Amazon EC2 - Reboot Instance

Declaration

<AMAWSEC2 ACTIVITY="reboot_instance" INSTANCEID="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:

Requests a reboot of an instance. The operation will succeed if the instances are valid and belong to you. Requests to reboot terminated instances are ignored.

IMPORTANT: The AWS EC2 activities are performed using Amazon's EC2 engine, therefore, launching and administering Amazon EC2 instances through requires a valid Access Key ID and Secret Access Key.

Practical Usage

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:

  • Host (default) - Specifies that user credentials and/or advanced preferences are configured individually for this activity. Normally chosen if only a single activity is required to complete an operation.

  • Session - Specifies that user credentials and/or advanced preferences are obtained from a pre-configured session created in an earlier step with the use of the EC2 - Create session activity. Normally chosen if a combination of activities within the same action group are required. Linking several activities to a single session eliminates redundancy and improves efficiency. Several sessions can exist in a single task. Multiple sessions can run simultaneously without interference.

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.eu-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)

  1. PROXYHOST="proxy.host.com"

  2. PROXYHOST="193.118.431.52"

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.

Instance

Property

Type

Required

Default

Markup

Description

Instance ID

Text

Yes

(Empty)

INSTANCEID="i-3711a35c"

The unique ID of the instance to reboot.
