A disposable K3S Kubernetes cluster is very useful when you’re doing some development or testing work. In addition, if you do decide to modify the default profile, you should create an additional profile without NFS mounts to assign to the containers that do not need access to NFS (see Option 2 for instructions on creating a new profile. Ot Skip to main content. I try to delete the default profile and only keep my own profile but it just doesn' work that way. The following two examples shows that regardless if LVM is managed by lxd internal/external tools, removing the storage remove the volumegroup. Privileged containers are containers that are created by root and run as root. lxc profile edit <new profile) I managed to “somehow” overcome the problem, but in a highly unsatisfactory way: completely remove all lxd snap; compile from sources (including hand-installing a recent version of go); incur in the same problem discussed here; Apply solution (boot with systemd. It wouldn’t surprise me, since NFS is dependent on the kernel. If you have the snap version and deb version installed , remove the deb version to allow the snap version to take over.
