1确定 CPU。可以看到我们的是 X86_64是支持的如果是 arm 一般会显示aarch64

Status: Downloaded newer image for hello-world:latest Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the hello-world image from the
Docker Hub.(amd64)
3. The Docker daemon created a new container from that image
which runs the executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client,
which sent it to your terminal.To try something more ambitious, you can run an Ubuntu container
with: $ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID: https://hub.docker.com/For more examples and ideas, visit: https://docs.docker.com/get-started/3. 常见报错
1报错截图 2查看日志
#journalctl 是操作系统日志查看命令
#-e 表示从末尾看
#-u 表示看哪个系统组件的我们的组件是 docker
journalctl -eu docker3查看报错 4执行如下命令修复
systemctl daemon-reload
systemctl start docker4. Docker的镜像源修改
1对于使用 systemd 的系统Ubuntu 16.04、 Debian 8、 CentOS 7 在配置文件/etc/docker/daemon.json 中加入
{registry-mirrors: [https://docker.mirrors.ustc.edu.cn/]
}2重新启动 dockerd
sudo systemctl restart docker3参考链接https://mirrors.ustc.edu.cn/help/dockerhub.html。
5. Docker目录修改
1Docker 默认的安装目录为/var/lib/docker这里面会存放很多很多镜像所以我们在安装的时候需要考虑这个目录的空间有三种解决方案。
将/var/lib/docker 挂载到一个大的磁盘这种一般我们能控制挂载目录像腾讯云这种云厂商在安装 K8s 的节点的时候提供了挂载选项可以直接挂载这个目录过去。安装之前挂载一个大的磁盘然后创建一个软链接到/var/lib/docker这样就自动安装到我们空间比较大的磁盘了。安装了 docker然后发现忘了配置这个目录我们需要修改 docker 的配置文件。
#假定我们磁盘的大的目录为 /data
mkdir -p /data/var/lib/docker
# 编辑配置文件
vi /etc/docker/daemon.json
# 输入下面的 json
{data-root: /data/var/lib/docker
}
# 加载配置
sudo systemctl daemon-reload
# 重启 docker
sudo systemctl restart docker
#查看 docker 状态
sudo systemctl status docker2修改前在/var/lib/docker目录下 3修改后在/data/var/lib/docker目录下 6. 在CentOS系统下安装docker
