Kubernetes single node cluster with Minikube and Vagrant

The following Vagrantfile code(syntax is Ruby) is creating single node Kubernetes cluster with Minikube.

Copy above code and follow the following screenshots. Run the following commands in Terminal.

mkdir MinikubeVagrant

cd MinikubeVagrant

nano Vagrantfile

Paste the Vagrantfile content like below.

save Vagrantfile and run the following command to start virtual machine.

vagrant up

Creating Kubernetes Dashboard Proxy

After Vagrant is up, it means that Minikube is ready to use. So, connect with SSH to Vagrant machine and run the following code to start Kubernetes Dashboard Proxy.

kubectl proxy --address --port=8001 --accept-hosts '.*'

Connecting to Kubernetes Dashboard from Host machine

Click one of the following link to connect the Dashboard. Ta taaa 🙂!/login



Rest of the details are already mentioned in this blog link Kubernetes multi node cluster with Vagrant (included Kubernetes Dashboards, Grafana, Prometheus)

Node.js babel different usage transpiling to ES5 and Debugging

There are different usages of babel tool. I put a sample package.json file. Notice that there are scripts block which has different usages.

Creating Babel configuration file


  "presets": [
  "plugins": [
  "sourceMaps": true,
  "retainLines": true

Running with Babel-node

//If you have installed babel-cli package globally, run below code.
babel-node --presets=env --plugins=transform-runtime src


//If you have .babelrc config file, run below code without specifying inline arguments.
babel-node src


//If you have installed babel-cli package locally, run below code.
./node_modules/.bin/babel-node --presets=env --plugins=transform-runtime src

Running with Babel-register

node --require ./node_modules/babel-register src


node --require babel-register src/index.js

Github Connect with your SSH Public Key

If you are using git for your projects, you need to run some git commands such as clone, pull or push. So, let’s say that you want to clone one git project and if it is asking your username and password, you can create a SSH Public Key for your pc, after that you can paste it your github account so that you will never need to specify username and password.

You can follow below screenshot to create a SSH Public Key. After you create it, copy created SSH Public Key from terminal and paste it to GitHub SSH Keygen window like below.

Follow below screenshots to add your SSH Public Key in your GitHub account.
