I think so.
It is LXD + KVM, so way more and finer tune control on lxc instances. It can run OCI images as well, so for docker instances with only a few configs and no persistent storage, it is actually quite handy. For docker instances that need pretty complicated compose files, I just run docker inside an lxc for now, until I figure that out.
Side question, but where are you hearing this about incus?
I’m wrapping up 9 years of using proxmox and I have very specific reasons for switching to incus, but I this is the third time I’m fielding questions in the last month about incus.
