Docker error while using rancher

[Alphvino]

So i was trying to install rancher via docker in a LXC container. The LXC is priviliged with nesting enabled but when i try to run the command needed for spawning rancher:

docker run -d --restart=unless-stopped \
-p 80:80 -p 443:443 \
-v /opt/rancher:/var/lib/rancher \
--privileged \
rancher/rancher:latest

it gives this error: docker: Error response from daemon: OCI runtime create failed: container_linux.go:380: starting container process caused: apply caps: operation not permitted: unknown.
This error is given also when i try to launch the docker hello-world container. Any ideas on how to fix this? I already tried using unpriviliged container with keyctl and nesting but then rancher won't spin up because he wants priviliged options

There are some extra steps for running docker in LXC. Tonnes of info on Google, e.g.: https://danthesalmon.com/running-docker-on-proxmox/

My Docker LXC contains these three lines at the bottom. Is yours the same?

/etc/pve/lxc/114.conf

lxc.apparmor.profile: unconfined
lxc.cgroup.devices.allow: a
lxc.cap.drop:

P.S. I don't think the Proxmox team support or recommend docker in LXC. It can be problematic and it's usually recommended to run a VM for docker instead (or better yet, run your apps directly as LXC containers )
