I have installed Oracle VM and created a centos 7 machine in which I have installed Docker successfully
then I installed jenkins from docker image : jenkins/jenkins
in that I am not able to install plugins, it is giving me below error: java.net.UnknownHostException: mirrors.tuna.tsinghua.edu.cn
I have reinstalled couple of times but the problem still exists.
I tried to ping google in jenkins container and that is working fine.
Please help me out here.
I have found solution for this. The mirror was not working for my system due to network level restriction. After removing that it is working fine now.
