问题

  • 为什么使用localhost？
  • keystone与它有什么关系？
    • 我似乎无法配置一个keystone端点

上下文

  • App：Spring Boot（1.5.6）REST API
  • Hibernate 5.2
  • Hazelcast 3.9 - 仅限二级缓存
  • hazelcast-jclouds 3.7.1
  • jclouds-compute和jclouds-allcompute 2.0.2
  • 运行应用程序的虚拟机的Openstack云

设置

我的hazelcast.xml配置如下：

        <discovery-strategies>
            <discovery-strategy class="com.hazelcast.jclouds.JCloudsDiscoveryStrategy" enabled="true">
                <properties>
                    <property name="modules">org.jclouds.logging.slf4j.config.SLF4JLoggingModule</property>
                    <property name="provider">openstack-nova</property>
                    <property name="endpoint">http://dev.nova.cloud.youdontknow.net:8774/v2/</property>
                    <property name="identity">redacted</property>
                    <property name="credential">cens0red</property>
                </properties>
            </discovery-strategy>
        </discovery-strategies>

问题

应用初始化失败。这里有一些日志花絮：

[TRACE] o.j.r.internal.RestAnnotationProcessor   : looking up default endpoint for org.jclouds.openstack.keystone.v2_0.AuthenticationApi.public abstract org.jclouds.openstack.keystone.v2_0.domain.Access org.jclouds.openstack.keystone.v2_0.AuthenticationApi.authenticateWithTenantNameAndCredentials(java.lang.String,org.jclouds.openstack.keystone.v2_0.domain.PasswordCredentials)[bnet-web, PasswordCredentials{username=redacted, password=*****}]

[TRACE] o.j.rest.internal.InvokeHttpMethod       : << converted AuthenticationApi.authenticateWithTenantNameAndCredentials to POST http://localhost:5000/v2.0/tokens HTTP/1.1

此处的异常堆栈跟踪位：

其他注释

看起来它使用keystone中配置的默认org.jclouds.openstack.keystone.v2_0.KeystoneApiMetadata地址 - 但我不知道该如何参与。

答案 0 :(得分：2)

通过查看代码，我认为hazlecast-jclouds不准备管理通用API。连接到provider时，您不需要指定端点，因为它是众所周知的（AWS端点，Google，Azure等），但是当使用OpenStack或CloudStack等通用API时，需要告诉jclouds在哪里连接。不幸的是，看起来hazlecast-jclouds缺乏对通用API配置自定义端点的支持。

快速查看代码表明它可以很容易添加。考虑的属性在JCloudsDiscoveryStrategyFactory中定义，然后在ComputeServiceBuilder到create the jclouds context中阅读。

我不熟悉Hazlecast，但我会说添加“端点”属性的定义，然后，如果存在，通过调用jclouds contextBuilder.endpoint(endpoitn)方法来配置它应该可以解决问题。
