lxd_volume_container_attach resource

[jtopjian]

I can rebase when #38 is merged, if needed.

It's also possible to attach a volume to a profile, so I'll be working on lxd_volume_profile_attach next.

There we go. We have too many tests 😄

How does one set file permissions / ownership for attached volumes?
I've tried creating a volume from dir and zfs based pool, but root inside the container does not have write permissions.

Also the owner is:

drwxr-xr-x  2 nobody nogroup  2 Apr 18 20:36 attach-test

Yeah, this is unfortunately a whole other issue. There are quite a few open and closed issues about this on the LXD repo. I don't have links off-hand, but search for setfacl. I think the issue borders on what's under LXD's realm and not which is why there isn't a good solution yet. IMO, LXD should handle setting permissions on new volumes.

I've only tested this with the dir and btrfs backends and had to use setfacl for both. I'm sure ZFS has the same problems, but I'm not sure about LVM.

And this isn't specific to the volume/attach resources, either. Same thing happens when you define a device in a profile or container.
