Now that I set up an LXD container, how do I backup and restore LXD containers running on Ubuntu/Debian or Fedora/CentOS Linux server?
I have two LXD containers running. One is for Nginx, and another is for processing data. I need to share data between two containers. How do I add or mount a shared directory between two?
I need to save the state of my existing app running on LXD before I push new Python-based app. How do I create snapshots with lxc command for LXD based Linux container?
I run my app inside Ubuntu Linux 16.04 LTS lxd Linux container. To upgrade Ubuntu 16.04 to 18.04 LTS container, I run do-release-upgrade command, but I am getting the error message that read as “Must be connected to a terminal.” How do I fix this problem to upgrade from Ubuntu Linux 16.04 to 18.04 image?
