opening up aws ec2 security groups

ec2-security-ingress.sh

    echo "Getting container/machine IP address..."
    ip_address=`curl -s icanhazip.com`
    if [ -z "$ip_address" ];then #if icanhasip failed
          ip_address=`curl -s ifconfig.me`
        if [ -z "$ip_address" ];then  #if still can't get ipaddress
        echo "Cannot get IP address, borked :-("
        exit 1 # terminate and indicate error
        fi
    else
        echo "Got IP address of $ip_address"
    fi

    echo "Opening up SSH on security group:$ec2_security_group_id for $ip_address"
    # see http://docs.aws.amazon.com/cli/latest/reference/ec2/authorize-security-group-ingress.html
    aws --region=$aws_region ec2 authorize-security-group-ingress --group-id $ec2_security_group_id --protocol tcp --port 22 --cidr $ip_address/32

    echo "Running ansible git deploy playbook"
    # my ansible/capistrano commands go here

    echo "Removing $ip_address from security group:$ec2_security_group_id"
    # see http://docs.aws.amazon.com/cli/latest/reference/ec2/revoke-security-group-ingress.html
    aws --region=$aws_region ec2 revoke-security-group-ingress --group-id $ec2_security_group_id --protocol tcp --port 22 --cidr $ip_address/32

Used in conjunction with CircleCI.com to open up our ec2 security groups to enable ansible based deploy commands.
