# How to move a utility pkg from other kubernetes repos
It has 2 steps to move a pkg from other Kubernetes repos to `k8s.io/utils` repo:
- copy the pkg to `k8s.io/utils` repo
- update the import paths and `vendor/` in the repos that refer this pkg
## Copy the pkg to `k8s.io/utils` repo
Copying should preserve all the git history associated with it.
[Here](http://gbayer.com/development/moving-files-from-one-git-repository-to-another-preserving-history/) is a working approach.
Note: You may need to use `--allow-unrelated-histories` if you get error when running `git pull` following the post above.
Then, you may need to restructure the package to make sure it has the following structure.
.
├── doc.go # Description for this package
├── <utilname1>.go # utility go file
├── <utilname>_test.go # go unit tests
└── testing # All the testing framework
└── fake_<utilname>.go # Testing framework go file
[#5](https://github.com/kubernetes/utils/pull/5) is an example for this step.
## Update the repos that refer the pkg
You should update the import paths.
Then follow [this doc](https://github.com/kubernetes/community/blob/master/contributors/devel/godep.md) to update `vendor/` and `Godeps/`.
You may want to run `make bazel-test` to make sure all new references work.
[kubernetes/kubernetes#49234](https://github.com/kubernetes/kubernetes/pull/49234) is an example for this step.

# Utils
[![Build Status]](https://travis-ci.org/kubernetes/utils) [![GoDoc](https://godoc.org/k8s.io/utils?status.svg)](https://godoc.org/k8s.io/utils)
A set of Go libraries that provide low-level,
kubernetes-independent packages supplementing the [Go
standard libs].
## Purpose
As Kubernetes grows and spins functionality out of its
[core] and into cooperating repositories like
[apiserver], [kubectl], [kubeadm], etc., the need
arises for leaf repositories to house shared code and
avoid cycles in repository relationships.
This repository is intended to hold shared utilities
with no Kubernetes dependence that may be of interest
to any Go project. See these [instructions for moving]
an existing package to this repository.
## Criteria for adding code here
- Used by multiple Kubernetes repositories.
- Full unit test coverage.
- Go tools compliant (`go get`, `go test`, etc.).
- Complex enough to be worth vendoring, rather than copying.
- Stable, or backward compatible, API.
- _No dependence on any Kubernetes repository_.
## Libraries
- [Exec](/exec) provides an interface for `os/exec`. It makes it easier
to mock and replace in tests, especially with
the [FakeExec](exec/testing/fake_exec.go) struct.
- [Temp](/temp) provides an interface to create temporary directories. It also
provides a [FakeDir](temp/temptest) implementation to replace in tests.
- [Clock](/clock) provides an interface for time-based operations. It allows
mocking time for testing.
- [Pointers](/pointers) provides some functions for pointer-based operations.
[Build Status]: https://travis-ci.org/kubernetes/utils.svg?branch=master
[Go standard libs]: https://golang.org/pkg/#stdlib
[api]: https://github.com/kubernetes/api
