## Source File
- [[raw/Home Office/如何在Ubuntu Server安装 docker & docker compose.md]]

## Summary
- 核心主题：Ubuntu Server安装Docker Engine和Docker Compose V2
- 问题域：官方仓库安装确保版本最新
- 方法/机制：添加Docker GPG密钥 → 添加apt源 → apt install
- 结论/价值：完整的Ubuntu Docker官方安装流程

## Key Claims
- 卸载旧版：for pkg in docker.io docker-engine docker-ce docker.io docker-compose docker-compose-v2; do sudo apt-get remove $pkg; done
- 添加GPG密钥：sudo install -m 0755 -d /etc/apt/keyrings && sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
- 添加apt源：echo "deb [arch=$(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
- 安装：sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
- 非root用户运行：sudo usermod -aG docker $USER

## Key Concepts
- [[DockerEngine]]：Docker容器运行时
- [[DockerComposeV2]]：docker compose命令（V2版本）
- [[apt仓库管理]]：通过GPG密钥和apt源安装软件

## Key Entities
- [[Docker]]：容器化平台
- [[Ubuntu]]：安装宿主
