我正在尝试在 minikube 上运行 ingress。 我在 ubnutu 18.04 上运行。 我对 nginx-ingress 感兴趣: https://kubernetes.github.io/ingress-nginx/deploy/
我有一个简单的测试服务，它在 docker 容器内的端口 3000 上运行。该容器被推送到 docker hub。我有简单的获取请求:
app.get('/api/users/currentuser', (req, res) => {
res.send('Hi there!');
});
我已经完成的步骤:minikube start 然后minikube addons enable ingress 之后我收到来自 minikube 的消息:
🔎 Verifying ingress addon...
🌟 The 'ingress' addon is enabled
但当我尝试验证它是否正在运行时，我认为这工作正常: 来自 kubectl get pods -n kube-system
的输出NAME READY STATUS RESTARTS AGE

执行kubectl get pods时也没有关于入口的信息

我正在使用命令 skaffold dev 通过 skaffold 运行服务
入口服务的配置如下所示:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress-service
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/use-regex: 'true'
spec:
rules:
- host: kube-test.dev
http:
paths:
- path: /api/users/?(.*)
backend:
serviceName: auth-srv
servicePort: 3000
指向部署文件(kube-test.dev 的主机刚刚映射到 /etc/hosts 中的本地主机):
apiVersion: apps/v1
kind: Deployment
metadata:
name: auth-depl
spec:
replicas: 1
selector:
matchLabels:

kind: Service
metadata:
name: auth-srv
spec:
selector:
app: auth
ports:
- name: auth
protocol: TCP
port: 3000
targetPort: 3000
更重要的是，如果这确实重要，skaffold 配置如下所示:
apiVersion: skaffold/v2alpha3
kind: Config
deploy:
kubectl:
manifests:
- ./infra/k8s/*
build:
local:
push: false
artifacts:
- image: geborskimateusz/auth
context: auth
docker:
dockerfile: Dockerfile
sync:
manual:
- src: 'src/**/*.ts'
dest: .
这里有什么想法吗？我在 mac 上运行类似的配置并且运行良好，这看起来更像是入口插件问题。这里有什么想法吗？
当我点击kube-test.dev/api/users/currentuser时，我得到:
Error: connect ECONNREFUSED 127.0.0.1:80
和主机文件:
127.0.0.1 localhost
127.0.1.1 mat-5474
# The following lines are desirable for IPv6 capable hosts

最佳答案
运行 minikube ip。 您将获得一个 IP 地址，将其复制粘贴到 kube-test.dev 的 etc/hosts 文件中
