How to connect K8S to Triton Datacenter Elastic Docker?

[a-prokopyev-resume]

Hello,

Please let me know, what is the best method to connect remote Docker Engine to a K8S cluster?

For example, there is Triton Compose having Docker API to connect to it even from a general docker CLI.

Can K8S create, run and manage it containers in Triton private cloud?

May be via something like K8S -> CRI -> CRI-xxx like cri-dockerd -> Triton Docker API?

May be like described in another issue:
#106

I am using cri-dockerd as CRI for kubernetes. I have set --container-runtime=remote --container-runtime-endpoint=unix:///var/run/cri-dockerd.sock as flags for kubelet

But using IP network to the Triton cloud with a TCP port of its Docker API? Is it possible? Or may be there is a better method to connect them?

Thanks,
Alex

Probably have a look at https://github.com/TritonDataCenter/triton-kubernetes, seems that they already have a product ?

Hello again,

It seems triton-kubernetes is not alive and most likely is not exactly what I wanted to use.

My idea was just to connect to Triton Elastic Docker as a K8S runtime by using cri-dockerd if specifying a host:port for remote docker is supported by this K8S CRI plugin.

Benefits:

cri-dockerd is an alive and supported project
Triton Elastic Docker officially invites to manage it via general remote docker compatible socket/connection.

I think it would be very convenient.

Is it possible to specify remote docker host in cri-dockerd so that kubelet can be hosted on a different node than where actual docker runtime is running?

In such case:

• K8S node kubelet could run inside a very light VM or even LXD container
• Actual docker runtime could run on another SmartOS host (in Triton Elastic Docker private cloud) which is Illumos fork (even not a Linux OS)

Please read more details about docker API support in Triton:

This is not something that is supported, but maybe https://virtual-kubelet.io/ could be something for you?

https://github.com/virtual-kubelet/cri/blob/master/README.md - think it only supports containerd, but...
