ubuntu 安装 docker

打开网站：

Ubuntu | Docker Docs

卸载冲突包

for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt-get remove $pkg; done

运行以下命令

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] 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

最后更新时可能报错，更换docker源进行解决

更换阿里源

sudo sed -i 's|https://download.docker.com|https://mirrors.aliyun.com/docker-ce|g' /etc/apt/sources.list.d/docker.list

再次运行

sudo apt-get update

安装docker

安装最新版本

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

安装特定版本

先查询版本

# List the available versions:
apt-cache madison docker-ce | awk '{ print $3 }'

5:27.4.0-1~ubuntu.24.04~noble
5:27.3.1-1~ubuntu.24.04~noble
...

选择想要安装的版本进行安装（例如 5:27.4.0-1~ubuntu.24.04~noble）

VERSION_STRING=5:27.4.0-1~ubuntu.24.04~noble
sudo apt-get install docker-ce=$VERSION_STRING docker-ce-cli=$VERSION_STRING containerd.io docker-buildx-plugin docker-compose-plugin

验证

sudo docker run hello-world

在 etc/docker/daemon.json 文件中添加如下源，如果没有这个文件，自己创建

"registry-mirrors": [
    "https://registry.docker-cn.com",
    "http://hub-mirror.c.163.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://cr.console.aliyun.com",
    "https://mirror.ccs.tencentyun.com",
    "https://do.nark.eu.org",
    "https://dc.j8.work",
    "https://docker.m.daocloud.io",
    "https://dockerproxy.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://docker.nju.edu.cn"
  ]
}
