tCloudStop – Docs for ESB 7.x

tCloudStop

Changes the status of a launched instance on Amazon EC2 (Amazon Elastic Compute
Cloud).

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

tCloudStop Standard properties

These properties are used to configure tCloudStop running in the Standard Job framework.

The Standard
tCloudStop component belongs to the Cloud family.

The component in this framework is available in all Talend
products
.

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 whose security group name or key pair name is set to
jclouds#<$group_name> in the
tCloudStart component, where
<$group_name> identifies the group to which the
instance belongs.

This field is available only when Instances in a
specific group
or Running instances
in a specific group
is selected from the Predicate list.

Id

Enter the ID of the instance of which you need to change the
status, for
instance, “${region}/${instance id}”. 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

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

Usage rule

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.

No scenario is available for the Standard version of this component yet.
