查看默认配置
1
| docker --rm --entrypoint=cat nginx /etc/nginx/nginx.conf
|
--rm 表示运行完就删掉容器--entrypoint=cat 表示替换掉容器的默认命令，使用cat命令
导出默认配置到宿主机当前运行目录
1
| docker --rm --entrypoint=cat nginx /etc/nginx/nginx.conf > myconf.nginx
|
服务端真实地址是 http://localhost:8080/admin/ 我们希望隐藏掉服务器地址和/admin这个路径，使得访问地址变成 http://localhost/api，那我们就可以匹配这个路径，设置代理服务器。

| # 反向代理,处理管理端发送的请求。http://localhost/api --> http://localhost:8080/admin
location /api/ {
proxy_pass http://localhost:8080/admin/;
}
|
在本地调试的时候，如果想访问宿主机springboot运行的后端8080端口，无法在docker上使用localhost访问，查阅文档知，容器可以通过host.docker.internal 访问宿主机ip。所以我们可以写成

| # 反向代理,处理前端发送的请求到宿主机
# http://localhost/api --> http://host.docker.internal:8080/admin
location /api/ {
# proxy_pass http://localhost:8080/admin/;
proxy_pass http://host.docker.internal:8080/admin/;
}
|
例如有两台后端服务器，分别是 ip1:8080 与ip2:8080，配置如下，weight是权重配置
1

4
| upstream webservers{
server ip1:8080 weight=90;
server ip2:8088 weight=10;
}
|
设置完之后别忘了修改反向代理服务器为负载均衡upstream 指定的名称webservers

| # 反向代理,处理管理端发送的请求
location /api/ {
# proxy_pass http://localhost:8080/admin/;
proxy_pass http://webservers/admin/;
}
|
使用-v指令挂载宿主机html目录与nginx.conf文件
1
| docker run --rm -it -p 80:80 -v C:\\Users\\Administrator\\docker\\cangqiongwaimai\\nginx1.20.0\\html:/etc/nginx/html -v C:\\Users\\Administrator\\docker\\cangqiongwaimai\\nginx1.20.0\\conf\\nginx.conf:/etc/nginx/nginx.conf nginx:1.20.2
|
由于反斜杠在yml中会被识别为转义字符，所以只能用/ 替代

dockercompose 运行命令
-f docker-compose.yml 指定配置文件为docker-compose.yml，如果配置文件名称就是docker-compose.yml 可以省略up 启动服务-d 和docker run -d 命令一样，是后台运行
1
| docker compose -f docker-compose.yml up -d
|
停止服务
1
| docker compose -f docker-compose.yml down
