TODO: This document was manually maintained so might be incomplete. The
automation effort is tracked in
https://github.com/kubernetes/test-infra/issues/5843.
Changes in `k8s.io/api` and `k8s.io/apimachinery` are mentioned here
because `k8s.io/client-go` depends on them.
# v10.0.0
**Breaking Changes:**
* Action required: client-go will no longer have bootstrap
(`k8s.io/client-go/tools/bootstrap`) related code. Any reference to it will
break. Please redirect all references to `k8s.io/bootstrap` instead.
([#67356](https://github.com/kubernetes/kubernetes/pull/67356))
* The methods `NewSelfSignedCACert` and `NewSignedCert` now use `crypto.Signer`
interface instead of `rsa.PrivateKey` for certificate creation. This is done
to allow different kind of private keys (for example: ecdsa).
([#69329](https://github.com/kubernetes/kubernetes/pull/69329))
* `GetScale` and `UpdateScale` methods have been added for `apps/v1` clients
and with this, no-verb scale clients have been removed.
([#70437](https://github.com/kubernetes/kubernetes/pull/70437))
* `k8s.io/client-go/util/cert/triple` package has been removed.
([#70966](https://github.com/kubernetes/kubernetes/pull/70966))
**New Features:**
* `unfinished_work_microseconds` is added to the workqueue metrics.
It can be used to detect stuck worker threads (kube-controller-manager runs many workqueues.).
([#70884](https://github.com/kubernetes/kubernetes/pull/70884))
* A method `GetPorts` is added to expose the ports that were forwarded.
This can be used to retrieve the locally-bound port in cases where the input was port 0.
([#67513](https://github.com/kubernetes/kubernetes/pull/67513))
* Dynamic listers and informers, that work with `runtime.Unstructured` objects,
are added. These are useful for writing generic, non-generated controllers.
([68748](https://github.com/kubernetes/kubernetes/pull/68748))
* The dynamic fake client now supports JSONPatch.
([#69330](https://github.com/kubernetes/kubernetes/pull/69330))
* The `GetBinding` method is added for pods in the fake client.
([#69412](https://github.com/kubernetes/kubernetes/pull/69412))
**Bug fixes and Improvements:**
* The `apiVersion` and action name values for fake evictions are now set.
([#69035](https://github.com/kubernetes/kubernetes/pull/69035))
* PEM files containing both TLS certificate and key can now be parsed in
arbitrary order. Previously key was always required to be first.
([#69536](https://github.com/kubernetes/kubernetes/pull/69536))
* Go clients created from a kubeconfig that specifies a `TokenFile` now
periodically reload the token from the specified file.
([#70606](https://github.com/kubernetes/kubernetes/pull/70606))
* It is now ensured that oversized data frames are not written to
spdystreams in `remotecommand.NewSPDYExecutor`.
([#70999](https://github.com/kubernetes/kubernetes/pull/70999))
* A panic occuring on calling `scheme.Convert` is fixed by populating the fake
dynamic client scheme. ([#69125](https://github.com/kubernetes/kubernetes/pull/69125))
* Add step to correctly setup permissions for the in-cluster-client-configuration example.
([#69232](https://github.com/kubernetes/kubernetes/pull/69232))
* The function `Parallelize` is deprecated. Use `ParallelizeUntil` instead.
([#68403](https://github.com/kubernetes/kubernetes/pull/68403))
* [k8s.io/apimachinery] Restrict redirect following from the apiserver to
same-host redirects, and ignore redirects in some cases.
([#66516](https://github.com/kubernetes/kubernetes/pull/66516))
## API changes
**New Features:**
* GlusterFS PersistentVolumes sources can now reference endpoints in any
namespace using the `spec.glusterfs.endpointsNamespace` field.
Ensure all kubelets are upgraded to 1.13+ before using this capability.
([#60195](https://github.com/kubernetes/kubernetes/pull/60195))
* The [dynamic audit configuration](https://github.com/kubernetes/community/blob/master/keps/sig-auth/0014-dynamic-audit-configuration.md)
API is added. ([#67547](https://github.com/kubernetes/kubernetes/pull/67547))
* A new field `EnableServiceLinks` is added to the `PodSpec` to indicate whether
information about services should be injected into pod's environment variables.
([#68754](https://github.com/kubernetes/kubernetes/pull/68754))
* `CSIPersistentVolume` feature, i.e. `PersistentVolumes` with
`CSIPersistentVolumeSource`, is GA. `CSIPersistentVolume` feature gate is now
deprecated and will be removed according to deprecation policy.
([#69929](https://github.com/kubernetes/kubernetes/pull/69929))
* Raw block volume support is promoted to beta, and enabled by default.
This is accessible via the `volumeDevices` container field in pod specs,
and the `volumeMode` field in persistent volume and persistent volume claims definitions.
([#71167](https://github.com/kubernetes/kubernetes/pull/71167))
**Bug fixes and Improvements:**

is set to `MaxInt32`. ([#66605](https://github.com/kubernetes/kubernetes/pull/66605))
* `procMount` field is no longer incorrectly marked as required in openapi schema.
([#69694](https://github.com/kubernetes/kubernetes/pull/69694))
* The caBundle and service fields in admission webhook API objects now correctly
indicate they are optional. ([#70138](https://github.com/kubernetes/kubernetes/pull/70138))
# v9.0.0
**Breaking Changes:**
* client-go now supports additional non-alpha-numeric characters in UserInfo
"extra" data keys. It should be updated in order to properly support extra
data containing "/" characters or other characters disallowed in HTTP headers.
Old clients sending keys which were `%`-escaped by the user will have their
values unescaped by new API servers.
([#65799](https://github.com/kubernetes/kubernetes/pull/65799))
* `apimachinery/pkg/watch.Until` has been moved to
`client-go/tools/watch.UntilWithoutRetry`. While switching please consider
using the new `client-go/tools/watch.UntilWithSync` or `client-go/tools/watch.Until`.
([#66906](https://github.com/kubernetes/kubernetes/pull/66906))
* [k8s.io/apimachinery] `Unstructured` metadata accessors now respect omitempty semantics
i.e. a field having zero value will now be removed from the unstructured metadata map.
([#67635](https://github.com/kubernetes/kubernetes/pull/67635))
* [k8s.io/apimachinery] The `ObjectConvertor` interface is now changed such that
`ConvertFieldLabel` func takes GroupVersionKind as an argument instead of just
version and kind. ([#65780](https://github.com/kubernetes/kubernetes/pull/65780))
* [k8s.io/apimachinery] componentconfig `ClientConnectionConfiguration` is
moved to `k8s.io/apimachinery/pkg/apis/config`.
([#66058](https://github.com/kubernetes/kubernetes/pull/66058))
* [k8s.io/apimachinery] Renamed ` KubeConfigFile` to `Kubeconfig` in
`ClientConnectionConfiguration`.
([#67149](https://github.com/kubernetes/kubernetes/pull/67149))
* [k8s.io/apimachinery] JSON patch no longer supports `int`.
([#63522](https://github.com/kubernetes/kubernetes/pull/63522))
**New Features:**
* Add ability to cancel leader election.
This also proves useful in integration tests where the whole app is started and
stopped in each test. ([#57932](https://github.com/kubernetes/kubernetes/pull/57932))
* An example showing how to use fake clients in tests is added.
([#65291](https://github.com/kubernetes/kubernetes/pull/65291))

([#66249](https://github.com/kubernetes/kubernetes/pull/66249))
* Fix kubelet startup failure when using `ExecPlugin` in kubeconfig.
([#66395](https://github.com/kubernetes/kubernetes/pull/66395))
* Fix panic in the fake `SubjectAccessReview` client when object is nil.
([#66837](https://github.com/kubernetes/kubernetes/pull/66837))
* Periodically reload `InClusterConfig` token.
([#67359](https://github.com/kubernetes/kubernetes/pull/67359))
* [k8s.io/apimachinery] Report parsing error in json serializer.
([#63668](https://github.com/kubernetes/kubernetes/pull/63668))
* [k8s.io/apimachinery] The `metav1.ObjectMeta` accessor does not deepcopy
owner references anymore. In general, the accessor interface does not enforce
deepcopy nor does it forbid it (e.g. for `unstructured.Unstructured`).
([#64915](https://github.com/kubernetes/kubernetes/pull/64915))
* [k8s.io/apimachinery] Utility functions `SetTransportDefaults` and `DialerFor`
once again respect custom Dial functions set on transports.
([#65547](https://github.com/kubernetes/kubernetes/pull/65547))
* [k8s.io/apimachinery] Speed-up conversion function invocation by avoiding
`reflect.Call`. Action required: regenerated conversion with conversion-gen.
([#65771](https://github.com/kubernetes/kubernetes/pull/65771))

unmarshable protobuf serialization error.
([#67041](https://github.com/kubernetes/kubernetes/pull/67041))
* [k8s.io/apimachinery] Immediately close the other side of the connection by
exiting once one side closes when proxying.
([#67288](https://github.com/kubernetes/kubernetes/pull/67288))
## API changes
**Breaking Changes:**
* Volume dynamic provisioning scheduling has been promoted to beta.
ACTION REQUIRED: The DynamicProvisioningScheduling alpha feature gate has been removed.
The VolumeScheduling beta feature gate is still required for this feature.
([#67432](https://github.com/kubernetes/kubernetes/pull/67432))
* The CSI file system type is no longer defaulted to ext4.
All the production drivers listed under https://kubernetes-csi.github.io/docs/Drivers.html
were inspected and should not be impacted after this change.
If you are using a driver not in that list,
please test the drivers on an updated test cluster first.
([#65499](https://github.com/kubernetes/kubernetes/pull/65499))

which implement metric selectors for Object and Pods metrics,
as well as allowing AverageValue targets on Objects, similar to External metrics.
([#64097](https://github.com/kubernetes/kubernetes/pull/64097))
* Add `Lease` API in the `coordination.k8s.io` API group.
([#64246](https://github.com/kubernetes/kubernetes/pull/64246))

to allow paths in the container's `/proc` to not be masked.
([#64283](https://github.com/kubernetes/kubernetes/pull/64283))
* Add the `AuditAnnotations` field to `ImageReviewStatus` to allow the
`ImageReview` backend to return annotations to be added to the created pod.
([#64597](https://github.com/kubernetes/kubernetes/pull/64597))
* SCTP is now supported as additional protocol (alpha) alongside TCP and UDP in
Pod, Service, Endpoint, and NetworkPolicy.
([#64973](https://github.com/kubernetes/kubernetes/pull/64973))

restoring a volume from a volume snapshot data source.
([#67087](https://github.com/kubernetes/kubernetes/pull/67087))
* `RuntimeClass` is a new API resource for defining different classes of runtimes
that may be used to run containers in the cluster.
Pods can select a `RunitmeClass` to use via the `RuntimeClassName` field.
This feature is in alpha, and the `RuntimeClass` feature gate must be enabled
in order to use it. ([#67737](https://github.com/kubernetes/kubernetes/pull/67737))
* To address the possibility dry-run requests overwhelming admission webhooks
that rely on side effects and a reconciliation mechanism, a new field is being
added to `admissionregistration.k8s.io/v1beta1.ValidatingWebhookConfiguration`
and `admissionregistration.k8s.io/v1beta1.MutatingWebhookConfiguration` so that
webhooks can explicitly register as having dry-run support.
If a dry-run request is made on a resource that triggers a non dry-run supporting
webhook, the request will be completely rejected, with "400: Bad Request".
Additionally, a new field is being added to the
`admission.k8s.io/v1beta1.AdmissionReview` API object, exposing to webhooks
whether or not the request being reviewed is a dry-run.
([#66936](https://github.com/kubernetes/kubernetes/pull/66936))
**Bug fixes and Improvements:**
* The `DisruptedPods` field in `PodDisruptionBudgetStatus` is now optional.
([#63757](https://github.com/kubernetes/kubernetes/pull/63757))
* `extensions/v1beta1` Deployment's `ProgressDeadlineSeconds` now defaults to `MaxInt32`.
([#66581](https://github.com/kubernetes/kubernetes/pull/66581))

# v7.0.0
**Breaking Changes:**
* Google Cloud Service Account email addresses can now be used in RBAC Role bindings since the default scopes now include the `userinfo.email` scope.

Clients may request alternate representations of normal Kubernetes objects by passing an `Accept` header like `application/json;as=Table;g=meta.k8s.io;v=v1beta1` or `application/json;as=PartialObjectMetadata;g=meta.k8s.io;v1=v1beta1`. Older servers will ignore this representation or return an error if it is not available. Clients may request fallback to the normal object by adding a non-qualified mime-type to their `Accept` header like `application/json` - the server will then respond with either the alternate representation if it is supported or the fallback mime-type which is the normal object response.

# v3.0.0
Bug fixes:
* Use OS-specific libs when computing client User-Agent in kubectl, etc. (https://github.com/kubernetes/kubernetes/pull/44423)
* kubectl commands run inside a pod using a kubeconfig file now use the namespace specified in the kubeconfig file, instead of using the pod namespace.

# Installing client-go
## For the casual user
If you want to write a simple script, don't care about a reproducible client
library install, don't mind getting head (which may be less stable than a
particular release), then simply:
```sh
$ go get k8s.io/client-go/...
```
This will install `k8s.io/client-go` in your `$GOPATH`. `k8s.io/client-go`
includes most of its own dependencies in its `k8s.io/client-go/vendor` path,
except for `k8s.io/apimachinery` and `glog`. `go get` will recursively download
these excluded repos to your `$GOPATH`, if they don't already exist. If
`k8s.io/apimachinery` preexisted in `$GOPATH`, you also need to:
```sh
$ go get -u k8s.io/apimachinery/...
```
because the head of client-go is only guaranteed to work with the head of
apimachinery.
We excluded `k8s.io/apimachinery` and `glog` from `k8s.io/client-go/vendor` to
prevent `go get` users from hitting issues like
[#19](https://github.com/kubernetes/client-go/issues/19) and
[#83](https://github.com/kubernetes/client-go/issues/83). If your project share
other dependencies with client-go, and you hit issues similar to #19 or #83,
then you'll need to look down at the next section.
Note: the official go policy is that libraries should not vendor their
dependencies. This is unworkable for us, since our dependencies change and HEAD
on every dependency has not necessarily been tested with client-go. In fact,
HEAD from all dependencies may not even compile with client-go!
## Dependency management for the serious (or reluctant) user
Reasons why you might need to use a dependency management system:
* You use a dependency that client-go also uses, and don't want two copies of
the dependency compiled into your application. For some dependencies with
singletons or global inits (e.g. `glog`) this wouldn't even compile...
* You want to lock in a particular version (so you don't have to change your
code every time we change a public interface).
* You want your install to be reproducible. For example, for your CI system or
for new team members.
There are three tools you could in theory use for this. Instructions
for each follows.
### Godep
[godep](https://github.com/tools/godep) is an older dependency management tool, which is
used by the main Kubernetes repo and `client-go` to manage dependencies.
Before proceeding with the below instructions, you should ensure that your
$GOPATH is empty except for containing your own package and its dependencies,
and you have a copy of godep somewhere in your $PATH.
To install `client-go` and place its dependencies in your `$GOPATH`:
```sh
go get k8s.io/client-go/...
cd $GOPATH/src/k8s.io/client-go
git checkout v9.0.0 # replace v9.0.0 with the required version
# cd 1.5 # only necessary with 1.5 and 1.4 clients.
godep restore ./...
```
At this point, `client-go`'s dependencies have been placed in your $GOPATH, but
if you were to build, `client-go` would still see its own copy of its
dependencies in its `vendor` directory. You have two options at this point.
If you would like to keep dependencies in your own project's vendor directory,
then you can continue like this:
```sh
cd $GOPATH/src/<my-pkg>
godep save ./...
```
Alternatively, if you want to build using the dependencies in your `$GOPATH`,
then `rm -rf vendor/` to remove `client-go`'s copy of its dependencies.
### Glide
[Glide](https://github.com/Masterminds/glide) is another popular dependency
management tool for Go. Glide will manage your /vendor directory, but unlike
godep, will not use or modify your $GOPATH (there's no equivalent of
`godep restore` or `godep save`).
Generally, it's best to avoid Glide's many subcommands, favoring modifying
Glide's manifest file (`glide.yaml`) directly, then running
`glide update --strip-vendor`. First create a `glide.yaml` file at the root of
your project:
```yaml
package: ( your project's import path ) # e.g. github.com/foo/bar
import:
- package: k8s.io/client-go
version: v9.0.0 # replace v9.0.0 with the required version
```
Second, add a Go file that imports `client-go` somewhere in your project,
otherwise `client-go`'s dependencies will not be added to your project's
vendor/. Then run the following command in the same directory as `glide.yaml`:
```sh
glide update --strip-vendor
```
This can also be abbreviated as:
```sh
glide up -v
```
At this point, `k8s.io/client-go` should be added to your project's vendor/.
`client-go`'s dependencies should be flattened and be added to your project's
vendor/ as well.
Glide will detect the versions of dependencies `client-go` specified in
`client-go`'s Godep.json file, and automatically set the versions of these
imports in your /vendor directory. It will also record the detected version of
all dependencies in the `glide.lock` file.
Projects that require a different version of a dependency than `client-go`
requests can override the version manually in `glide.yaml`. For example:
```yaml
package: ( your project's import path ) # e.g. github.com/foo/bar
import:
- package: k8s.io/client-go
version: v9.0.0 # replace v9.0.0 with the required version
# Use a newer version of go-spew even though client-go wants an old one.
- package: github.com/davecgh/go-spew
version: v1.1.0
```
After modifying, run `glide up -v` again to re-populate your /vendor directory.
Optionally, Glide users can also use [`glide-vc`](https://github.com/sgotti/glide-vc)
after running `glide up -v` to remove unused files from /vendor.
### Dep (Not supported yet!)
[dep](https://github.com/golang/dep) is an up-and-coming dependency management
tool, which has the goal of being accepted as part of the standard go toolchain.
However, client-go does **NOT** work well with `dep` yet. To support `dep`, we
need to fix at least two issues:
1. publish native `Gopkg.toml` in client-go and other k8s.io repos, like `k8s.io/apimachinery`;
2. find a way to express transitive constraints (see https://github.com/golang/dep/issues/1124).
As a workaround, which may or may not be worthwhile, you can specify all
client-go dependencies manually as
[override](https://github.com/golang/dep/blob/master/docs/Gopkg.toml.md#override)
in Gopkg.toml with the versions listed in [Godeps.json](./Godeps/Godeps.json),
and manually update them when you upgrade client-go version.
We are actively working on the two issues blocking using `dep`. For the
meantime, we recommend using `glide` or `godeps`.

# client-go
Go clients for talking to a [kubernetes](http://kubernetes.io/) cluster.
We currently recommend using the v10.0.0 tag. See [INSTALL.md](/INSTALL.md) for
detailed installation instructions. `go get k8s.io/client-go/...` works, but
will build `master`, which doesn't handle the dependencies well.

### What's included
* The `kubernetes` package contains the clientset to access Kubernetes API.
* The `discovery` package is used to discover APIs supported by a Kubernetes API server.
* The `dynamic` package contains a dynamic client that can perform generic operations on arbitrary Kubernetes API objects.
* The `plugin/pkg/client/auth` packages contain optional authentication plugins for obtaining credentials from external sources.
* The `transport` package is used to set up auth and start a connection.
* The `tools/cache` package is useful for writing controllers.
### Versioning
`client-go` follows [semver](http://semver.org/). We will not make
backwards-incompatible changes without incrementing the major version number. A
change is backwards-incompatible either if it *i)* changes the public interfaces
of `client-go`, or *ii)* makes `client-go` incompatible with otherwise supported
versions of Kubernetes clusters.
Changes that add features in a backwards-compatible way will result in bumping
the minor version (second digit) number.
Bugfixes will result in the patch version (third digit) changing. PRs that are
cherry-picked into an older Kubernetes release branch will result in an update
to the corresponding branch in `client-go`, with a corresponding new tag
changing the patch version.
A consequence of this is that `client-go` version numbers will be unrelated to
Kubernetes version numbers.
#### Branches and tags.
We will create a new branch and tag for each increment in the major version number or
minor version number. We will create only a new tag for each increment in the patch
version number. See [semver](http://semver.org/) for definitions of major,
minor, and patch.
The master branch will track HEAD in the main Kubernetes repo and
accumulate changes. Consider HEAD to have the version `x.(y+1).0-alpha` or
`(x+1).0.0-alpha` (depending on whether it has accumulated a breaking change or
not), where `x` and `y` are the current major and minor versions.
#### Compatibility: your code <-> client-go
`client-go` follows [semver](http://semver.org/), so until the major version of
client-go gets increased, your code will compile and will continue to work with
explicitly supported versions of Kubernetes clusters. You must use a dependency
management system and pin a specific major version of `client-go` to get this
benefit, as HEAD follows the upstream Kubernetes repo.
#### Compatibility: client-go <-> Kubernetes clusters
Since Kubernetes is backwards compatible with clients, older `client-go`
versions will work with many different Kubernetes cluster versions.
We will backport bugfixes--but not new features--into older versions of
`client-go`.
#### Compatibility matrix
| | Kubernetes 1.7 | Kubernetes 1.8 | Kubernetes 1.9 | Kubernetes 1.10 | Kubernetes 1.11 | Kubernetes 1.12 | Kubernetes 1.13 |
|---------------------|----------------|----------------|----------------|-----------------|-----------------|-----------------|-----------------|
| client-go 4.0 | ✓ | +- | +- | +- | +- | +- | +- |
| client-go 5.0 | +- | ✓ | +- | +- | +- | +- | +- |
| client-go 6.0 | +- | +- | ✓ | +- | +- | +- | +- |
| client-go 7.0 | +- | +- | +- | ✓ | +- | +- | +- |
| client-go 8.0 | +- | +- | +- | +- | ✓ | +- | +- |
| client-go 9.0 | +- | +- | +- | +- | +- | ✓ | +- |
| client-go 10.0 | +- | +- | +- | +- | +- | +- | ✓ |
| client-go HEAD | +- | +- | +- | +- | +- | +- | +- |
Key:
* `✓` Exactly the same features / API objects in both client-go and the Kubernetes
version.
* `+` client-go has features or API objects that may not be present in the
Kubernetes cluster, either due to that client-go has additional new API, or
that the server has removed old API. However, everything they have in
common (i.e., most APIs) will work. Please note that alpha APIs may vanish or
change significantly in a single release.
* `-` The Kubernetes cluster has features the client-go library can't use,
either due to the server has additional new API, or that client-go has
removed old API. However, everything they share in common (i.e., most APIs)
will work.
See the [CHANGELOG](./CHANGELOG.md) for a detailed description of changes
between client-go versions.
| Branch | Canonical source code location | Maintenance status |
|----------------|--------------------------------------|-------------------------------|
| client-go 1.4 | Kubernetes main repo, 1.4 branch | = - |
| client-go 1.5 | Kubernetes main repo, 1.5 branch | = - |
| client-go 2.0 | Kubernetes main repo, 1.5 branch | = - |
| client-go 3.0 | Kubernetes main repo, 1.6 branch | = - |
| client-go 4.0 | Kubernetes main repo, 1.7 branch | = - |
| client-go 5.0 | Kubernetes main repo, 1.8 branch | = - |
| client-go 6.0 | Kubernetes main repo, 1.9 branch | = - |
| client-go 7.0 | Kubernetes main repo, 1.10 branch | = - |
| client-go 8.0 | Kubernetes main repo, 1.11 branch | ✓ |
| client-go 9.0 | Kubernetes main repo, 1.12 branch | ✓ |
| client-go 10.0 | Kubernetes main repo, 1.13 branch | ✓ |
| client-go HEAD | Kubernetes main repo, master branch | ✓ |
Key:
* `✓` Changes in main Kubernetes repo are actively published to client-go by a bot
* `=` Maintenance is manual, only severe security bugs will be patched.
* `-` Deprecated; please upgrade.
#### Deprecation policy
We will maintain branches for at least six months after their first stable tag
is cut. (E.g., the clock for the release-2.0 branch started ticking when we
tagged v2.0.0, not when we made the first alpha.) This policy applies to
every version greater than or equal to 2.0.
#### Why do the 1.4 and 1.5 branch contain top-level folder named after the version?
For the initial release of client-go, we thought it would be easiest to keep
separate directories for each minor version. That soon proved to be a mistake.
We are keeping the top-level folders in the 1.4 and 1.5 branches so that
existing users won't be broken.
### Kubernetes tags
This repository is still a mirror of
[k8s.io/kubernetes/staging/src/client-go](https://github.com/kubernetes/kubernetes/tree/master/staging/src/k8s.io/client-go),
the code development is still done in the staging area. Since Kubernetes 1.8
release, when syncing the code from the staging area, we also sync the Kubernetes
version tags to client-go, prefixed with "kubernetes-". For example, if you check
out the `kubernetes-v1.8.0` tag in client-go, the code you get is exactly the
same as if you check out the `v1.8.0` tag in kubernetes, and change directory to
`staging/src/k8s.io/client-go`. The purpose is to let users quickly find matching
commits among published repos, like
[sample-apiserver](https://github.com/kubernetes/sample-apiserver),
[apiextension-apiserver](https://github.com/kubernetes/apiextensions-apiserver),
etc. The Kubernetes version tag does NOT claim any backwards compatibility
guarantees for client-go. Please check the [semantic versions](#versioning) if
you care about backwards compatibility.
### How to get it
You can use `go get k8s.io/client-go/...` to get client-go, but **you will get
the unstable master branch** and `client-go`'s vendored dependencies will not be
added to your `$GOPATH`. So we think most users will want to use a dependency
management system. See [INSTALL.md](/INSTALL.md) for detailed instructions.
### How to use it
If your application runs in a Pod in the cluster, please refer to the
in-cluster [example](examples/in-cluster-client-configuration), otherwise please
refer to the out-of-cluster [example](examples/out-of-cluster-client-configuration).
### Dependency management
If your application depends on a package that client-go depends on, and you let the Go compiler find the dependency in `GOPATH`, you will end up with duplicated dependencies: one copy from the `GOPATH`, and one from the vendor folder of client-go. This will cause unexpected runtime error like flag redefinition, since the go compiler ends up importing both packages separately, even if they are exactly the same thing. If this happens, you can either
* run `godep restore` ([godep](https://github.com/tools/godep)) in the client-go/ folder, then remove the vendor folder of client-go. Then the packages in your GOPATH will be the only copy
* or run `godep save` in your application folder to flatten all dependencies.
### Contributing code
Please send pull requests against the client packages in the Kubernetes main [repository](https://github.com/kubernetes/kubernetes). Changes in the staging area will be published to this repository every day.
