@teochenglim @tanora do either of you see anything in logs that shows an error specific to S3 or similar?

[teochenglim]

@arschles That's no any helpful error message from the kubernetes pod. All we see is bunch of 200 (/healthz) and 500 (/readyz) status code because of helm charts's readiness. A more verbose debug log option would be helpful.

i think it is from https://github.com/gomods/athens/blob/main/charts/athens-proxy/templates/deployment.yaml#L59-L70

INFO[12:04PM]: incoming request	http-method=GET http-path=/readyz http-status=500
INFO[12:04PM]: incoming request	http-method=GET http-path=/healthz http-status=200
INFO[12:04PM]: incoming request	http-method=GET http-path=/readyz http-status=500

The other possible question is when the endpoint /readyz is not ready, how do we debug it?

[teochenglim]

@arschles

indeed the /readyz seems from this code and it only return the http status
https://github.com/gomods/athens/blob/main/cmd/proxy/actions/readiness.go#L12

If some log is written somewhere would be good.

Or maybe also return the "err" on what ready happen would be so helpful.
https://github.com/gomods/athens/blob/main/pkg/storage/s3/s3.go#L70

The problem can range from permission error, the connection established error would be prefect.
