vagrant-rancher2.0

This example shows a rancher2.0 server and kubernetes worker servers based on a docker environment on top of a VM-based vagrant local(OSX/Windows) environment.. Rancher[1] is an well known attractive tool for orchestrating containers in a docker environment. Rancher ver1.6 uses swarm-based cattle engine, kubernetes, mesos, etc., while ver2.0 supports only kubernetes engine and is under full reorganization. There is a way to develop a docker application locally by configuring a container environment pool based on the vagrant VM.[2]

if use OSX and use rb, this is better example.[3].

Design

Prerequisites Install

Install Vagrant and Virtual Box in your local(OSX/Windows) environment.

1. Vagrant

Vagrant is required as this is used to provision the machine based on the Vagrantfile.

• https://www.vagrantup.com/downloads.html

2. Virtual Box

The virtual machines that Vagrant provisions need to be provisioned to VirtualBox.

• https://www.virtualbox.org/wiki/Downloads

3. Docker

• windows: https://docs.docker.com/toolbox/toolbox_install_windows/
• osx : https://docs.docker.com/docker-for-mac/
• linux : https://docs.docker.com/install/linux/docker-ce/ubuntu/

4.Source Pull

git clone  https://github.com/hyeonsangjeon/vagrant-rancher2.0.git

5. Deploying vagrant VM rancher server

cd vagrant-rancher2.0
vagrant up rancher 

6. Deploying vagrant VM kubernetes worker node server

cd vagrant-rancher2.0
vagrant up vmhost01
vagrant up vmhost01 && vmhost02  

vm server information are as follows,

info	Description	ssh
Rancher server	https://192.200.10.100	22
K8S Worker servers	192.200.10.1x	22

vagrant command,

info	Description
vagrant up	This command creates and configures guest machines according to your Vagrantfile.[4]
vagrant destroy	This command stops the running machine Vagrant is managing and destroys all resources that were created during the machine creation process.
vagrant ssh	This will SSH into a running Vagrant machine and give you access to a shell.

If want into vagrant server terminal,

cd vagrant-rancher2.0
vagrant ssh rancher
vagrant ssh vmhost01
vagrant ssh vmhost0x
