Based on the topic i think the problem here is your cluster have not enough resources on your worker nodes, and a master node is tainted.

So the option here is either inreasing the resources on workers or taint the master node so You would be able to schedule pods there.

Control plane node isolation

By default, your cluster will not schedule pods on the control-plane node for security reasons. If you want to be able to schedule pods on the control-plane node, e.g. for a single-machine Kubernetes cluster for development, run:

kubectl taint nodes --all node-role.kubernetes.io/master-

This will remove the node-role.kubernetes.io/master taint from any nodes that have it, including the control-plane node, meaning that the scheduler will then be able to schedule pods everywhere
