Upgrade Ghost 1.22 to 2.1.3

A few months ago I wrote about upgrading this blog's Ghost version from version 0.x to 1.x. Since version 2 has been out, here is how the upgrade went.

Since I am using ghost in a docker container, I did'nt use the ghost cli tool. I need to update the docker containers, which is much easier.

First lets check what docker images we have running currently:

hacksaw% docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
ghost               2.1.3               cf385d0ac3f4        3 days ago          566MBhacksaw%

Ghost does not have a way to easily view what version you running. You need to peek into the config for that, so in my case I needed to log into the container first:

Here is the running container:

docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                                PORTS                    NAMES
b7703cf1baae        ghost               "docker-entrypoint.s…"   10 seconds ago      Up 9 seconds                >2368/tcp   ghost-v1-2

and this is how we log into the running container to verify the version of ghost:

docker exec -it ghost-v1-2 /bin/[email protected]:/var/lib/ghost# lsconfig.development.json  config.production.json  content  content.orig	current  versions
[email protected]:/var/lib/ghost# cat versions/cat: versions/: Is a directory
[email protected]:/var/lib/ghost# cd versions/
[email protected]:/var/lib/ghost/versions# ls 1.22.0

[email protected]:/var/lib/ghost/versions/1.22.0# less package.jsonbash: less: command not found
[email protected]:/var/lib/ghost/versions/1.22.0# cat package.json
{"name": "ghost",
"version": "1.22.0",

Before we go straight to v2, we need to be on the latest v1, which was 1.25.5.

So lets get that container, by running it. This command will pull that version, and run it:

docker run -d --name ghost-v1.25.5 -p 4431:2368 --restart always -v /home/yusufm/gitwork/ghost-data-v1:/var/lib/ghost/content -e url=http://aws.hacksaw.co.za/blog/ ghost:1.25.5

After verifying that ghost is up and running, we can now go to version 2.1.3

docker run -d --name ghost-v2.1.3-1 -p 4431:2368 --restart always -v /home/yusufm/gitwork/ghost-data-v1:/var/lib/ghost/content -e url=http://gcp.hacksaw.co.za/blog/ ghost:2.1.3

In my case, I have two VMs, in AWS and GCP, and I run the ghost data files in git. I upgraded the AWS site first, which went fine. But on the GCP site, I forgot to to the intermediary step of going to v1.15.5 first, rather I went straight to v2.1.3. The ghost container refused to start, even when trying to go back to the original version. I resolved it by pulling the updated config via git, and then running 2.1.3.
