Automated Canary Deployments with HashiCorp Consul - Nic Jackson & Erik Veld - NDC London 2022

Releasing new software always carries an element of risk, no matter how many unit tests, functional tests, integration tests, manual tests, and any other kind of guard rails that you can think of. Until the application is deployed into the production environment and receives real-world traffic, you can not be 100% certain that the release is bug-free. The reason for this is mainly due to environmental changes that are difficult if not impossible to simulate. It is possible to write a conference talk titled “101 reasons why my application was fine in test, but broken in production”. The solution to this problem is that you should not do a big bang release of your applications, but release them gradually while monitoring the status, a pattern commonly known as Canary deployment. In this talk, we will show how modern tooling and specifically HashiCorp Consul enables this by automating away many of the previously required manual steps. We will walk you through the pattern, its caveats, and benefits, before showing you step by step how to enable this for your own applications.
