Microk8s Installation and Configure Dashboard

Microk8s is the most happening thing in Kubernetes World. Here I would like to share my exploration of microk8s. Earlier there was 'Minikube' which is targets to Developers community to reduce the operations.

Assumption

You know how to create a VM using Vagrant, VirtualBox

Microk8s installation on Ubuntu 

To install you should be super user on your Ubuntu VM sudo -i The snap is a package manager available in all Linux distributions. Here in the Ubuntu 18.04 validating is it available. Check snap package tool available

snap version

Now we all set, run the install the microk8s command here the --classic is must

snap install microk8s --classic --edge

Check the version

microk8s.kubectl version --short

Create an alias to simplify your command

alias k="microk8s.kubectl"

Let's use k now

k get nodes
k get nodes -o wide

# check the namespaces list
 k get namespaces
 k get all --all-namespaces

This might take couple of minutes on your laptop that is actually depends on your system capacity and speed. To start the microk8s Duplicate Terminal and try to run a pod. use same aliase here as well. alias k="microk8s.kubectl" on Vagrant user

   sudo usermod -a -G microk8s vagrant
   sudo chown -f -R vagrant ~/.kube

deployment expose k expose deploy nginx --port 80 --target-port 80 type ClusterIP which elinks not installed, so lets install it.

microk8s.start

Once it is installed microk8s we can validate it by inspect option

microk8s.inspect

If there any warnings suggestions goahead and do that. To get all the command options for microk8s

microk8s -h

To get the status of kubenetes cluster

microk8s.status

To get the dashboard

microk8s.enable dashboard dns metrics-server

kubectl get all --namespaces
microk8s kubectl get all -A

kubernetes.service get the ip access in the browser To get the password use admin as user

microk8s.config

To login with Token option on the dashboard need to get the token. microk8s.kubectl -n kube-system get secret |grep kubernetes-dashboard-token microk8s.kubectl -n kube-system describe secrets kubernetes-dashboard-token To terminate your kubernetes cluster on microk8s

microk8s.stop

Deployment to microk8s

microk8s.kubectl create deployment microbot --image=dontrebootme/microbot:v1
microk8s.kubectl scale deployment microbot --replicas=2
