我正在将 hello-world docker 容器部署到 k3d 集群。为了获取外部IP，部署了负载均衡器类型的服务。

之后我希望通过负载均衡器调用应用程序。但我没有得到外部IP。

k3d create --name="mydemocluster" --workers="2" --publish="80:80"

export KUBECONFIG="$(k3d get-kubeconfig --name='mydemocluster')"

kubectl run kubia --image=hello-world --port=8080 --generator=run/v1
kubectl expose rc kubia --type=LoadBalancer --name kubia-http

export KUBECONFIG="$(k3d get-kubeconfig --name='mydemocluster')"

然后 kubectl get services：

问题

使用 json 模式验证器验证 json 会引发加载 json 模式文件的异常：

• Json 架构版本草案 07： https: //json-schema.org/learn/miscellaneous-examples.html
  • lib贡献者已经测试了我的输入，因此验证器lib按预期工作：https://github.com/networknt/json-schema-validator/commit/236967ad478802233ddf1f5e277bf0903af47e5a
