I'm facing this such error in kubernetes( 0/1 nodes are available: 1 node(s) had taint {node.kubernetes.io/unreachable: }, that the pod didn't tolerate.). My application server is down. First, I just add one file in daemon set , due to memory allocation (we are having one node), all pods are failed to allocate and shows pending state and fully clashes (stays in pending condition).If I delete all deployments and I run any new deployments also its showing pending condition .Now please help to get sort it out this issue. I also tried the taint commands, also it doesn't work. As per my consent , can I create a node with existing cluster or revoke the instance? thanks in advance

You need to configure autoscaling (it doesn't work by default) for the cluster https://docs.aws.amazon.com/eks/latest/userguide/create-managed-node-group.html Or, you can manually change the desired size of the node group. Also, make sure that your deployment has relevant resources request for your nodes
