Analyzing Go Build Times
Go is often praised for its fast build times. While they are pretty quick, they are slow enough that I spend a lot of time waiting for them, enough that it prompted me to go down the rabbit hole of thoroughly analyzing them. This post covers all aspects of what makes Go builds fast or slow. Throughout this blog, we will use Istio as an example of real-world codebase. For reference on its size:...
Building Docker Images Fast (by not using Docker)
This post follows the journey Istio has taken over the years to optimize our docker image builds. While there is some useful tips to take out of this, this is not intended to be a guide on how a project should build images - the steps taken here go far past the needs of a typical project, optimizing exclusively for speed (and fun) regardless of the complexity to maintain. For background, over the years Istio has consisted of ~10-20 docker images (many are for tests only) made up of ~10-15 Go binaries and various static files....
