LXC/LXD vs Docker

Proxmox supports LXC, TrueNAS supports kubernates. The difference between LXC and docker container is, the LXC runs full OS without kernel, docker container only runs application.

Docker vs Podman

Daemon

Podman has no daemon, which can run under normal user.

Docker has daemon dockerd running as root.

Unix socket

Docker uses Unix socket /var/run/docker.sock

All the REST API commands are implemented using this socket.

For example,


`docker version` command is implemented via following API.

curl --unix-socket /var/run/docker.sock http:/v2/version
