Code for DockerCon EU 2018

The code in this repo was used in a live demonstration talk for DockerCon EU 2018, titled "Programming the Cloud Using Containers as the Building Block".

In this talk, we construct an application consisting of a Redis instance and a Redis Commander instance. (Thanks to Joe Ferner for creating Redis Commander!)

The code in this repo is split into four subfolders, for easy navigation:

  • Step1: Contains the code for the "first" step of the DockerCon talk. This code is the "first step" code showcased in the talk, before any modifications were made. This code creates a Docker container for Redis, a Docker container for Redis Commander, and connects the two using a Network.

  • Step2: Contains the code for the "second" step of the DockerCon talk, where we introduce a Redis component resource that encapsulates the use of Docker containers.

  • Step3: Contains the code for the "third" step of the DockerCon talk, where we turn Redis into an abstract class and provide implementations of it for Docker and Kubernetes.

  • Step4: Contains the complete code for a package implementing a Redis component, suitable for publishing to NPM. This package includes some additional code that we did not have time to cover in the talk, most notably an Amazon implementation of the Redis abstraction using AWS ElastiCache.

All examples in this repo use Pulumi. You can download the Pulumi command-line tool from the official website. You can also check out the source code of Pulumi from the official repo.

Every step can be run by cd-ing into the code directory, creating a stack for the example, installing dependencies, and running pulumi up:

$ cd step1
$ pulumi stack init my-stack-name
$ npm install
$ pulumi up

At every step, the stack output host will point to a running Redis Commander instance on your local machine. You can access this service in a web browser by running open $(pulumi stack output host).

You can’t perform that action at this time.
