Question

因此，在此处进行详细说明以更好地进行说明。我的服务由专用名称空间中的以下属性组成（不使用ServiceEntry）

部署（1个部署）
配置映射（1个配置映射）
服务
VirtualService
GW

在命名空间中启用了Istio，当我创建/运行部署时，它会按需创建2个容器。现在，正如问题主题中所述，我希望允许所有传出流量进行部署，因为我的服务需要连接2个服务发现服务器：

在端口8200上运行的保管库
spring配置服务器
下载依赖项并与其他服务（不属于vpc / k8的一部分）通信

使用以下部署文件将不会打开传出连接。 https request on port 443唯一有效的方法是简单的，就像我运行curl https://google.com时成功但对curl http://google.com没有响应一样。显示与Vault的连接的日志也没有建立。

我几乎在部署中使用了所有组合，但似乎都不起作用。我有什么想念的或者做错了吗？非常感谢在此方面的贡献:)
