在多命名空间集群 AKS 中使用入口

Question

我有一个集群，我为不同的团队创建了命名空间。然后，我尝试使用此命令 kubectl apply -f ing2_dev_plat.yaml -n namespace_name.

将入口应用到一个命名空间

之后，抛出了这个错误。如何在多个命名空间中正确配置入口控制器的工作？

Nginx 入口控制器服务在默认命名空间中。

Answer 1

正如我在问题下的评论中所说：

nginx: [emerg] duplicate location "/" in /tmp/nginx-cfg1414424955:1045

可能表示您对同一位置定义了两次。

如果您有任何其他 Ingress 资源 path: /，您必须相应地编辑它们。

您可以通过

获取所有 Ingress 资源及其路径

kubectl get ingress -A -o=jsonpath='{range .items[*]}{.metadata.name}{"\t"}{.spec.rules[*].http.paths[*].path}{"\n"}{end}'
