Creating a Kubernetes Cluster with Jenkins X and Importing App

If you kept the cluster from the previous chapter, you can skip this section. Otherwise, we’ll need to create a new Jenkins X cluster.

🔍 All the commands from this chapter are available in the 14-upgrade.sh Gist.

Create a new cluster and install Jenkins X#

For your convenience, the Gists from the previous chapter are available below as well.

GKE#

EKS#

AKS#

Install Jenkins X in an existing serverless cluster#

Use an existing serverless cluster: install-serverless.sh

• Create a new static GKE cluster: gke-jx.sh
• Create a new serverless GKE cluster: gke-jx-serverless.sh
• Create a new static EKS cluster: eks-jx.sh
• Create a new serverless EKS cluster: eks-jx-serverless.sh
• Create a new static AKS cluster: aks-jx.sh
• Create a new serverless AKS cluster: aks-jx-serverless.sh
• Use an existing static cluster: install.sh
• Use an existing serverless cluster: install-serverless.sh

Importing the application#

🔍 The commands that follow will reset your go-demo-6 master branch with the contents of the branch that contain all the changes we did so far. Please execute them only if you are unsure whether you did all the exercises correctly.

⚠️ Depending on whether you’re using static or serverless Jenkins X flavor, we’ll need to restore one branch or the other. The commands that follow will restore extension-model-jx if you are using static Jenkins X, or extension-model-cd if you prefer the serverless flavor.

🔍 If you destroyed the cluster at the end of the previous chapter, you’ll need to import the go-demo-6 application again. Please execute the commands that follow only if you created a new cluster specifically for the exercises from this chapter.

Now we are ready to talk about validating upgrades and backing up clusters.
