Compute

Create a cloud

Here's an example using DigitalOcean:

final CsCloudConfig config = new CsCloudConfig()
        .withAccountId(accountId)
        .withAccountSecret(accountSecret)
        .withRegion("sfo1")
        .withInstanceSize("2gb")
        .withImage("ubuntu-14-04-x64")
        .withGroupPrefix("mygroup-")
        .withProvider(JcloudBase.PROVIDER_DIGITALOCEAN)
        .withUser("ubuntu")
        .withDomain("example.com")
        .withCloudClass(DigitalOceanCloud.class.getName());

final CsCloud cloud = new CsCloudFactory().buildCloud(config);

Start an instance

final CsInstanceRequest request = new CsInstanceRequest().withHost("foo")
final CsInstance instance = cloud.newInstance(request);

This will create a new instance. On the new instance, an ssh keypair will be created to allow password-less login for the "user" configured for the cloud. This user will also be granted password-less sudo privileges. The hostname of the instance will be set to the hostname on the instance request + the domain name set on the cloud.

Run a command on the instance and return the output

cloud.execute(instance, "echo \"my username is $(whoami)\"");

Copy files to the instance

try (InputStream in = new FileInputStream("/some/local/file")) {
    cloud.scp(instance, in, "/destination/path/on/instance");
}

Destroy the instance

cloud.teardown(instance);

Storage

Encryption is built-in, using dataKey as the secret.

final S3StorageEngineConfig config = new S3StorageEngineConfig();
config.setAccessKey(accessKey);
config.setSecretKey(secretKey);
config.setBucket(bucket);
config.setUsername(username);
config.setDataKey(dataKey);  // encryption key S3 object read/write

final CsStorageEngine storage = CsStorageEngineFactory.build(config);

byte[] data = storage.read("/some/path");
storage.write("/some/other/path", data);
