If EasyOS is specifically for containers, I do not see a container image at the LXC/LXD repository at https://us.images.linuxcontainers.org/

Even Kali Linux has a container image at https://us.images.linuxcontainers.org/

edit: If anyone at EasyOS wants to add a container image, see as an example the PR for Kali, https://github.com/lxc/distrobuilder/pull/179
