GopherCon 2020: The Quest for the Fastest Deployment Time - L Körbes

When a developer changes a line of code, how long does it take for that code to run in their development cluster? L Körbes, an expert in Kubernetes development tooling, has seen the answers to that question vary between 1 second and… infinity. So how do you get your team’s code to stay on the 1 second side? In this talk, L will explore every avenue to make our “from code change to process running” benchmark faster, and show you whether to… • …cache your deps with Docker layers or go mod, • remove debugging data to make Go binaries smaller, • pre-populate your container with the compiler cache, • keep a container running, sync code diffs to it, and recompile in place, • re-compile in place when you have a lot of memory and CPU, • re-compile when a lack of memory and CPU make the Go compiler sad, • use trickery to make binaries even smaller, • or, one last trick… how each of these differ when using a local cluster versus a remote one. Expect an in-depth exploration with strategies and techniques you can put in practice to speed up your workflow for good!
