docker 安装
Docker是一个开源的应用容器引擎，让开发者可以打包他们的应用以及依赖包到一个可移植的容器中，然后发布到任何流行的Linux机器上，也可以实现虚拟化。容器是完全使用沙箱机制，相互之间不会有任何接口。
安装 Docker
Ubuntu 安装 Docker
在新主机上首次安装 Docker Engine 之前，需要设置 Docker 存储库。之后，您可以从存储库安装和更新 Docker。
- 设置 Docker 的apt存储库。
# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
# Add the repository to Apt sources:
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update- 安装 Docker 软件包
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin- 查看版本
docker -v
Docker version 24.0.7, build afdd53b安装 Docker Desktop
下载后安装就行了。

Docker Desktop时报错：The following packages have unmet dependencies: docker-desktop : Depends: docker-ce-cli but it is not installable则是因为没有设置 Docker 存储库和安装 Docker Engine。需要按顺序。
$ sudo apt-get install ./docker-desktop-4.26.1-amd64.deb
