Description Sam Fowler 2021-01-22 01:12:09 UTC 
Rootless containers run with Podman, in versions from 1.8.0 onward, receive all traffic with a sourceIP of 127.0.0.1 (including from remote hosts). This can impact containerized applications that trust localhost (127.0.01) connections by default and do not require authentication.
