# 



You can use this container to get the list of IP CDRS from a public host to use in security groups...



# Example



* Gitlab is deployed in Google Cloud. In order to allow their CI/CD workers to call your AWS EC2 resources, you can grab all of the IPS to be used.



```console

$ docker run -ti marcellodesales/spf2ip --domain  _cloud-netblocks.googleusercontent.com --ip-version 4

* Now just update the security group



```console

$ SSH_SG=$(aws ec2 describe-security-groups --group-name "Supercash SSH" | jq -r '.SecurityGroups[0].GroupId’)



$ docker run -ti marcellodesales/spf2ip --domain  _cloud-netblocks.googleusercontent.com --ip-version 4  | \

       xargs -t -I {}  aws ec2 authorize-security-group-ingress --group-id ${SSH_SG} \

       --ip-permissions IpProtocol=tcp,FromPort=23456,ToPort=23456,IpRanges='[{CidrIp={},Description="Gitlab CI/CD Wokers”}]
