Double checking *how* to upgrade 4CAT with docker from the command-line

I can see the instructions for upgrading 4CAT here:
https://github.com/digitalmethodsinitiative/4cat/wiki/Upgrading-4CAT

I am specifically interested in the docker approach. Just double checking that it is sufficient to
just update the .env and docker-compose.yml files (i.e. get newer 4CAT image), and that it is
not necessary to update the rest of the files from the github repo (e.g. with git pull or similar)?

If I understand you correctly, it would indeed be sufficient to update docker-compose.yml and .env. This Docker Compose file pulls images from DockerHub, so it does not rely on the local source code to build 4CAT. If you want to build your own containers based on local source code, you would use docker-compose_build.yml instead.

We don't really have instructions on how to upgrade in the latter case, since typically this would be done to be able to make your own changes to the code, in which case upgrading is tricky (since updates may not be compatible with your changes, etc).

Great, thanks for the clarification. You may close the issue.
