k8s ingres 的安装与使用

1. 安装. 从ingress的官网下载yaml文件.

https://raw.githubusercontent.com/kubernetes/ingress-nginx/master/deploy/static/mandatory.yaml

注意里面的iamges 的版本:

quay.io/kuberneftes-ingress-controller/nginx-ingress-controller:0.26.1

测试了下 不翻墙能够下载下来就是有点点慢

[root@k8smaster ~]# docker images
REPOSITORY                                                       TAG                 IMAGE ID            CREATED             SIZE
postgres                                                         latest              ee227fd504c8        3 days ago          348MB
quay.io/kubernetes-ingress-controller/nginx-ingress-controller   0.26.1              29024c9c6e70        2 weeks ago         483MB

2. 安装的话比较简单

kubectl apply -f mandatory.yaml

即可

注意修改增加修改一个 hostNetwork: true的才可以用

位置是在一个deployment 里面 images 的前面.

宋健鑫老师提供的解决思路 3ks alot

3. 简单的验证办法.

3.1 写一个最简单的nginx的 deployment文件

nginx-deployment.yaml

apiVersion: apps/v1beta2
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  selector:
    matchLabels:
      ingress-app: nginx
  replicas: 1
  template: 
    metadata:
      labels:
        ingress-app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx
        imagePullPolicy: IfNotPresent
        ports:
        - containerPort: 80

3.2 写一个svc文件

nginx-svc.yaml

apiVersion: v1
kind: Service
metadata:
  name: nginx-svc
  labels:
    app: nginx-svc
spec:
  ports:
    - port: 80
      targetPort: 80
      nodePort: 30080
      protocol: TCP
      name: http
  selector:
    ingress-app: nginx
  sessionAffinity: ClientIP
  type: NodePort

3.3 写一个ingress的配置文件

nginx-ingress.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: nginx-ingress
  namespace: default
spec:
  rules:
  - host: nginx.gscloud.club
    http:
      paths:
      - path: /
        backend:
          serviceName: nginx-svc
          servicePort: 80

4. 可以修改自己的host文件增加对应解析关系 也可以修改设置解析.
