I'm following the procedure for mounting a host drive inside an lxc container as described here. In that article the author sets the raw.idmap like this:
lxc config set zesty raw.idmap 'both 1000 1000'
I want to customize the mapping for gid and uid as described in the lxd idmap documentation. Which shows a sample mapping as this:
both 1000 1000 uid 50-60 500-510 gid 10000-110000 10000-20000
I'm struggling with the syntax for actually setting this, as it doesn't seem as though the command in the first article works for multi-line configurations, and I've tried entering it all on a single line and by using JSON, but no luck, as the container gives configuration errors and won't start.
What is the correct way to configure this?
