghost. You can use the following docker compose template:

version: '2'
services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
    volumes:
      - 'mariadb_data:/bitnami'
  ghost:
    image: 'bitnami/ghost:latest'
    labels:
      kompose.service.type: nodeport
    ports:
      - '80:2368'
    volumes:
      - 'ghost_data:/bitnami'
    depends_on:
      - mariadb
    environment:
      - GHOST_HOST=localhost
volumes:
  mariadb_data:
    driver: local
  ghost_data:
    driver: local

Run the application manually

If you want to run the application manually instead of using docker-compose, these are the basic steps you need to run:

  1. Create a new network for the application and the database:

    $ docker network create ghost-tier
    
  2. Start a MariaDB database in the network generated:

    $ docker run -d --name mariadb --net=ghost-tier \
       -e ALLOW_EMPTY_PASSWORD=yes \
       bitnami/mariadb
    

    Note: You need to give the container a name in order to Ghost to resolve the host

  3. Run the Ghost container:

    $ docker run -d -p 80:2368 --name ghost --net=ghost-tier bitnami/ghost
    

Then you can access your application at http://your-ip/

Note! If you want to access your application from a public IP or hostname you need to properly configured Ghost . You can handle it adjusting the configuration of the instance by setting the environment variable GHOST_HOST to your public IP or hostname.

Persisting your application

If you remove the container all your data and configurations will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a volume at the /bitnami path. Additionally you should mount a volume for persistence of the MariaDB data.

The above examples define docker volumes namely mariadb_data and ghost_data. The Ghost application state will persist as long as these volumes are not removed.

To avoid inadvertent removal of these volumes you can mount host directories as data volumes. Alternatively you can make use of volume plugins to host the volume data.

Mount host directories as data volumes with Docker Compose

This requires a minor change to the docker-compose.yml template previously shown:

version: '2'

services:
  mariadb:
    image: 'bitnami/mariadb:latest'
    environment:
      - ALLOW_EMPTY_PASSWORD=yes
    volumes:
      - /path/to/mariadb-persistence:/bitnami
  ghost:
    image: bitnami/ghost:latest
    depends_on:
      - mariadb
    ports:
      - '80:2368'
    volumes:
      - '/path/to/ghost-persistence:/bitnami'

Mount host directories as data volumes using the Docker command line

In this case you need to specify the directories to mount on the run command. The process is the same than the one previously shown:

  1. Create a network (if it does not exist):

    $ docker network create ghost-tier
    
  2. Create a MariaDB container with host volume:

    $ docker run -d --name mariadb --net ghost-tier \
     -e ALLOW_EMPTY_PASSWORD=yes \
     --volume /path/to/mariadb-persistence:/bitnami \
     bitnami/mariadb:latest
    

    Note: You need to give the container a name in order to Ghost to resolve the host

  3. Create the Ghost container with host volumes:

    $ docker run -d --name ghost -p 80:2368 --net ghost-tier \
     --volume /path/to/ghost-persistence:/bitnami \
     bitnami/ghost:latest
    

Upgrade this application

Bitnami provides up-to-date versions of MariaDB and Ghost, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container. We will cover here the upgrade of the Ghost container. For the MariaDB upgrade see https://github.com/bitnami/bitnami-docker-mariadb/blob/master/README.md#upgrade-this-image

  1. Get the updated images:

    $ docker pull bitnami/ghost:latest
    
  2. Stop your container

    • For docker-compose: $ docker-compose stop ghost
    • For manual execution: $ docker stop ghost
  3. Take a snapshot of the application state

$ rsync -a /path/to/ghost-persistence /path/to/ghost-persistence.bkp.$(date +%Y%m%d-%H.%M.%S)

Additionally, snapshot the MariaDB data

You can use these snapshots to restore the application state should the upgrade fail.

  1. Remove the currently running container

    • For docker-compose: $ docker-compose rm ghost
    • For manual execution: $ docker rm ghost
  2. Run the new image

    • For docker-compose: $ docker-compose start ghost
    • For manual execution (mount the directories if needed): docker run --name ghost bitnami/ghost:latest

Configuration

Environment variables

When you start the ghost image, you can adjust the configuration of the instance by passing one or more environment variables either on the docker-compose file or on the docker run command line. If you want to add a new environment variable:

  • For docker-compose add the variable name and value under the application section:
ghost:
  image: bitnami/ghost:latest
  ports:
    - 80:2368
  environment:
    - GHOST_HOST=my_host
  • For manual execution add a -e option with each variable and value:
 $ docker run -d -p 80:2368 --name ghost --network=ghost-tier \
    -e GHOST_PASSWORD=my_password \
    -v /your/local/path/bitnami/ghost:/bitnami \
    bitnami/ghost

Available variables:

  • GHOST_HOST: Hostname for Ghost.
  • GHOST_PORT_NUMBER: Port number used in the generated application URLs. Default: 80
  • GHOST_USERNAME: Ghost application username. Default: user
  • GHOST_PASSWORD: Ghost application password. Minimum length is 10 characters. Default: bitnami123
  • GHOST_EMAIL: Ghost application email. Default: user@example.com
  • BLOG_TITLE: Ghost blog title. Default: User's Blog
  • MARIADB_USER: Root user for the MariaDB database. By default: root.
  • MARIADB_PASSWORD: Root password for the MariaDB database.
  • MARIADB_HOST: Hostname for MariaDB server. Default: mariadb
  • MARIADB_PORT_NUMBER: Port used by MariaDB server. Default: 3306

SMTP Configuration

To configure Ghost to send email using SMTP you can set the following environment variables:

  • SMTP_HOST: SMTP host.
  • SMTP_PORT: SMTP port.
  • SMTP_USER: SMTP account user.
  • SMTP_PASSWORD: SMTP account password.
  • SMTP_SERVICE: SMTP service to use.

This would be an example of SMTP configuration using a GMail account:

  • docker-compose:
  ghost:
    image: bitnami/ghost:latest
    ports:
      - 80:2368
    environment:
      - SMTP_HOST=smtp.gmail.com
      - SMTP_USER=your_email@gmail.com
      - SMTP_PASSWORD=your_password
      - SMTP_SERVICE=GMail
  • For manual execution:
 $ docker run -d -p 80:2368 --name ghost --network=ghost-tier \
    -e SMTP_HOST=smtp.gmail.com \
    -e SMTP_SERVICE=GMail \
    -e SMTP_USER=your_email@gmail.com \
    -e SMTP_PASSWORD=your_password \
    -v /your/local/path/bitnami/ghost:/bitnami \
    bitnami/ghost

Notable Changes

0.11.10-r2

  • The ghost container has been migrated to a non-root container approach. Previously the container run as root user and the ghost daemon was started as ghost user. From now own, both the container and the ghost daemon run as user 1001.
    As a consequence, the configuration files are writable by the user running the ghost process.
