On this meetup, we will walk you through creating a Jenkins X cluster on GKE, creating an application using a Jenkins X quickstart, pushing the application into a staging environment.


  • A GitHub account
  • Basic Linux cli knowledge
  • Basic Git knowledge
  • Basic VI knowledge

Further Reading


For this workshop we are going to use a Devops Playground sandbox VM to access GKE, but feel free to use your own GCP account if you'd prefer.

Option 1: Use the devops playground sandbox account

Use the DevOps playground sandbox account.

Option 2: Register for a GCP Trial account

Google offer a trial account with $300 of free credit. You will require a Credit / Debit card to sign up but this will not be charged. To sign up follow these instructions.

Launch Cloud Shell

Navigate to the Google Cloud Console. Once you have logged in, click on the Activate Cloud Shell button in the top right of the screen.

Activate Cloud Shell

This may take a few minutes if this is the first time you've launched cloudshell. Once complete, you should see the following terminal:

Cloud Shell Terminal

Download Dependencies

All of the required dependencies for this workshop will be downloaded & installed directly into Google Cloud Shell.

If you are using the Devops Playground sandbox account, you can skip this step.

curl -L | tar xzv
sudo mv jx /usr/local/bin

Check that the jx binary is correctly installed

jx --version
$ 2.0.500

0. Create a Github Access Token

Navigate to (,read:user,read:org,user:email,write:repo_hook,delete_repo), Give the token a name and save this somewhere safe. We will remove the token at the end of the workshop.

1. Create Cluster

Ensure you are logged in:

$ gcloud auth login

If you are using the shared project, if you don’t have enough credit:

$ gcloud config set project u8cel62va-gcp-sandpit-803790 

Create a new empty GKE cluster:

$ jx create cluster gke --skip-installation --skip-login -n <your name>


$ jx create cluster gke --skip-installation --skip-login -n user01
  • If you are prompted for the GKE project, select the u8cel62va-gcp-sandpit-803790
  • Select the zone that is nearest - I'd suggest one of the europe-west zones

We will default a number of options, to override this, use the --advanced flag when creating the cluster.

Defaulting to machine type: n1-standard-2
Defaulting to minimum number of nodes: 3
Defaulting to maxiumum number of nodes: 5
Defaulting use of preemptible VMs: No
Defaulting access to Google Cloud Storage / Google Container Registry: Yes
Defaulting enabling Cloud Build, Container Registry & Container Analysis API's: Yes
Defaulting enabling Kaniko for building container images: No

It can take around 5 minutes to create the cluster, once this has completed we can launch the jx boot process:

2. Install Jenkins X

jx boot

Configure your gitconfig file

? Please enter the name you wish to use with git:  Gareth Evans
? Please enter the email address you wish to use with git:

When prompted for the domain, select the default.

When prompted for the github credetials, enter your github username:

Creating a local Git user for GitHub server
? GitHub username: <my gh user>
To be able to create a repository on GitHub we need an API Token
Please click this URL,read:user,read:org,user:email,write:repo_hook,delete_repo

Then COPY the token and enter in into the form below:

? API Token: ****************************************

When prompted for the environment information, select the defaults.

3. Look under the Hood

Select the JX namespace

jx ns jx

4. What Just Happened?

  • Created a kubernetes cluster on GKE
  • Configured & Installed Jenkins X using GitOps
  • Create two environments (Staging & Production)
  • Using tektoncd for the pipeline execution engine
  • No Jenkins CI

5. Create an Application

Next we're going to use a quickstart to an application. To do this run the following:

jx create quickstart


Using Git provider GitHub at

Browse the pipeline log via:    jx get build logs garethjevans-test/gevans01-test/master
You can list the pipelines via: jx get pipelines
When the pipeline is complete:  jx get applications
For more help on available commands see:
Note that your first pipeline may take a few minutes to start while the necessary images get downloaded!

Watch the build logs

jx get build logs

If nothing is listed, try manually invoking the build with:

jx start pipeline

View the application

jx get applications


gevans01-test 0.0.2   1/1

What Just Happened?

  • Created a new source repository on GitHub
  • Used code generation to create a new project
  • Used language detection to select an appropriate buildpack for the project
  • Configured a PR & master pipeline for that project
  • Kicked off an initial master build
  • Automatically pushed the application into the staging environment

6. Make a change to the application

$ git checkout -b wip
$ vi main.go
$ git add main.go
$ git commit -m "feat: updated welcome message"
$ git push origin wip
$ jx create pr

Watch the build logs

jx get build logs

View Preview Environments

$ jx get preview

7. Useful commands

$ jx get environments
$ jx get pipelines
$ jx start pipeline
$ jx get build logs -w
$ jx get activity
$ jx create quickstart -l Go
$ jx get build logs -f <project-name>
$ jx get activity -f <project-name>
$ jx get applications
$ jx promote my-app --version 0.0.1 --env production

8. Cleanup

Delete the GKE cluster (the cluster-name is the user value you applied in the first step):

$ gcloud container clusters delete <cluster-name> --region europe-west1-b

Remove storage:

$ gsutil ls && gsutil -m rm -r gs://<cluster-name>-<bucket-name>

Remove service accounts:

$ gcloud iam service-accounts list && gcloud iam service-accounts delete <name>@<project>

Cleanup the local configuration:

$ rm -rvf ~/.jx

NOTE: You can also run the jx gc gke command to generate a script to clean up unused resources.

9. For More Information

The Jenkins-X team can be found on the Kubernetes slack channels, you can get your invite from, we are on the channels #jenkins-x-dev & #jenkins-x-user.

Alternatively, Oscar sends out a fantastic bi-weekly newsletter about Jenkins X containing tips, tricks and early insight to new features - please sign up at

You can’t perform that action at this time.
