Description Anshul Verma 2020-11-26 21:02:56 UTC

Description of problem:

The cluster-image-registry-operator, when a request to the associated S3 storage fails with any reason, it leaves the connection created for that request open.
This blocks a port. When this keeps happening, no more ports gets available for new connections and it gives the following error -
~~~
E1019 06:23:08.149459      90 controller.go:311] unable to sync: unable to sync storage configuration: RequestError: send request failed
caused by: Head https://<s3_storage>: dial tcp <ip_address>:443: connect: cannot assign requested address, requeuing

Looking at the PR we are only setting some defaults for timeouts, a regression test should be enough to verify this bug.
Verified on 4.7.0-0.nightly-2021-01-10-070949.
