安装Docker前卸载之前的，避免出现错误
for pkg in docker.io docker-doc docker-compose podman-docker containerd runc; do sudo apt-get remove $pkg; done
1、设置 Docker 的 Apt 存储库。
# Add Docker’s official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
Add the repository to Apt sources:
echo
“deb [arch=”$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] Index of linux/debian/
“$(. /etc/os-release && echo “$VERSION_CODENAME”)” stable" |
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
2、安装 Docker 软件包。
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
3、 通过运行映像验证安装是否成功：hello-world
sudo docker run hello-world
正常是可以成功了，但我的报错。
