## Getting started with vSphere

### Prerequisites

1. You need administrator credentials to an ESXi machine or vCenter instance.
2. You must have Go (version 1.2 or later) installed: [www.golang.org](http://www.golang.org).
3. You must have your `GOPATH` set up and include `$GOPATH/bin` in your `PATH`.

   ```sh
   export GOPATH=$HOME/src/go
   mkdir -p $GOPATH
   export PATH=$PATH:$GOPATH/bin
   ```

4. Install the govc tool to interact with ESXi/vCenter:

   ```sh
   go get github.com/vmware/govmomi/govc
   ```

5. Install godep (optional, only required when modifying package dependencies). [Instructions here](https://github.com/GoogleCloudPlatform/kubernetes#installing-godep)

6. Get the Kubernetes source:

   ```sh
   go get github.com/GoogleCloudPlatform/kubernetes
   cd $GOPATH/src/github.com/GoogleCloudPlatform/kubernetes
   ```

### Setup

Download a prebuilt Debian VMDK to be used as base image:

```sh
wget https://storage.googleapis.com/govmomi/vmdk/kube.vmdk.gz{,.md5}
md5sum -c kube.vmdk.gz.md5
gzip -d kube.vmdk.gz
```

Upload this VMDK to your vSphere instance:

```sh
export GOVC_URL='https://user:pass@hostname/sdk'
export GOVC_DATASTORE='target datastore'
export GOVC_RESOURCE_POOL='resource pool with access to datastore'

govc datastore.import kube.vmdk
```

Verify that the VMDK was correctly uploaded and expanded to 10GiB:

```sh
govc datastore.ls
```

Take a look at the file `cluster/vsphere/config-common.sh` fill in the required
parameters. The guest login for the image that you imported is `kube:kube`.

Now, let's continue with deploying Kubernetes:

```sh
cd kubernetes

# Build source
hack/build-go.sh

# Build a release (argument is the instance prefix)
release/build-release.sh kubernetes

# Deploy Kubernetes (takes ~5 minutes, provided everything works out)
export KUBERNETES_PROVIDER=vsphere
cluster/kube-up.sh
```

Refer to the top level README and the getting started guide for Google Compute
Engine. Once you have successfully reached this point, your vSphere Kubernetes
deployment works just as any other one!

**Enjoy!**
