Pair Docker and Ghost for the perfect platform to run your blog!

Find out more about Ghost here

Ghost is an elegant and minimal blogging platform that focus on simplicity. One of its most attractive features is its Markdown editor. It's also fully hackable running on Node.js with the Handlebars view-engine.

This project is work-in-progress but all the blog images are fully working

Ghost 1.0

Ghost 1.0 was released in July 2017 you can find the Dockerfile here and a Getting Started blog post here.

For now I'd still recommend using Ghost 0.11.x which has better support for running in Docker under a known configuration. Check back soon for more on Ghost 1.0.

Ghost 0.11.x

The rest of these instructions are for the version of Ghost running at and many other sites.

Getting started

You can pull the ARMv7 image (for PI2/3) straight from the Docker Hub docker pull alexellis2/ghost-on-arm:armv7. The image for your PC, laptop or cloud host is - alexellis2/ghost-on-docker:latest.

To get the latest and greatest versions you can build your own image using the Dockerfile provided. If you'd like to help maintain or test new versions please do so through pull requests.

Please support the project by giving it a Star.


These are all based upon Node 4.x, pick the architecture for your computer/server. If you are using a regular PC it will be the first option marked x86_x64. Each image has been pushed to the Docker hub, the npm modules alone for Ghost take up around 500MB, but the download will be faster than a fresh build if you use a Raspberry PI.

  • Regular PC/Laptop - x86_x64
  • Dockerfile
  • Based upon Alpine Linux
  • Very fast build time and high amount of requests/per second compared to a Raspberry PI, my Core i5 NUC with 16GB RAM running a single container gave around 85-90 requests/per second.

Example usage:

$ docker run --name blog -d -p 80:2368 alexellis2/ghost-on-docker:latest

Or use the recently added Docker Compose file for even less fuss:

$ docker-compose up -d
  • ARMv7 (Raspberry PI 2 / 3)
  • Dockerfile
  • Building SQLite npm module on PI 2 takes about 7 minutes
  • semver and other required modules will take quite some time
  • Once up and running can handle 12-16 requests per second
  • Nginx is beneficial as a cache (dramatically improving requests/per second), but not absolutely necessary.

Example usage:

$ docker run --name blog -d -p 80:2368 alexellis2/ghost-on-docker:armv7
  • ARMv6 (Raspberry PI A/B/B+/Zero)
  • Dockerfile
  • Note: ARMv6, especially models with < 512mb RAM will require a swapfile for building the SQLite npm module. Creating SWAP file
  • Building SQLite npm module on PI Zero takes about 16 minutes
  • Once up and running performs 2-3 requests per second, use of Nginx or another cache is highly recommended.

Example usage:

$ docker run --name blog -d -p 80:2368 alexellis2/ghost-on-docker:armv6


One of the simplest ways you can benchmark your blog is to use Apache Bench. It has a very simple CLI, here's an example load:

On the Docker host:

$ docker run --name blog -d -p 80:2368 alexellis2/ghost-on-docker:latest

From another PC:

$ ab -c 4 -n 1000
  • -c 4 means 4 concurrent requests, simulating three users hitting the page at exactly the same time
  • -n 1000 means 1000 requests, so each of the 4 users will hit the page a portion of that time. i.e. 250 requests each.

You can play with the numbers to see how the blog performs under different conditions, you could also try typing in docker stats to see what kind of load the Docker container is creating.

Taking it further

  • Learn how to apply caching on your blog with NGinx.

  • Use Docker volumes to safely upgrade your blog and preserve your data

Keeping Shipping your blog with Docker volumes

There is also an example docker-compose.yml file in this repository which you can use as a template for mounting a persistent volume.
