“Setting up remote server authentication” will never be on your job description. It’s not one of those desirable responsibilities that convinces talented people to move across the country and pursue the job of their dreams.

But at that dream job, you might be asked to set up an SSH key. You’d better be ready.

In this course, we will learn the fundamentals of creating SSH keys and configuring them for connectivity to a remote server. We’ll figure out how to:

- tunnel SSH connections for easier local debugging
- set up configuration files to simplify the aspect of connecting to remote servers
- use security features like blocking incoming connections

Being prepared is key. Learn the skills now!

Bash is a Unix shell and command language written by Brian Fox for the GNU Project as a free software replacement for the Bourne shell. Bash is a command processor that typically runs in a text window, where the user types commands that cause actions. Bash can also read and execute commands from a file, called a shell script.

SSH for Remote Server Authentication

In this course we will take a simple Node.js app that connects to a MongoDB database and uses an Express web server, and learn how to setup a full software development deployment process as well as how to properly “Dockerize” the app. 

We’ll step through setting up proper version control techniques, managing configuring within the environment, setting up proper build/deploy/run processes, and all with abiding by Docker best practices. We’ll also make sure our deployment is setup for scale, and have consistent development practices in place for reliable app deployments.

Docker containers wrap a piece of software in a complete filesystem that contains everything needed to run: code, runtime, system tools, system libraries – anything that can be installed on a server. This guarantees that the software will always run the same, regardless of its environment.

Docker Fundamentals

Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.

express

High availability apps require that no distinction be made between local and remote services. Attached resources should be accessed by environment variables, and in doing so allow you to swap out one attached resource for another. 

In this lesson we will setup a reverse proxy that directs image path requests and routes them through a defined server URL. By doing so, we decouple server requests for images which allows for easy switching from locally-served image assets to a CDN by simply updating an environment variable.

Proxy Requests for Local and Remote Service Parity

Docker containers are stateless by default. In order to persist filesystem changes, you must use docker volumes. In this lesson, we will go over how to copy files over to Docker containers, how to create volumes and copy data to them, and also how to mount remote folders for persisting updates.

Create Docker Volumes for Persistent Storage

In this lesson we will find out how to serve static assets (images, css, stylesheets, etc.) with Express. We will go over writing initial boilerplate for a simple Express app, and using Express's built-in middleware to serve these assets through a web server on Node.js.

Serve Static Files with Express

In this lesson we will cover proper version tagging when building Docker images, creating a docker-compose.yml file for proper release management, and running the tagged release by using Docker Compose to launch app resources as Docker containers.

Build, Release and Run Containers with Docker Compose

NGINX is a free, open-source, high-performance HTTP server and reverse proxy, as well as an IMAP/POP3 proxy server.

Learn about the concepts of managing data within Docker volumes, including all of the commands to create and manage volumes. We'll demonstrate how to mount a Docker volume to one or many containers by creating and mounting a volume to an Nginx proxy, and then verify the output with curl. You'll also see how changes to files within volumes of one container propagate to other containers with the same volume mounted, and learn various commands to inspect Docker volumes.

Manage Data within Docker Volumes

In this lesson we will cover how to build your own custom Docker image from scratch. We'll walk through the process of starting a Debian container, installing packages and working through configuration issues, as well as a strategy for building a Dockerfile.

Build Your Own Custom Docker Image

In this lesson, we will look at `docker container prune` to remove old docker containers. We can also use `docker system prune` to clean up any containers, images, volumes, and networks all in one command.

Prune Old Unused Docker Containers and Images

In this lesson, we'll find out the basics of running Docker containers. We'll go over how to download images from Docker Hub, what happens when you stop containers, how to restart a container once it's been stopped, and also how to remove containers.

Run, Stop and Remove Docker Containers

Learn how to build a simple Node.js web server with Docker. In this lesson, we'll create a Dockerfile for a simple Node.js script, copy and build it into a Docker image, and start a container to run the web server.

Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

node

Learn how to setup an Nginx proxy server that sits in front of a Node.js app. You can use a proxy to control the flow of frontend requests hitting your app, as well as to achieve better performance and scalability. We'll create a sample Node.js app and configure a default Nginx configuration file to proxy web requests.

Learn the benefits of running one-off, short-lived Docker containers. Short-Lived containers are useful to execute one-line commands or setup scheduled tasks. We'll demonstrate setting up a cronjob from the host machine to tap into the benefits of running automated, timed scripts with Docker.

Run Short-Lived Docker Containers

npm is the package manager for JavaScript. Find, share, and reuse packages of code from hundreds of thousands of developers — and assemble them in powerful new ways.

npm shrinkwrap > npm install > npm shrinkwrap is not guaranteed to produce the same output as just shrinkwrapping once, whereas Yarn explicitly uses "an install algorithm that is deterministic and reliable". We’ll learn how to generate a `yarn.lock` file and commit it to version control to ensure a deterministic and reliable module install process.

Pin Down NPM Package Versions with Yarn.lock

Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.

A reliable version control and source code tracking process is important for delivering apps with consistency and reliability. In this lesson, we will learn aspects of the Git Flow branching model which provide standards for developing and deploying apps with Git. We will walk through the methodologies of this well-known branching model, how to work with it from develop through to staging environments, and versioning your source code properly for production.

Use Git Flow as a Reliable Version Control Model

In this lesson we create a new Express web server app for handling file uploads and persisting them to the filesystem. We will walk through using the express-fileupload middleware module from npm to process file uploads, and then use the Express static middleware to serve the uploaded file as a static asset.

Upload Files with Express

React is one of the web’s most popular frameworks for building JavaScript applications. 

If you know what you’re doing, React can drastically simplify how you build, use, and maintain code.

Whether you’re a React newbie or you’re ready for advanced techniques, you can level-up with egghead. Explore our in-depth courses, lessons, and community resources to build more powerful applications and crack open your career.

Setting up tooling for a basic React app is typically very hard to do and requires a lot of configuration. In this lesson, we will setup a new React project with Neutrino with zero configuration. Neutrino uses Webpack and Babel behind the scenes, so you still get great build technology, but without all the heavy lifting of needing to configure it.

Bootstrap a Zero Configuration React App with Neutrino

Learn how to setup an Nginx proxy server with Docker that sits in front of a Node.js app. You can use a proxy to control the flow of frontend requests hitting your app, as well as to achieve better performance and scalability. We'll create a sample Node.js app, configure a default Nginx configuration file for proxying web requests, build both Node.js and Nginx Docker images, and learn how to link everything up and get it running with Docker specifics.

Storing configuration in files instead of the environment has many downsides, including mistakenly checking in the wrong configuration in the wrong environment, coupling configuration with code, and scaling issues in larger server architectures. 

We’ll learn how to update app code to look at environment variables for configuration values instead of using configuration files, and different approaches for managing environment variables between dev/stage/prod.

Manage Configuration Values with Environment Variables

webpack is a tool to build JavaScript modules in your application. To start using webpack from its cli or api, follow the Installation instructions. webpack simplifies your workflow by quickly constructing a dependency graph of your application and bundling them in the right order. webpack can be configured to customise optimisations to your code, to split vendor/css/js code for production, run a development server that hot-reloads your code without page refresh and many such cool features.
