Amazon EC2 - Create key pair |
Declaration
<AMAWSEC2 ACTIVITY="create_keypair" PROVIDER="session_based" SESSION="text" ACCESSKEY="text" SECRETKEY="text (encrypted)" USERAGENT="text" MAXERRORRETRY="number" SERVICEURL="text" PROXYHOST="text" PROXYPORT="number" PROXYUSER="text" PROXYPWD="text (encrypted)" SIGNMETHOD="text" SIGNVERSION="number" KEYPAIR="text" FILE="text" OVERWRITEFILE="YES/NO" />
Description
Creates a new 2048-bit RSA key pair with the specified name. The public key is stored by Amazon EC2 and the private key is saved to the file path you specify. The private key is returned as an unencrypted PEM encoded PKCS#8 private key.
Practical Usage
Used to create an EC2 key pair in order to launch an Amazon AMI. If a key with the specified name already exists, Amazon EC2 returns an error. The key pair returned works only in the region you're using when you create the key pair.
Parameters
Connection
Property | Type | Required | Default | Markup | Description |
---|---|---|---|---|---|
Connection | --- | --- | --- | --- | Indicates
where user credentials and preferences originate from.
This parameter does not contain markup and is only displayed in visual mode for task construction and configuration purposes. The available options
are:
|
Session | Text | Yes, if the connection is set to Session | 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 the connection is set to Host | (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 the connection is set to Host | (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'. |
Maximum number of retries 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. |
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. |
Proxy host | Text | No | (Empty) | PROXYHOST="proxy.host.com" | The host name (for example, server.domain.com) or IP address (for example, xxx.xxx.xxx.xxx) of the proxy server to use when connecting to AWS. |
Proxy port | Number | No | (Empty) | PROXYPORT="1028" | The port number to use to connect to the proxy server. |
Proxy username | Text | No | (Empty) | PROXYUSERNAME="Username" | The username to authenticate with the proxy server. |
Proxy password | Text | No | (Empty) | PROXYPWD="encrypted" | The password to authenticate with 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. |
Key Pair
Property | Type | Required | Default | Markup | Description |
---|---|---|---|---|---|
Key pair name | Text | Yes | (Empty) | KEYPAIR="mysecretkey" | A unique name to assign for the key pair in which to create. |
File path | Text | Yes | (Empty) | FILE="C:\Temp\KeyPair.pem" | The full path and file name in which to store the new key pair file (.pem extension). |
Overwrite if file exists | Yes/No | No | No | OVERWRITE="YES" | If selected, files with matching names that exist in the destination are overwritten. If disabled, files with matching names are not overwritten, but an error occurs as a result. The default value is NO. |
