Project does not build when GOOS=darwin

[wmedlar]

/kind bug

What happened?

The project does not compile on MacOS / darwin because there is no code to implement the necessary nodeService methods like there is for Linux and Windows.

What you expected to happen?

Code compiles well enough to run e2e tests.

How to reproduce it (as minimally and precisely as possible)?

$ GOOS=darwin go build -o bin/aws-ebs-csi-driver ./cmd/
# github.com/kubernetes-sigs/aws-ebs-csi-driver/pkg/driver
pkg/driver/mount.go:63:9: cannot use &NodeMounter{…} (value of type *NodeMounter) as Mounter value in return statement: *NodeMounter does not implement Mounter (missing method GetDeviceNameFromMount)

pkg/driver/node.go:697:14: d.preparePublishTarget undefined (type *nodeService has no field or method preparePublishTarget)
pkg/driver/node.go:697:14: too many errors

Anything else we need to know?:

I don't actually want to run the driver on MacOS, but I do want to run e2e tests to validate my installation of the driver.
Currently I can work around this by running the tests in a container.

Environment

• Kubernetes version (use kubectl version): EKS 1.22
• Driver version: v1.17.0

#796 is related, but was closed without any changes being made.

Hi, building for Darwin is intentionally not supported, as the EBS CSI Driver cannot run on Darwin. Building for Darwin should not be required to run the e2e tests (you will need to build for Linux, as the e2e tests must be run on a real cluster on AWS).

[wmedlar]

The e2e tests import code from the driver, which is why building on darwin is required. The driver itself and the resources created by the tests are all run in a real cluster. Like I mentioned in the original post, I don't have any interest in running the driver on darwin. I should, however, be able to run the e2e tests from my laptop without having to jump through hoops.

A stub implementation of the nodeService would be plenty fine, as would a clean separation between the application code and the e2e tests.
