About this event

Hello Seattle Kubernauts!

Please join us for the March Seattle K8s meetup.

Ashish will present recent activity in the cluster-api SIG related to the AWS provider.

Vinay and Peng will team up and present: "In-place Vertical Scaling for Kubernetes Pods." Currently, vertical scaling of Kubernetes pod CPU or memory resource allocations requires pod restarts. This is disruptive to services, and expensive for long-running applications/jobs. It is very important to have the ability to scale resources without pod restart.

In this talk, Vinay and Peng will present a design for restart-free scaling of pod resources, with pod restart as a policy-controlled choice rather than a necessity. They will illustrate a customer use case, a gene-sequencing application where pod restart is expensive. They will provide an overview of their implementation of vertical scaling of pod CPU/memory resources. They will discuss how they addressed some unique challenges such as multiple scheduler race conditions, talk about how failures are handled via retries, and conclude with a demo.

SPONSORED: Big thanks to NetApp, Sysdig and Tigera for their support!
