ubuntu安装配置docker

安装和开机自启

# 1. 更新包列表
sudo apt update

# 2. 安装必要的依赖包
sudo apt install -y apt-transport-https ca-certificates curl software-properties-common gnupg lsb-release

# 3. 添加 Docker 官方 GPG 密钥
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

# 4. 添加 Docker 稳定版的 APT 仓库
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

# 5. 更新包列表以包含 Docker 仓库
sudo apt update

# 6. 安装 Docker CE (Community Edition)
sudo apt install -y docker-ce docker-ce-cli containerd.io

# 7. 验证 Docker 是否安装成功并运行
sudo systemctl status docker
# 或者
sudo docker run hello-world # 这个会尝试拉取一个测试镜像并运行

# 8. (可选但推荐) 将当前用户添加到 docker 组，这样就不需要每次都输入 sudo
sudo usermod -aG docker ${USER}
# 然后你需要注销并重新登录，或者在新打开的终端中生效
# newgrp docker # 临时在当前会话中切换到 docker 组
