-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.
+TODO: This document was neglected and is currently not complete. Working on

-# v10.0.0
-
-**Breaking Changes:**
-
-* Action required: client-go will no longer have bootstrap

-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).

-**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. This is a breaking change if the numeric uniqueIDs of the Google service accounts were being used in RBAC role bindings.

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.

+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

-see the instructions for [enabling go modules](#enabling-go-modules).
+```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
 
@@ -32,50 +46,135 @@ Reasons why you might need to use a dependency management system:
 * You want your install to be reproducible. For example, for your CI system or
   for new team members.
 
-### Enabling go modules
+There are three tools you could in theory use for this. Instructions
+for each follows.
 
-Dependency management tools are built into go 1.11+ in the form of [go modules](https://github.com/golang/go/wiki/Modules).
-These are used by the main Kubernetes repo (>= `v1.15.0`) and `client-go` (>= `kubernetes-1.15.0`) to manage dependencies.
-If you are using go 1.11 or 1.12 and are working with a project located within `$GOPATH`,
-you must opt into using go modules:
+### Godep
+
+[godep](https://github.com/tools/godep) is an older dependency management tool, which is
+used by the main Kubernetes repo and `client-go` to manage dependencies.
+
+Before proceeding with the below instructions, you should ensure that your
+$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
-export GO111MODULE=on
+go get k8s.io/client-go/...
+cd $GOPATH/src/k8s.io/client-go
+git checkout v2.0.0
+# cd 1.5 # only necessary with 1.5 and 1.4 clients.
+godep restore ./...
 ```
 
-Ensure your project has a `go.mod` file defined at the root of your project.
-If you do not already have one, `go mod init` will create one for you:
+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
-go mod init
+cd $GOPATH/src/<my-pkg>
+godep save ./...
 ```
 
-### Add client-go as a dependency
+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.
 
-Indicate which version of `client-go` your project requires:
+### Glide
 
-- If you are using Kubernetes versions >= `v1.17.0`, use a corresponding
-`v0.x.y` tag. For example, `k8s.io/client-go@v0.17.0` corresponds to Kubernetes `v1.17.0`:
+[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: v2.0.0
+```
+
+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
-go get k8s.io/client-go@v0.17.0
+glide update --strip-vendor
 ```
 
-You can also use a non-semver `kubernetes-1.x.y` tag to refer to a version
-of `client-go` corresponding to a given Kubernetes release. Prior to Kubernetes
-`v1.17.0` these were the only tags available for use with go modules.
-For example, `kubernetes-1.16.3` corresponds to Kubernetes `v1.16.3`.
-However, it is recommended to use semver-like `v0.x.y` tags over non-semver
-`kubernetes-1.x.y` tags to have a seamless experience with go modules.
-
-- If you are using Kubernetes versions < `v1.17.0` (replace `kubernetes-1.16.3` with the desired version):
+This can also be abbreviated as:
 
 ```sh
-go get k8s.io/client-go@kubernetes-1.16.3
+glide up -v
 ```
 
-You can now import and use the `k8s.io/client-go` APIs in your project.
-The next time you `go build`, `go test`, or `go run` your project,
-`k8s.io/client-go` and its dependencies will be downloaded (if needed),
-and detailed dependency version info will be added to your `go.mod` file
-(or you can also run `go mod tidy` to do this directly).
+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: v2.0.0
+# 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
+
+[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. Its
+status is currently alpha. However, it comes the closest to working easily out
+of the box.
+
+```sh
+$ go get github.com/golang/dep
+$ go install github.com/golang/dep/cmd/dep
+
+# Make sure you have a go file in your directory which imports a package of
+# k8s.io/client-go first--I suggest copying one of the examples.
+$ dep init
+$ dep ensure k8s.io/client-go@^2.0.0
+```
+
+Then you can try one of the
+[examples](https://github.com/kubernetes/client-go/tree/v2.0.0/examples/) from
+the 2.0.0 release.
+
+This will set up a `vendor` directory in your current directory, add `k8s.io/client-go`
+to it, and flatten all of `k8s.io/client-go`'s dependencies into that vendor directory,
+so that your code and `client-go` will both get the same copy of each
+dependency.
+
+After installing like this, you could either use dep for your other
+dependencies, or copy everything in the `vendor` directory into your
+`$GOPATH/src` directory and proceed as if you had done a fancy `go get` that
+flattened dependencies sanely.
+
+One thing to note about dep is that it will omit dependencies that aren't
+actually used, and some dependencies of `client-go` are used only if you import
+one of the plugins (for example, the auth plugins). So you may need to run `dep
+ensure` again if you start importing a plugin that you weren't using before.

 ### Versioning

-would remain `0`.
+`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.

+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 minor version
-number. We will create only a new tag for each increment in the patch
+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

 minor, and patch.
 
-The HEAD of the master branch in client-go will track the HEAD of the master
-branch in the main Kubernetes repo.
+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

-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
 
-Use go1.11+ and fetch the desired version using the `go get` command. For example:
-
-```
-go get k8s.io/client-go@v0.20.0
-```
-
-See [INSTALL.md](/INSTALL.md) for detailed instructions.
+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).
+If your application runs in a Pod in the cluster, please refer to the in-cluster [example](examples/in-cluster/main.go), otherwise please refer to the out-of-cluster [example](examples/out-of-cluster/main.go).
 
 ### Dependency management
 
-For details on how to correctly use a dependency management for installing client-go, please see [INSTALL.md](INSTALL.md).
+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.
+Please send pull requests against the client packages in the Kubernetes main [repository](https://github.com/kubernetes/kubernetes), and run the `/staging/copy.sh` script to update the staging area in the main repository. Changes in the staging area will be published to this repository every day.

-Several plugins for obtaining credentials from external sources are available, but are not loaded by default.
-To enable these plugins in your program, import them in your main package.

-# Create, Update & Delete Deployment with the Dynamic Package
-
-This example program demonstrates the fundamental operations for managing on
-[Deployment][1] resources, such as `Create`, `List`, `Update` and `Delete` using client-go's `dynamic` package.
-
-## Typed Vs. Dynamic
-The code in this directory is based on a similar [example that uses Kubernetes typed client sets][2]. The typed client sets make it simple to communicate with the API server using pre-generated local API objects to achieve an RPC-like programming experience.  Typed clients uses program compilations to enforce data safety and some validation.  However, when using typed clients, programs are forced to be tightly coupled with the version and the types used.
-
-
-The `dynamic` package on the other hand, uses a simple type, `unstructured.Unstructured`, to represent all object values from the API server. Type `Unstructured` uses a collection of nested `map[string]interface{}` values to create an internal structure that closely resemble the REST payload from the server.  
-
-The dynamic package defers all data bindings until runtime.  This means programs that use the dynamic client will not get any of the benefits of type validation until the program is running.  This may be a problem for certain types of applications that require strong data type check and validation.
-
-Being loosely coupled, however, means that programs that uses the `dynamic` package do not require recompilation when the client API changes.  The client program has more flexibility in handling updates to the API surface without knowing ahead of time what those changes are. 
-
-
-## Running this example
-
-Make sure you have a Kubernetes cluster and `kubectl` is configured:
-```
-kubectl get nodes
-```
-
-Compile this example on your workstation:
-
-```
-cd dynamic-create-update-delete-deployment
-go build -o ./app
-```
-
-Now, run this application on your workstation with your local kubeconfig file:
-
-```
-./app
-# or specify a kubeconfig file with flag
-./app -kubeconfig=$HOME/.kube/config
-```
-
-Running this command will execute the following operations on your cluster:
-
-1. **Create Deployment:** This will create a 2 replica Deployment. Verify with
-   `kubectl get pods`.
-2. **Update Deployment:** This will update the Deployment resource created in
-   previous step by setting the replica count to 1 and changing the container
-   image to `nginx:1.13`. You are encouraged to inspect the retry loop that
-   handles conflicts. Verify the new replica count and container image with
-   `kubectl describe deployment demo`.
-3. **List Deployments:** This will retrieve Deployments in the `default`
-   namespace and print their names and replica counts.
-4. **Delete Deployment:** This will delete the Deployment object and its
-   dependent ReplicaSet resource. Verify with `kubectl get deployments`.
-
-Each step is separated by an interactive prompt. You must hit the
-<kbd>Return</kbd> key to proceed to the next step. You can use these prompts as
-a break to take time to run `kubectl` and inspect the result of the operations
-executed.
-
-You should see an output like the following:
-
-```
-Creating deployment...
-Created deployment "demo-deployment".
--> Press Return key to continue.
-
-Updating deployment...
-Updated deployment...
--> Press Return key to continue.
-
-Listing deployments in namespace "default":
- * demo-deployment (1 replicas)
--> Press Return key to continue.
-
-Deleting deployment...
-Deleted deployment.
-```
-
-## Cleanup
-
-Successfully running this program will clean the created artifacts. If you
-terminate the program without completing, you can clean up the created
-deployment with:
-
-    kubectl delete deploy demo-deployment
-
-## Troubleshooting
-
-If you are getting the following error, make sure Kubernetes version of your
-cluster is v1.13 or higher in `kubectl version`:
-
-    panic: the server could not find the requested resource

-# Leader Election Example
-
-This example demonstrates how to use the leader election package.
-
-## Running
-
-Run the following three commands in separate terminals. Each terminal needs a unique `id`.
-
-```bash
-# first terminal
-go run main.go -kubeconfig=/path/to/kubeconfig -logtostderr=true -lease-lock-name=example -lease-lock-namespace=default -id=1
-
-# second terminal
-go run main.go -kubeconfig=/path/to/kubeconfig -logtostderr=true -lease-lock-name=example -lease-lock-namespace=default -id=2
-
-# third terminal
-go run main.go -kubeconfig=/path/to/kubeconfig -logtostderr=true -lease-lock-name=example -lease-lock-namespace=default -id=3
-```
-
-> You can ignore the `-kubeconfig` flag if you are running these commands in the Kubernetes cluster.
-
-Now kill the existing leader. You will see from the terminal outputs that one of the remaining two processes will be elected as the new leader.

+# Third Party Resources Example – Deprecated
+
+**Note:** ThirdPartyResources are deprecated since 1.7. The successor is CustomResourceDefinition in the apiextensions.k8s.io API group.
+
+This particular example demonstrates how to perform basic operations such as:
+
+* How to register a new ThirdPartyResource (custom Resource type)
+* How to create/get/list instances of your new Resource type (update/delete/etc work as well but are not demonstrated) 
+* How to setup a controller on Resource handling create/update/delete events
+
+## Running
+
+```
+# assumes you have a working kubeconfig, not required if operating in-cluster
+go run *.go -kubeconfig=$HOME/.kube/config
+```
+
+## Use Cases
+
+ThirdPartyResources can be used to implement custom Resource types for your Kubernetes cluster.
+These act like most other Resources in Kubernetes, and may be `kubectl apply`'d, etc.
+
+Some example use cases:
+
+* Provisioning/Management of external datastores/databases (eg. CloudSQL/RDS instances)
+* Higher level abstractions around Kubernetes primitives (eg. a single Resource to define an etcd cluster, backed by a Service and a ReplicationController) 
+
+## Defining types
+
+Each instance of your ThirdPartyResource has an attached Spec, which should be defined via a `struct{}` to provide data format validation.
+In practice, this Spec is arbitrary key-value data that specifies the configuration/behavior of your Resource.
+
+For example, if you were implementing a ThirdPartyResource for a Database, you might provide a DatabaseSpec like the following:
+
+``` go
+type DatabaseSpec struct {
+	Databases []string `json:"databases"`
+	Users     []User   `json:"users"`
+	Version   string   `json:"version"`
+}
+
+type User struct {
+	Name     string `json:"name"`
+	Password string `json:"password"`
+}
+```
