[Bug 1233690] Docker containers are not reachable from network after OS update from 20241114 to 20241115

https://bugzilla.suse.com/show_bug.cgi?id=1233690 https://bugzilla.suse.com/show_bug.cgi?id=1233690#c10 --- Comment #10 from Alexandre Vicenzi <alexandre.vicenzi@suse.com> --- I managed to reproduce a scenario where the container does not have internet. It only happens when using iptables v1.8.11 (nf_tables) not iptables v1.8.11 (legacy). To reproduce this issue I had to do the following:
sudo iptables-legacy -F sudo iptables-legacy -X sudo iptables -F sudo iptables -X sudo systemctl restart docker docker run --rm alpine ping -c 4 1.1.1.1
The result was:
PING 1.1.1.1 (1.1.1.1): 56 data bytes --- 1.1.1.1 ping statistics --- 4 packets transmitted, 0 packets received, 100% packet loss
The current workaround is to remove iptables-backend-nft, reset iptables rules, and restart Docker. -- You are receiving this mail because: You are on the CC list for the bug.
