Corda 5 Speaker Notes.md

Running Corda 5 with Local Kubernetes : Speaker Notes

Installing everything you'll need for this workshop

You'll need a few things:

• corda cli
• cordapp builder
• java 11
• docker desktop or another kubernetes cluster running tool (minukube, etc.)

brew install docker kubectl helm 

Make sure to set docker for mac's resources for this demo. Ideally 8GB CPU, and 12GB of Memory.

We'll start by adding the kubernetes dashboard to our cluster so we can actually see these apps

helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/
# deploy kubernetes dashboard 
helm install dashboard kubernetes-dashboard/kubernetes-dashboard -n kubernetes-dashboard --create-namespace


# to proxy traffic to kubernetes cluster and the local browser, run this in a separate terminal: 
kubectl proxy 

# visit the kubernetes dashboard 
http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:dashboard-kubernetes-dashboard:https/proxy/#/login

# download a kubernetes admin user config file 
# I've written an example one here 
wget https://gist.githubusercontent.com/davidawad/48f7873d843e966cb81f7f6cb4df5466/raw/d7094df6d7c7c65bcb50534025482121bf619a0d/service-account.yaml

# apply the config file to create an admin-user account in our kubernetes cluster 
kubectl apply -f service-account.yaml

# get the token for our dashboard 
kubectl describe serviceaccount admin-user -n kubernetes-dashboard

You'll see output like this:

Name:                admin-user
Namespace:           kubernetes-dashboard
Labels:              <none>
Annotations:         <none>
Image pull secrets:  <none>
Mountable secrets:   admin-user-token-bvthf
Tokens:              admin-user-token-bvthf # <-- this one 
Events:              <none>


# Get the string for the token and inject it into this command like so: 
kubectl describe secret admin-user-token-bvthf -n kubernetes-dashboard

You'll get output like this:

# That Massive token is your token to login to the dashboard! 

Setting up the cluster for the app to run

Now we have a couple of commands to run here

Step 1 : Building the Project

./gradlew clean build

Step 2 : Creating the Cordapp Artifact

cordapp-builder create --cpk contracts/build/libs/corda5-template-contracts-1.0-SNAPSHOT-cordapp.cpk --cpk workflows/build/libs/corda5-template-workflows-1.0-SNAPSHOT-cordapp.cpk -o template.cpb

Step 3: Configure the Network

corda-cli network config kubernetes template-network
corda-cli network deploy -n template-network -f c5cordapp-template.yaml -t 5.0.0-devpreview-rc07 > corda-k8s-network.yaml

Step 4: Starting Corda on Kubernetes

Now we can apply the kubernetes config file to our network

kubectl apply -f corda-k8s-network.yaml

Step 5: Examining the Network

You can examine the network on your machine by once again using corda-cli

corda-cli network status -n template-network
