Docker Engine – Community 支持上 x86_64(或 amd64)armhf,arm64,s390x (IBM Z),和 ppc64le(IBM的Power)架构。
Docker 安装有一键安装,也有手动安装,手动安装相对来说会复杂一些。国内有一键安装的方式,今天主要讲解一键安装的方法。
卸载旧版本
Docker的旧版本被称为docker
,docker.io
或docker-engine
。如果安装了这些,请卸载它们:
$ sudo apt-get remove docker docker-engine docker.io containerd runc
如果apt-get
报告未安装这些软件包,则可以。
的内容(/var/lib/docker/
包括图像,容器,卷和网络)被保留。如果您不需要保存现有数据,并希望从全新安装开始,请参阅 此页面底部的“卸载Docker Engine”部分。
一键安装
可以使用国内 daocloud 一键安装命令:
curl -sSL https://get.daocloud.io/docker | sh
安装的过程中会在一个地方卡主,如下图:
什么原因?(新手不知道,后续知道再补充!我猜他是在下载docker安装包)
我的方法是关闭命令控制面板,重新使用命令再试一下,然后再相同的地方又会卡主,不过等一会就安装成功了。
以下是命令行:
root@ubuntu:/home/louis# curl -sSL https://get.daocloud.io/docker | sh
# Executing docker install script, commit: 3d8fe77c2c46c5b7571f94b42793905e5b3e42e4

+ sh -c echo "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable" > /etc/apt/sources.list.d/docker.list
+ sh -c apt-get update -qq >/dev/null
+ [ -n ]
+ sh -c apt-get install -y -qq --no-install-recommends docker-ce >/dev/null
+ sh -c docker version

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:
sudo usermod -aG docker your-user
Remember that you will have to log out and back in for this to take effect!
WARNING: Adding a user to the "docker" group will grant the ability to run containers which can be used to obtain root privileges on the docker host. Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface for more information.

卸载Docker
- 卸载Docker Engine,CLI和Containerd软件包:
$ sudo apt-get purge docker-ce docker-ce-cli containerd.io
- 主机上的映像,容器,卷或自定义配置文件不会自动删除。要删除所有图像,容器和卷:
$ sudo rm -rf /var/lib/docker $ sudo rm -rf /var/lib/containerd
您必须手动删除所有已编辑的配置文件。
