compose安装nginx反向代理

IDEA安装docker插件

idea安装docker插件。Dockerfile、docker-compose.yml文件大部分内容会有提示信息。方便开发人员编写配置文件。

https://plugins.jetbrains.com/plugin/7724-docker/versions

基础镜像

docker pull 1.21.0-alpine
docker pull tomcat:9.0.20-jre8-alpine

试运行镜像

# 试运行镜像并获取nginx、tomcat配置文件，进行目录持久化
docker run -itd --name nginx -p 80:80 nginx:1.21.0-alpine
docker run -itd --name tomcat -p 8080:8080 tomcat:9.0.20-jre8-alpine
docker cp nginx:/etc/nginx/ /data
docker cp tomcat:/usr/local/tomcat/webapps /data/tomcat1/webapps
docker cp tomcat:/usr/local/tomcat/webapps /data/tomcat2/webapps
echo "tomcat1" > /data/tomcat1/webapps/ROOT/index.jsp
echo "tomcat2" > /data/tomcat2/webapps/ROOT/index.jsp
ocker rm -f nginx tomcat

修改nginx配置文件

# 在nginx.conf尾行增加内容 
include vhost/*.conf;

增加反向代理配置

mkdir -p /data/nginx/vhost 
cd vhost 
vi upstream.com.conf 

upstream nginxupstream{ 
    server 10.211.55.7:8081; 
    server 10.211.55.7:8082; 
}

server{
    listen 80; 
    server_name 10.211.55.7; 
    autoindex on; 
    index index.html index.htm index.jsp; 
    location / { 
        proxy_pass http://nginxupstream; 
        add_header Access-Control-Allow-Origin *; 
    } 
}

编写docker-compose

version: '3'
services:
    test-nginx:
        restart: always
        container_name: test-nginx
        volumes:
            - /data/nginx:/etc/nginx/
        image: nginx:1.21.0-alpine
        ports:
            - 80:80
    test-tomcat1:
        restart: always
        container_name: test-tomcat1
        volumes:
            - /data/tomcat1/webapps:/usr/local/tomcat/webapps
        image: tomcat:9.0.20-jre8-alpine
        ports:
            - 8081:8080
        depends_on:
            - test-nginx
    test-tomcat1:
        restart: always
        container_name: test-tomcat2
        volumes:
            - /data/tomcat2/webapps:/usr/local/tomcat/webapps
        image: tomcat:9.0.20-jre8-alpine
        ports:
            - 8081:8080
        depends_on:
            - test-nginx

启动服务

# 不指定compose文件，默认找当前文件夹下docker-compose文件
# -d后台运行
docker-compose up -d
# 指定compose文件运行
docker-compose -f compose/docker-compose.yaml up -d
