## USING KIND TO TEST LOCAL K8S DEPLOYMENTS
- [Install KIND](https://kind.sigs.k8s.io/)
- Download and install helm 3 from https://github.com/helm/helm/releases
- wget latest archive and extract and store it under /usr/local/bin/
### Add Jenkins helm chart repo
- `helm repo add jenkins https://charts.jenkins.io`
### Install Jenkins using helm chart
- `helm install jenkins jenkins/jenkins`
### Accessing Jenkins
1. Get your 'admin' user password by running:
`kubectl exec --namespace jenkins -it svc/jenkins -c jenkins -- /bin/cat /run/secrets/chart-admin-password && echo`
2. Get the Jenkins URL to visit by running these commands in the same shell:
echo http://127.0.0.1:8080
kubectl --namespace jenkins port-forward svc/jenkins 8080:8080
3. Login with the password from step 1 and the username: admin
4. Configure security realm and authorization strategy

### Testing Local Application
- Configure and start KIND with a local registry by using [this script](https://kind.sigs.k8s.io/docs/user/local-registry/).
- Build your application image and tag it and push it to the local registry.
- Build a Jenkins job for your application using a Jenkinsfile.
- Configure the cluster to deploy to in the Jenkinsfile to the localhost KIND cluster

sh 'kubectl config use-context lc-jenkins'
sh "helm upgrade -i --debug {service name} {application chart} --version {chart version} --namespace {application namespace} -f {path to yaml file with custom values}"
