2025-04-01 在 ubuntu-24.04.1 上安装 docker

参考自 https://www.sysgeek.cn/install-docker-ubuntu/

安装前置

sudo apt update
sudo apt install apt-transport-https curl

添加gpg密钥

这一步遇到问题，可能失败，失败后会在 /etc/apt/keyrings/docker.gpg 写一个空文件，需要删除后重试

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

添加仓库

虽然格式和apt自带的不一致，但是能用

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

更新软件包列表

sudo apt update

安装

这一步下载很慢，选择给apt设置代理（http_proxy环境变量居然无效） 创建文件 /etc/apt/apt.conf.d/proxy.conf 并写入

Acquire::http::Proxy "http://192.168.1.1:7890/";
Acquire::https::Proxy "http://192.168.1.1:7890/";

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

检查docker状态

sudo systemctl is-active docker

hello world

下不动哈哈哈
在 https://cloud.tencent.com/developer/article/2485043 找到了可用的两个镜像源

编辑文件 /etc/docker/daemon.json

{
  "registry-mirrors": [
    "https://docker.xuanyuan.me",
    "https://docker.1ms.run"
  ]
}

配置完成后

sudo systemctl daemon-reload
sudo systemctl restart docker
