【转】在 Ubuntu 上安装 Docker CE 及 Docker-compose

原文来自：https://hackmd.io/@rpwis/SJSaav9Fj ，本文稍作修改，以适应Ubuntu的使用

• CE: Community Edition

1. 安装依赖

sudo apt update
sudo apt -y install apt-transport-https ca-certificates curl gnupg2 software-properties-common

1. 加入 Docker 官方的 GPG key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/trusted.gpg.d/docker-archive-keyring.gpg

1. 下载 Docker CE 的 repository

sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

1. 安装 Docker CE 和 docker-compose

sudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io -y
# 启动 docker
sudo systemctl enable --now docker
# 安装 docker-compose
sudo apt install -y curl wget
curl -s https://api.github.com/repos/docker/compose/releases/latest | grep browser_download_url  | grep docker-compose-linux-x86_64 | cut -d '"' -f 4 | wget -qi -
chmod +x docker-compose-linux-x86_64
sudo mv docker-compose-linux-x86_64 /usr/local/bin/docker-compose

1. 新增当前用户到 docker

sudo usermod -aG docker $USER
newgrp docker

1. 测试是否成功，输入docker version看到有 Server 项即为成功，看不到就表示使用者没有权限看到 Server 的选项，第五步失败。

$ docker version

$ docker-compose version
