[BUG] -.json:10,5-19: Invalid name; only "[a-zA-Z0-9_-]+" are allowed #12919
Description
Description
It seems that recent change to docker compose and usage of bake by default to build images have introduced some incompatibility. Service names containing a dot character are valid according to the spec. Yet when building docker compose projects with service names with dots I'm getting:
-.json:10,5-19: Invalid name; only "[a-zA-Z0-9_-]+" are allowed
https://github.com/laravel/sail/issues/786 - I've noticed it while using laravel sail which defines it's base service name as laravel.test.
When one does docker config > bake.yaml and then docker buildx bake -f bake.yaml everything builds as expected. Only running docker compose up and similar gives the error.
Steps To Reproduce
- Create
compose.ymlwith contents like:services: this.is.a.test: build: context: . dockerfile: Dockerfile - Create
Dockerfile:FROM scratch - Run
docker compose up. - Error happens here.

Wonderful day! ✨
The only place with the regex mentioned found:
Source
And, it seems like the message originates from:
Source
Therefore, it could be a Dockerfile target.

I've just confirmed that #12925 has fixed the issue.
