Docker 应用部署

部署 Nginx

1. 搜索并拉取 Nginx 镜像

   docker search nginx
   

   docker pull nginx:1.26.3
   

2. 创建容器，设置端口映射、目录映射

   默认 nginx.config

   user  nginx;
   worker_processes  1;
   
   error_log  /var/log/nginx/error.log warn;
   pid        /var/run/nginx.pid;
   
   events {
       worker_connections  1024;
   }
   
   http {
       include       /etc/nginx/mime.types;
       default_type  application/octet-stream;
   
       log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                       '$status $body_bytes_sent "$http_referer" '
                       '"$http_user_agent" "$http_x_forwarded_for"';
   
       access_log  /var/log/nginx/access.log  main;
   
       sendfile        on;
       #tcp_nopush     on;
   
       keepalive_timeout  65;
   
       #gzip  on;
   
       server {
           listen       80 default_server;
           listen       [::]:80 default_server;
           server_name  _;
           root         /usr/share/nginx/html;
   
           location / {
               index  index.html index.htm;
           }
   
           error_page  404              /404.html;
           location = /404.html {
           }
   
           error_page   500 502 503 504  /50x.html;
           location = /50x.html {
           }
       }
   
       # server {
       #     listen       80;
       #     server_name  example.com;
       #     root         /var/www/example.com;
       #     location / {
       #         try_files $uri $uri/ =404;
       #     }
       # }
   }
   

   docker run -id --name=docker_nginx \ 
   -p 80:80 "(1)!"
   -v $PWD/conf/nginx.conf:/etc/nginx/nginx.conf \ "(2)!"
   -v $PWD/logs/var/log/nginx \ "(3)!"
   -v $PWD/html:/usr/share/nginx/html \
   nginx "(4)!"
   

   1. 端口映射，让本机的 80 端口映射到 nginx 容器的 80 端口
   2. 数据卷，让本地当前目录($PWD)下的 /conf/nginx.conf Nginx 配置文件映挂载到容器中，其余的数据卷是同样的道理，「配置文件要提前准备好」
