This is sample kubernetes installation for jenkins.

1. Jenkins installed on kubernetes
2. Ingress(traefik) to jenkins namespace
3. Secure connection (https) to your jenkins namespace using Let's Encrypt

   I am using k3s for testing this repo, as you know, k3s has built-in ingress (traefik), if you don't have ingress, please install first

1. Clone repo

git clone https://github.com/ludesdeveloper/jenkins-kubernetes-lets-encrypt.git

2. Change directory

cd jenkins-kubernetes-lets-encrypt

3. Create namespace

kubectl create namespace jenkins

4. Install operator dependencies

kubectl apply -f operator/

5. Install jenkins operator

helm repo add jenkinsci https://charts.jenkins.io
helm repo update

6. Jenkins objects

helm install jenkins-objects ./jenkins-objects -n jenkins

7. Create jenkins instance

chart=jenkinsci/jenkins
helm install jenkins -n jenkins -f jenkins-values.yaml $chart

8. Install ingress, please change with your ingress controller ip address

   I am using nip.io for dns

helm install ingress ./ingress --set nipIPAddress=111-111-111-111

9. Get jenkins password

jsonpath="{.data.jenkins-admin-password}"
secret=$(kubectl get secret -n jenkins jenkins -o jsonpath=$jsonpath)
echo $(echo $secret | base64 --decode)
