Yum is not working inside docker container

Hi Guys,

I launched one CentOS container. But I am not able to ping google with name and also not able to run yum command inside docker container.

How can I solve this problem?

Sometime dns is not able to resolve network problem in the containers. To avoid this follow the below given steps.

$ firewall-cmd --zone=public --add-masquerade --permanent
$ firewall-cmd --zone=public --add-port=80/tcp
$ firewall-cmd --zone=public --add-port=443/tcp

After setting port no, you have to reload firewall in your system

$ firewall-cmd --reload

Now try to start your docker and launch one container. It will work.
