How it works...
For this module, we need to specify the name of the security group. The rule that we are creating will be associated with this group. We have to supply the protocol and the port range information. If we just want to whitelist only one port, then that would be the upper and lower bound of the range. Lastly, we have to specify the allowed addresses in the form of CIDR. The address 0.0.0.0/0 signifies that port 80 is open for everyone. This task will add an ingress type rule and allow traffic on port 80 to reach the instance. Similarly, we have to add a rule to allow traffic on port 22 as well.
