Kubectl Tip #1

A weekly kubectl command you might find useful

cycling all pods in a kubernetes namespace or the whole cluster

I’m starting this blog series where I’ll be sharing some occasionally useful kubectl commands. I hope you find a few tips handy.

The Command

This one liner cycles every deployment in a namespace.

Why would you do this?

You might want to get all new processes to pick up a new DNS endpoint. Maybe you switched out your CNI and need to recreate all pods. Perhaps your database was updated and your apps have stale connections. Rarely used, but useful when required.

You could also use the -A flag to cycle all namespaces.
