[doc]: https://github.com/golang/go/wiki/Modules#releasing-modules-v2-or-higher Per this Go modules [doc] a repo or branch that's already tagged v2 or higher should increment the major version (e.g. go to v3) when releasing their first Go module-based packages. At the moment, the kustomize repo has these top level packages in the sigs.k8s.io/kustomize module: - `cmd` - holds main program for kustomize Conceivably someone can depend on this package for integration tests. - `internal` - intentionally unreleased subpackages - `k8sdeps` - an adapter wrapping k8s dependencies This exists only for use in pre-Go-modules kustomize-into-kubectl integration and won't live much longer (as everything involved is switching to Go modules). - `pkg` - kustomize packages for export This should shrink in later versions, since the surface area is too large, containing sub-packages that should be in 'internal'. - `plugin` - holds main programs for plugins This PR changes the top level go.mod file from ``` module sigs.k8s.io/kustomize ``` to ``` module sigs.k8s.io/kustomize/v3 ``` and adjusts all import statements to reflect the change.
