Gradle で Amazon EC2 を操作してみる

build.gradle

import com.amazonaws.services.ec2.model.*;

buildscript {
    repositories { mavenCentral() }
    dependencies { classpath 'com.amazonaws:aws-java-sdk:1.1.9' }
}

def credentials = new PropertiesCredentials(
                        new File(System.properties['user.home'],
                                 '.aws/AwsCredentials.properties'))

def ec2 = new AmazonEC2Client(credentials)
if (hasProperty('region')) ec2.endpoint = "https://ec2.${region}.amazonaws.com"


task 'start' << {
    ec2.startInstances(new StartInstancesRequest([instanceId]))
}

task 'stop' << {
    ec2.stopInstances(new StopInstancesRequest([instanceId]))
}

task 'status' << {
    desc = ec2.describeInstances(new DescribeInstancesRequest().withInstanceIds([instanceId]))
    inst = desc.reservations[0].instances[0]
    println "${inst.state.name}: ${inst.publicDnsName}"
}
