Simplify SSH access to your AWS ec2 instances
We at FullStack are big on security and only allow SSH access to hosts by the IPs of our engineers. In AWS we create a single security group (SG) to allow SSH access. With the use VPNs, travel, and dynamic IPs it can some time be a pain to update a security group with your new IP. So I wrote a small python script using Boto3 that removes and updates a single ingress rule based on the description value. You just need to set the SG Id on line 5, and the value of the description on line 6 of the rule you want to update. We use a user name for the description value as it makes it easy to tell what rule belong to who.
