How To Update Ghost Docker

I recently switched my Ghost installation from Ghost CLI (Command Line Interface) to Ghost and Docker, because it is the recommended way from Ghost.org and it is the only way to get the Fediverse Feature working.

The old way with the cli was really easy. If you’re already running the latest major version (6.x) - update using Ghost CLI by runningCopyAsk AI

ghost update

That’s it! If you want to be super safe, run ghost backup first.

Now I want to update my new Ghost Docker Setup and here is the how to:

Updating Ghost with Docker Compose

Use docker compose to update Ghost regularly

# ensure you're in the directory where you installed ghost and pull the latest configuration
cd /opt/ghost
git pull

# pull the latest images and restart to use them
docker compose pull
docker compose up -d

# optionally clean up old images
docker image prune

Or the one-liner, if you’re in the directory where you cloned the docker tools

git pull && docker compose pull && docker compose up -d

​Updating config

When changing your Ghost config in .env you’ll need to recreate the Ghost container.CopyAsk AI

docker compose up -d --force-recreate ghost

Any time that DOMAIN, ADMIN_DOMAIN or ACTIVITYPUB_TARGET are changed in the .env file, the Caddy container also needs recreating:CopyAsk AI

docker compose up -d --force-recreate ghost caddy

When changing any other environment variables in .env that are used in the compose.yml the service using the variable will also need recreating in the same way.The single exception is the DATABASE_xxx variables. These must not be changed once the database has been initialised, as it will change the config, but not the actual values the database expects, thefore causing connection errors.

And that's all. Everything is working like charme. Except my Server is too small, too lame. I need to upgrade my big iron to run my weblog faster.
