i guess you are referring to proxmox.
well there are a couple different ways on how to do id as you said urself. i guess it's sort of personal preference, security, how many resources u got etc.
- for each docker a dedicated vm -> good security -> high resource waste (ram) and ofc also more storage used due system images usually needing more space than the the average lxc image (also depending on your settings you do not have thin provisioning)
- for each docker a dedicated lxc -> lxc's are controversial security wise, also require to run priviliedged and you need to edit some cgroup2 stuff in the lxc config -> extremely light on resources (basically 0 overhead). so you got your docker containers nice and seperate, also can control backup jobs nice and easy, can restore or rollback one single app at a time. this ofc also applies to the vm.
- all containers in a vm -> no need to 'clone your template vm' everytime you wanna host a new service (no brainer tho). you only got one ip address for all docker services, you gotta play with ports a lot here. if one docker might have a exploit and breaks out, all others are compromised. poterial system fuckup or reboot brings down all your docker containers. hard planning on resources like storage, the storage of you vm might not be enough in the future. but since it's in a vm, good seperation from the host os (proxmox)

i personally run a mixture of dedicated lxc and dedicated vm for each docker

One VM does not limit you to a single IP. Are you saying storage is hard for the base VM or the docker containers? For me these are separate things.

well true, you can assign as many IPs to a vm as you want. i meant to say, you can only use e.g. port 80 once on that machine, so you gotta rebind all your services web ui's, different databased or whatever to different ports

Are you saying storage is hard for the base VM or the docker containers?

for the base VM, e.g. you create a VM with 10 gb storage, but it's not enough. you got extra work expanding it.
at a lxc you just click "add x gb" and done.

ofc storage and ip assignment are different things. never said sth else

For docker people, do you have a linux VM that runs and stores all docker containers? Or do you have multiple VMs (or maybe LXCs) and each one of those has a docker container inside?
