CI/CD for a Go Shop: Module and Build Caching Done Right

Go builds are fast - so the wins come from caching the module and build cache and paying less per minute.

A Go shop has quick compiles but frequent runs. The leverage is module/build caching, test parallelism, and a lower per-minute rate.

Cache module and build cache

Cache the Go module cache and build cache so repeated builds reuse compiled artifacts.

Parallelize tests

Use a matrix or built-in test parallelism to keep larger suites fast.

Self-heal transient failures

Proxy and registry timeouts flake module downloads; self-healing retries them automatically.

Lower per-minute cost

Frequent fast jobs still add up. Roughly 69% savings keeps the bill low.

Key takeaways

• Cache the module and build cache.
• Parallelize tests.
• Self-heal proxy flakes; about 69% cheaper.
