This script will create a Kubernetes master node with Kubeadm and install calico network plugin. Some other needed tools such as Docker, Kubectl and Helm will also be installed.
From the output of the script, you should see a command on how to join a node to the created Kubernets cluster. Note that this is an example, the token and cert-hash of your installation will be different, please copy & paste the command to somewhere, we will need it later.

You can now join any number of machines by running the following on each node as root: kubeadm join 10.12.5.104:6443 --token 1x62yf.60ys5p2iw13tx2t8 --discovery-token-ca-cert-hash sha256:f06628c7cee002b262e69f3f9efadf47bdec125e19606ebff743a3e514a8383b |

Sidecar Injection
The In the transition phase, the Istio sidecar injector policy is configured as "disabled" when installing Istio. So the sidecar injector will not inject the sidecar into pods by default. Add the sidecar`sidecar.istio.io/inject annotation annotation` with value true `true` to the pod template spec to enable injection.
Note: when all ONAP projects are ready for Istio integration, the Istio sidecar injector policy could be configured as "enabled", the annotaton in the pod wil not be necessary.
