I wonder about leaving lxc using docker instead.
I have used privileged lxc containers for years. Currently I wanted to run unpriviledged lxc containers. Well, one lxc container with user mapping to my hostuser runs fine.
More than that one is making troubles I can’t solve so far and neither I got help, yet.
As far as I have read about docker, it depends on using root at least to start the application, or there is a real root (0:0) in the linux container - by design. Running unpriviledged seems possible but is no standard. - So I expect the same or other problem when doing so.
What do you think, can I have multiple unprivileged linux dockers with id-mappings to the hostuser?
