A question for the Kubernetes pros: Is it possible to prevent a COMPLETED Pod from being deleted? (Or at least delaying the deletion until I can read the Pod logs?)

In more detail: an app runs a job which creates a pod. The app needs to read logs but the pod is gone. Fixable?

Reduce your Kubernetes spend by running one cli command.

Fun fact - Postgres was originally written with half the code in C and half the code in Lisp.

What are the best technical docs out there?

I'll go first: Postgres.

More work on reducing Prometheus memory consumption - this time by deduping labels. Has anyone tried enabling this in production? What have you seen?

What do people think of CEL? (Common expression language.)

Have been playing around with it a little and was reading github.com/kubernetes/enh…

Wrong answers only this time: what's a Kubernetes fact people don't know?

Every node is authorized to list all other pods and nodes in the cluster. One compromised node can result in enumeration of all other pods and nodes in the cluster.

A pod in Kubernetes is a group of containers. A pod is also the name for a group of whales. Get it? Like Docker whales? 🐳📦

zamboni Sam Rose Natan Yellin Running DNS __in the cluster__ was ALWAYS meant to be an example of DNS integration, not a full solution. Like many such cases, there is nothing more durable than a quick hack.

IM(NS)HO, the way GKE does DNS offload to CloudDNS is _much_ better, especially for managed offerings.

Natan Yellin Most people? How to pronounce it.

Federico Paolinelli @[email protected] Andy Randall 🇺🇦 Michael Hausenblas Patrick Magee Natan Yellin What Andy Randall 🇺🇦 isn’t saying is that etcd was originally an access database on a Windows file server.

Andy Randall 🇺🇦 Patrick Magee Natan Yellin You are, as usual, correct. Indeed, early versions also included Klippy, a proactive AI based scheduler. I remember fondly Klippy asking “It looks like you’re trying to schedule a pod here, can I offfer you a node …”

Michael Hausenblas Patrick Magee Natan Yellin Had to be VB to quickly mock up the UI. Most people have forgotten that a pod spec was defined via a Windows dialog until we got yaml support in the 1.02 release.

Natan Yellin Workers used to be called Minions, most likely due to the influence of Salt; which was the original deployment mechanism.

Trivia: how does kubectl port-forward work?

How does kubectl really work?

You can trace any kubectl command to see what API calls it makes.

Here is a great post from Thomas Stringer on the technique. This is how I figured out which columns prints and how.
