Prerequisites

1. Install minikube and kubectl
2. Clone the repo

$ git clone [e-mail]:jamesma100/k8s-primer.git
$ cd k8s-primer/

Make sure you can see your image by running docker images.

Setup

1. Start up minikube

$ minikube start

2. Build local Docker image

$ cd app/
$ docker build -t simpleflask .

3. Point your shell to minikube's Docker daemon:

$ eval $(minikube -p minikube docker-env)

This is important! Otherwise minikube will pull images from its own Docker registry instead of your local.

4. Create a deployment

$ cd manifests/
$ kubectl create -f helloworld.yml

Verify your deployment exists and that 3 pods are running

$ kubectl get deployments
NAME          READY   UP-TO-DATE   AVAILABLE   AGE
hello-world   3/3     3            3           6s

$ kubectl get pods
NAME                           READY   STATUS    RESTARTS   AGE
hello-world-6ffb67d86d-4nkdb   1/1     Running   0          72s
hello-world-6ffb67d86d-8s6hj   1/1     Running   0          72s
hello-world-6ffb67d86d-stzlp   1/1     Running   0          72s

5. Stop your cluster

$ minikube stop
