tCloudStop Properties

Component family

Cloud

 

Function

This component accesses the cloud provider to be used (Amazon EC2) and suspends, resumes or terminates given instance(s).

Purpose

This component allows you to change the status of a launched instance on Amazon EC2 (Amazon Elastic Compute Cloud).

Basic settings

Access key and Secret key

Enter or paste the access key and the secret key required by Amazon to authenticate your requests to its web services. These access credentials are generated from the Security Credential view of your Amazon account page.

To enter the secret key, click the [...] button next to the secret key field, and then in the pop-up dialog box enter the password between double quotes and click OK to save the settings.

 

Cloud provider

Select the cloud provider to be used.

 

Action

Select the action you need tCloudStop to take in order to change the status of a given instance. This action may be:

  • Suspend

  • Resume

  • Terminate

Note that if you terminate an instance, this instance will be deleted, while a suspended instance can still be resumed.

 

Predicate

Select the instance(s) of which you need to change the status. The options are:

  • Running instances: status of all the running instances will be changed.

  • Instances in a specific group: status of the instances of a specific instance group will be changed. You need to enter the name of that group in the Group name field.

  • Running instances in a specific group: status of the running instances of a specific instance group will be changed. You need to enter the name of that group in the Group name field.

  • Instance with predefined id: status of a given instance will be changed. You need to enter the ID of that instance in the Id field. You can find this ID on your Amazon EC2.

An instance group is composed of the instances using the same instance name you have defined in the Instance name field of tCloudStart.

 

Group name

Enter the name of the group in which you want to change the status of given instances. This field appears when you select Instances in a specific group or Running instances in a specific group from the Predicate list.

 

Id

Enter the ID of the instance of which you need to change the status. This field appears when you select Instance with predefined id from the Predicate list.

Advanced settings

tStatCatcher Statistics

Select this check box to collect the log data at the component level.

Global Variables

ERROR_MESSAGE: the error message generated by the component when an error occurs. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl + Space to access the variable list and choose the variable to use from it.

For further information about variables, see Talend Studio User Guide.

Usage

This component works standalone to change the status of given instances on Amazon EC2. You can use this component to suspend, resume or terminate the instance(s) you have deployed Jobs on.

This component often works alongside tCloudStart to change the status of the instances launched by the latter component.
