"WARN docker-compose.yml: version is obsolete" when starting or stopping bitwarden

[vinnyperella]

This is low priority as it doesn't appear to cause any issues and is just a WARN but it might confuse people and make them think there's an issue. I updated my docker compose to v2.25.0 which is the latest version and when I ran "./bitwarden.sh stop" or "./bitwarden.sh start" I received the following warning.

WARN[0000] /opt/bitwarden/bwdata/docker/docker-compose.yml: version is obsolete

One of the changes in docker compose v2.25.0 is to bump compose-go to v2.0.0.

https://github.com/docker/compose/releases
docker/compose#11623

And one of the changes for compose-go v2.0.0 is to "warn user version is obsolete".

https://github.com/compose-spec/compose-go/releases/tag/v2.0.0
compose-spec/compose-go#575

From the above pull request.

Since compose-specification was released, version attribute is obsolete as it doesn't guarantee any form of compatibility. While users adopted new features introduced in the spec, we still see many of them using version: "3" in compose files.

This adds a warning to encourage users to stop using this useless attirbute

bitwarden@bitwarden:/opt/bitwarden$ grep -i version bwdata/docker/docker-compose.yml 
version: '3'
bitwarden@bitwarden:/opt/bitwarden$

This is not a duplicate of #222 this is a completely different issue. It's complaining about the "version: '3'" parameter inside the docker-compose.yml file that's used to start Bitwarden. In the latest version of the docker compose binary the version parameter is deprecated.

[GrahamTolhurst]

I have to agree with @vinnyperella, this issue is not related to #222
I've manually commented out the version line in docker-compose.yml, and the warning is no longer given when starting bitwarden. It appears the current docker-compose.yml is not fully compatible with the latest docker compose version. Removing the version line makes it compatible.

[vinnyperella]

@Greenderella could you please reopen this issue? It's not a high priority since it's just a warning but as I mentioned in my initial issue post it could cause some concern for people running Bitwarden self-hosted that are not aware of the reason for the warning. The solution should be to remove the version parameter from docker-compose.yml as @GrahamTolhurst mentioned the parameter is obsolete anyway.

[Greenderella]

Sorry, I misinterpreted the issue. This has been escalated for further investigation. If you have more information that can help us, please add it below.
