I recently updated the blog to run on Ghost 3. Since I've moved to docker, the upgrade was exceedingly simple, although it was a bit more involved than if I had kept up with updates.
The update process went a bit like this:
- Backup data using the Ghost export
- Stop Container
- Edit Docker Compose to the required version tag (
- Pull the image
- Start the container
- Verify that everything works correctly.
However, since I was not running the latest 2.x version, I first had to update to 2.38 using the above process and change to use a specific tag in my docker compose file.
Overall, pretty painless compared to my migration from 0.x to 2.x, which didn't have any documentation and involved migrating from a non-official docker image to an official one.
