Amazon EC2 - Allocate address
<AMAWSEC2 ACTIVITY="allocate_address" RESULTVARIABLE="text" ACCESSKEY="text" SECRETKEY="text (encrypted)" SERVICEURL="text" PROXYHOST="text" USERAGENT="text" PROXYPORT="number" PROXYUSER="text" PROXYPWD="text (encrypted)" MAXERRORRETRY="number" SIGNMETHOD="text" SIGNVERSION="number" />
Description: Allocates an EC2 elastic IP address and populates a variable with results.
Practical Usage
Typically used to acquire an elastic IP address for use with your EC2 account. Elastic IP addresses are static IP addresses designed for dynamic cloud computing. Rather than waiting on a data technician to re-configure or replace your host or waiting for DNS to propagate to all of your customers, EC2 enables you to engineer around problems with your instance or software by programmatically remapping your Elastic IP address to a replacement instance.
Connection Parameters

Description |
|---|---|---|---|---|---|
|
Connection |
|
|
|
|
Indicates where user credentials and preferences should originate from. This is a design mode parameter used only during task construction and configuration, thus, comprises no markup. The available options are:
|
|
Session |
Text |
Yes if connection is session-based |
EC2Session1 |
SESSION="EC2Session1" |
The name of an existing session to attach this activity to. This parameter is active only if the Connection parameter is set to Session. |
|
Access key |
Text |
Yes if connection is host-based |
(Empty) |
ACCESSKEY= "022QF06E7MXBSH9DHM02" |
A 20-character alphanumeric string that uniquely identifies the owner of the AWS service account, similar to a username. This key along with a corresponding secret access key forms a secure information set that AWS uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host. |
|
Secret Access key |
Text |
Yes if connection is host-based |
(Empty) |
SECRETKEY= "kWcrlUX5JEDGM/LtmEENI/ aVmYvHNif5zB+d9+ct" |
A 40-character string that serves the role as password to access the AWS service account. This along with an associated access key forms a secure information set that EC2 uses to confirm a valid user's identity. This parameter is active only if the Connection parameter is set to Host. |
|
User agent |
Text |
No |
AutoMate |
USERAGENT="AutoMate" |
The name of the client or application initiating requests to AWS. The default value is 'AutoMate'. |
|
Service URL |
Text |
No |
(Empty) |
SERVICEURL= "https://ec2.eu-west-1.amazonaws.com" |
The URL that provides the service endpoint. To make the service call to a different region, you can pass the region-specific endpoint URL. For example, entering https://ec2.us-west-1.amazonaws.com points to US West (Northern California) region. A complete list of EC2 regions, accompanying endpoints and valid protocols can be found below under EC2 Regions and Endpoints. |
|
Maximum retry on error |
Number |
No |
(Empty) |
MAXERRORRETRY="4" |
The total amount of instances this activity should retry the request before returning an error. Network components can generate errors anytime in the life of a request, thus, implementing retries can increase reliability. |
|
Signature method |
Text |
No |
(Empty) |
SIGNMETHOD="HmacSHA256" |
The signature method to use for signing the request. This provides a valid hashing algorithm for signature calculation. Valid AWS signature methods are HmacSHA1 and HmacSHA256. |
|
Signature version |
Number |
No |
(Empty) |
SIGNVERSION="2" |
The signature version for signing the request. Valid AWS signature versions are 2 and 4. The difference with version 4 is that it allows you to sign your message using a key that is derived from your secret access key rather than using the secret access key itself. |
Elastic IP Parameter
|
Property |
Type |

Description |
|---|---|---|---|---|---|
|
Populate variable with Elastic IP |
Text |
Yes |
(Empty) |
RESULTVARIABLE="theVarName" |
The name of an existing variable in which to populate the Elastic IP address with. |
Description tab - A custom description can be provided on the Description tab to convey additional information or share special notes about a task step.
Error Causes tab - Specify how this step should behave upon the occurrence of an error. (Refer to Task Builder > Error Causes Tab for details.)
On Error tab - Specify what AWE should do if this step encounters an error as defined on the Error Causes tab. (Refer to Task Builder > On Error Tab for details.)
