设置 AWS 安全组入站规则让 Gilabci 管道在 RDS 中进行更改

Question

I am able to access AWS RDS from gitlabci pipeline using 0.0.0.0/0 CidrIp but it is widely opened.

This is my SecurityGroupIngress definition in cloudformation file:

SecurityGroupIngress:
                -   CidrIp: 0.0.0.0/0
                    FromPort: 5432
                    ToPort: 5432
                    IpProtocol: TCP
                    Description: Allows traffic from gitlb ci

It works fine.

I have no idea how to set gitlabci's ip address range to make AWS RDS more secure.

I found this docs: gitlab ip range

There is link to all possible ip addresses on google cloud cloude.josn

Here is similar topic on stackoverflow

I need ip and mask.

For outgoing connections from CI/CD runners, we are not providing static IP addresses. All GitLab.com shared runners are deployed into Google Cloud Platform (GCP) in us-east1

Here is a list of all GCP CIDR blocks in us-east1 , assuming you are using Gitlab runners.

"34.23.0.0/16"
"34.24.0.0/15"
"34.26.0.0/16"
"34.73.0.0/16"
"34.74.0.0/15"
"34.98.128.0/21"
"34.118.250.0/23"
"34.138.0.0/15"
"34.148.0.0/16"
