# 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/temptesting) implementation to replace in tests.
|
||
|
|
||
|
- [Clock](/clock) provides an interface for time-based operations. It allows
|
||
|
mocking time for testing.
