使用Nginx访问容器

我有一台 Centos 7 服务器。在这个服务器中我有 Nginx。

在此服务器中，我有一个包含我的应用程序的 Docker。

应用程序.yml：

version: '2'
services:
    myBrand-app:
        image: myBrand
        environment:
            - _JAVA_OPTIONS=-Xmx512m -Xms256m
            - SPRING_PROFILES_ACTIVE=prod,swagger
            - SPRING_DATASOURCE_URL=jdbc:postgresql://myBrand-postgresql:5432/myBrand
            - SLEEP=10 # gives time for the database to boot before the application
        ports:
            - 8080:8080
    myBrand-postgresql:
        extends:
            file: postgresql.yml
            service: myBrand-postgresql

是否可以通过我的服务器的IP通过Nginx代理访问Docker？

我想使用 Nginx 作为容器的反向代理。

答案1

以下是如何配置 nginx 将流量从互联网直接路由到您自己的服务器运行的本地主机端口。

当你安装 nginx 时，它通常会在该位置安装其默认配置文件

cat /etc/nginx/nginx.conf

在上述文件的底部附近，您应该会看到类似的内容

    include /etc/nginx/sites-enabled/default;
}

如果不只是创建上面的默认文件，如下所示

cat /etc/nginx/sites-enabled/default;

其中可以包含

server { 

    listen  80 ;

    server_name   example.com, www.example.com;

    rewrite ^/(.*) https://example.com/$1 permanent; # mysettings
}

# ..................  enduser .................. #

server {  #  redirect www to normal domain

    listen       443  ssl ;

    server_name www.example.com;

    include /etc/nginx/mysettings/include/ssl;

    return 301 https://example.com$request_uri;
}

server {

    listen  443 ssl ;

    include /etc/nginx/mysettings/include/ssl;

    server_name  example.com;

    include /etc/nginx/snippets/nginx_common_location_443;

    location / {

        # route to enduser 

        proxy_pass http://127.0.0.1:3000/;
    }


    include /etc/nginx/mysettings/include/custom_server_include;

}

在上面你看到这部分：

    location / {

        # route to enduser 

        proxy_pass http://127.0.0.1:3000/;
    }

它定义了一条路由，将来自外部互联网的流量引导到我的服务器的指定主机和端口，在上面的示例中，该主​​机和端口位于 127.0.0.1:3000 ...在您的情况下，将我的 3000 替换为您的端口 8080 ...所以现在当浏览器转到

https://example.com

该流量被路由到我的主机端口，该端口运行于

http://127.0.0.1:3000/

为了完整起见，我现在向您展示上面配置文件中提到的一些帮助程序设置文件

cat /etc/nginx/myconfig/include/ssl;

看起来像

#
# Based on https://mozilla.github.io/server-side-tls/ssl-config-generator/?server=nginx-1.4.6&openssl=1.0.1f&hsts=yes&profile=modern
ssl_certificate     /mydir/nginx/sslcerts/example.com/fullchain.pem;
ssl_certificate_key /mydir/nginx/sslcerts/example.com/privkey.pem;
ssl_session_timeout 5m;
ssl_session_cache shared:SSL:5m;

# Diffie-Hellman parameter for DHE ciphersuites, recommended 2048 bits
ssl_dhparam /etc/ssl/certs/dhparam.pem;

ssl_prefer_server_ciphers on;
ssl_protocols TLSv1.2;
ssl_ciphers 'ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256';

和另一个配置文件在这里

cat /etc/nginx/snippets/nginx_common_location_443;

其中包含

# the following is required for WebSockets
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';

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;

如果您有多个要定义的路线，您可以将它们放入一个文件中

cat /etc/nginx/myconfig/include/custom_server_include;

看起来类似于

if ( $request_method !~ ^(GET|POST|PUT|PATCH|DELETE|OPTIONS)$ ) {
    # now send to error
    return 404;
}

location ~* \.(php)$ {
    # matches any request ending in php
    return 403;
}

location /apataki {
    proxy_pass http://localhost:28778/;
}

location /hooks/ {

    # this is my webhook server
    proxy_pass http://localhost:9000/hooks/;
}

# .......

error_page 404 /error_404.html;
location = /error_404.html {
  root  /cryptdata/var/deploy;
}

error_page 502 /error_502.html;
location = /error_502.html {
  root  /cryptdata/var/deploy;
}
