Prerequisites

kubectl access to a Kubernetes 1.4+ cluster

Install Helm (Mac OS)

brew install kubernetes-helm
helm init
helm repo update

Fork repo

https://github.com/lachie83/croc-hunter#fork-destination-box

Install Kube Lego chart

helm install stable/kube-lego --set config.LEGO_EMAIL=<valid-email>,config.LEGO_URL=https://acme-v01.api.letsencrypt.org/directory

Install Nginx ingress chart

helm install stable/nginx-ingress

Follow the notes from helm status to determine the external IP of the nginx-ingress service

Add a DNS entry with your provider and point it do the external IP

blah.test.com in A <nginx ingress svc external-IP>

or *.test.com in A <nginx ingress svc external-IP>

Update jenkins.values.yaml

Find and replace `jenkins.acs.az.estrado.io` with the DNS name provisioned above

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

watch kubectl get svc --namespace jenkins # wait for external ip
export JENKINS_IP=$(kubectl get svc jenkins-jenkins --namespace jenkins --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}")
export JENKINS_URL=http://${JENKINS_IP}:8080

kubectl get pods --namespace jenkins # wait for running
open ${JENKINS_URL}/login

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

Add credentials for private container registry (optional)

kubectl create secret docker-registry croc-hunter-secrets --docker-server=$DOCKER_SERVER --docker-username=$DOCKER_USERNAME --docker-password=$DOCKER_PASSWORD --docker-email=$DOCKER_EMAIL --namespace=croc-hunter

Reference to the secret name must also be added to the chart values.yaml or set on install.
