I'm new to docker and okd. I'm using okd 3.11 all in one in my ssdnodes vm running CentOS Linux 8 (Core). Installed it using oc cluster up --public-hostname="hostname" --base-dir="/path". When I try to build an application from api or cli I get the error at git clone.
WARNING: timed out waiting for git server, will wait 1m4s
error: fatal: unable to access 'https://github.com/sclorg/cakephp-ex/': Could not resolve host: github.com; Unknown error```
I tried by turning off firewalld but that did not help.
I can ping github.com from main VM but from docker-registry its not pinging any external url/ip.
cat /etc/resolv.conf
