sorry that I reopened this old discussion with my comment(s). People still seem to have strong opinions about how containers fit in their infrastructure. Didn’t mean to start a religious discussion about it.

To conclude from my side, I really like the overall direction Proxmox is taking in recent times (firewall, cloudinit, etc. But also the new backup server!). I think many people are using Proxmox as a lightweight private cloud these days. At least it prevents me from running a fat, complex OpenStack installation. I only wish the cloudinit support would be more complete (set userdata in the web interface, etc) and there was officially supported Terraform support.

Regarding containers: On any public cloud OCI/Docker containers run in VMs (alone for security reasons). So what Proxmox lacks a bit here is orchestration/management of that. I would wish for better support here (similar to the direction VMware is taking with their Kubernetes features), but I can understand if it’s out of scope.

But better cloudinit support would be really important imho so that Proxmox can at least fully serve a AWS EC2 like usecase and users can then run Kubernetes distros on top. Things are close, but not yet fully there.

That's exactly the thing, I would also love more cloud-init capabilities in terms of user-data directly setable in the WebUI as well as feature-parity with the cloud-init implementation in Openstack.

Reason: many KVM images with cloud-init support only work well using Openstack, with Cloudstack or any other KVM-based infra it's often a workaround-mess to get the same functionality.
