podman endpoints cfg issue #34522

receiver/podman

What happened?

Description

The endpoint used differs from the one configured. An exrta "/" is injected for unknown reasons

"dial unix /run//podman/podman.sock: "

but configured is

"endpoint: unix://run/podman/podman.sock"

Maybe docs are buggy and we ned to use escape for ":" or /"?

rogercoll · 2024-08-08T17:20:38Z

Thanks for raising this.

The connection strategy was mostly copy/paste from https://github.com/containers/podman/blob/main/pkg/bindings/connection.go#L90. And you are correct, the implementation is adding an extra "/" for non-absolute paths unix sockets. I reckon that both forms should work in most situations, but relying on unix:/// is safer when specifying absolute paths to avoid any possible misinterpretation by the system or application.

Does your socket exist in /run/podman/podman.sock?

cforce · 2024-08-08T22:56:14Z

Yes, looks all good for me - I have added below debug logs in same shell where otelcol is executed later

echo "podman info:"
podman info

echo "Debugging info"
echo "XDG_RUNTIME_DIR=$XDG_RUNTIME_DIR"
ls -al  $XDG_RUNTIME_DIR/*.sock || true
echo "/run/user/podman/"
ls -al  /run/user/podman/*.sock || true

and output

Ok --Path was wrong.

rogercoll · 2024-08-09T06:16:56Z

Ok --Path was wrong.

Great we found out the root problem, do you think we can close the issue?

cforce · 2024-08-09T09:49:57Z

I still think the message and the wrong path composed because of some strange fallback default is completely misleading and shall be improved

rogercoll · 2024-08-12T12:43:15Z

Although the receiver is just propagating the error retrieved from the libpod package, I agree that the error message could be improved. Regarding the path fallback strategy, I would prefer to rely on what the containers/podman package does.

@cforce Would you be interested in opening a PR to improve the error message?
