Kubernetes helps deploy and manage containerized applications at scale. It abstracts the underlying infrastructure, so it doesn’t matter if you’re deploying your applications to Amazon Web Services, Google Cloud, Linode, or your own on-premises data center.

In this course, you’ll learn why we have Kubernetes, what it is, where it’s going, and how to create containerized applications. By the end of this course, you’ll be ready to tackle more advanced concepts and take your Kubernetes skills to the next level.

Quick Start with Kubernetes

FROM node:current-slim

LABEL MAINTAINER=nigelpoulton@hotmail.com

# Copy source code to /src inside container
COPY . /src

# Set working directory
WORKDIR /src

# Install app and dependencies into /src inside container
RUN npm install

# Document the port the app listens on
EXPOSE 8080

# Run this command (starts the app) when the container starts
CMD ["node", "./app.js"]

// Simple node.js web app for demonstrating containerizing apps
// For quick demo purposes only (maintained approx annually)
'use strict';

var express = require('express'),
    app = express();

app.set('views', 'views');
app.set('view engine', 'pug');

app.get('/', function(req, res) {
    res.render('home.pug', {
  });
});

app.listen(8080);
module.exports.getApp = app;
