How to rotate log files of Quay containers?

Environment

• Red Hat Quay
  • 3.x

Issue

• The logrotate configurations for nginx were found inside the quay image but it seems like the log rotation does not work.
• How can one configure log rotation for quay container files? Can one use the parameter FEATURE_ACTION_LOG_ROTATION?

Resolution

• Quay containers do not have a logrotate binary. nginx logs are forwarded to /dev/stdout by default. And are governed by the container runtime one is using.

• The FEATURE_ACTION_LOG_ROTATION concerns audit logs stored in Quay's database under the logrotate3 table. It can't be used to rotate container logs.

Diagnostic Steps

• Check if logrotate rpm comes with quay image using below steps:

      $ podman run --rm -it --entrypoint /bin/bash registry.redhat.io/quay/quay-rhel8:v3.7.6
