Docker安装
设置存储库
更新apt软件包索引并安装软件包以允许apt通过HTTPS使用存储库:
sudo apt-get update && sudo apt upgrade
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
gnupg \
lsb-release
添加Docker的官方GPG密钥:
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
使用以下命令来设置稳定的存储库。
echo \
"deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
安装DOCKER引擎
更新apt程序包索引,并安装最新版本的Docker Engine和容器化的容器,或转到下一步以安装特定版本:
sudo apt-get update
sudo apt-get install docker-ce docker-ce-cli containerd.io
配置
添加用户到Docker组
sudo usermod -aG docker yjw #yjw是我的用户名
cat /etc/group | grep docker #查看
查看Docker版本
docker --version
docker system info
添加国内源
sudo vim /etc/docker/daemon.json
添加如下
{
"registry-mirrors": ["https://alzgoonw.mirror.aliyuncs.com"]
}
{
"registry-mirrors" : [
"http://docker.mirrors.ustc.edu.cn",
"http://registry.docker-cn.com",
"https://mirror.ccs.tencentyun.com",
"http://hub-mirror.c.163.com"
],
"insecure-registries" : [
"registry.docker-cn.com",
"docker.mirrors.ustc.edu.cn"
],
"debug" : true,
"experimental" : true
}

重启服务
systemctl restart docker
sudo systemctl status docker
测试
sudo docker run hello-world
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 bash

Docker 卸载
卸载docker:
sudo apt-get purge docker-ce docker-ce-cli containerd.io
sudo apt-get autoremove docker docker-ce docker-engine docker.io containerd runc
删除docker其他没有没有卸载
dpkg -l | grep docker
sudo apt-get autoremove docker-ce-*
删除docker的相关配置&目录
sudo rm -rf /etc/systemd/system/docker.service.d
sudo rm -rf /var/lib/docker
sudo rm -rf /var/lib/containerd
删除所有带 rc 标记的dpkg包
dpkg -l | grep ^rc | cut -d' ' -f3 | sudo xargs dpkg --purge
