azure - 列出 Azure 云中的所有实例终结点

Question

如何列出 Azure 云中的所有端点，而不仅仅是当前角色实例上的端点？

我已尝试以下代码，但它仅列出当前 Azure 实例上的端点，而不列出任何其他 Azure 实例上的端点:

void ListCloudInstances()
{
    var instances = new StringBuilder("");

    foreach (var role in RoleEnvironment.Roles)
    {
        instances.AppendFormat("<h2>Role <em>{0}</em></h2><br/>", role.Value.Name);
        if (role.Value.Instances.Count == 0)
            instances.AppendFormat("<small>Role <em>{0}</em> has no role instances</small><br/><br/>", role.Value.Name);

        foreach (var roleInstance in role.Value.Instances)
        {
            var currentRoleMarker = RoleEnvironment.CurrentRoleInstance.Id == roleInstance.Id ? " *" : String.Empty;
            instances.AppendFormat("<h3>Role <em>{2}</em> instance <em>{0}</em>{1}</h3><br/>", 
                roleInstance.Id, currentRoleMarker, roleInstance.Role.Name);

            // List some metadata about the role instance
            instances.AppendFormat("<p>Role instance fault domain: {0}</p>", roleInstance.FaultDomain);
            instances.AppendFormat("<p>Role for the instance: {0}</p>", roleInstance.Role.Name);
            instances.AppendFormat("<p>Role instance update domain: {0}</p><br/>", roleInstance.UpdateDomain);

            // List the endpoints
            instances.AppendFormat("<h4>Role <em>{1}</em> instance <em>{0}</em> endpoints</h4><br/>", roleInstance.Id,
                roleInstance.Role.Name);

            foreach (RoleInstanceEndpoint instanceEndpoint in roleInstance.InstanceEndpoints.Values)
            {
                if (roleInstance.Role.Name == "Www")
                    instances.AppendFormat("<p><a href=\"{0}://{1}/Admin/Settings.aspx\" target=\"_blank\">{1}</a></p>", 
                        instanceEndpoint.Protocol, instanceEndpoint.IPEndpoint);
                else instances.AppendFormat("<p>Instance endpoint IP address, port, and protocol : {0} {1}</p>",
                    instanceEndpoint.IPEndpoint, instanceEndpoint.Protocol);
            }
        }
    }

    instances.AppendFormat("<small>* Current role instance is {0}</small>", RoleEnvironment.CurrentRoleInstance.Id);

    CloudHtml.Text = instances.ToString();
}

在每个角色都有多个实例的多角色项目上运行的输出:

Role MultiThreadedWorkerRole

Role MultiThreadedWorkerRole has no role instances

Role Www

Role Www instance deployment22(203).CloudService1.Www_IN_1 *

Role instance fault domain: 1

Role for the instance: Www

Role instance update domain: 1

Role Www instance deployment22(203).CloudService1.Www_IN_1 endpoints

127.255.0.3:82

127.255.0.3:444

• Current role instance is deployment22(203).CloudService1.Www_IN_1

如果我重新运行上述查询，我​​会随机获取从角色实例deployment22(203).CloudService1.Www_IN_0到deployment22(203).CloudService1.Www_IN_4的输出，具体取决于处理 ASP.NET Web 表单的实例运行上面的代码片段。示例:

Role MultiThreadedWorkerRole

Role MultiThreadedWorkerRole has no role instances

Role Www

Role Www instance deployment22(203).CloudService1.Www_IN_0 *

Role instance fault domain: 0

Role for the instance: Www

Role instance update domain: 0

Role Www instance deployment22(203).CloudService1.Www_IN_0 endpoints

127.255.0.2:82

127.255.0.2:444

• Current role instance is deployment22(203).CloudService1.Www_IN_0

Answer 1

我相信关键在于 documentation of the RoleEnvironment's Roles property 上所做的以下注释-

At least one internal endpoint must be defined for a role to enable instances to be known at runtime

我刚刚尝试过创建一个具有两个角色的云项目，并使用 RoleEnvironment.Roles 迭代这些角色，没有任何内部端点，只有当前角色的实例可用。

将内部端点添加到其他角色后，它的实例已为我加载。但是 - 角色实例的 InstanceEndpoints 集合中仅列出了内部端点。我看不到他们公开的外部端点。
