Kubernetes Vagrant Setup

kubernetes-vagrant-setup

A vagrant script for setting up a Kubernetes (1.0.1) cluster on CoreOS (alpha/752.1.0). This repository was forked from Pires's github repository and changed according to Apache Stratos requirements. All the credit goes to Pires for implementing this awesome Vagrant module.

Pre-requisites

• Vagrant 1.7.2+
• Virtualbox 4.3.20+
• [Wget] (http://www.gnu.org/software/wget)

How to Run

Set-up Kubernetes Cluster

Disable DHCP server in VirtualBox:

VBoxManage dhcpserver remove --netname HostInterfaceNetworking-vboxnet0

Execute the following bash script to start a new Kubernetes cluster, this will start one master node and one minion:

run.sh

If more than one minion is needed, run the below command with the required number of instances:

run.sh NUM_INSTANCES=2

If you need to specify minion's Memory and CPU, use following command:

run.sh NUM_INSTANCES=2 NODE_MEM=4096 NODE_CPUS=2

Wait until the nodes get connected to the cluster. Once the state of the nodes are changed to Ready, the Kubernetes cluster is ready for use. Execute following Kubernetes CLI commands and verify their status:

kubectl get nodes

NAME           LABELS                                STATUS
172.17.8.102   kubernetes.io/hostname=172.17.8.102   Ready

Access the Kubernetes UI using the following URL http://172.17.8.101:8080/ui. If it complains saying that endpoints "kube-ui" not found, execute the kube-ui-pod.sh script.

Clean-up

Execute the following command to remove the virtual machines created for the Kubernetes cluster.

vagrant destroy

If you've set NUM_INSTANCES or any other variable when deploying, please make sure you set it in vagrant destroy call above, like:

NUM_INSTANCES=2 vagrant destroy
