Vagrant Install
|
|
=================
|
|
|
|
Assuming you have Vagrant (1.8+) installed with virtualbox (it may work
|
|
with vmware, but is untested) you should be able to launch a 3 node
|
|
Kubernetes cluster by simply running `$ vagrant up`.<br />
|
|
|
|
This will spin up 3 VMs and install kubernetes on them. Once they are
|
|
completed you can connect to any of them by running <br />
|
|
`$ vagrant ssh k8s-0[1..3]`.
|
|
|
|
```
|
|
$ vagrant up
|
|

Customize Vagrant
|
|
=================
|
|
|
|
You can override the default settings in the `Vagrantfile` either by directly modifying the `Vagrantfile`
|
|
or through an override file.
|
|
|
|
In the same directory as the `Vagrantfile`, create a folder called `vagrant` and create `config.rb` file in it.
|
|
|
|
You're able to override the variables defined in `Vagrantfile` by providing the value in the `vagrant/config.rb` file,
|
|
e.g.:
|
|
|
|
echo '$forwarded_ports = {8001 => 8001}' >> vagrant/config.rb
|
|
|
|
and after `vagrant up` or `vagrant reload`, your host will have port forwarding setup with the guest on port 8001.
|
|
|
|
Use alternative OS for Vagrant
|
|
==============================
|
|
|
|
By default, Vagrant uses Ubuntu 16.04 box to provision a local cluster. You may use an alternative supported
|
|
operating system for your local cluster.
|
|
|
|
Customize `$os` variable in `Vagrantfile` or as override, e.g.,:
|
|
|
|
echo '$os = "coreos-stable"' >> vagrant/config.rb
|
|
|
|
|
|
The supported operating systems for vagrant are defined in the `SUPPORTED_OS` constant in the `Vagrantfile`.
