### Running Integration Tests
```bash
./hack/prepare-for-integration-tests.sh && source /tmp/integration-test-env && go test -v -count 1 ./test/...
```
1. Install dependencies:
The `./hack/prepare-for-integration-tests.sh` script will create a local
[`kind`](https://kind.sigs.k8s.io/) cluster on which the integration tests will run.
- [`kind`](https://kind.sigs.k8s.io/docs/user/quick-start)
- [`tilt`](https://docs.tilt.dev/install.html)
- [`ytt`](https://carvel.dev/#getting-started)
- [`kubectl`](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
On macOS, these tools can be installed with [Homebrew](https://brew.sh/):
```bash
brew install kind tilt-dev/tap/tilt k14s/tap/ytt kubectl
```
1. Create a local Kubernetes cluster using `kind`:
```bash
kind create cluster --image kindest/node:v1.18.8
```
1. Install Pinniped and supporting dependencies using `tilt`:
```bash
./hack/tilt-up.sh
```
Tilt will continue running and live-updating the Pinniped deployment whenever the code changes.
1. Run the Pinniped integration tests:
```bash
source ./hack/lib/tilt/integration-test.env && go test -v -count 1 ./test/integration
```
To uninstall the test environment, run `./hack/tilt-down.sh`.
To destroy the local Kubernetes cluster, run `kind delete cluster`.

### Steps to Deploy the Latest Release on kind Using local-user-authenticator as the Identity Provider
## Example of Deploying on kind
[kind](https://kind.sigs.k8s.io) is a tool for creating and managing Kubernetes clusters on your local machine
which uses Docker containers as the cluster's "nodes". This is a convenient way to try out Pinniped on a local
non-production cluster.
The following steps will deploy the latest release of Pinniped on kind using the local-user-authenticator component
as the identity provider.

1. As the admin user, create RBAC rules for the test user to give them permissions to perform actions on the cluster.
For example, grant the test user permission to view all cluster resources.

def docker_build_sub(ref, context, extra_cmds, child_context=None, base_suffix='-tilt_docker_build_sub_base', live_update=[], **kwargs):
"""
Substitutes in a docker image with extra Dockerfile commands.
This allows you to easily customize your docker build for your dev environment without changing your prod Dockerfile.
This works by:
1. Renaming the original image to, e.g. "myimage-base"
2. Creating a new image named, e.g. "myimage" that starts with "FROM myimage-base"
3. Adding whatever extra stuff you want
Examples:
```
# load the extension
load("ext://docker_build_sub", "docker_build_sub")
# ensure you have vim installed when running in dev, so you can
# shell into the box and look at files
docker_build_sub('myimage', '.', extra_cmds=["apt-get install vim"])
# use live_update to sync files from outside your docker context
docker_build_sub('foo', 'foo', child_context='bar',
extra_cmds=['ADD . /bar'],
live_update=[
sync('foo', '/foo'),
sync('bar', '/bar'),
]
)
```
This function supports all the normal `docker_build` arguments. See [docker_build API docs](https://docs.tilt.dev/api.html#api.docker_build) for arguments not mentioned here..
Args:
context (str): The directory in which to build the parent (original) image. If child_context is not set, also the directory in which to build the new child image.
extra_cmds (List[str]): Any extra Dockerfile commands you want to run when building the image.
child_context (str): The directory in which to build the new child image. If unset (None), defaults to the parent image's context.
base_suffix (str): The suffix to append to the parent (original) image's name so that the new child image can take the original name. This is mostly ignorable, and just here in case the default generates a conflict for you.
"""

child_context = context
base_ref = '%s-base' % ref

df = '\n'.join(['FROM %s' % base_ref] + extra_cmds)
