Query Node automated deployment

Deploys a Joystream node network on EKS Kubernetes cluster

Deploying the App

To deploy your infrastructure, follow the below steps.

Prerequisites

1. Install Pulumi
2. Install Node.js
3. Install a package manager for Node.js, such as npm or Yarn.
4. Configure AWS Credentials
5. Optional (for debugging): Install kubectl

Steps

After cloning this repo, from this working directory, run these commands:

1. Install the required Node.js packages:

This installs the dependent packages needed for our Pulumi program.

   $ npm install

1. Create a new stack, which is an isolated deployment target for this example:

This will initialize the Pulumi program in TypeScript.

   $ pulumi stack init

1. Set the required configuration variables in Pulumi.<stack>.yaml

   $ pulumi config set-all --plaintext aws:region=us-east-1 --plaintext aws:profile=joystream-user \
   --plaintext numberOfValidators=2 --plaintext isMinikube=true --plaintext networkSuffix=8122
   

If you want to build the stack on AWS set the isMinikube config to false

   $ pulumi config set isMinikube false

1. Stand up the Kubernetes cluster:

Running pulumi up -y will deploy the EKS cluster. Note, provisioning a new EKS cluster takes between 10-15 minutes.

1. Once the stack is up and running, we will modify the Caddy config to get SSL certificate for the load balancer for AWS

Modify the config variable isLoadBalancerReady

   $ pulumi config set isLoadBalancerReady true

Run pulumi up -y to update the Caddy config

1. You can now access the endpoints using pulumi stack output endpoint1 or pulumi stack output endpoint2

The ws-rpc endpoint is https://<ENDPOINT>/ws-rpc and http-rpc endpoint is https://<ENDPOINT>/http-rpc

1. Access the Kubernetes Cluster using kubectl

To access your new Kubernetes cluster using kubectl, we need to set up the kubeconfig file and download kubectl. We can leverage the Pulumi stack output in the CLI, as Pulumi facilitates exporting these objects for us.

   $ pulumi stack output kubeconfig --show-secrets > kubeconfig
   $ export KUBECONFIG=$PWD/kubeconfig
   $ kubectl get nodes

We can also use the stack output to query the cluster for our newly created Deployment:

   $ kubectl get deployment $(pulumi stack output deploymentName) --namespace=$(pulumi stack output namespaceName)
   $ kubectl get service $(pulumi stack output serviceName) --namespace=$(pulumi stack output namespaceName)

To get logs

   $ kubectl config set-context --current --namespace=$(pulumi stack output namespaceName)
   $ kubectl get pods
   $ kubectl logs <PODNAME> --all-containers

To see complete pulumi stack output

   $ pulumi stack output

To execute a command

   $ kubectl exec --stdin --tty <PODNAME> -c colossus -- /bin/bash

1. Once you've finished experimenting, tear down your stack's resources by destroying and removing it:

   $ pulumi destroy --yes
   $ pulumi stack rm --yes
