docker run \ 
‐‐name app1 \
‐‐network my‐bridge \ 
‐p 8080:8080 \ 
‐d itlaoqi/bsbdj:1.0

docker run \
‐‐name app2 \
‐‐network my‐bridge \ 
‐p 8081:8080 \ 
‐d itlaoqi/bsbdj:1.0

docker run \

整体解决方案，最佳实践

ngnix+三个后端服务一键式部署:

```shell
docker network create ‐d bridge my‐bridge

docker run
‐p 3306:3306 \
‐‐network my‐bridge \
‐‐name db \
‐v /usr/local/bsbdj/sql:/docker‐entrypoint‐initdb.d \
‐v /usr/local/bsbdj/data:/var/lib/mysql
‐e MYSQL_ROOT_PASSWORD=root
‐d mysql:5.7

这里是构建镜像

cd /usr/local/bsbdj
docker build ‐t itlaoqi/bsbdj:1.0 .

docker run
‐‐name app1
‐‐network my‐bridge \
‐p 8080:8080
‐d itlaoqi/bsbdj:1.0

docker run ‐‐name app2 \
‐‐network my‐bridge
‐p 8081:8080 \
‐d itlaoqi/bsbdj:1.0

docker run
‐‐name app3
‐‐network my‐bridge
‐p 8082:8080
‐d itlaoqi/bsbdj:1.0

docker run ‐‐name nginx \
‐v /usr/local/bsbdj/nginx/nginx.conf:/etc/nginx/nginx.conf \
‐‐network my‐bridge \
‐p 80:80 \
‐d nginx
