Welcome to the cluster networking demo repo!

There are two similar but seperate demos here in this repo:

1- K8S operator to automate Skupper networking between clusters - with all the fixins

2- Step by step process for exposing Dapr service invocation over the Skupper VAN

K8S operator sample

To run this sample ensure you have the following installed

• Docker
• KinD (Kubernetes in Docker)
• Powershell Core

Steps:

1. Stand up a Vault docker image to act as our shared secret store:

• Run the .\gitops\create_vault.ps1 script to create the image with a weak default password

2. Create at least 2 clusters

• Run the .\gitops\init.ps1 to register the two function calls in your session.
• To create a public cluster (i.e. a cluster that can be reached externally somehow) we will create a Cluster and add a NodePort to a pre-determined port mapped to the docker image.
• Note: in this example, we are using ports 30080 and 30081 but you can use whatever you have available as long as you pass them into your ClusterPool CRD later on
• run createcluster publiccluster @(30080,30081)
• Next create a private cluster (i.e. one that has no external access)
• run createcluster privatecluster
• Now you will have 2 clusters with FluxCD installed pointing to this repo.
• Once all is complete, connect to these clusters and run kubectl get clusterpools -A. The result should look like this:

NAMESPACE   NAME     CONNECTED CLUSTERS   LOCAL EXPOSED SERVICES   TOTAL EXPOSED SERVICES   STATE        HAS EXTERNAL ACCESS
vslive      vslive   1                    0                        0                        Registered   true

• Verify you have 2 clusters connected.
• run createcluster privatecluster2
• Once complete, rerun the above kubectl command and verify there are 3 clusters connected.

3. Tear down:

• Run kind delete cluster --name=publiccluster;kind delete cluster --name=privatecluster;kind delete cluster --name=privatecluster2; to reset your machine state
