Ubuntu安装Docker和Docker Compose指南

1. 准备工作

sudo apt update
sudo apt install apt-transport-https ca-certificates curl software-properties-common

2. 安装Docker

1. 添加Docker GPG密钥

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

1. 设置Docker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

1. 安装Docker

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

1. 验证安装

sudo docker run hello-world

3. 安装Docker Compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

验证安装

docker-compose --version

4. 配置Docker权限

1. 创建docker组并添加用户

sudo groupadd docker

sudo usermod -aG docker $USER

2. 应用组更改

newgrp docker

3. 验证非root用户权限

docker run hello-world

注意: 配置权限后可能需要注销并重新登录或重启系统以使更改生效。
