2、nginx.conf

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" '

    keepalive_timeout  65;

    #gzip  on;

    # 引入自定义配置
    include /etc/nginx/conf.d/*.conf;
}

3、default.conf

server {
    listen       80;
    server_name  localhost;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

4、制作镜像

docker build -t java_nginx:latest .

5、运行测试

运行测试
docker run -itd -p 80:80 --name java_nginx java_nginx:latest
