Question

Hi, we are using gcr.io/alloydb-connectors/alloydb-auth-proxy and we are observing a huge amount of logs being generated by the container.

We reached over 1 million log entries over the past month. Is there any way to set the log level to "warn" so that these info messages are not logged to the console?

You're looking for the --quiet flag which will only log error messages.

[FezVrasta]

Thanks, I don't think that's documented though?

[enocom]

If you run ./alloydb-auth-proxy --help, it does appear in the list of flags.

We could reproduce that help message here in the repository if that would help. WDYT?

[FezVrasta]

Yes that would be extremely helpful, having ran this project exclusively through kubernetes and its container I never had a chance to play with the CLI tool.

[enocom]

Sounds good. I'll make this an issue for doing that. Thanks again for the report.
