Assumptions,

You have a working k8s cluster with the following enabled options:

Persistent Volume Provisioning works
External LBs work
TBS is installed

create a service account. This account allows jenkins to create containers in the kubernetes cluster.

Create the Service Account

kubectl apply -f scripts/rbac.yaml

Create the kubecontext file using the shell script in the script directory.

getcicd.sh

This should leave you with a KUBECONFIG file. `kpack-deploy-sa'

Jenkins Integration

Install Jenkins with bitnami helm

helm repo add bitnami https://charts.bitnami.com/bitnami

Download the helm chart ( we need to make a change)

helm pull bitnami/jenkins

Unzip the helm chart.

tar zxvf jenkins-8.0.4.tgz

in the templates/deployment.yaml add a service account fo the deployment.

serviceAccountName: kpack-deploy-sa

apply the helm chart from the top level jenkins folder

helm install jenkins .

Path the jenkins install to get an external load balancer.

kubectl patch svc jenkins -p '{"spec": {"type": "LoadBalancer"}}'

Get the jenkins credentials

  echo Password: $(kubectl get secret --namespace default jenkins -o jsonpath="{.data.jenkins-password}" | base64 --decode)

Configure Jenkins

Download the following plugins

Kubernetes
environment inject
Generic webhook triggers
ssh agent
Job DSL
Utility Step Plugins

Configure Kubernetes Plugin

Manage-Jenkins->Nodes and Clouds->Configure Clouds->

Kubernetes URL: https://kubernetes.default

Kubernetes Namspace: default

Websocket: checked

Jenkins URL: http://jenkins:80

Add a GIT credential

add your private key to access github as an SSH credential

Configure service account secret.

Build container requires k8s access for kpack.

kubectl create secret generic jenkins-sa --from-file=kubeconfig=kpack-deploy-sa

Configure seed job

Create a new Freestyle job, give the git url of the repository containing the seed job. Under Build steps choose a Process Job DSLs step.

Look for scripts on filesystem.

ci/jenkins/*.groovy

Run the job

The job may fail due to unapproved scripts.

Manage-Jenkins->In-Process-Script-Approval.

Approve all the scripts, there should be 3.
Rerun the job.

Install Argo.

kubectl create namespace argocd
kubectl apply -n argocd -f https://raw.githubusercontent.com/argoproj/argo-cd/stable/manifests/install.yaml
kubectl patch svc argocd-server -n argocd -p '{"spec": {"type": "LoadBalancer"}}'

Get the Password

kubectl -n argocd get secret argocd-initial-admin-secret -o jsonpath="{.data.password}" | base64 -d

Harbor

Configure webhook
