Kubernetes Federation requires a kubernetes cluster as a pre-requisite.

Create VMs

Create two VMs - kubefed-1(master) and kubefed-1w(worker) with below config -

VCPUs4
Disk20 GB
RAM16 GB



Configure Kubernetes Cluster

Follow steps from below link to install a kubernetes cluster using kubeadm, comprising just two VMs created in above step -

https://wiki.onap.org/display/DW/Deploying+Kubernetes+Cluster+with+kubeadm

Steps before "Configuring SDN-C ONAP" stage need only be followed. Also, note that for Federation cluster, we are going to use kubenetes version - 1.8.6.

We are using kubefed version 1.8.6. Steps for installing specific version are added in the referred wiki page.

 

Verify below pods up and running after completing all steps -
