AWS API Gateway should prevent use of TLS v1

由 时间秒杀一切 提交于 2019-12-18 04:45:11

I want to understand why it is absolutely necessary to put this IP in Security Group to access the internet-facing ALB from the private

How do you create those via the aws cli? I found aws emr create-default-roles but there's no aws emr create-default-security-groups . 回答1: As of right now, it looks like you can't. See http://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-man-sec-groups.html section "To specify Amazon EMR–managed security groups
