Creating a Jenkins X Kubernetes cluster

You may prefer other cloud vendors or on-premises deployment. For this recipe, we will use GKE. See the Jenkins X documentation for other vendor instructions.

Let's perform the following steps to create your first Jenkins X Kubernetes cluster using jx:

Create a Kubernetes cluster with GKE using the jx command with the gke parameter as follows:

$ jx create cluster gke --skip-login

Select your Google Cloud project; in our example, devopscookbook.
Select us-central1-a when asked to pick a Google Cloud zone.
Select Static Jenkins Server and Jenkinsfiles as the installation type.
Enter your GitHub username:

Creating a local Git user for GitHub server
? GitHub username:

Enter your GitHub API token. Go to the GitHub Token page at https://github.com/settings/tokens/new?scopes=repo,read:user,read:org,user:email,write:repo_hook,delete_repo to get your API token:

Please click this URL and generate a token
https://github.com/settings/tokens/new?scopes=repo,read:user,read:org,user:email,write:repo_hook,delete_repo
Then COPY the token and enter it following:
? API Token:

By default, Jenkins X will set the ingress rules to use the magic DNS nip.io domain:

? Domain [? for help] (your_IP.nip.io)

Enter Yes to the following question:

? Do you wish to use GitHub as the pipelines Git server: (Y/n)

Select the GitHub organization where you want to create the environment repository; in our case, k8devopscookbook.

You will see a message similar to the following when your Deployment is successful:

Jenkins X installation completed successfully
