Pod Topology Spread Constraints is a convenient feature to control how pods are spread across your cluster among failure domains such as regions, zones, nodes, etc.

You can also choose the pod distribution (skew), what happens when the constraint is unfulfillable (schedule anyway vs don't) and the interaction with pod affinity and taints...

How hard could it be to debug a network issue where pod connections time out?

It could take weeks if you are (un)fortunate like Alex.

But Alex and his team didn't despair and found strength in adversity while learning several Kubernetes networking and kubespray lessons.

In this KubeFM episode, you'll follow their journey and learn:

• How a simple connection refused led to debugging the kernel syscalls...

Is sharing a cluster with multiple tenants worth it?

Should you share or have a single dedicated cluster per team?

In this KubeFM episode, Artem revisits his journey into Kubernetes multi-tenancy and discusses how the landscapes (and opinions) on multi-tenancy have changed over the years.

Here's what you will learn:

• The trade-offs of multi-tenancy and the tooling necessary to make it happen (e.g. vCluster, Argo CD, Kamaji, etc.)...

Structured Authentication Config is the most significant Kubernetes authentication system update in the last six years.

In this KubeFM episode, Maksim explains how this is going to affect you:

1. You can use multiple authentication providers simultaneously (e.g., Okta, Keycloak, GitLab) — no need for Dex.

2. You can change the configuration dynamically without restarting the API server...

Can you run databases on Kubernetes and survive to tell the story?

Or should you refrain from running stateful workloads as much as possible?

In this KubeFM episode, Steven argues that you should run databases on Kubernetes.

He also goes further and demonstrates how to build your custom operator to manage your database.

Listen to the episode and learn how:

• You can use Kubebuilder and the Operator Framework to build your operator...

Service meshes and the community's opinion of them have changed drastically over the years.

From being perceived as unnecessary, complicated and bloated, they matured into security and observability powerhouses (while still retaining much of their complexity).

In this KubeFM episode, William deep dives into the world of service meshes and explains a few of the technical choices and trade-offs of service meshes in simple terms...
