Kubernetes 1.27: updates on speeding up Pod startup

=> ↺ Kubernetes 1.27: updates on speeding up Pod startup

How can Pod start-up be accelerated on nodes in large clusters? This is a common issue that cluster administrators may face.

This blog post focuses on methods to speed up pod start-up from the kubelet side. It does not involve the creation time of pods by controller-manager through kube-apiserver, nor does it include scheduling time for pods or webhooks executed on it.

We have mentioned some important factors here to consider from the kubelet's perspective, but this is not an exhaustive list. As Kubernetes v1.27 is released, this blog highlights significant changes in v1.27 that aid in speeding up pod start-up.

Pulling images always takes some time and what's worse is that image pulls are done serially by default. In other words, kubelet will send only one image pull request to the image service at a time. Other image pull requests have to wait until the one being processed is complete.

Although Docker and Kubernetes are often used together, the two serve different roles in IT environments -- and Docker containers aren't the only option for Kubernetes deployments.
