(Intermediate) Docker image's error log not in stderr

[rishabhpoddar]

The repo containing the Dockerfile and the entrypoint is here.

Could you please elaborate the issue. I'm willing to work on the Dockerfile

[rishabhpoddar]

@AnmolVirdi , the core has two types of outputs:

1. Debug / info logs
2. Error logs

Without docker, the output of (1) is sent to a file called info.log, and output of (2) is sent to error.log. In the code, the error logs are printed using System.err.println, here and the info logs are printed using System.out.println, here.

The problem comes in the docker container, where both these types of logs are being printer to the STDOUT instead of one being printed to STDOUT and one to STDERROR.

Has anyone been able to reproduce this?

I forced an error by putting an exclamation mark before core_config_version in config.yaml and colored stderr red:

It appears to work.

Okay thanks. We will recheck this

It seems that https://github.com/supertokens/supertokens-core/blob/master/src/main/java/io/supertokens/webserver/WebserverAPI.java#L161 and https://github.com/supertokens/supertokens-core/blob/master/src/main/java/io/supertokens/webserver/WebserverAPI.java#L179 don't print out on stderr which is perhaps the root of the issue here.

@rishabhpoddar, is the issue still relevant? Can I take it up?
