I'm trying to install kubernetes on one of my centos host using kubeadm. But in the same host, there is already running microservices multicontainer application. When i enable the firewalld service while installing kubernetes to allow the ips which are required to the kubernetes, my docker multicontaier application is flushing off its connections. Could anyone please help me to install kubernetes on the same host while my docker application running smooth ? I've tried sequentially starting the applications such as starting docker demon after the firewalld and vice versa but it also not working.
