Development

Tooling: Go (version per go.mod), Docker + Buildx, Helm v3, kind, golangci-lint. Codegen tools are installed by make -C deployments/devel install-tools.

Make targets

make build         # go build ./...
make cmds          # build the five binaries in cmd/
make test          # race-enabled unit tests
make generate      # CRDs, deepcopy, clientset, listers, informers
make check         # golangci-lint + check-generate  (the CI gate)
make helm-lint     # lint the Helm chart
make bats          # BATS integration tests  (needs a live cluster)

Prefix any target with docker- to run it in the devel container (requires BUILD_DEVEL_IMAGE=yes).

Local cluster

export KIND_CLUSTER_NAME=kind-dra-1
./demo/clusters/kind/build-dra-driver-gpu.sh     # build & load driver image
./demo/clusters/kind/create-cluster.sh           # create the cluster
./demo/clusters/kind/install-dra-driver-gpu.sh   # helm install

Iterate: edit → rerun the build script → rerun the install script.

GPU-aware variant: demo/clusters/nvkind/. GKE recipes: demo/clusters/gke/.

Tests

• Unit: make test.
• BATS: tests/bats/ — invasive, runs against a real cluster. Read tests/bats/README.md first.

CI

GitHub Actions in .github/workflows/ run lint, codegen check, unit tests, build, chart lint, and CodeQL. End-to-end GPU tests run on Prow / Lambda Cloud — see hack/ci/lambda/e2e-test.sh.
