dotnet SDK fails (dotnet 8.0) #1186

Open msthtrifork opened 1 month ago

When running the pack cli with the paketo builder with a dotnet 8.0 application in a Gitlab CI environment we (sometimes) get the following error:

unexpected EOF
ERROR: failed to build: exit status 1
ERROR: failed to build: executing lifecycle: failed with status code: 51

The error is:

unexpected EOF
ERROR: failed to build: exit status 1
ERROR: failed to build: executing lifecycle: failed with status code: 51

The most frustrating thing is that this error appears maybe every 2-3 builds, sometimes everything works and the image is built.

We don't get any more info of the error when running with:

BP_DOTNET_PUBLISH_FLAGS: "--verbosity=detailed" BP_LOG_LEVEL: "DEBUG"

What can "unexpected EOF" mean in this instance?

Expected Behavior

Dotnet 6.0 applications behave as they should and when we upgraded to dotnet 8 we see this error.

Current Behavior

unexpected EOF ERROR: failed to build: exit status 1 ERROR: failed to build: executing lifecycle: failed with status code: 51

Possible Solution

Maybe it has something to do with running docker-in-docker (with the pack cli) inside a kubernetes cluster (the gitlab runners run in the kubernetes cluster). I know its very complex ;-) We rooted out OOM in the pods.

Steps to Reproduce

I know its hard to reproduce. We are hoping for some guidance into further investigating this bug. I am also willing to submit PRs with a solution is possible.

Let me know if you want me to add further info!
