I'm trying to use a git repo URL in my docker-compose.yml file, as described here. The service looks like this:
app:
build: "https://[MY_GITHUB_OAUTH_TOKEN]@github.com/org/repo.git#develop"
I get the following error:
$ docker-compose up
[+] Running 0/1
⠿ app Error 0.5s
[+] Building 0.0s (1/1) FINISHED
=> CACHED [internal] load git source https://[MY_GITHUB_OAUTH_TOKEN] 0.0s
failed to solve: rpc error: code = Unknown desc = failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount730635615/https:/[MY_GITHUB_OAUTH_TOKEN]@github.com/org/repo.git#develop/Dockerfile: no such file or directory
BUT, when I copy the exact URL from my docker-compose.yml file, I can use it with Docker build successfully. I can see all steps of the Dockerfile being executed.
$ docker build https://[MY_GITHUB_OAUTH_TOKEN]@github.com/org/repo.git#develop
There is a develop branch, [MY_GITHUB_OAUTH_TOKEN] is my actual GitHub token, and there is a valid Dockerfile (with a capital D) in the repo root. Why would this work with docker build but not docker-compose? It can't be an issue with the token, since it works with docker build.
If it matters, I'm on an M1 Mac with Docker for Mac installed. docker-compose is working fine with other services.
