[idea] Unikernel Runtime for Kubernetes

[gaocegege]

It will be interesting to implement a CRI-O-compatible runtime for unik or other unikernel solutions. Then we could investigate if we could use unikernel to serve serverless workload in Kubernetes.

如果用这个系统（或者任何系统）让 k8s 支持 Unikernel 应该也不能直接搞个 Pod, 因为你不能把 docker image 像是 pod 一样 run, 所以会有独特的 crd. 所以……这个 idea 我可以理解为写个 Unik crd 吗？

[xplorld]

以及 k8s 的 cri 现在不支持自定义，整个 kubelet (还是整个集群？）只能用一种 cri, 所以如果用 cri 来搞意味着不兼容 docker (?) 所以也说明了需要 crd 而不能用 pod

[gaocegege]

可以啊，CRI 就是为了支持 pod 才写的

[gaocegege]

支持自定义，通过 annotation，可以一个节点多个 cri

vm 怎么跑 docker image

[gaocegege]

kata, runv 是如何资词的，就可以继续如何资词

[gaocegege]

现在已经有 vm 的 cri 了，https://github.com/kata-containers/runtime

话说策策是不是该更新下这个 issue 了

I think we can keep it a open, I have two WIP projects k1s (a rust implementation compatible w/ k8s) and guguos (a library os for running relational database) that are related to this idea.

(Then the next comment shows up 2 years later w/ someone else implemented it ...
