Learn to create containerized applications, manage deployments across infrastructures, and prepare for advanced Kubernetes concepts.

Kubernetes Essentials

Kubernetes helps us deploy and manage containerized applications at scale. It abstracts the underlying infrastructure of applications, meaning it doesn’t matter if we deploy our applications to Amazon Web Services, Google Cloud, Linode, or our own on-premises datacenter.

In this module, we’ll learn what Kubernetes is,  why we need it,  how it's expected to change, and how we can use it to create containerized applications. By the end of this module, we will be ready to tackle more advanced concepts and take our Kubernetes skills to the next level.

Getting Started 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;
