### Build Requirements
* A recent Go distribution (>=1.12)
* If you're not on Linux, you'll need a Docker installation
* minikube requires at least 4GB of RAM to compile, which can be problematic when using docker-machine

#### Prerequisites for different GNU/Linux distributions

##### Fedora
On Fedora you need to install _glibc-static_

```shell
$ sudo dnf install -y glibc-static
```

### Building from Source
Clone minikube into your go path under `$GOPATH/src/k8s.io`

```shell
$ git clone https://github.com/kubernetes/minikube.git $GOPATH/src/k8s.io/minikube
$ cd $GOPATH/src/k8s.io/minikube
$ make
```

Note: Make sure that you uninstall any previous versions of minikube before building
from the source.

### Building from Source in Docker (using Debian stretch image with golang)
Clone minikube:
```shell
$ git clone https://github.com/kubernetes/minikube.git
```
Build (cross compile for linux / OS X and Windows) using make:
```shell
$ cd minikube
$ docker run --rm -v "$PWD":/go/src/k8s.io/minikube -w /go/src/k8s.io/minikube golang:stretch make cross
```
Check "out" directory:
```shell
$ ls out/
docker-machine-driver-hyperkit.d	minikube				minikube.d				test.d
docker-machine-driver-kvm2.d		minikube-linux-amd64			storage-provisioner.d
```

### Run Instructions

Start the cluster using your built minikube with:

```shell
$ ./out/minikube start
```

### Running Tests

#### Unit Tests

Unit tests are run on Travis before code is merged. To run as part of a development cycle:

```shell
make test
```

#### Integration Tests

Integration tests are currently run manually.
To run them, build the binary and run the tests:

```shell
make integration
```

#### Conformance Tests

These are Kubernetes tests that run against an arbitrary cluster and exercise a wide range of Kubernetes features.
You can run these against minikube by following these steps:

* Clone the Kubernetes repo somewhere on your system.
* Run `make quick-release` in the k8s repo.
* Start up a minikube cluster with: `minikube start`.
* Set following two environment variables:
```shell
export KUBECONFIG=$HOME/.kube/config
export KUBERNETES_CONFORMANCE_TEST=y
```
* Run the tests (from the k8s repo):
```shell
go run hack/e2e.go -v --test --test_args="--ginkgo.focus=\[Conformance\]" --check-version-skew=false
```

To run a specific conformance test, you can use the `ginkgo.focus` flag to filter the set using a regular expression.
The `hack/e2e.go` wrapper and the `e2e.sh` wrappers have a little trouble with quoting spaces though, so use the `\s` regular expression character instead.
For example, to run the test `should update annotations on modification [Conformance]`, use following command:

```shell
go run hack/e2e.go -v --test --test_args="--ginkgo.focus=should\supdate\sannotations\son\smodification" --check-version-skew=false
```
