| // IMPORTANT: THIS IS NOT COMPLETE CODE. THIS IS JUST A SAMPLE TO HELP YOU WRITE YOUR OWN UPGRADE AUTOMATION | |
| /* | |
| What should you include in your code: | |
| 1. create an AWS session and k8s kubeconfig context. These variables can be taken as user input | |
| 2. disable cluster autoscaler by setting the replica count to 0 | |
| 3. create AWS autoscaling object. This will be required to query the existing ASG and perform | |
| required modifications for the upgrade process | |
| 4. create a main upgrade job which will trigger the upgrade by performing following actions: | |
| - get a list of all ASG in your cluster |

| Description: >- | |
| This template deploys a new VPC and creates a new subnet and custom route table. | |
| It uses a cloudformation custom resource which invokes a lambda function to | |
| set the custom route table as the defaul MAIN route table. | |
| Lambda function is using boto3(python sdk) function 'replace_route_table_association(**kwargs)' to replace the main routetable. | |
| replace_route_table_association(**kwargs) function itself needs two parameters to make this change. | |
| parameter1 # routetableassociationId of the existing main routetable. This is identified by iterating each route table in VPC | |
| parameter2 # routetableId of the custom routetable. This is a reference to the new route table resource created in this template. | |
