OTP Test Codes

Sample OTP QR Codes

The following sample codes are not valid for the listed services but should allow basic testing of an authenticator application. Clicking on a QR code image will display just that code so it is easier to scan without interference from the other codes.

You can use this site to generate more QR codes as needed. It will also let you verify the produced codes against its own calculated code.

Deploying Elixir and Phoenix applications using Docker and Exrm

Goal

By the end of this quick guide, you will know how to compile a Phoenix app release using Exrm and run it inside a Docker container. I've found only a couple of articles that discuss getting an Elixir app up and running inside a Docker container, and even those only touched on some parts of the process. The idea is that this guide will give you a full end-to-end example of how to get all the pieces and parts working together so that you are able to deploy your Phoenix application inside a Docker container.

Assumptions

1. You already have a working Elixir environment with the Phoenix Framework installed
2. You have at least basic working knowledge of Docker, and have installed the Docker tools onto your local environment
