Fresh docker 19.03.6 install on Centos 7.
After docker install, I installed portainer image. I can’t access portainer and I can’t ping the container IP address. I installed ubuntu/latest image and from that container, I can’t get out to Internet to update packages.
Something seems broken with my default bridge network and how containers access it.
On another similar configured system, everything just works.
How do I go about troubleshooting this?
