Ingress-nginx安装部署

Ingress-nginx安装部署

1.部署文件下载

# 下载地址
https://github.com/kubernetes/ingress-nginx/tree/nginx-0.30.0

# configmap.yaml 存储配置信息，key/value值
# namespace.yaml 建命名空间
# mandatory.yaml 包含部署deploy相关所有资源(configmap.yaml,namespace.yaml,rbac.yaml,with-rbac.yaml)
# rbac.yaml rbac授权配置,创建Ingress需要使用的
# ServiceAccount,ClusterRole,Role,RoleBinding,ClusterRoleBinding
# with-rbac.yaml 能使用rbac授权的deploy配置，用于构建ingress-controller

2.service文件下载

# 下载地址
https://github.com/kubernetes/ingress-nginx/tree/nginx-0.30.0

3(1).修改mandatory.yaml的镜像源

# 将镜像源 quay.io 替换成 quay.azk8s.cn
sed -i 's/quay.io/quay.azk8s.cn/' mandatory.yaml

3(2).部署DaemonSet(VIP用)

# 1.将Deployment改为DaemonSet
# 2.注释掉replicas
# 3.与nodeSelector同级添加hostNetwork: true(Service的type需要改为ClusterIP)
# 4.在nodeSelector下添加标签ingress: "true"
# 5.给node打标签
kubectl label nodes <node-name> <label-key>=<label-value> 

4.部署ingress-nginx-controller

kubectl apply -f mandatory.yaml

5.部署ingress-nginx-sevice

# 可以指定nodePort: 30443
# 如果ingress DaemonSet下的spec的hostNetwork为true，则需要将Service的type改为ClusterIP
kubectl apply -f service-nodeport.yaml

6.部署ingress-nginx

vi ingress-hr-web.yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-hr-web
  namespace: default
  annotations: 
    kubernets.io/ingress.class: "nginx"
spec:
  rules:
  - host: hr-web.liuyu.com
    http:
      paths:
      - path: 
        backend:
          serviceName: hr-web-svc
          servicePort: 8999

7.修改本机与服务器的hosts

# 修改为keepalived上配置的vip
