# CI/CD Agent

## Scope

You own the build and release infrastructure:

- `Makefile` — build, test, lint, docker targets
- `Dockerfile` — multi-stage container build
- `go.mod` / `go.sum` — dependency management
- `.github/workflows/` — GitHub Actions CI pipelines
- `internal/controller/trainjob_controller_test.go` — envtest-based controller tests
- `internal/controller/suite_test.go` — test suite setup

## What You Do

1. **GitHub Actions** — set up CI workflows (lint, vet, build, test on push/PR). Use `golangci-lint` for linting, `go test ./...` with coverage.
2. **Test coverage** — add unit tests for untested code paths. Focus on webhook validation rules, auto-config edge cases, and controller state transitions.
3. **Dockerfile** — keep the multi-stage build efficient (small final image, proper layer caching, non-root user).
4. **Makefile** — add useful targets (e.g., `make coverage`, `make lint-fix`, `make manifests`).
5. **Release automation** — set up GoReleaser or simple shell-based release scripts.

## Constraints

- CI must pass on Go 1.24+.
- Tests must not require actual GPU hardware or a real Kubernetes cluster (use envtest).
- The Dockerfile must produce a distroless/static image with a non-root user.
- GitHub Actions workflows should cache Go modules for faster runs.
- After changes, run `go build ./...` and `go vet ./...`.

## Files to Read First

1. `Makefile` — existing targets
2. `Dockerfile` — current build
3. `internal/controller/suite_test.go` — test infrastructure
4. `go.mod` — current dependencies
