Pre-requisite:

1. You should have a machine with minimum 8 GB of RAM (10 GB recommended)
   1. 2 GB for master
   2. 2 GB for node1
   3. 2 GB for node 2
   4. 2 GB for virtual box and vagrant
   5. 2 GB for your machine
2. In my case I am running windows as host machine, You might be linux machine on which Vagrant should be up and running.

1. Download vagrant file from here and put it in a direcotry like Kubernates
2. Go to command line and “cd Kubernates”
3. Run the command “vagrant up” and wait until it gets completed
4. You should have all 3 machines up and running. Just to confirm run command “vagrant global-status”. It should show all 3 machines are running. The output might be something like:-

id       name        provider   state   directory

——————————————————————————

5d7b60e  k8s-master  virtualbox running C:/My-Kube-Machine/Kubernates

02cb68a  k8s-slave-1 virtualbox running C:/My-Kube-Machine/Kubernates

21ce8d2  k8s-slave-2 virtualbox running C:/My-Kube-Machine/Kubernates

5. Run command “vagrant ssh k8s-master”
6. Verify if the two command works without any error

Command1: kubectl get nodes

Command 2: kubectl get pods

If both commands are giving proper response like in below picture. You are good to go.

1. SSH into master node through vagrant ssh k8s-master
2. Install kubernates-dashboard. To install run the below command:

kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml

3. Now run the command “kubectl create serviceaccount dashboard -n default”

4. kubectl create clusterrolebinding dashboard-admin -n default --clusterrole=cluster-admin --serviceaccount=default:dashboard

5. To get the credentials in order to login to you kubernates dashboard. Run the command:-

   
   kubectl get secret $(kubectl get serviceaccount dashboard -o jsonpath="{.secrets[0].name}") -o jsonpath="{.data.token}" | base64 --decode 

6. Go to another window and ssh into master node and run the command

   kubectl proxy --address 192.168.33.60 --port=9999 --accept-hosts='^*$'

7. Now browse http://192.168.33.60:9999. This url is working now but its not showing dashboard yet.
8. To see the dashboard open the link

http://192.168.33.60:9999/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/#!/login

9. Enter the token from first window and use it for login and login it from there.
10. You might see permission problem on dashboard.. if you seen then run below command on master nodes

    kubectl create clusterrolebinding kubernetes-dashboard --clusterrole=cluster-admin --serviceaccount=kube-system:kubernetes-dashboard
