ec2\_group (as of Ansible 2.4) doesn’t support usage of pl-xxxxx (prefix lists) typically employed by VPC endpoints.

So I went down the rabbit hole of doing this via a command module. The command works on the prompt. How do I get this to work?

`  
ERROR! Syntax Error while loading YAML.

The error appears to have been in ‘/Users/dgirard/Documents/kraken/git/Ansible-aws-security/EC2-Security-Groups/SG-uat.yml’: line 2384, column 150, but may  
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:

# aws ec2 authorize-security-group-egress --group-id “{{ sg\_id }}” --region “{{ region }}” --profile “{{ profile }}” --ip-permissions ‘[{“IpProtocol”: “tcp”, “FromPort”: 443, “ToPort”: 443, “PrefixListIds”: [{“PrefixListId”: “pl-63a5400a”}]}]’

command: aws ec2 authorize-security-group-egress --group-id “{{ sg\_id }}” --region us-east-1 --profile utility --ip-permissions ‘[{“IpProtocol”: “tcp”, “FromPort”: 443, “ToPort”: 443, “PrefixListIds”: [{“PrefixListId”: “pl-63a5400a”}]}]’  
^ here  
We could be wrong, but this one looks like it might be an issue with  
missing quotes. Always quote template expression brackets when they  
start a value. For instance:

with\_items:

- {{ foo }}

Should be written as:

with\_items:

- “{{ foo }}”

exception type: \<class ‘yaml.scanner.ScannerError’\>  
exception: mapping values are not allowed in this context  
in “”, line 2384, column 150

My workaround that works: (not “dry” yet) but you get the idea.
