docker asp.net core 2.0 nginx 负载均衡

1. 安装docker；

2. vs2017 创建asp.net core项目，并添加docker支持；

3. docker-compose build 创建docker镜像；

4. docker run -d -p 5001:80 --name dockerdemo.web1 dockerdemo 创建容器（多个）；

5. docker ps 查看创建的容器；

6. docker inspect 查看容器信息，ip地址；

7. docker pull nginx 下载nginx镜像

    docker run -d -p 8080:80  E:\SampleCode\DockerDemo\nginx\nginx.conf:/etc/nginx/nginx.conf nginx  启动一个新的Nginx容器并通过挂载的方式将配置文件共享到容器内部（nginx.conf）

8. 编辑本地nginx.conf

        server_name  localhost;

        #charset koi8-r;
        #access_log  /var/log/nginx/host.access.log  main;

        location / {
            proxy_pass http://demo_server;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   /usr/share/nginx/html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }
}

9. 重启nginx容器  docker restart 容器id/名称；

10. 浏览器中访问 http://localhost:8080/
