episode 4: Pod topology spread constraints might not be the best solution, with Martin Humlund Clausen


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.

It's a great and straightforward feature, so what could possibly go wrong?

In this episode of KubeFM, you will follow Martin and his team's journey in discovering and fixing a production incident (on a Friday afternoon) due to a misconfiguration.

You will also learn:

  • What are Pod Topology Spread Constraints, and how to use them?

  • How unfulfillable scheduling requirements could lead to un-schedulable pods.

  • How to detect and alert on unscheduled pods.

  • How to manage your team during an incident to keep them calm and focused.
