Enhancement request: low-latency containers

[stevef1uk]

Enhancement Description

• The ability to start up containers in milliseconds rather than seconds

• Responsible SIGs:

• ?

Justification/ Explanation: I was experimenting with Argo as a more portable option to AWS Step Functions and noticed that the time to execute an Argo workflow on Kubernetes is quite long. This could be due to the time Kubernetes takes to schedule & deploy a Pod to run a container, which is simply the next step in an Argo workflow.

I would like the ability to run containers on Kubernetes in milliseconds rather than seconds. I noticed in this link that the Scheduler has very different SLA expectations: kubernetes/kubernetes#3954

Hi @stevef1uk, issues in this repo are created after consultation with the SIG that should own the enhancement. In this case, in my opinion, please discuss with @kubernetes/sig-scheduling-feature-requests and/or @kubernetes/sig-scalability-feature-requests first before filing an enhancements issue.

Also, according to the guidelines governing on what is an enhancement, the above seems to be a performance improvement which is unlikely an enhancement.
