如何使用Terraform的kubernetes_ingress_v1配置多主机Ingress

直接对应你给出的Kubernetes Ingress配置，Terraform的kubernetes_ingress_v1资源写法如下：

resource "kubernetes_ingress_v1" "ingress_wildcard_host" {
  metadata {
    name = "ingress-wildcard-host"
  }

  spec {
    rule {
      host = "foo.bar.com"
      http {
        path {
          path      = "/bar"
          path_type = "Prefix"

          backend {
            service {
              name = "service1"
              port {
                number = 80
              }
            }
          }
        }
      }
    }

    rule {
      host = "*.foo.com"
      http {
        path {
          path      = "/foo"
          path_type = "Prefix"

          backend {
            service {
              name = "service2"
              port {
                number = 80
              }
            }
          }
        }
      }
    }
  }
}

关键对应说明： #

• metadata.name 对应K8s Ingress的metadata.name
• 每个spec.rule块对应K8s里的一条rules规则，host字段直接支持通配符格式*.foo.com
• 每个http.path块对应路径配置，path_type对应K8s的pathType
• backend.service块里的name和port.number分别对应后端服务的名称和端口号
