Application Container Roadmap

[trystan]

With the shift to application container runtimes (rkt, runc, containerd, etc) and their standardization with OCI, I'm wondering if Proxmox has a path to any registry/image based application deployment.

LXC is great for an entire machine, but I question the decision to run LXC containers for single apps as well as the decision to mount LXC containers on remotely/locally mounted loop devices considering Canonical and Docker advise against using mounted loops in production:
https://lxd.readthedocs.io/en/latest/storage/
https://docs.docker.com/storage/storagedriver/device-mapper-driver/

I really enjoy Proxmox as a platform, but the application container piece and container storage implementation I hope are at least being looked at.

This has been discussed a lot: Proxmox VE is a IaaS and you need to run containers in a datacenter manner on a PaaS, so this will not work conceptually directly on PVE, so you need to bootstrap your own PaaS infrastructure on your IaaS cluster, e.g. with docker swam, kubernetes or some other orchestration tool.

Considering the current advice is to run docker/application containers inside KVM and that defeats the performance reasons for running application containers to begin with, I don't see where the Proxmox infrastructure fits in for future deployments.

I'm hopeful that Proxmox will reconsider their stance on baking in at least some form of application container management be it in the form of k8s or some other orchestration engine.

IMHO this statement is simply wrong. Running docker inside VM is the way to go. That makes management much simpler and works great.

Agreed.
Look at amazon,google cloud,... They are running kubernetes/docker on top on vms.

@trystan
BTW, if you look at a nice kubernetes management platform, look at https://rancher.com/.

I just released my first beta in a "works for me"[tm] state for integrating Proxmox VE into docker machine deployments:

Hope to get a lot of feedback
