The repository is organized as follows:

• kube-system/: Contains manifests for resources in the kube-system namespace.
• production/: Contains manifests for the HTTPBin application in the production namespace.

1. Clone the repository:

$ git clone https://github.com/ronigarcia/kubernetes-test

$ cd kubernetes-test

2. Edit the kube-system/cluster-autoscaler/deployment.yaml and kube-system/cluster-autoscaler/serviceaccount.yaml with your environment information.

$ kubectl apply -f kube-system/cluster-autoscaler/* --context <kubernetes_cluster> --namespace kube-system

$ kubectl apply -f kube-system/metric-server/* --context <kubernetes_cluster> --namespace kube-system

$ kubectl apply -f kube-system/kube-state-metrics/* --context <kubernetes_cluster> --namespace kube-system

3. Deploying the HTTPBin Application in the production Namespace

To deploy the HTTPBin application in the production namespace, follow these steps:

$ kubectl create namespace production

$ kubectl apply -f production/application/* --context <kubernetes_cluster> --namespace production
