• Set up
  
  Docker’s package repository
  
  .
  

一：Set up the repository

1. Update the
   
apt

   package index and install packages to allow
   
apt

   to use a repository over HTTPS:
   

$sudo apt-get update
$sudo apt-get install \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

2.Add Docker’s official GPG key:

$sudo mkdir -m 0755 -p /etc/apt/keyrings
$curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

3.Use the following command to set up the repository:

 $echo \
  "deb [arch=$(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

二：Install Docker Engine

1.Update the

apt

package index:

$ sudo apt-get update

2.Install Docker Engine, containerd, and Docker Compose.

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

3.Verify that the Docker Engine installation is successful by running the

hello-world

image:

$ sudo docker run hello-world

• Download latest
  
  DEB package
  
  .
  

• Install the package with apt as follows:
  

  $ sudo apt-get update
  $ sudo apt-get install ./docker-desktop-<version>-<arch>.deb

  遇到问题：在”Install the package with apt as follows:”步骤时，先到下载目录，在执行sudo install ；并且<version>-<arch>要和安装包对应起来！
