Introduction<\/strong><\/p>\n

Jenkins X is an open-source tool that automates CI\/CD workflow for cloud native apps on Kubernetes. It harnesses the power of Kubernetes and let its users use it without knowing internal working of Kubernetes. Jenkins X is a collection of some of the best of breed tools and microservices like Kubernetes<\/a>, Tekton<\/a>, Helm<\/a>, Lighthouse<\/a>, Terraform<\/a>, Octant(UI)<\/a>], Hashicorp Vault<\/a>, Kaniko<\/a>, Grafana<\/a>, Prometheus<\/a>, kuberhealthy<\/a>, etc.<\/p>\n

Create Jenkins X cluster git repo<\/strong><\/p>\n

Jenkins X provides a cluster git repository template for managing Jenkins X configuration. To change anything in your Jenkins X cluster, open a pull request to this repository. Fork this repository to your GitHub organization account by clicking on this link<\/a>.<\/p>\n

The recommended approach to install Jenkins X is via terraform script that is provided by another git repository. Fork this repository into your GitHub organization account via this link <\/a>.<\/p>\n

\"Jenkins<\/p>\n

Now clone this repository into your local and open the project via your favorite IDE.<\/p>\n

cd terraform-aws-eks-jx\/<\/em><\/p>\n

\nOpen outputs.tf<\/strong> file and modify below parameter<\/p>\n

vault_user_id:<\/em><\/p>\n

 <\/p>\n

*sensitive: true*<\/p>\n

\"Jenkins<\/p>\n

Also, open the variables.tf<\/strong> file and modify the following parameters: <\/p>\n

 <\/p>\n

cluster_name: <\/p>\n

  _default: \u201cmy-eks-cluster\u201d_<\/p>\n

profile:<\/p>\n

  _default: \u201cdefault\u201d_<\/p>\n

node_group_disk_size:<\/p>\n

  _default: \u201c20\u201d_<\/p>\n

vpc_name:<\/p>\n

  _default: \u201cmy-eks-vpc-stack-VPC\u201d_<\/p>\n

public_subnets:<\/p>\n

  _default: [“192.168.64.0\/18”, “192.168.0.0\/18”]_<\/p>\n

private_subnets:<\/p>\n

  _default: [“192.168.128.0\/18”, “192.168.192.0\/18”]_<\/p>\n

vpc_cidr_block:<\/p>\n

  _default: “192.168.0.0\/16″_<\/p>\n

is_jx2:<\/p>\n

  _default: false_<\/p>\n

jx_git_url:<\/p>\n

  _default: (your-cluster-git-repo(jx3-eks-vault)_<\/p>\n

jx_bot_username:<\/p>\n

  _default: (your-new-bot-user)_<\/p>\n

create_eks:<\/p>\n

  _default: false_<\/p>\n

create_vpc:<\/p>\n

  _default: false_<\/p>\n

vpc_id:
\n  _default: (vpc-id-of-eks-cluster)_<\/p>\n

nginx_chart_version:
\n  _default: \u201c3.12.0\u201d_<\/p>\n

Save GitHub bot user token as an environment variable<\/p>\n

export TF_VAR_jx_bot_token=<git-bot-user-token<\/em><\/p>\n

To initialize terraform<\/p>\n

terraform init<\/em><\/p>\n

To see potential changes made by Terraform<\/p>\n

terraform plan<\/em><\/p>\n

To execute the install<\/p>\n

terraform apply<\/em><\/p>\n

When prompted for provider.aws.region<\/strong>, enter the AWS region where your EKS cluster is provisioned.
\nIf the terraform apply command ran successfully then you will see similar output as below <\/p>\n

 <\/p>\n

\"Jenkins<\/p>\n

Note:<\/strong> It can take up to 10 minutes to install Jenkins X. <\/p>\n

To verify Jenkins X installation<\/p>\n

jx ns jx
\nkubectl get es -A<\/em><\/p>\n

Expected output:<\/p>\n

\"Jenkins<\/p>\n

\nCheck all pods are running in jx namespace<\/p>\n

kubectl get pods -n jx<\/em><\/p>\n

Expected output:<\/p>\n

\"Jenkins<\/p>\n

Another command to verify successful Jenkins X installation<\/p>\n

jx verify install<\/em><\/p>\n

Expected output:<\/p>\n

\"Jenkins<\/p>\n

\nTo visualize Jenkins X installation and pipelines on UI, run this command. It will automatically open UI in a browser<\/p>\n

jx ui<\/em><\/p>\n

Expected output: <\/p>\n

\"Jenkins<\/p>\n

Verify ingress is working. Replace <hook-jx\u2026> below with the value of hook\u2019s HOSTS.<\/p>\n

kubectl get ing -A
\ncurl -v http:\/\/<hook-jx\u2026>\/hook  <\/em><\/p>\n

Expected output:<\/p>\n

\"Jenkins<\/p>\n

Troubleshooting Tips:<\/strong><\/p>\n

TIP #1 <\/strong><\/p>\n

If _kubectl get es -A_ gives _404 status error_, it most likely means that the secret generation step in the boot log did not work. One way to re-generate secrets is by making a direct push to the main branch of the cluster git repo (not by creating a pull request).<\/p>\n

\"Jenkins<\/p>\n

 <\/p>\n

\"Jenkins<\/p>\n

\"Jenkins<\/p>\n

 To verify successful secret generation, check admin logs using the following command and select the latest log<\/p>\n

jx admin log<\/em><\/p>\n

Expected output:<\/p>\n

\"Jenkins<\/p>\n

TIP #2<\/strong><\/p>\n

If ingress controller is not working:  
\n <\/p>\n

curl -v http:\/\/<hook-jx\u2026>\/hook<\/em><\/p>\n

does not give a 200 status code then check your ingress controller pod (nexus-nexus-\u2026) is running via kubectl get pods -n jx <\/p>\n

\"Jenkins<\/p>\n

\nVerify this ingress IP is same as Elastic Network Interface (ENI) public IPv4 of the Network Load Balancer (NLB) created during Jenkins X installation. <\/p>\n

Conclusion<\/strong><\/p>\n

As you can see how easily we can tweak input variables as per our need in terraform script and run only one command *(terraform apply)* to create the entire Jenkins X cluster. Now we can import our application git repository to this Jenkins X cluster and can create multiple pipelines.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"
