Kubernetes Pod status Pending

Problem

Kubernets pods status Pending

Cause

Unable to make k8s cluster up due to resources unavailability in the cluster (master/slave). Check RAM and cpu. In this case, cpu processor is 1 which leads to ContainerCreating and the Pod status is Pending.

Increase the capacity of cpu processor (~3 to 4).

Check if the firewall rule enabled for private ip's of k8s cluster to allow all TCP.
