Kubernetes Error 1 node s had taints that the pod didn t tolerate [closed]

Question

I'm trying to create a Kubernetes cluster. When I try to describe one of my pods, I get the following error:

1 node(s) had taints that the pod didn't tolerate.

Why am I getting this error?

Answer 1

Hey @Sitara, check if all your pods are in running state. If they are not then the possible reason for this error could that worker nodes aren't connected and the master node is unable to take the pressure.

For further details, refer to the Kubernetes course.

What if they are on-premises cluster, and also a single-node cluster.

Hi@Poornima,

The concept of taint has some context in Kubernetes Cluster. If you have a single node cluster, then it can work as a master node as well as a worker node. But if the node tainted, then you can't launch a pod on that node. I mean you can launch but the state of the pod will always remain pending. At that time the master node can't work as a worker node. So you have to remove the taint from your node.
