0001: Learning Path Foundation
Date: 2026-06-14 Status: Accepted
Context
Establishing the optimal learning sequence for a Go beginner+ aiming to contribute to cloud-native open source projects. The learner knows Go syntax basics but needs depth in idiomatic patterns. Target projects include Kubernetes, Docker, Prometheus, and similar infrastructure tools.
Insight
The learning path should follow Go's own abstraction layers: interfaces first (implicit satisfaction, io.Reader pattern), then error handling (since Go errors are just interfaces), then concurrency (goroutines + channels build on top of interface patterns). This mirrors how production Go code is structured — interfaces define contracts, concrete types implement them, and concurrency orchestrates them.
Starting with interfaces unlocks testing (mocking via interfaces), understanding the standard library, and reading real cloud-native code — all of which are prerequisites for meaningful OSS contribution.
Consequences
- Lesson 0001 will teach Go interfaces — implicit satisfaction, the
io.Reader/io.Writerpattern, interface composition, and the empty interface - Each subsequent lesson will build on interfaces as the foundational abstraction
- Reference documents should start with an interface glossary/cheat sheet
- The user should be able to read Kubernetes
client.Clientor Dockercontainer.Runtimeinterfaces after this lesson and understand the pattern
