大家好，又见面了，我是你们的朋友全栈君。
Pycharm远程调试服务器中的代码（docker容器内部）
一、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远程连接宿主机的10022端口是无法连接成功的，此时我们需要进入docker容器内部进行一些操作：
二、进行容器内部修改
彩蛋：文章最后我会讲解如何修改Dockerfile 使其在建立时就允许ssh远程登陆
docker exec -it 容器名 /bin/bash
1、修改root用户密码
passwd
2、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
3、修改SSH配置文件以下选项
vim /etc/ssh/sshd_config # PermitRootLogin prohibit-password # 默认打开 禁止root用户使用密码登陆，需要将其注释 RSAAuthentication yes #启用 RSA 认证 PubkeyAuthentication yes #启用公钥私钥配对认证方式 PermitRootLogin yes #允许root用户使用ssh登录
4、启动sshd服务
/etc/init.d/ssh restart
5、退出容器，连接测试
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
6、如若需要将修改后的容器重新保存为镜像，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作
三、使用Pycharm远程连接
1、打开配置界面
2、按照远程服务器信息配置信息：配置好后可以点击测试连接测试是否能够连接成功
点击测试连接
将本地的代码和服务器代码连接
此时便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 建立镜像时就允许用户通过远程连接
由于我在CMD中启动了 supervisord 此时容器启动后需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，使其建立容器时就启动
