This repo contains a Module for deploying a custom Centos7 VMSS for a existing AKS cluster. In general there should be no need to rely on a specific OS if you use containers, however, sometimes reality requires to install some custom packages to make your software stack working.

This module provides a recipe of how to add your custom centos workers to an existing AKS.

Create an AKS instance. Since this module doe not support all versions and all features of AKS you can use the terraform module in the examples folder to get started.

Create the AKS cluster:

cd examples/aks
terraform init
terraform apply --var resource_group_name=myaks --var name=myaks --auto-approve

After we have an AKS instance we can apply the centos vmss module

cd examples/aks-centos-vmss
terraform init
terraform apply --var resource_group_name=myaks --var aks_name=myaks --var name=mycentos --auto-aprrove

when the deployment is done you should be able to see the new centos worker in the node list

kubectl get node
NAME                                 STATUS   ROLES   AGE    VERSION
aks-default-31244857-vmss000000      Ready    agent   17m    v1.20.9
aks-plain-mycentos-vmss000000        Ready    agent   5m8s   v1.20.9

Note: The VMSS is deployed into the reource group which also contains the AKS VMSS resources (MC_myaks_<aks_name>_)
