Shell script to get the IP address of running instance

[Amit Saini]

Hi,

Is there any shell script to get the IP address of running instance from scalr database...??

Regards

Would the query be originating from the local instance, the Scalr servers, or some other location?

Hi Amit,

As Jeff noted, we need to get a bit of additional context about your use case so that we may provide the best recommendation.  Are you attempting to query this from the Scalr server and retrieve results from the Scalr database, or are you looking to obtain this information on your running instances as part of an Orchestration script?  Otherwise, are you looking to gather this information from your local workstation? What do you plan to do with these IPs once you have your query results?  This information will help to clarify your needs and isolate the best method to achieve your desired results.

Many thanks,
Wm. Marc O'Brien

Hi Amit,

Depending on the scope of the IPs you are interested in, you should be able to achieve this by using szradm queryenv within your orchestration script.  Let us know if you have any questions or troubles with implementation.

Many thanks,

Amit, this is already available to your scripts in the built-in Global Variables. Just make a simple script like:

#!/bin/bash

env

Then put it on the BeforeHostUp event on one of your Farm Roles and launch an instance. If you then look in the Orchestration Log, you will be able to see the complete list of built-in Global Variables that are available to your script.

In your specific case, as you need the instance IP address, the name of the Global Variables are:

SCALR_INTERNAL_IP

SCALR_EXTERNAL_UP

Access them in your script as normal Environment Variables, such as:

echo $SCALR_INTERNAL_IP

echo $SCALR_EXTERNAL_IP
