Improving zero downtime on Kubernetes
A few months ago, we began a piece of work on my last project setting out to accomplish two things:
Improve the speed of our release process
Allow us to run multiple versions of the application concurrently
These were two limitations of our initial deployment and release design and so in sharing this blog I am hoping the lessons learnt will be able to help you avoid the same issues.
Before jumping into the solution, I'll quickly describe our starting point.
Please note: This is a simplified view of the infrastructure, we'll only describe elements relevant to the zero downtime aspect of the solution.
