public static EC2Instance getLocalEC2Instance()
                                       throws IOException

Returns:

The EC2Instance upon which the current JVM is hosted.

Throws:

IOException - if necessary data could not be read.

setUserData

public static void setUserData(@NotNull
                               com.amazonaws.services.ec2.model.LaunchSpecification launchSpecification,

                               Object userData)
                        throws IOException

AWS SDK variant for spot instances: Populates the user data of an EC2 with an object.

Parameters:

launchSpecification - The launchSpecification to populate

userData - The object to serialise

Throws:

IOException - If the object could not be serialised.

setUserData

public static void setUserData(@NotNull
                               com.amazonaws.services.ec2.model.RunInstancesRequest runInstancesRequest,
                               @Nullable
                               Object userData)

AWS SDK variant for regular instances: Populates the user data of an EC2 with an object.

Parameters:

runInstancesRequest - The launchSpecification to populate

userData - The object to serialise

Throws:

IOException - If the object could not be serialised.

getUserData

public static <T> T getUserData(Class<T> aClass)
                     throws IOException,

Retrieves a serialised object from the EC2 user data for the current host.

Returns:

The retrieved object.

Throws:

IOException - If the user data could not be read or deserialised.

ClassNotFoundException - If a required Class could not be found.

getCurrentImage

public static EC2Image getCurrentImage()
                                throws IOException

Returns:

The EC2Image upon which the current process is running.

Throws:

IOException - If the EC2Image cannot be identified, possibly because the current process is not running in EC2.
