『中级篇』docker之运行nginx跳转到本地的jar并配置https（番外篇）（80）

真实的环境，一个1核2g内存，安装了mysql容器，java容器，nginx容器。具体安装docker我就不说了，没啥讲的重复很多遍的。mysql 也之前讲过。

nginx的安装

• 新建立nginx的目录

nginx

• 防止出现下面的错误

docker: Error response from daemon: oci runtime error: container_linux.go:262: starting container process caused "process_linux.go:339: container init caused "rootfs_linux.go:57: mounting \"/root/conf/nginx/nginx.conf\" to rootfs

: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type.

• 命令建立

确定文件夹存在

touch conf/nginx.conf
echo 1 > conf/nginx.conf

创建容器

docker run -d -p 80:80 \
--name five-nginx \
-p 443:443 \
-v /home/user/nginx/cert:/etc/nginx/cert \
-v /home/user/nginx/config/nginx.conf:/etc/nginx/nginx.conf \
-v /home/user/nginx/html:/usr/share/nginx/html \
-v /home/user/nginx/log:/var/log/nginx \
hub.c.163.com/library/nginx

• 配置nginx文件

#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;
    server {
        listen       80;
        server_name  www.abc.xyz;
        rewrite ^ https://$http_host$request_uri? permanent;
    }
    server {
        listen 443;
        server_name www.abc.xyz;
        ssl on;
        ssl_certificate /etc/nginx/cert/www.idig8.xyz.crt;
        ssl_certificate_key /etc/nginx/cert/www.idig8.xyz.key;
        ssl_session_timeout 5m;
        location / {
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-NginX-Proxy true;
            proxy_pass http://172.17.0.3:8888/;
            proxy_redirect off;
        }
    }
}

• java项目启动使用的是8888端口

nginx的配置 proxy_pass 不能使用127.0.0.1:8888
必须使用java容器内部的ip地址http://172.17.0.3:8888/; 可以通过docker inspect 来进行查看。

• https的配置

把cert阿里云中下载的crt，key放入指定的目录cert中。

PS：基本的nginx容器配置秘钥和key，跳转返回的时候，访问java容器的IP。
