Under Ubuntu, I created a Centos 8 LXD container:
lxc launch images:centos/8 centoscontainer
Then, I log into the container with lxc exec centoscontainer /bin/bash.
I'm root, and I can access network just fine:
# ping mirrorlist.centos.org

But when I try to use yum install, it fails, and I don't understand why:
# yum install -y java-1.8.0-openjdk-devel
CentOS Linux 8 - BaseOS 0.0 B/s | 0 B 05:59
Errors during downloading metadata for repository 'baseos':
- Curl error (7): Couldn't connect to server for http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=BaseOS&infra=stock [Failed to connect to mirrorlist.centos.org port 80: Connection timed out]
Error: Failed to download metadata for repo 'baseos': Cannot prepare internal mirrorlist: Curl error (7): Couldn't connect to server for http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=BaseOS&infra=stock [Failed to connect to mirrorlist.centos.org port 80: Connection timed out]
What is the way to troubleshoot this ?
