[SOLVED] Modifying rules for a given EC2 security group with Boto3

Issue

I have recently been working on programatically adding and removing ingress rules to security groups on my EC2 server. However, I now seem to have hit a bit of a wall.

I would like to be able to modify existing rules through a python script, but I haven't been able to find any guidance on the Boto3 docs.

Is there any way in which this can be done?

Thanks

Solution

See Boto3:SecurityGroup

There is no API to modify a rule in SG. You have to revoke the rule first and then add the rule with the modified parameters using authorize. The link also has code snippets.

• authorize_egress()
• authorize_ingress()
• revoke_egress()
• revoke_ingress()
