But this ip will not persistent, so I have to run dhclient
to get the ip
To stop
the container (Ubuntu 16.04), I need to run with --force
options. Not need the option for other container. I have tried to delete and created container with Ubuntu 16.04 several times, but still cannot getting ipv4
My ufw
is inactive. I have run LXD for 3 years, but I forgot if I ever created Ubuntu 16.04 container and got the same problem. But Iām sure that the container that I created, will get ipv4.
Is Ubuntu 16.04 image have the problem? How to get ip and dns right on the image?
Thanks in advanced
