How to Build Images Faster
Explore methods to accelerate Docker image builds when developing Go applications. Learn to cache Go module dependencies locally and with Docker Compose, understand Docker's layer caching, and improve build times relevant for local and CI environments. This lesson helps you reduce resource use and wait times during development.
Go compiler is one of the fastest modern programming languages. However, it still takes quite a few seconds, sometimes even minutes, to actually build and run code. This isn't ideal in the fast-paced tech world, where changes are pushed and built multiple times in a day. If we can somehow speed up the build process, it would not only save the developers a lot of time but also save resources required to generate these builds.
Let's see how we can optimize the build process.
Caching dependencies
The build process of our coffeeshop app involves downloading the dependencies, building the Go executable, and then building a Docker image from it. So, which of these steps takes the majority of the build ...
