Kubernetes(k8s) 配置 Nginx

k8s 安装教程请参考：http://www.javashuo.com/article/p-prmsiugp-mo.htmlhtml

Nginx安装配置参考： https://www.cnblogs.com/puroc/p/5764330.htmlnode

1、环境配置：nginx

master：192.168.0.38web

node1: 192.168.0.39docker

node2: 192.168.0.40api

安装完后用 kubectl get node 查看一下bash

2、建立configMapapp

kubectl create configmap confnginx --from-file nginx.conftcp

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                        '$status $body_bytes_sent "$http_referer" '
                        '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    #include /etc/nginx/conf.d/*.conf;

server {
       listen                    80;
       server_name               localhost;
       root                      /home/wwwroot/test;
       index                     index.html;
}
}

在两个Node上新建咱们的web访问目录： spa

3、建立nginx-rc.yaml

Replication Controller简称RC，它可以保证Pod持续运行，而且在任什么时候候都有指定数量的Pod副本，在此基础上提供一些高级特性，好比滚动升级和弹性伸缩。

apiVersion: v1 kind: ReplicationController metadata: name: nginx-controller spec: replicas: 2 selector: name: nginx template: metadata: labels: name: nginx spec: containers: - name: nginx image: docker.io/nginx:alpine ports: - containerPort: 80 volumeMounts: - mountPath: /etc/nginx/nginx.conf name: nginx-config subPath: nginx.conf - mountPath: /home/wwwroot/test name: nginx-data volumes: - name: nginx-config configMap: name: confnginx - name: nginx-data hostPath: path: /home/wwwroot/hello

kubectl create -f nginx-rc.yaml

4、建立nginx-svc.yaml

apiVersion: v1 kind: Service metadata: name: nginx-service-nodeport spec: ports: - port: 8000 targetPort: 80 protocol: TCP nodePort: 30080 #外网访问端口 type: NodePort #这个是端口类型 selector: name: nginx

kubectl create -f nginx-service.yaml

5、验证
