1、首先假设你已启动了一个docker容器，并在启动时将容器的22端口映射到宿主机的10022端口
启动示例：

docker run -d --name django_api -p 8000:80 -p 10022:22 -p 5000:5000 --link mysql_host:mymysql --link redis_host:myredis  -v $PWD:/home/docker/code/app/:Z python3/django/ngnix

 启动后使用xshell远程链接宿主机的10022端口是没法链接成功的，此时咱们须要进入docker容器内部进行一些操做：

2、进行容器内部修改
彩蛋：文章最后我会讲解如何修改Dockerfile 使其在创建时就容许ssh远程登录

docker exec -it 容器名 /bin/bash

一、修改root用户密码

passwd

二、首先检查容器内部是否以安装 openssh-server与openssh-client 若没安装执行一下命令安装

apt-get install openssh-server
apt-get install openssh-client

三、修改SSH配置文件如下选项

vim /etc/ssh/sshd_config

# PermitRootLogin prohibit-password # 默认打开 禁止root用户使用密码登录，须要将其注释
RSAAuthentication yes #启用 RSA 认证
PubkeyAuthentication yes #启用公钥私钥配对认证方式
PermitRootLogin yes #容许root用户使用ssh登陆

四、启动sshd服务

/etc/init.d/ssh restart

 五、退出容器，链接测试

ssh root@127.0.0.1 -p 10022

输入密码成功进入容器内部即配置成功

 六、如若须要将修改后的容器从新保存为镜像，则可进行相应处理，本文直接使用修改后的镜像进行后续操做

3、使用Pycharm远程链接
一、打开配置界面

二、按照远程服务器信息配置信息：配置好后能够点击测试链接测试是否可以链接成功

 

点击测试链接

 

将本地的代码和服务器代码链接

 

 此时即可以远程调试代码了

 

测试上传本地代码到服务器：

 

彩蛋：修改Dockerfile 创建镜像时就容许用户经过远程链接
因为我在CMD中启动了 supervisord 此时容器启动后须要手动进入容器启动sshd

/etc/init.d/ssh start
或者将启动命令放入supervisor-app.conf文件中，使其创建容器时就启动
