Hello!
I am new to lxc and just signed up to this mailing list.
As root I have created a lxc container and installed code-insiders to
run Visual Studio Code inside the container.
After reading an article I added the following lines to the containers
config and verified that the UID/GID match host user UID/GID:
# Container's UID/GID 0-65535 are mapped to host's 100000-165535,
# but UID/GID 1000 on the container is mapped to host's UID/GID 1000.
lxc.idmap = u 0 100000 1000
lxc.idmap = g 0 100000 1000
lxc.idmap = u 1000 1000 1
lxc.idmap = g 1000 1000 1
lxc.idmap = u 1001 101001 64535
lxc.idmap = g 1001 101001 64535
When I try as user with UID 1000 to start the container I get:
lxc-start -n VisualStudioCode -F
lxc-start: VisualStudioCode: tools/lxc_start.c: main: 214 You lack access to
/home/peter/.local/share/lxc
When I try as root to start the container I get:
lxc-start -n VisualStudioCode -F

information can be obtained by setting the --logfile and --logpriority options
I am running Debian Buster with lxc version 3.1.0.
Obviously I am doing something wrong in my configuration or how I use lxc.
Any help would be appreciated.
Best regards,
Peter Carlsson
