Webservice-operator

Webservice-operator is an operator for deploying a webservice on Kubernetes with TLS encrypted external NGINX ingress controller.

Features

Webservice-operator is doing the following steps:

• Create a certificate with issuer .spec.issuer and for hostname .spec.host
• Create a deployment with replicas .spec.replicas, with resources .spec.resources and with a container from image .spec.image and listen on port .spec.containerPort the default port is 80
• Create a service where the deployment is available
• Create an ingress controller which is using the service as backend, using the certificate and listening on hostname .spec.host

Install

Prerequisites

Change the .spec.acme.email in the samples configuration files: letsencrypt_production.yaml and letsencrypt_staging.yaml, before applying them to your cluster.

1. Install NGINX Ingress Controller

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.0.4/deploy/static/provider/cloud/deploy.yaml
#use this deployment if you have kind cluster
#more info: https://kind.sigs.k8s.io/docs/user/ingress/
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/kind/deploy.yaml

1. Install cert-manager

kubectl apply -f https://github.com/jetstack/cert-manager/releases/download/v1.6.0/cert-manager.yaml

1. Add Issuer to the cluster

#Let's Encrypt stating environment, good for testing
kubectl apply -f config/samples/letsencrypt_staging.yaml
#Let's Encrypt production environment, the generated cert will be accepted by the browsers
kubectl apply -f config/samples/letsencrypt_production.yaml

Operator

1. Set KUBECONFIG pointing towards your cluster

2. Deploy the operator in the webservice-operator-system namespace to your cluster

make deploy

1. Change the sample configuration file: webservice_v1_webapp.yaml and applying it to your cluster

kubectl apply -f config/samples/webservice_v1_webapp.yaml
