how to append new rules in aws security group using terraform

[Balaji Ramachandran]

As stated by terraform that we can modify the existing settings without destroying the running config.

I am trying to add he new security rules into the existing security group and also want to modify the existing ingress or egree rule.

How to do that? 

Best Regards

I believe it's very common to use a combination of aws_security_group and aws_security_group_rule resources:

- https://www.terraform.io/docs/providers/aws/r/security_group.html

- https://www.terraform.io/docs/providers/aws/r/security_group_rule.html

After creating the group, you can add/remove individual rules with configuration. Note that the aws_security_group_rule resource is incompatible with listing rules in-line in the configuration of aws_security_group.

Cheers,
