I am Installing a standalone Kubernetes cluster (kubeadm version is 1.14) on RHEL 7.7 Operating System. I have a Load Balancer (Private LB with a private IP address) configured for my Kubernetes master node. When I issued the command
kubeadm init --apiserver-advertise-address=<IP Address of the LB>
I got the below error:
Unable to register node "master node name" with API Server. write tcp "IP address of masternode":<52444>--"IP address of LB":6443. Connection reset by peer.
If I issue only
kubeadm init, the command successfully initiates the cluster.
Also, If I use the DNS of the LB and try to create a multi-plane cluster (using controlPlaneEndpoint as DNS of the LB), that also works. Any idea on why it fails with the
Also, what if I use the method of creating a multi-plane cluster (controlPlaneEndpoint) but use the cluster that is built as a standalone cluster? (i.e., not adding any further master nodes). Will it cause any issues?
