Multi-Run Executable

Runs a RightScript or Chef Recipe on multiple active RightScale Servers.

Table of Contents


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

Basic Example


  • This is similar to Run Executable, but instead of running on a single active running server, this script updates multiple active servers, which is beneficial for running a script or recipe on server arrays.
  • When specifying RightScale input(s), you must declare both the name and value.
  • The example below runs a recipe. 
#!/bin/sh -e
curl -i -H X_API_Version:1.5 -b mycookie -X POST \
 -d recipe_name="sys_firewall::setup_rule" \
 -d inputs[][name]="sys_firewall/rule/enable" \
 -d inputs[][value]="text:enable" \
 -d inputs[][name]="sys_firewall/rule/ip_address" \
 -d inputs[][value]="text:any" \
 -d inputs[][name]="sys_firewall/rule/port" \
 -d inputs[][value]="text:22"\
 -d inputs[][name]="sys_firewall/rule" \
 -d inputs[][value]="text:tcp" \$cloud_id/instances/multi_run_executable.xml

Basic Example


  • This example runs an executable on multiple instances, even if they are outside of a Server Array
  • This is similar to Run Executable, but instead of running on a single active running server, this script updates multiple active servers.
  • By default, the executable will be run on every instance specified in the cloud unless additional filters are given.
  • When specifying RightScale input(s), you must declare both the name and value.
  • To run this script, you must know your Cloud ID as well as the Chef recipe name or Rightscript HREF, which are both obtainable from the Rightscale dashboard or using other API 1.5 calls.
  • ## Example that runs a Rightscript on all cloud instances in a single cloud with a single input
    ## Also stores the returned task object as 'task,' which in turn can be used to check summary/status
    task = @client.clouds.index(:id => 3).show.instances.multi_run_executable(:right_script_href => '/api/right_scripts/500272003', :inputs => {'INPUT1' => "text:TestValue1"})
    ## Same command, only runs a Chef recipe by name instead of a Rightscript by HREF
    task = @client.clouds.index(:id => 3).show.instances.multi_run_executable(:recipe_name => 'sys_firewall::setup_rule', :inputs => {'INPUT1' => "text:TestValue1"})

Advanced Examples

Filtering for Specific Instances

This example is similar to the above example, however many people may not wish to run the recipe or Rightscript on every instance in a single cloud. The below example allows you to run the recipe or Rightscript on specific instances defined with filters, such as:

  • In a specific cloud
  • Within a specific Deployment
  • Contains a specific string in it's Nickname
## Uses deployment_href and name filters to specify only instances within a Deployment that contain a specific string in their name

@client.clouds.index(:id => 3).show.instances.multi_run_executable(:filter => ['deployment_href==/api/deployments/434815003','name==#2'], :right_script_href => '/api/right_scripts/500272003', :inputs => {'INPUT1' => "text:TestValue1"})

Sample Output


  • Sample output below comes from interactive Ruby shell (IRB) and uses sample script and server IDs. Your script HREF and server ID would be different in your own output.
  • Sample output includes commands issued from example above.
## IRB Output from Rightscript run with one input. 

irb(main):025:0> task = @client.clouds.index(:id => 3).show.instances.multi_run_executable(:right_script_href => '/api/right_scripts/500272003', :inputs => {'INPUT1' => "text:TestValue1"})
=> #<RightApi::Resource resource_type="task">

## IRB Output from Chef recipe run

irb(main):017:0> task = @client.clouds.index(:id => 3).show.instances.multi_run_executable(:recipe_name => 'sys_firewall::setup_rule', :inputs => {'INPUT1' => "text:TestValue1"})
=> {"links"=>[], "summary"=>"0%: Multi run executable action for instances through API.", "actions"=>[]}

## Follows up on the task status

=> "completed: Multi run executable action for instances through API."


Navigating to any affected instance, then clicking on the Audit Entries tab will also give you status of the script/recipe run from the right_api_client or Curl command, as seen here:
