change TRUNCATED to DATA+OMITTED in kubectl config view

**What this PR does / why we need it**:
Based on the discussion in #61573, this PR switches the replacement text for CA certificate data and client certificates and secrets printed using `kubectl config view`. Currently, `REDACTED` is used, which might give a false impression that the data is a secret (which is not true for the public certificates).

This PR changes `REDACTED` to `DATA+OMITTED`. The printed string is the base64 encoded string on the byte stream. Some trickery is involved to print a readable string (refer to [this comment](https://github.com/kubernetes/kubernetes/pull/66023/files#diff-aec000ca3f293c94dcd99b4a9d1c5c3cL86) for more info).

**Which issue(s) this PR fixes**:
Fixes #61573

**Special notes for your reviewer**:

**Release note**:
```release-note
Switched certificate data replacement from "REDACTED" to "DATA+OMITTED"
```

update github.com/imdario/mergo to v0.3.5

**What this PR does / why we need it**:
Updates github.com/imdario/mergo library to v0.3.5. We were pinned because of a functionality change in the dependency, however, a new function was introduced with similar functionality to the old.

There is apparently some Debian packaging issues (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=878254) because of this. I'm still not clear what those are, unless they are forcing the library to update, as opposed to using our `vendor/`.

That said, this will allow for some of those vendor conflicts to resolve for anyone else who is using client-go, so that's at least worthwhile.

**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
fixes #27543, fixes https://github.com/kubernetes/client-go/issues/431

cfba9881e4 gcp client auth plugin: persist default cache on unauthorized
The default cache for a cachedTokenSource is not always empty. In the
case of commandTokenSource, it contains calling details for the
external command that is used to generate refresh tokens. Persisting
a completely empty cache will thus break ability for the plugin to
obtain refresh tokens. This changes the roundtripper to persist
the default cache instead of assuming an empty map.

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:**

"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))
* [k8s.io/apimachinery] Create and Update now support `CreateOptions` and `UpdateOptions`.
([#65105](https://github.com/kubernetes/kubernetes/pull/65105))
**Bug fixes and Improvements:**
* Decrease the amount of time it takes to modify kubeconfig
files with large amounts of contexts.
([#67093](https://github.com/kubernetes/kubernetes/pull/67093))
* The leader election client now renews timeout.
([#65094](https://github.com/kubernetes/kubernetes/pull/65094))
* Switched certificate data replacement from `REDACTED` to `DATA+OMITTED`.
([#66023](https://github.com/kubernetes/kubernetes/pull/66023))
* Fix listing in the fake dynamic client.
([#66078](https://github.com/kubernetes/kubernetes/pull/66078))
* Fix discovery so that plural names are no longer ignored if a singular name is not specified.
([#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))
* [k8s.io/apimachinery] Establish "406 Not Acceptable" response for
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))
**New Features:**
* Support annotations for remote admission webhooks.
([#58679](https://github.com/kubernetes/kubernetes/pull/58679))
* Support both directory and block device for local volume
plugin `FileSystem` `VolumeMode`.
([#63011](https://github.com/kubernetes/kubernetes/pull/63011))
* Introduce `autoscaling/v2beta2` and `custom_metrics/v1beta2`,
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))
* `ProcMount` added to `SecurityContext` and `AllowedProcMounts` added to `PodSecurityPolicy`
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))
* The `PodShareProcessNamespace` feature to configure PID namespace sharing
within a pod has been promoted to beta.
([#66507](https://github.com/kubernetes/kubernetes/pull/66507))
* Add `TTLSecondsAfterFinished` to `JobSpec` for cleaning up Jobs after they finish.
([#66840](https://github.com/kubernetes/kubernetes/pull/66840))
* Add `DataSource` and `TypedLocalObjectReference` fields to support
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`.

## 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
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@master
$ go get k8s.io/client-go/...
```
This will record a dependency on `k8s.io/client-go` in your go module.
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).
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:
This assumes you are using go modules with go 1.11+.
If you get a message like `cannot use path@version syntax in GOPATH mode`,
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 +46,117 @@ 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 v6.0.0
# 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: v6.0.0
```
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: v6.0.0
# 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 (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`.

### Versioning
- For each `v1.x.y` Kubernetes release, the major version (first digit)
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.

Changes that add features in a backwards-compatible way will result in bumping

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
version number. See [semver](http://semver.org/) for definitions of major,
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
`(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
The `v0.x.y` tags indicate that go APIs may change in incompatible ways in
different versions.
See [INSTALL.md](INSTALL.md) for guidelines on requiring a specific
version of 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.

* 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.

# 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

## 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.
