Multiple Apps have status "TaintToleration" when listing the pods, what does this mean and does it require action?

[Mannekino]

Hi,

When I run k3s kubectl get pods --all-namespaces I see multiple Apps (or pods if that is the correct term) with status "TaintToleration". What does this mean? Is this bad? Does it require action? How can I prevent this from happening? I only have a single App running at the moment which is Tautulli from TrueCharts.

Code:

# k3s kubectl get pods --all-namespaces

Taints and Tolerations

Node affinity is a property of Pods that attracts them to a set of nodes (either as a preference or a hard requirement). Taints are the opposite -- they allow a node to repel a set of pods. Tolerations are applied to pods. Tolerations allow the scheduler to schedule pods with matching taints...

kubernetes.io

No need to worry. This just means these apps are aware they can be evicted.

I don't like squatters, can I evict them forcefully or does Kubernetes law prevent me from doing so?

 

[Samuel Tai]

It should be possible to evict them. From the descriptions, they appear to be older versions of other running pods.
