1. 安装Docker

1.1 安装KVM

参考: https://ubuntu.com/blog/kvm-hyphervisor

sudo apt -y install bridge-utils cpu-checker libvirt-clients libvirt-daemon qemu qemu-kvm

检查虚拟化功能

kvm-ok

1.2 安装Docker

参考资料: https://docs.docker.com/engine/install/ubuntu/

我对Docker Desktop并不感兴趣, 因此选择安装无图形界面的Docker Engine

1. 卸载旧版本

sudo apt-get remove docker docker-engine docker.io containerd runc

2. 设置软件源

sudo apt update
sudo apt install ca-certificates curl gnupg lsb-release
sudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

3. 安装Docker Engine

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

4. 配置权限

sudo groupadd docker 
sudo groupadd libvirt
sudo groupadd kvm
sudo adduser $USER docker
sudo adduser $USER libvirt
sudo adduser $USER kvm
newgrp kvm
newgrp docker
newgrp libvirt

newgrp用于重新以对应群组身份登陆

2. Docker 的常用命令

构建镜像

docker build -f <dockerfile> -t <image_name:tag> .
