This repository is here to set up a sandbox to train kubernetes students. Couple of
scripts create the environment in Lunanode, a cloud service provider in Toronto, they have the lowest price.
for KVM virtual machines. Their service is awesome.
see their website here.
Get an API credentials from the lunanode website, see here
Save your API credentials in a file under your $HOME directory, change the line 7 in the file
create_vm_cluster.py accordingly to your environment.
This script is a quick and dirty experimental solution for
setting up a cluster of 1 master and 2 nodes. It's linear so read it as it's be done and make some tests beforehand
So I use to change it by naming each VM using a color reference, line 15 and test it in line 35
(Note: I set a timer -line 25- for letting lunanode enough time for provisioning all public IP addresses for each VMs)
The create_vm_cluster script save all cluster ip addresse, password and user name in a file so you should change it accordingly to the following structure for your inventory file.
[node]
ip_address ansible_ssh_user=ubuntu ansible_ssh_pass=password ansible_ssh_extra_args='-o StrictHostKeyChecking=no'
ip_address ansible_ssh_user=ubuntu ansible_ssh_pass=password ansible_ssh_extra_args='-o StrictHostKeyChecking=no'
[master]
ip_address ansible_ssh_user=ubuntu ansible_ssh_pass=password ansible_ssh_extra_args='-o StrictHostKeyChecking=no'
Example:
ansible-playboox -i /home/hme/iventory playbook
##Note: If you are outside the lunanode network you should change the following code suitable to your network topology.
- name: get primary ip address
shell: ip route get 1 | awk '{print $NF;exit}'
