[BUG] Docker compose build doesn't use buildkit?

[TE-9004095894]

Description

After upgrading the docker-compose-plugin, the command
docker compose build now displays the old style (pre-buildkit).
It appears that buildkit is not being used.

The version information is as follows:
・2.39.1-1~ubuntu.24.04~noble
Downgrading to the previous version
・2.38.2-1~ubuntu.24.04~noble
resolves the issue.

The docker version is as follows:

$ docker --version
Docker version 28.3.3, build 980b856
$ docker compose version
Docker Compose version v2.39.1

Even with the same docker-compose.yaml file, if the command is "docker buildx bake", it will be displayed in buildkit style.

If the command is "docker compose build", it will not work.

Seems to work fine with Docker Compose version HEAD-0dc9852. So, it's likely already fixed(at least under certain conditions) and just waiting to be released.

Hello @yusufkandemir
I'm glad to hear that your issue seems to have already been resolved in the main branch.
Can you double if you don't have the BUILDKIT_PROGRESS env variable also setup which could have explain this behaviour?

[yusufkandemir]

@glours it's not set

➜ echo $BUILDKIT_PROGRESS

[glours]

Hey @yusufkandemir
Compose v2.39.2 has been released last Friday, can you test it and confirm you can't reproduce the issue?

[yusufkandemir]

@glours all good, thanks! #13144 is also working fine now.

➜ docker compose version
