[Solved] Upgrading MM docker from v7.8 to v8

I am trying to update my MM docker installation from v7.8 to v8, and I was hoping to get some tips on how to achieve this without breaking my installation.

In my .env I have MATTERMOST_IMAGE_TAG=latest.

After backing up my postgre db, I run:

 sudo docker-compose -f docker-compose.yml -f docker-compose.without-nginx.yml down
 sudo docker-compose pull
 sudo docker-compose -f docker-compose.yml -f docker-compose.without-nginx.yml up

After checking my installation, I see that I have successfully upgraded my installation, from v7.8 (ESR) to version v7.10, but not to v8. Upon checking https://hub.docker.com/r/mattermost/mattermost-team-edition/tags, I see that indeed the version corresponding to the latest release tag is v.7.10.

My question is, can I just change the env tag to MATTERMOST_IMAGE_TAG=release-8.0 and do a pull to get the latest release? I would be going from v7.10 to v8.

Hello , I achieved this by setting the image name for V8 in the mattermost image tag on your docker-cimpose.yml .Hope this helps.
