I want to use the resources of master node of kubernetes cluster for my application which will be launched.
How to use the master node as worker node in Kubernetes cluster?
I have two nodes setup. I can launch a job from master node which is running on worker node. But I dont want to waste my Master node resources.
As this link
First, get the name of the master
kubectl get nodes
NAME STATUS ROLES AGE VERSION
yasin Ready master 11d v1.13.4as we can see there is one node with the name of yasin and the role is master. If we want to use it as worker we should run
kubectl taint nodes yasin node-role.kubernetes.io/master-From here
By default, your cluster will not schedule pods on the master for security reasons. If you want to be able to schedule pods on the master, e.g. for a single-machine Kubernetes cluster for development, run:
kubectl taint nodes --all node-role.kubernetes.io/master-
