Question

我已经在裸机上安装了Kubernetes，并弄清楚了如何使用Ingress并将主机路由到我的服务。

但是当我对不同的主机使用相同的配置时，会得到default backend - 404。

工作配置：

apiVersion: v1
kind: Namespace
metadata:
    name: k8s-mariyo-host-1-sk-node-hello-world

---

apiVersion: v1
kind: Service
metadata:
    namespace: k8s-mariyo-host-1-sk-node-hello-world
    name: node-hello-world
    labels:
        app: node-hello-world
spec:
    ports:
        -   port: 80
            targetPort: 8080
    selector:
        app: node-hello-world

---

apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
    namespace: k8s-mariyo-host-1-sk-node-hello-world
    name: node-hello-world
spec:
    selector:
        matchLabels:
            app: node-hello-world
    strategy:
        type: Recreate
    template:
        metadata:
            namespace: k8s-mariyo-host-1-sk-node-hello-world
            labels:
                app: node-hello-world
        spec:
            containers:
                -   image: 10.100.100.1:5000/local-node-hello-world:1.5
                    name: hello-world
                    ports:
                        -   containerPort: 8080
                            name: hello-world

---

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
    namespace: k8s-mariyo-host-1-sk-node-hello-world
    name: node-hello-world
spec:
    rules:
        -   host: "node-hello-world.host-1.sk"
            http:
                paths:
                    -   path: /
                        backend:
                            serviceName: node-hello-world
                            servicePort: 80

默认后端-404配置：

apiVersion: v1
kind: Namespace
metadata:
    name: k8s-mariyo-host-2-sk-k8s

---

apiVersion: v1
kind: Service
metadata:
    namespace: k8s-mariyo-host-2-sk-k8s
    name: k8s
    labels:
        app: k8s
spec:
    ports:
        -   port: 80
            targetPort: 8080
    selector:
        app: k8s

---

apiVersion: apps/v1 # for versions before 1.9.0 use apps/v1beta2
kind: Deployment
metadata:
    namespace: k8s-mariyo-host-2-sk-k8s
    name: k8s
spec:
    selector:
        matchLabels:
            app: k8s
    strategy:
        type: Recreate
    template:
        metadata:
            namespace: k8s-mariyo-host-2-sk-k8s
            labels:
                app: k8s
        spec:
            containers:
                -   image: 10.100.100.1:5000/local-node-hello-world:1.5
                    name: k8s-hello
                    ports:
                        -   containerPort: 8080
                            name: k8s-hello

---

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
    namespace: k8s-mariyo-host-2-sk-k8s
    name: k8s
spec:
    rules:
        -   host: "k8s.host-2.sk"
            http:
                paths:
                    -   path: /
                        backend:
                            serviceName: k8s
                            servicePort: 80

有人能看到几乎相似的配置的奇怪/不同行为吗？这是差异链接：https://www.diffchecker.com/9AlnFQGz

正如@Mariyo在评论中提到的那样，问题似乎出在Cloudflare SSL配置上。如果您的网站不持有任何SSL证书，并且您考虑仅对Web用户和Cloudflare使用安全连接，而不对Web服务使用安全连接。然后，您可以选择Flexible SSL模式，而不是完全SSL严格模式。已经为任何进一步的贡献者研究提供了答案。

Kubernetes Ingress：为什么对于相同的配置，但是在不同的主机上，我会得到不同的结果？
