While creating ec2 instance, we provide following inputs
- ami-id
- network settings:
- vpc-id
- subnet-id
- public ip => Enabled/Disabled
- Tags
- Security Group
- Key-Pair

Lets try to create a security group for web servers
- Allow all traffic on SSH (TCP=>22), HTTP(TCP=>80), HTTPS(TCP=>443)
- Refer Here for the documentation.
- Refer Here for the changes to be done
- After applying the changes view the security group in AWS Refer Here
-
Lets also use locals to represent the values which we are using in terraform configuration but we dont expect these values as user inputs Refer Here
-
Lets create a security group for database => Postgres (5432)
- Lets open Postgres only to ec2 instance in our vpc
- Refer Here for the changes done.
