AWS CLI Get Security Group ID with Name.[ wild card support] Bash Script

 Hi guys,

If you are wondering How can I get the ID of an AWS security group if I know the name?

Here is the solution.

Get the Security ID with the wild card Name.

#!/bin/bash
#Author Praveen
SearchString=<*YourSearchString*> # Note : wild cards supported 
  
 for VPCS in `aws ec2 --output text --query 'Vpcs[*].{VpcId:VpcId}' describe-vpcs` ; do
  aws ec2 describe-security-groups --filter Name=vpc-id,Values=$VPCS Name=group-name,Values=$searchstring --query 'SecurityGroups[*].[GroupId]' --output text 
 done


2. With the above solution we can automate the other tasks. eg:  add tags to security groups.

     for VPCS in `aws ec2 --output text --query 'Vpcs[*].{VpcId:VpcId}' describe-vpcs` ; do
      echo "  Tagging Search String Created Security Groups" 

	 	    aws ec2 describe-security-groups --filter Name=vpc-id,Values=$VPCS 	  Name=group- name,Values=$searchstring --query 'SecurityGroups[*].[GroupId]' --output text | xargs - I {} aws ec2 create-tags --resources {} --tags --tags '[{"Key":"tag1","Value":"tag1"}, 
  {"Key":"tag2", "Value":"tag2"},{"Key":"tag3", "Value":"tag3"},{"Key":"tag4", 
   "Value":"tag4"},{"Key":"tag5", "Value":"tag5"}]'
 echo "Successfully Tagged "
 done
