Getting started with vSphere
|
|
-------------------------------
|
|
|
|
The example below creates a Kubernetes cluster with 4 worker node Virtual
|
|
Machines and a master Virtual Machine (i.e. 5 VMs in your cluster). This
|
|
cluster is set up and controlled from your workstation (or wherever you find
|
|
convenient).

|
|
|
|
### 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. Get or build a [binary release](binary_release.md)
|
|
|
|
### Setup
|
|
|
|
Download a prebuilt Debian 7.7 VMDK that we'll use as a base image:
|
|
|
|
```sh
|
|
curl --remote-name-all https://storage.googleapis.com/govmomi/vmdk/2014-11-11/kube.vmdk.gz{,.md5}
|
|
md5sum -c kube.vmdk.gz.md5
|
|
gzip -d kube.vmdk.gz
|
|
```
|
|
|
|
Import this VMDK into your vSphere datastore:
|
|
|
|
```sh
|
|
export GOVC_URL='user:pass@hostname'
|
|
export GOVC_INSECURE=1 # If the host above uses a self-signed cert
|
|
export GOVC_DATASTORE='target datastore'
|
|
export GOVC_RESOURCE_POOL='resource pool or cluster with access to datastore'
|
|
|
|
govc import.vmdk kube.vmdk ./kube/
|
|
```
|
|
|
|
Verify that the VMDK was correctly uploaded and expanded to ~3GiB:
|
|
|
|
```sh
|
|
govc datastore.ls ./kube/
|
|
```
|
|
|
|
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`.
|
|
|
|
### Starting a cluster
|
|
|
|
Now, let's continue with deploying Kubernetes.
|
|
This process takes about ~10 minutes.
|
|
|
|
```sh
|
|
cd kubernetes # Extracted binary release OR repository root
|
|
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!**
|
|
|
|
### Extra: debugging deployment failure
|
|
|
|
The output of `kube-up.sh` displays the IP addresses of the VMs it deploys. You
|
|
can log into any VM as the `kube` user to poke around and figure out what is
|
|
going on (find yourself authorized with your SSH key, or use the password
|
|
`kube` otherwise).
