Amazon EC2 - Create session
Declaration
<AMAWSEC2 ACTIVITY="create_session" ACCESSKEY="text" SECRETKEY="text (options)" PROXYHOST="text" USERAGENT="text" PROXYPORT="number" PROXYUSER="text" PROXYPWD="text (options)" MAXERRORRETRY="number" SIGNMETHOD="text" SIGNVERSION="number" SESSION="text" />
Description: Creates a unique session which can be used to associate subsequent Amazon EC2 (Elastic Compute Cloud) steps. This provides a single task the ability to execute numerous EC2 operations associated to a specific session.
Practical Usage
Ideally used to create a session to correlate subsequent Amazon EC2 activities to. Creating a session eliminates having to re-enter specific requirements for each activity.

Description |
|---|---|---|---|---|---|
|
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. |
|
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. |
|
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. |
|
Proxy host |
Text |
No |
(Empty) |
|
The host name (e.g., server.domain.com) or IP address (e.g., xxx.xxx.xxx.xx) of the proxy server to use when connecting to AWS. |
|
Proxy port |
Number |
No |
(Empty) |
PROXYPORT="1028" |
The port that should be used to connect to the proxy server. |
|
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. |
|
Session Name |
Text |
Yes |
EC2Session1 |
SESSION="EC2Session1" |
The session name to be created. This allows several EC2 activities to be linked to this session, eliminating redundancy. Numerous sessions can be used within a single task. The default value is EC2Session1. NOTE: Use the End Session activity to end an EC2 session. |
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.)
