Let's get minik8s and the Google Hipster demo app up with multipass on OSX!

minik8s.md

Download multipass at https://multipass.run/

Create an Ubuntu 18.04 VM

multipass launch --name k8s --mem 4g --disk 40g --cpus 3

Start it

multipass start k8s

Shell into it

multipass shell k8s

Install minik8s

sudo snap install microk8s --classic

Start minik8s

sudo microk8s.start

Enable DNS

sudo microk8s.enable dns

Enable Dashboard

sudo microk8s.enable dashboard

Get a token

token=$(microk8s.kubectl -n kube-system get secret | grep default-token | cut -d " " -f1)

Show the token

sudo microk8s.kubectl -n kube-system describe secret $token

Copy and paste this somewhere special on your host machine (~/.mytoken)

Create a dashboard user yaml file

nano dashboard-adminuser.yaml

Paste stuff into the yaml file

apiVersion: v1
kind: ServiceAccount
metadata:
  name: admin-user
  namespace: kube-system

Install kubectl

sudo snap install kubectl --classic

Edit the dashboard service

kubectl -n kube-system edit service kubernetes-dashboard

Replace ClusterIP with NodePort at the type key:

apiVersion: v1
...
  name: kubernetes-dashboard
  namespace: kube-system
  resourceVersion: "343478"
  selfLink: /api/v1/namespaces/kube-system/services/kubernetes-dashboard-head
  uid: 8e48f478-993d-11e7-87e0-901b0e532516
spec:
  clusterIP: 10.100.124.90
  externalTrafficPolicy: Cluster
  ports:
  - port: 443
    protocol: TCP
    targetPort: 8443
  selector:
    k8s-app: kubernetes-dashboard
  sessionAffinity: None
  type: ClusterIP <----- REPLACE THAT WITH NodePort
status:
  loadBalancer: {}

Check where the dashboard is exposed

kubectl -n kube-system get service kubernetes-dashboard
NAME                   CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
kubernetes-dashboard   10.100.124.90   <nodes>       443:31707/TCP   21h

Write down that port. Above it's 31707.

Get out of the shell

exit

Install kubectl locally

brew install kubectl

Get the kubeconfig into the local environment

multipass exec microk8s-vm -- /snap/bin/microk8s.config > kubeconfig

Edit bash profile to use the kubeconfig forever and ever

nano ~./bash_profile

Add export to the file

export KUBECONFIG=~/.kubeconfig

Load the file

source ~/.bash_profile

Look at the cluster

kubectl cluster-info

View the dashboard by going to a browser and loading https://192.168.64.2:30251/#!/login

Login using your token in ~/.my-token

Ok, now let's deploy the hipster app

git clone git@github.com:GoogleCloudPlatform/microservices-demo.git

Now we can deploy the hipster app on K8s

kubectl apply -f microservices-demo/release/kubernetes-manifests.yaml

Ok! Finally let's get the port we can browse on our host machine:

NAME                TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)        AGE
frontend-external   LoadBalancer   10.152.183.25   <pending>     80:32675/TCP   21m

Now you can open the hipster app on port 32675 (of the cluster-info IP address)
