How to specify an instance type creating an AWS EC2 instance with the RunInstancesRequest

Question

I would like to specify an instance type, ie “c4.large”, creating an AWS EC2 instance. The information about new instance is in RunInstanceRequest. How to specify an instance type creating an instance?

Answer 1

To specify the instance type in a RunInstancesRequest , you can use either:

• setInstanceType(String instanceType) , or
• setInstanceType(InstanceType instanceType)

For example:

r = new RunInstancesRequest();
r.setInstanceType('t1.micro');
r.setMinCount(1);
r.setMonitoring(true);

Note that there are also withInstanceType variants of these methods which allow you to chain initializer methods , for example:

r = new RunInstancesRequest()
    .withInstanceType('t1.micro')
    .withMinCount(1)
    .withMonitoring(true);
