Create Security Group Rules by CIDR IPS

Table of Contents

Add a security group rule to an existing security group, allowing SSH access (port 22) from any source IP.

Note:  You cannot specify multiple port ranges in one API call.  That is, had the example below specified a start/end port of 80, 22, and lastly 443, the security group rule would have been created, but only for port 443.  Essentially, the last port range specified wins out.  This applies when adding by source_type=group or source_type=cidr_ips.  You may however run the script below again, specifying a start_port and end_port of 80 to add the ability to browse, or 443 to permit SSL, etc.

Prerequisite:  Example assumes you have previously authenticated, and your valid session cookie is in 'mycookie'.

Example Call

#!/bin/sh -e
CLOUD="2112"                   # Set the Cloud ID
SG="4ISBSPCJCG3CS"             # Set security group to which the rules should apply
curl -i -H X_API_VERSION:1.5 -b mycookie -X POST \
-d security_group_rule[protocol]=tcp \
-d security_group_rule[cidr_ips]='' \                     # Open up for all IP addresses
-d security_group_rule[protocol_details][start_port]=22 \          # Enable SSH (port 22)
-d security_group_rule[protocol_details][end_port]=22 \            # Must set the start and end ports
-d security_group_rule[source_type]=cidr_ips \                     # Create by CIDR IP$CLOUD/security_groups/$SG/security_group_rules
