Deployment Template

Deployment template is a tool that quickly sets up CI/CD integration with your Kubernetes cluster.

Prerequisites

• Install kubectl cli
• Provision a Kubernetes cluster
• Install helm cli
• Create access tokens for git repository and container registry

Deploy Jenkins onto Cluster

1. Create a namespace to deploy your Jenkins release to

kubectl create namespace jenkins

2. Provision a persistent volume resource and a persistent volume claim resource so that the Jenkins service can have persistent data.

kubectl apply -f pv-volume.yaml

3. Provision the persistent volume claim for Jenkins

kubectl apply -f pv-claim.yaml 

4. Using helm and the values file in jeknins/values.yaml, deploy a release of the Jenkins chart onto your cluster

helm install jenkins stable/jenkins -f values.yaml --namespace jenkins

5. Access the Jenkins UI

. helpers/jenkins-ui.sh 

Redeploy

helm upgrade jenkins stable/jenkins -f values.yaml  --atomic --timeout 1m45s --install --namespace jenkins

Set up Secrets and Config

1. Add Git repo access token

kubectl apply -f git-credentials.yaml

2. Add container registry access token

kubectl apply -f cr-credentials.yaml

3. Add container registry configuration

kubectl apply -f cr-configmap.yaml

Deploy Kubernetes Dashboard (Optional)

1. Deploy the Kubernetes dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0/aio/deploy/recommended.yaml

2. Deploy the secrets required to access the dashboard

kubectl apply -f dashboard-adminuser.yaml

3. Access dashboard

. helpers/dashboard-ui.sh

• add git credentials as secrets
• add icr credentials as secrets
• k apply -f jenkins/icr-configmap.yaml

k --namespace dev create secret docker-registry container-registry --docker-server=us.icr.io --docker-username=iamapikey --docker-password=<apikey> --docker-email=a@b.c

Copy secret from one namespace to another

kubectl get secret <secret_name> --namespace=default --export -o yaml |\
   kubectl apply --namespace=<new_namespace> -f -
