helm安装ingress

​

helm安装ingress

​一、安装Helm

?

1 2 3 4 5 6 7 8

# wget https://get.helm.sh/helm-v3.3.4-linux-amd64.tar.gz ​ # tart -zxvf helm-v3.3.4-linux-amd64.tar.gz ​ # mv linux-amd64/helm /usr/local/bin/helm ​ # helm version version.BuildInfo{Version:"v3.3.4", GitCommit:"a61ce5633af99708171414353ed49547cf05013d", GitTreeState:"clean", GoVersion:"go1.14.9"}

　　 

二、下载ingress

?

1 2 3 4 5 6

# mkdir ingress && cd ingress # 新建仓库 # helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx ​ # helm pull ingress ingress-nginx/ingress-nginx # tar -xf ingress-nginx-3.7.1.tgz && cd ingress-nginx

　　

三、安装ingress

1. 修改values.yaml

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

# 修改controller镜像地址 repository: registry.cn-beijing.aliyuncs.com/dotbalo/controller ​ # dnsPolicy dnsPolicy: ClusterFirstWithHostNet ​ # 使用hostNetwork,即使用宿主机上的端口80 443 hostNetwork: true ​ # 使用DaemonSet,将ingress部署在指定节点上 kind: DaemonSet ​ # 节点选择，将需要部署的节点打上ingress=true的label   nodeSelector:     kubernetes.io/os: linux     ingress: "true"       # 修改type,改为ClusterIP。如果在云环境，有loadbanace可以使用loadbanace type: ClusterIP ​ # 修改kube-webhook-certgen镜像地址 registry.cn-beijing.aliyuncs.com/dotbalo/kube-webhook-certgen

　　

2. 安装ingress

?

1 2 3 4 5 6 7 8 9 10 11 12 13

# 选择节点打label # kubectl label node node01 ingress=true ​ # 创建一个ingress的namespace # kubectl create ns ingress-nginx ​ # 创建ingress # helm install ingress-nginx -n ingress-nginx ​ # kubectl get pods -n ingress-nginx -owide NAME                             READY   STATUS    RESTARTS   AGE   IP               NODE     NOMINATED NODE   READINESS GATES ingress-nginx-controller-mrb2t   1/1     Running   0          15h   192.168.10.243   node01   <none>           <none>

　　

四、使用ingress

1. Ingress配置文件

   ?

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

   ingress-example.yaml   apiVersion: networking.k8s.io/v1beta1 kind: Ingress metadata:   name: example-ingress   annotations:     kubernetes.io/ingressClass: "nginx" spec:   rules:   - host: foo.bar.com     http:       paths:       - path: /         backend:           serviceName: nginx-svc           servicePort: 80

   　　

   kubernetes.io/ingressClass: "nginx"：使用ingressClass: "nginx"，告诉ingress实现的配置

   rules： 一个rules可以有多个host

   host : 访问ingress的域名

   path : 类似于nginx的location配置，同一个host可以配置多个path

   backend：描述Service和ServicePort的组合。对ingress匹配主机和路径的HTTP与HTTPS请求将被转发到后端Pod

    

2. 创建一个nginx的Deployment

   ?

   1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50

   apiVersion: v1 kind: Service metadata:   name: nginx-svc   labels:     app: nginx-svc spec:   selector:     app: nginx   ports:   - name: http     protocol: TCP     port: 80     targetPort: 80 --- apiVersion: apps/v1 kind: Deployment metadata:   annotations:     deployment.kubernetes.io/revision: "1"   labels:     app: nginx   name: nginx   namespace: default spec:   progressDeadlineSeconds: 600   replicas: 2 #副本数   revisionHistoryLimit: 10 # 历史记录保留的个数   selector:     matchLabels:       app: nginx   strategy:     rollingUpdate:       maxSurge: 25%       maxUnavailable: 25%     type: RollingUpdate   template:     metadata:       labels:         app: nginx     spec:       containers:       - image: nginx:1.15.2         imagePullPolicy: IfNotPresent         name: nginx         terminationMessagePath: /dev/termination-log         terminationMessagePolicy: File       restartPolicy: Always       terminationGracePeriodSeconds: 30 ​

    

3. 创建

   ?

   1 2 3

   # kubectl create -f ingress-example.yaml Warning: networking.k8s.io/v1beta1 Ingress is deprecated in v1.19+, unavailable in v1.22+; use networking.k8s.io/v1 Ingress ingress.networking.k8s.io/example-ingress created

   　　

   查看ingress

   ?

   1 2 3 4

   # kubectl get ingress Warning: extensions/v1beta1 Ingress is deprecated in v1.14+, unavailable in v1.22+; use networking.k8s.io/v1 Ingress NAME              CLASS    HOSTS         ADDRESS         PORTS   AGE example-ingress   <none>   foo.bar.com   10.101.32.165   80      107s

   　　 

4. 修改本机hosts文件，访问far.bar.com
