How to add condition in elbsg.config in ebextensions for elasticbeanstak

Question

Currently, we use docker-compose and .ebextensions to update elastic load balancer security group. However now I have requirement to apply different security groups for different environment. How do I add the condition to elbsg.config ? 
Below is my current elbsg.config

```
option_settings:
 aws:elb:loadbalancer:
  ManagedSecurityGroup: "sg-xxxxxx"
  SecurityGroups: "sg-xxxxx"
 aws:elbv2:loadbalancer:
  ManagedSecurityGroup: "sg-x"xxxx
  SecurityGroups: "sg-xxxxx"
```
Wondering if the normal yaml condition would works or there is a separate syntax for elbsg.config to work ?

Answer

You will likely need to have a separate bundle for the new environment which has the needed settings in it, as there is no constructs for setting up a conditional `option_settings` entry. Similarly, the YAML standard itself does not specify any such conditionals, though some tooling (such as CloudFormation) has its own special syntax for this type of need.
