docker-compse部署实践-nginx

环境

• linux centos 7.6
• Docker version 24.0.5, build ced0996
• docker-compose version v2.20.2

需求

使用 Dockerfile 构建 nginx 镜像，访问静态资源

hello nginx roadmap !!!

api_proxy.conf

nginx 配置文件
scripts/nginx/api_proxy.conf

server {
  listen 80; #监听容器内的端口
  server_name cert-view-web;
  client_max_body_size 10m;
  # 配置前端静态文件目录
  location / {
    index index.html index.htm;
    root /usr/share/nginx/html;
    try_files $uri $uri/ /index.html;
  }
  # 配置后台go服务api接口服务 代理到8081端口

}

Dockerfile

FROM nginx:1.16.1
MAINTAINER wanghaima
# 复制配置文件
COPY scripts/nginx/api_proxy.conf /etc/nginx/conf.d/api_proxy.conf
# 复制宿主机当前路径上的roadmap目录，到容器/usr/share/nginx/目录中，并改名为html
COPY roadmap /usr/share/nginx/html

EXPOSE 88

# 防止主程序退出后，nginx容器也就退出了
CMD ["nginx", "-g", "daemon off;"]
