前言
vscode连接docker方便开发，此处主要用在hexo的博客编写，很方便~
安心码文了~

构建命令，在Dockerfile的同目录运行：
1
| docker build -f Dockerfile -t blog .
|
1.2 创建容器
1
| docker run -it --name=xinwen -p 4000:4000 -p 8022:22 -v /home/xinwen/xinwenblog:/xinwen blog
|
2，宿主机和docker中关于ssh的配置
2.1 docker允许远程登录
在docker中修改sshd服务的配置文件，在/etc/ssh/sshd_config位置，将下面的配置项去掉注释即可。
1
2
3
| PermitRootLogin yes
PubkeyAuthentication yes
PasswordAuthentication yes
|
保存后重启sshd服务，也就是：
2.2 宿主机查看docker的ip
在宿主机上运行，xinwen是docker别名。
2.3 登录宿主机进行连接验证
密码登录或者ssh免密登录方式都可以，二者择一即可。
复制宿主机的公钥到docker中
1
| ssh-copy-id -i /home/xinwen/.ssh/id_rsa.pub root@172.17.0.2
|
root是docker的用户，172.17.0.2是docker的ip，/home/xinwen/.ssh/id_rsa.pub是宿主机的公钥。
- 验证登录
输出下面信息就成功了

3，VSCODE插件
主要是两个插件Docker和Remote-Containers
点击左下角”><“标志，在顶部的输入下拉框选择Attach to Running Container...就能打开docker的home目录。
