(this demo is based on the Multi-cluster Cloud-Native grpc (microservices) application demo

Step 1: Install Skupper

Public1 namespace:

kubectl apply -f public1-cluster/deployment-ms-a.yaml
skupper init

Private1 namespace

kubectl apply -f private1-cluster/deployment-ms-c.yaml
skupper init 

Step 2: Install Skupper enabling the console

Public2 namespace:

kubectl apply -f public2-cluster/deployment-ms-b.yaml
skupper init--enable-flow-collector --enable-console --console-user admin --console-password 1234 --console-auth internal

Step 3: Create tokens

Public1 namespace

skupper token create public1-token.yaml --uses 2

Public2 namespace

skupper token create public2-token.yaml

Step 4: Create the links to establish the VAN

Public2 namespace

skupper link create ~/public1-token.yaml

Private 1 namespace

skupper link create ~/public1-token.yaml 
skupper link create ~/public2-token.yaml

Step 5: Look at the link status

skupper link status 

skupper link status --show-incoming-links 

Step 6: Exposing services through Skupper

Public 1 namespace:

./public1-cluster/expose-deployments-a.sh

Public 2 namespace:

./public2-cluster/expose-deployments-b.sh

Private 1 namespace:

./private1-cluster/expose-deployments-c.sh

Step 7: Look at the status

skupper status

Step 8: Look at the console

Go to the link that shows "skupper status command" in the private namespace

Step 9: Check that it works

kubectl get service/frontend-external
/usr/bin/firefox --new-window  "http://$(kubectl get service frontend-external -o=jsonpath='{.spec.clusterIP}')/"

Step 10: Revoke access

Public 1 namespace

skupper revoke-access

Step 11: Debug events

skupper debug events

Step 12: Debug events in kubernetes

kubectl get events
