我的应用程序有问题。我的服务器上有 microk8s，我正在尝试部署应用程序。我编写了部署、入口和服务文件。deploy.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: my-nginx
spec:
replicas: 1
selector:
matchLabels:
run: my-nginx
template:
metadata:
labels:
run: my-nginx
spec:
containers:
- name: my-nginx
image: nginx
ports:
- containerPort: 80
入口文件
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: learn-linux.eu
annotations:
kubernetes.io/ingress.class: "nginx"
spec:
rules:
- host: learn-linux.eu
http:
paths:
- path: /
backend:
serviceName: nginx-service
servicePort: 80
服务.yaml
apiVersion: v1
kind: Service
metadata:
name: nginx-service
labels:
app: my-nginx
spec:
ports:
- port: 80
protocol: TCP
selector:
app: my-nginx
域记录 A 已更改为我拥有 microk8s 的服务器 IP。但是当我执行 curl learn-linux.eu 时，我得到：
curl：（7）无法连接到本地主机端口 80：连接被拒绝
但是当我对 pod IP 执行 curl 命令时，我收到 nginx 默认页面
root@learn-linux:~# curl 10.1.31.22
