Lightning Talk: Paying Down Debt: Converting Kubernetes To Use Go "Workspaces"
Lightningat KubeCon + CloudNativeCon North America 2022 · on Tuesday, 2022-10-25· at 17:40· Grand Riverview Ballroom AB·
summary
Kubernetes replaces its decades-old GOPATH hacks with Go 1.18 workspaces by adding a go.work file, enabling multi-module builds and unifying 30 scattered go.mod files. The project rewrites its generator toolkit gengo and the modules-aware packages API to handle 13 codegen tools and about 33,000 lines of generated code. Conversions introduce 10–40x slowdowns in tooling, currently tracked across ~88 commits, with goal of landing the cleanup by Kubernetes 1.27.
