1. 安装Docker
1.1 安装KVM
参考: https://ubuntu.com/blog/kvm-hyphervisor
1
| sudo apt -y install bridge-utils cpu-checker libvirt-clients libvirt-daemon qemu qemu-kvm
|
检查虚拟化功能
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
- 卸载旧版本
1
| sudo apt-get remove docker docker-engine docker.io containerd runc
|
- 设置软件源

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
