Requirements:
vagrant
virtualbox
This solution is contructed out of 1 master VM, n-workers VMs, and a player VM (ansible player)
You can config more or less workers than default (which is 4) if you just want to run cluster with 4 workers go to step 2
- CONFIG : you can adjust number of workers you want to have in your cluster it depends on your hardware how many it can handle
** to add workes edit Vagrantfile and change N to in 5th line to number of workers you need
** change hosts file to match number of workers you will need to add ips to them too
- BUILD VMs needed for cluster : clone this repo go inside folder and run
vagrant up
- When vagrant finished buildinmg all hosts -from within the folder ssh to player
vagrant ssh player
- go to /vagrant
cd vagrant
- Ask ansible to install k8s on VMs
ansible-playbook -i hosts 1_k8s_install.yml
- set up cluster on master VM
ansible-playbook -i hosts 2_master_cluster_setup.yml
- join your workers to cluster
ansible-playbook -i hosts 3_workers_join_cluster.yml
- check if cluster nodes are connected disconnect from player
vagrant ssh master
kubectl get nodes - you should see all workers in ready status
check deployment folder for additional deployment of an app to kubes
