I am getting one weird issue while deploying Cluster on Kubernetes.
Some background details:
I have deployed Kubernetes Cluster using
kubeadm-1.10.5 on my on-prem hardware with
Master : Centos 7.3 Node1 : Centos 7.3 Node2 : Centos 7.3 Node3 : Centos 7.3 Node4 : RHEL 7.2 Kernal `3.10.0-327.el7.x86_64` Node5 : RHEL 7.3 Kernal `3.10.0-514.el7.x86_64`
Now everything works fine except on Node4. On this
node4 I have successfully deployed all the
kube-system pods and my application Pods, but the only issue which I am facing is any pod launched on
node4 is unable to access/ping any external IP address.
