Link Extractor

Link Extractor app scrapes links from a given web page. This repository illustrates step by step approach to learn Docker.

This version of the workshop is designed to be used with Docker Desktop Community but should work just about anywhere you can install or run a Docker Engine, including Play With Docker.

It starts from running a very basic Python script and gradually leads to a multi-service container orchestration (AKA micro-service architecture).

No Python skills required This workshop uses a Python example but no Python expertise is assumed or required. Step 6 switches to Ruby, but again, no Ruby knowledge is required.

How to Use the Repository

There are multiple folders in this repo which correspond to steps in the workshop. These folders also correspond to git branches to make it easier to step through the workshop without getting lost in the folder structure.

Here's how the recommended way to run through the workshop:

1. Install Docker Desktop Community for Windows or Mac
   • If you cannot install Docker Desktop you can also use Play With Docker or if you have a Linux machine you can install and use Docker Engine.
   • Run docker version to verify you're up and running. You should get an output something like the following:

2. Run git checkout demo first to setup the repos
3. Next run git checkout step0 to start the workshop.
4. Proceed through the workshop steps (step0, step2, and step4). If you're not in an instructor-led workshop the README.md will guide you through the steps. Note: Not all steps are used in this workshop. We skip step1 and step3 in the class and we do not cover step5 and step6, but they all remain here as bonus steps.
