A note about referencing Snapshots without Source

Snapshots are deploys to sonatype. You will need to add the repository to your POM or Settings file. Releases (above) are deployed to maven central and this step is not required.

Example POM based repository declaration to grab snapshots:

<repositories>
    <repository>
      <id>st-snapshots</id>
      <name>sonatype-snapshots</name>
      <url>https://oss.sonatype.org/content/repositories/snapshots</url>
    </repository>

Quick Usage Guide

Below are some examples of the API usage. Please visit www.OpenStack4j.com for the full manual and getting started guides.

Authenticating

OpenStack4j 3.0.0+ supports Identity (Keystone) V3 and V2.

OpenStack4j 3.0.0 introduced some breaking changes. The legacy Identity V2 API now uses the class OSClientV2 in place of the class OSClient.

Using Identity V2 authentication:
// Identity V2 Authentication Example
OSClientV2 os = OSFactory.builderV2()
                       .endpoint("http://127.0.0.1:5000/v2.0")
                       .credentials("admin","sample")
                       .tenantName("admin")
                       .authenticate();
Using Identity V3 authentication

Creating and authenticating against OpenStack is extremely simple. Below is an example of authenticating which will result with the authorized OSClient. OSClient allows you to invoke Compute, Identity, Neutron operations fluently.

You can use either pass the users name or id and password in the following way

.credentials("username", "secret", Identifier.byId("domain id"))

or

.credentials("user id", "secret")

to provide credentials in each of the following cases.

Using Identity V3 authentication you basically have 4 options:

(1) authenticate with project-scope

OSClientV3 os = OSFactory.builderV3()
                .endpoint("http://<fqdn>:5000/v3")
                .credentials("admin", "secret", Identifier.byId("user domain id"))
                .scopeToProject(Identifier.byId("project id"))
                .authenticate());

(2) authenticate with domain-scope

OSClientV3 os = OSFactory.builderV3()
                .endpoint("http://<fqdn>:5000/v3")
                .credentials("admin", "secret", Identifier.byId("user domain id"))
                .scopeToDomain(Identifier.byId("domain id"))
                .authenticate());

(3) authenticate unscoped

OSClientV3 os = OSFactory.builderV3()
                .endpoint("http://<fqdn>:5000/v3")
                .credentials("user id", "secret")
                .authenticate();

(4) authenticate with a token

OSClientV3 os = OSFactory.builderV3()
                .endpoint("http://<fqdn>:5000/v3")
                .token("token id")
                .scopeToProject(Identifier.byId("project id"))
                .authenticate());

Identity Operations (Keystone) V3

After successful v3 - authentication you can invoke any Identity (Keystone) V3 directly from the OSClientV3.

Identity Services fully cover User, Role, Project, Domain, Group,.. service operations (in progess).
The examples below are only a small fraction of the existing API so please refer to the API documentation for more details.

NOTE: The os used here is an instance of org.openstack4j.api.OSClient.OSClientV3.

User operations

// Create a User associated to the new Project
User user = os.identity().users().create(Builders.user()
													.domainId("domain id")
													.name("foobar")
													.password("secret")
													.email("[email protected]")
													.enabled(true)
													.build());
//or
User user = os.identity().users().create("domain id", "foobar", "secret", "[email protected]", true);

// Get detailed info on a user by id
User user = os.identity().users.get("user id");
//or by name and domain identifier
User user = os.identity().users.getByName("username", "domain id");

// Add a project based role to the user
os.identity().roles().grantProjectUserRole("project id","user id", "role id");

// Add a domain based role to the user
os.identity().roles().grantDomainUserRole("domain id","user id", "role id");

// Add a user to a group
os.identity().users().addUserToGroup("user id", "group id");

Role operations

// Get a list of all roles
os.identity().roles().list();

// Get a role by name
os.identity().roles().getByName("role name);

Project operations

// Create a project
os.identity().project().create(Builders.project()
											.name("project name")
											.description("project description")
											.domainId("project domain id")
											.enabled(true)
											.build());

Identity Operations (Keystone) V2

After successful v2 - authentication you can invoke any Identity (Keystone) V2 directly from the OSClientV2.

Identity V2 Services fully cover Tenants, Users, Roles, Services, Endpoints and Identity Extension listings. The examples below are only a small fraction of the existing API so please refer to the API documentation for more details.

NOTE: The os used here is an instance of org.openstack4j.api.OSClient.OSClientV2.

Create a Tenant, User and associate a Role

// Create a Tenant (could also be created fluent within user create)
Tenant tenant = os.identity().tenants().create(Builders.tenant().name("MyNewTenant").build());

// Create a User associated to the new Tenant
User user = os.identity().users().create(Builders.user().name("jack").password("sample").tenant(tenant).build());

// Add a Tenant based Role to the User
os.identity().roles().addUserRole(tenant.getId(), user.getId(), os.identity().roles().getByName("Member").getId());

Compute Operations (Nova)

OpenStack4j covers most the major common compute based operations. With the simplistic API approach you can fully manage Servers, Flavors, Images, Quota-Sets, Diagnostics, Tenant Usage and more. As the API evolves additional providers and extensions will be covered and documented within the API.

Create a Flavor and Boot a Server/VM

// Create a Flavor for a special customer base
Flavor flavor = os.compute().flavors()
                  .create(Builders.flavor().name("Gold").vcpus(4).disk(80).ram(2048).build());

// Create and Boot a new Server (minimal builder options shown in example)
Server server = os.compute().servers()
                  .boot(Builders.server().name("Ubuntu 2").flavor(flavor.getId()).image("imageId").build());

Create a new Server Snapshot

String imageId = os.compute().servers().createSnapshot(server.getId(), "Clean State Snapshot");

Server Diagnostics

Diagnostics are usage information about the server. Usage includes CPU, Memory and IO. Information is dependant on the hypervisor used by the OpenStack installation. As of right now there is no concrete diagnostic specification which is why the information is variable and in map form (key and value)

Map<String, ? extends Number> diagnostics = os.compute().servers().diagnostics("serverId");

Networks (Neutron)

Network Operations

// List the networks which the current authorized tenant has access to
List<? extends Network> networks = os.networking().network().list();

// Create a Network
Network network = os.networking().network()
                    .create(Builders.network().name("MyNewNet").tenantId(tenant.getId()).build());

Subnet Operations

// List all subnets which the current authorized tenant has access to
List<? extends Subnet> subnets = os.networking().subnet().list();

// Create a Subnet
Subnet subnet = os.networking().subnet().create(Builders.subnet()
                  .name("MySubnet")
                  .networkId("networkId")
                  .tenantId("tenantId")
                  .addPool("192.168.0.1", "192.168.0.254")
                  .ipVersion(IPVersionType.V4)
                  .cidr("192.168.0.0/24")
                  .build());

Router Operations

// List all Routers
List<? extends Router> = os.networking().router().list();

// Create a Router
Router router = os.networking().router().create(Builders.router()
                  .name("ext_net").adminStateUp(true).externalGateway("networkId").build());

Image Operations (Glance)

Basic Operations

// List all Images
List<? extends Image> images = os.images().list();

// Get an Image by ID
Image image = os.images().get("imageId");

// Delete a Image
os.images().delete("imageId");

// Update a Image
Image image = os.images().get("imageId");

os.images().update(image.toBuilder()
           .name("New VM Image Name").minDisk(1024).property("personal-distro", "true"));

Download the Image Data

InputStream is = os.images().getAsStream("imageId");

Create a Image

// (URL Payload in this example, File, InputStream are other payloads available)
Image image = os.images().create(Builders.image()
                .name("Cirros 0.3.0 x64")
				.isPublic(true)
				.containerFormat(ContainerFormat.BARE)
				.diskFormat(DiskFormat.QCOW2)
				.build()
				), Payloads.create(new URL("https://launchpad.net/cirros/trunk/0.3.0/+download/cirros-0.3.0-x86_64-disk.img")));
