在项目中增加maven依赖包
org.pacesys openstack4j 3.0.3 withdeps
通过权限认证
import org.openstack4j.api.OSClient.OSClientV3;import org.openstack4j.openstack.OSFactory;import org.openstack4j.model.common.Identifier; # use Identifier.byId("domainId") or Identifier.byName("example-domain") Identifier domainIdentifier = Identifier.byId("domainId"); # unscoped authentication # as the username is not unique across domains you need to provide the domainIdentifier OSClientV3 os = OSFactory.builderV3() .endpoint("http://127.0.0.1:5000/v3") .credentials("admin","sample", domainIdentifier) .authenticate(); # project scoped authentication OSClientV3 os = OSFactory.builderV3() .endpoint("http://127.0.0.1:5000/v3") .credentials("admin", "secret", Identifier.byName("example-domain")) .scopeToProject(Identifier.byId(projectIdentifier)) .authenticate(); # domain scoped authentication # using the unique userId does not require a domainIdentifier OSClientV3 os = OSFactory.builderV3() .endpoint("http://127.0.0.1:5000/v3") .credentials("userId", "secret") .scopeToDomain(Identifier.byId(domainIdentifier)) .authenticate(); # Scoping to a project just by name isn't possible as the project name is only unique within a domain. # You can either use this as the id of the project is unique across domains OSClientV3 os = OSFactory.builderV3() .endpoint("http://127.0.0.1:5000/v3") .credentials("userId", "secret") .scopeToProject(Identifier.byName(projectName), Identifier.byName(domainName)) .authenticate(); # Or alternatively OSClientV3 os = OSFactory.builderV3() .endpoint("http://127.0.0.1:5000/v3") .credentials("userId", "secret") .scopeToDomain(Identifier.byName(domainName)) .authenticate();
常用模块调用
// Find all UsersList extends User> users = os.identity().users().list();// List all TenantsList extends Tenant> tenants = os.identity().tenants().list();// Find all Compute FlavorsList extends Flavor> flavors = os.compute().flavors().list();// Find all running ServersList extends Server> servers = os.compute().servers().list();// Suspend a Serveros.compute().servers().action("serverId", Action.SUSPEND);// List all NetworksList extends Network> networks = os.networking().network().list();// List all SubnetsList extends Subnet> subnets = os.networking().subnet().list();// List all RoutersList extends Router> routers = os.networking().router().list();// List all Images (Glance)List extends Image> images = os.images().list();// Download the Image DataInputStream is = os.images().getAsStream("imageId");
