问题
In GKE, when we create nodes, there will be a master node and many worker nodes will be created. I have a doubt whether master node is the one among which we created(replicas mentioned) or GKE creates master node separately. And What is the topology(eg.,mesh,star) in which gke cluster is formed ?
回答1:
In GKE, if you create a standard cluster you will have API access to one master node, if you create regional cluster you will have three master node but you will access then in One endpoint (one in each zone of the region).
GKE is kubernetes managed cluster, The master node is not visible among your service node you can only access through the API only.
The default GKE confuguration (topology) see the below screen
Here some documentation regarding Private cluster
