Feature Flag Service doesn't start when built from repository | server file "missing"

[kainawroth]

Bug Report

OpenTelemetry Demo 1.4

Symptom

When I build from https://github.com/open-telemetry/opentelemetry-demo with docker compose build, the Feature Flag Service doesn't start and shows in Logs exec /app/bin/server: no such file or directory even though the file is present:

When I instead fetch the images from ghcr with docker compose up --no-build, the Feature Flag Service starts without any problems.

Solution

I saved the server file in question from the ghcr image and added it to the version built from the repository, and it fixed the issue:

Reproduce

Build from https://github.com/open-telemetry/opentelemetry-demo repository.

Additional Context

The file from the ghcr image is 2 Bytes bigger (223 Bytes vs 221 Bytes when composed from the repository) even though the content is the same. Attached are both files for comparison:

Hello @kainawroth 👋🏽 ,

Which OS are you using?

[kainawroth]

Hi @julianocosta89,

I'm using Docker Desktop on Windows 11.

[julianocosta89]

@kainawroth is this issue gone?

[kainawroth]

@julianocosta89, I just wanted to check, but I don't even get that far. When I try to compose from the demo repo or from my fork, I'm stuck at the following:

I won't cancel, but it doesn't stop building either.

[julianocosta89]

Hmmm, that is odd.
I know that it may be a lot of pain, but would you be able to run a docker system prune -a, and then, try again?

[kainawroth]

Thanks, that helped. Unfortunately, I'm still running into the same issue and have to replace the server file after deployment.

[julianocosta89]

@tsloughter have you ever seen this???

[joshleecreates]

I'm not able to recreate this on ARM64/MacOS — if I have time I will attempt with windows later today.

[tsloughter]

Has anyone else with Windows 11 tried and reproduced?

[julianocosta89]

@tsloughter we got another user in slack reporting the same issue in Windows 11 and Docker Desktop.
Any ideas what could be the culprit?

[IrrelevantElephant]

I had the same issue with Docker Desktop and Windows 10. I believe the issue is with line endings in the Feature Flag Service source files. When I converted from CRLF to LF it built and ran without issue.

@kainawroth try configuring your git client to checkout with Unix style line endings rather than windows https://docs.github.com/en/get-started/getting-started-with-git/configuring-git-to-handle-line-endings#global-settings-for-line-endings

Also running in WSL worked without issue.

[tsloughter]

@julianocosta89 na, no idea. I can ask around to find Erlang Windows users and see if anyone has experienced similar.

[puckpuck]

Is this still something that we need to track? Do we need to document to use WSL if developing on Windows?

[austinlparker]

Closing this as part of issue cleanup. If there's anything that needs to be done, please create a new issue.

FF Service issues will be mooted by #1388
