1、首先假設你已啓動了一個docker容器，並在啓動時將容器的22端口映射到宿主機的10022端口
啓動示例：

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

 啓動後使用xshell遠程鏈接宿主機的10022端口是沒法鏈接成功的，此時咱們須要進入docker容器內部進行一些操做：

2、進行容器內部修改
彩蛋：文章最後我會講解如何修改Dockerfile 使其在創建時就容許ssh遠程登錄

docker exec -it 容器名 /bin/bash

一、修改root用戶密碼

passwd

二、首先檢查容器內部是否以安裝 openssh-server與openssh-client 若沒安裝執行一下命令安裝

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

三、修改SSH配置文件如下選項

vim /etc/ssh/sshd_config

# PermitRootLogin prohibit-password # 默認打開 禁止root用戶使用密碼登錄，須要將其註釋
RSAAuthentication yes #啓用 RSA 認證
PubkeyAuthentication yes #啓用公鑰私鑰配對認證方式
PermitRootLogin yes #容許root用戶使用ssh登陸

四、啓動sshd服務

/etc/init.d/ssh restart

 五、退出容器，鏈接測試

ssh root@127.0.0.1 -p 10022

輸入密碼成功進入容器內部即配置成功

 六、如若須要將修改後的容器從新保存爲鏡像，則可進行相應處理，本文直接使用修改後的鏡像進行後續操做

3、使用Pycharm遠程鏈接
一、打開配置界面

二、按照遠程服務器信息配置信息：配置好後能夠點擊測試鏈接測試是否可以鏈接成功

 

點擊測試鏈接

 

將本地的代碼和服務器代碼鏈接

 

 此時即可以遠程調試代碼了

 

測試上傳本地代碼到服務器：

 

彩蛋：修改Dockerfile 創建鏡像時就容許用戶經過遠程鏈接
因爲我在CMD中啓動了 supervisord 此時容器啓動後須要手動進入容器啓動sshd

/etc/init.d/ssh start
或者將啓動命令放入supervisor-app.conf文件中，使其創建容器時就啓動
