kubernetes - Istio允许所有出站流量

因此，请在此处详细说明所有内容以便更好地进行说明。我的服务由专用命名空间中的以下属性组成(不使用ServiceEntry)

部署(1个部署)

Configmaps(1 configmap)

服务

虚拟服务

Istio已在 namespace 中启用，当我创建/运行部署时，它会按需创建2个容器。现在，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

在http 上运行的

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。唯一有效的方法就是简单的https request on port 443，例如当我运行curl https://google.com成功时，但对curl http://google.com没有响应。显示与Vault的连接的日志也未建立。

我几乎在部署中使用了所有组合，但似乎没有一个可行。我有什么想念的或者做错了吗？非常感谢在此做出的贡献:)

问题是我试图通过在pod中添加sidecar而不是在pod中添加来解决问题。从这里获得帮助:
