window11 下使用docker + vscode 搭建cpp开发环境

原本使用 vscode + vmware + ubuntu 的组合进行linux cpp的学习与开发。无奈在研究其他东西的时候需要一个docker环境，把docker安装到window环境后，出现了两个大问题：

1.idea 和 android studio 用不了了。(端口冲突问题)

2.vmware虚拟机也用不了。（与hyper-v冲突）

把第一个问题解决后，发现有了docker之后就没必要单开一个虚拟机作为cpp开发环境，何不使用更加轻量的docker来替代呢。于是开始一顿踩坑之旅。。

docker环境配置

docker安装步骤省略

背景：

在已有容器添加端口映射，为什么在已经存在的容器上修改呢，而不是将这个容器提交为镜像，然后再新的镜像基础上创建容器的时候配置参数呢。其实按照这种方式尝试解决了一下，无奈生成的镜像跑不起来新的容器。赶紧换思路解决，后期docker把玩熟了之后再回头试试这种方式。

一.修改容器配置文件

1.查看容器列表，找出要修改的容器id

 2.查看容器信息

 根据容器id信息搜索配置文件。

2.修改config.v2.json

添加容器端口配置，导出22端口

"ExposedPorts":{
            "22/tcp":{

            }
        }

3.修改hostconfig.json

添加端口映射

"22/tcp":[
            {
                "HostIp":"",
                "HostPort":"222"
            }
        ]

 配置解释： ssh 映射到主机上的 ip:port 为 127.0.0.1:222

4.重启docker,再次通过docker inspect [containerid] 查看容器信息，验证是否配置成功。

二.安装ssh服务

进入docker环境

docker exec -it 2635168136d8 /bin/bash

首先切换到root账户，如果没有的root的话添加下root账户的密码

passwd

安装ssh服务

sudo apt-get install openssh-server

修改配置

vim /etc/ssh/sshd_config

添加如下内容：

PubkeyAuthentication yes
PermitRootLogin yes

启动ssh服务

service ssh start

生成sshkey 信息

ssh-keygen -t rsa      一路回车
