win10修改docker镜像的存储位置 将win10更新至最新，目前最新版本是20H2，在安装docker desktop(基于wsl2)后，直接下载镜像默认是安装在C盘的，如果C盘空间不足，可按如下方式转移至其它盘docker启动后会自动运行下面两个镜像，docker-desktop是存放程序的，docker-desktop-data是存放镜像的，这两个wsl子系统都是默认放在系统盘的。PS C:\Users\Administrator> wsl -l -v --all NAME STATE VERSION * docker-desktop Running 2 docker-desktop-data Running 21、停止wslwsl --shutdown2、导出前面docker的两个镜像wsl --export docker-desktop-data D:\docker\docker-desktop-data.tar wsl --export docker-desktop D:\docker\docker-desktop.tar3、取消注册wsl --unregister docker-desktop-data wsl --unregister docker-desktop4、将导出的镜像导入到你要转移的目标位置// 用于存储镜像目录 D:\docker\image wsl --import docker-desktop-data D:\docker\image D:\docker\docker-desktop-data.tar // 运行docker主程序目录 D:\docker\bin wsl --import docker-desktop D:\docker\bin D:\docker\docker-desktop.tar5、确认是否转移成功PS C:\Users\Administrator> wsl -l -v --all NAME STATE VERSION * docker-desktop Stopped 2 docker-desktop-data Stopped 26、重新启动docker desktop

ssh服务未启动，22端口启用 这里使用的容器是centos7环境，基本是个比较纯净的环境，几乎什么都没装根据自己需求，先安装一些基本的（容器，默认是root用户）yum install -y net-tools接着安装openssl，openssh-serveryum install -y openssl openssh-server然后启动ssh/usr/sbin/sshd -D这里会报错[root@68e7598797d7 /]# /usr/sbin/sshd -D Could not load host key: /etc/ssh/ssh_host_rsa_key Could not load host key: /etc/ssh/ssh_host_ecdsa_key Could not load host key: /etc/ssh/ssh_host_ed25519_key需要进行下面的设置[root@68e7598797d7 /]# ssh-keygen -q -t rsa -b 2048 -f /etc/ssh/ssh_host_rsa_key -N '' [root@68e7598797d7 /]# ssh-keygen -q -t ecdsa -f /etc/ssh/ssh_host_ecdsa_key -N '' [root@68e7598797d7 /]# ssh-keygen -t dsa -f /etc/ssh/ssh_host_ed25519_key -N ''接着修改sshd_config文件配置信息，路径为 /etc/ssh/sshd_config1.将 Port 22 前面的注释去掉（开启22号端口）2.将 PermitRootLogin 的 no 改为 yes （这里是设置是否允许root用户登录，可根据自己需求决定是否开启）重新启动ssh[root@68e7598797d7 /]# /usr/sbin/sshd -D &注意，如果设置都没问题的话，命令结尾加个‘&’，自动后台运行，启动成功会返回进程号[root@68e7598797d7 /]# /usr/sbin/sshd -D & [1] 16给root添加密码添加过的可跳过此步骤[root@68e7598797d7 /]# yum install passwd [root@68e7598797d7 /]# passwd
