我正在尝试在 EKS (AWS Kubernetes) 上创建一个 Ingress 资源。

在做kubect get all时我有：

这是我的超级简单 YAML：

apiVersion: networking.k8s.io/v1beta1
  kind: Ingress
  metadata:
    annotations:
      kubernetes.io/ingress.class: nginx
    name: <ommited>
    namespace: default
  spec:
    rules:
        http:
          paths:
            - backend:
                serviceName: auth-demo
                servicePort: 8080
              path: /

我得到：error: error parsing deployment.yaml: error converting YAML to JSON: yaml: line 2: mapping values are not allowed in this context kubectl apply -f deployment.yaml。

有人知道诊断方法吗？谢谢！

【解决方案1】：

yaml 中存在缩进问题，以下应该可以工作。

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: test-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
  namespace: default
spec:
  rules:
  - http:
      paths:
      - path: /
        backend:
          serviceName: auth-demo
          servicePort: 8080
