Ubuntu24.04安装docker(阿里镜像源)

1.刷新系统源/更新系统

sudo apt-get update && sudo apt-get upgrade -y

2.安装依赖包

sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release

3.添加阿里云Docker镜像源GPG秘钥

curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

4.添加阿里云镜像源

echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/nul

5.更新apt源

sudo apt-get update

6.安装Docker

sudo apt-get install docker-ce docker-ce-cli containerd.io

7.启动Docker服务

sudo systemctl start docker

8.设置Docker服务自启（可跳过）

sudo systemctl enable docker

9.查看Docker是否启动成功

sudo systemctl status docker

10.如果不想用root执行Docker指令，则需要将用户添加到docker的用户组中

sudo groupadd docker
sudo usermod -aG docker $USER
newgrp docker

11.设置Docker镜像（推荐做）

sudo vim /etc/docker/daemon.json
# 写入以下内容
{
    "registry-mirrors": [
        "https://docker.1panel.live",
        "https://hub.rat.dev"
    ]
}
# 然后重启docker
sudo systemctl daemon-reload
sudo systemctl restart docker

12.尝试pull镜像（这里用busybox）

docker pull busybox

13.查看结果

docker images
