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 |

Then open your browser at http://tracing_node_ip:tracing_node_port/, you should see something similar to the following:
Note
- Tracing_node_port can be found by 'kubctl get svc -n istio-system'.
- ONAP microservices need to propagate the appropriate HTTP headers so that when the proxies send span information, the spans can be correlated correctly into a single trace.
Service Graph
Istio provides a Servicegraph service which generates and visualizes graph representations of the services in the mesh.
Open your browser at http://node_ip:30088/dotviz or http://node_ip:30088/force/forcegraph.html, you should see the service graph:
