OCPBUGS-92032: Dockerfile: Copy only build-required files in builder stage

[Miciah]

Replace the broad "COPY . ." instruction in the builder stage with targeted COPY instructions for only the files and directories that "make build" requires. This excludes documentation, CI configuration, and other files that are not needed for the build, reducing the amount of data copied into the builder image.

Summary by CodeRabbit

• Chores
  • Streamlined the container build process to include only the files needed for compilation.
  • Kept the final runtime image and delivered application binary unchanged.

Walkthrough

The Dockerfile’s builder stage now copies selected build inputs explicitly instead of the full build context. The build command and final runtime stage remain unchanged.

Changes

Dockerfile builder stage update

Layer / File(s)	Summary
Explicit builder COPY Dockerfile	The builder stage replaces COPY . . with explicit copies of Makefile, go.mod, go.sum, .git, cmd/, pkg/, and vendor/.

✅ Passed checks (15 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title check	✅ Passed	The title accurately and concisely describes the main Dockerfile builder-stage copy change.
Docstring Coverage	✅ Passed	No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check.
Linked Issues check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Out of Scope Changes check	✅ Passed	Check skipped because no linked issues were found for this pull request.
Stable And Deterministic Test Names	✅ Passed	No Ginkgo specs use dynamic titles; the only subtests use static string-literal names like tc.name/tt.name tables.
Test Structure And Quality	✅ Passed	No Ginkgo test code was changed; the PR only updates Dockerfile copy instructions, so the test-quality check is not applicable.
Microshift Test Compatibility	✅ Passed	Only Dockerfile changed in this commit; no Ginkgo/e2e test files or test code were added or modified, so MicroShift compatibility is not implicated.
Single Node Openshift (Sno) Test Compatibility	✅ Passed	The PR only changes Dockerfile COPY instructions; no Go/Ginkgo test files were added or modified, so SNO compatibility is not applicable.
Topology-Aware Scheduling Compatibility	✅ Passed	The PR only narrows Dockerfile COPY inputs; no deployment manifests, controllers, replicas, affinity, selectors, or topology-aware scheduling code were modified.
Ote Binary Stdout Contract	✅ Passed	PASS — the PR only changes Dockerfile COPY instructions; no process-level Go code was modified, and main/suite setup shows no stdout writes.
Ipv6 And Disconnected Network Test Compatibility	✅ Passed	PR only changes Dockerfile, .ci-operator.yaml, and go.mod; no Ginkgo e2e tests or IPv4/external-connectivity logic were added.
No-Weak-Crypto	✅ Passed	Dockerfile-only change; it just narrows COPY inputs for the builder stage and adds no weak-crypto, custom-crypto, or token-compare code.
Container-Privileges	✅ Passed	Only the Dockerfile changed; no non-vendor manifests contain privileged, hostPID/Network/IPC, allowPrivilegeEscalation, or SYS_ADMIN settings.
No-Sensitive-Data-In-Logs	✅ Passed	Only Dockerfile COPY instructions changed; no logging code or sensitive data exposure was added.
