# First install lxc and uidmap
sudo apt-get install lxc uidmap

# Check that your user has a uid and gid map defined in /etc/subuid and /etc/subgid
# (for unprivileged containers)

# Edit /etc/lxc/lxc-usernet and add
your-username veth lxcbr0 10
# Then create
~/.config/lxc
cp /etc/lxc/default.conf ~/.config/lxc/default.conf
# And append these two lines
lxc.id_map = u 0 100000 65536
lxc.id_map = g 0 100000 65536

lxc.network.link = lxcbr0
# Where 100000 65536 are the start/end subuids range in /etc/subuid and /etc/subgid for the chosen user

# Deiban specific: creating the container won't work unless we do (as root)

# Now create a container
lxc-create -t download -n my-container

# Start the container
lxc-start -n my-container -d

# Confirm container status
lxc-info -n my-container
lxc-ls -f

# Get container shell
lxc-attach -n my-container

# Stop the container
lxc-stop -n my-container

# Remove the container
lxc-destroy -n my-container
