I have created docker swarm cluster with
manager (RockyLinux 8.5 and docker 20.10.12)
worker-1 (RockyLinux 8.5 and docker 20.10.12)
worker-2 (RockyLinux 8.5 and docker 20.10.12)
disabled selinux and configured firewalld with all required ports and services in all nodes
I have created overlay network proxy-backend deployed a stack web with two services through proxy-backend network.
web_nginx running on worker1
web_mysql running on worker2
The issue is I’m unable to connect from web_nginx to web_mysql
telnet web_mysql 3306
But it’s working when deploying both service in same node like
web_nginx running on worker1
web_mysql running on worker1
Unable to connect services running on different nodes with same network.
I have configured same infrastructure on CentOS 7 and it working as expected.
We didn’t get any clue where it blocks in RockLinux.
Can any one help on this?
