I am working with LXC containers and I am attempting to setup a network configuration but I cannot locate the configuration file. Every piece of documentation or answered question has been for older outdated versions of LXC.
Much of the documentation I found refers to a folder in /var/lib/lxc, but that folder does not exist. Documentation also refers to commands such as "lxc-create" which also do not exist.
I am using LXD to manage my containers instead of libvirt, if that makes a difference.
I guess you are talking about the 'old' LXC containers. In case you are running Ubuntu 16.04 or Ubuntu 16.10, everything is located in the /var/lib/lxd folder, also the commands changed.
To get a list of the available commands, execute lxc help --all and for deeper information lxc manpage. Here you can find additional useful information about the "newer" LXD system containers in Ubuntu :
Linux Containers - LXD
LXD doc / configuration
The LXD 2.0 Story series
If you installed LXC/LXD using "snap", try looking in the folder
/var/snap/lxd
That's where I found them all on my Ubuntu 20.04 LTS install when I was looking for them.
In case you are using multiple locations I find an easy way is
lxc storage list
which shows the path to each storage pool
