dockernginx部署多个项目的示例方法

FROM nginx:1.13.6-alpine
LABEL maintainer="lilywang "

ARG TZ="Asia/Shanghai"

ENV TZ ${TZ}

RUN apk upgrade --update \
 && apk add bash tzdata \
 && ln -sf /usr/share/zoneinfo/${TZ} /etc/localtime \
 && echo ${TZ} > /etc/timezone \
 && rm -rf /var/cache/apk/*

COPY dist /usr/share/nginx/html 

CMD ["nginx", "-g", "daemon off;"]

docker run -itd --name web -p 80:80 -v /root/nginx/nginx.conf:/etc/nginx/nginx.conf lilywang711/web
// -i 交互模式运行容器, -t 为容器分配一个伪终端，-d 后台运行容器，可直接连写 -itd
// --name 是给该容器起个叫web的名字，方便辨识
// -p 是绑定端口 本机端口80:容器端口80
// -v 声明volume，意思是将容器中的/etc/nginx/nginx.conf 挂载到 宿主机里的/root/nginx/nginx.conf，以后配置nginx只需要修改/root/nginx/nginx.conf就行了
