介绍两种OpenStack-API(Java版)——jcoulds && openstack4j
jclouds -该API提供云计算环境的可移植抽象层以及云规范特性,支持包括 Amazon, VMWare, Azure, and OpenStack 等云计算平台,其中针对OpenStack,目前支持Nova、cinder、glance、Neutron、Keystone、swift等API接口,但是不支持Ceilometer的API接口。
官方文档——强烈推荐
http://jclouds.apache.org/guides/openstack/
jcloudsjar包使用maven安装下载管理即可;
import com.google.common.collect.ImmutableSet;
import com.google.common.io.Closeables;
import com.google.inject.Module;
import org.jclouds.ContextBuilder;
import org.jclouds.logging.slf4j.config.SLF4JLoggingModule;
import org.jclouds.openstack.nova.v2_0.NovaApi;
import org.jclouds.openstack.nova.v2_0.domain.Server;
import org.jclouds.openstack.nova.v2_0.features.ServerApi;
import java.io.Closeable;
import java.io.IOException;
import java.util.Set;
public class JCloudsNova implements Closeable {
private final NovaApi novaApi;
private final Set<String> regions;
public static void main(String[] args) throws IOException {
JCloudsNova jcloudsNova = new JCloudsNova();
try {
jcloudsNova.listServers();
jcloudsNova.close();
} catch (Exception e) {
e.printStackTrace();
} finally {
jcloudsNova.close();
}
}
public JCloudsNova() {
Iterable<Module> modules = ImmutableSet.<Module>of(new SLF4JLoggingModule());
String provider = "openstack-nova";
String identity = "demo:demo"; // 项目管理员和用户
String credential = "devstack";// 用户密码
novaApi = ContextBuilder.newBuilder(provider)
.endpoint("http://xxx.xxx.xxx.xxx:5000/v2.0/")//API地址
.credentials(identity, credential)
.modules(modules)
.buildApi(NovaApi.class);
regions = novaApi.getConfiguredRegions();
}
private void listServers() {
for (String region : regions) {
ServerApi serverApi = novaApi.getServerApi(region);
System.out.println("Servers in " + region);
for (Server server : serverApi.listInDetail().concat()) {
System.out.println(" " + server);
}
}
}
public void close() throws IOException {
Closeables.close(novaApi, true);
}
}
比较稳定,而且API文档很全,教好理解;
针对OpenStack的Web-API,包含Keystone、Nova、Neutron、Glance、Cinder
、Swift、Ceilometer、Heat的API支持,更新速度快,有问题需求及时联系Github可以得到解决。
官方文档——http://www.openstack4j.com/learn/

OpenStack4j -jar包使用提供的 openstack4j-2.0.1-withdeps-sources.jar即可,注意使用的jdk最好为1.7以上,jdk1.7最佳。java ee 5 或Java ee 6 均可。(使用Myeclipse时,jdk版本为1.6,容易报 version 51 错误。)
List<String> openStackNetworkList=new ArrayList<String>();
openStackNetworkList.add("df6effa2-a1b5-400a-8ab1-457673591aa1");
String openstackImageId = ""
String openstackFlavorId= "";
String openstackServerName = "";
String openstackZone = "nova:compute2";
ServerCreate sc = Builders.server().name(openstackServerName)
.flavor(openstackFlavorId)
.image(openstackImageId)
.networks(openStackNetworkList)
.availabilityZone(openstackZone)
.build();
// Boot the Server
OSClient os = OSFactory.builder()
.endpoint("http://x.x.x.x:5000/v2.0/")
.credentials("xxx","xxx")
.tenantName("xxx")
.authenticate();
Server server = os.compute().servers().boot(sc);
API简单易用;而且支持Ceilometer和Heat,推荐使用。
