install docker and compose

engine

https://docs.docker.com/engine/install/

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

compose

https://docs.docker.com/compose/install/

apt install docker-compose

注意

docker安装完毕后会自动创建一个docker group, 添加用户进入到该组, 否则每次执行指令都需要sudo权限.

sudo gpasswd -a $USER docker     	#将登陆用户加入到docker用户组中
newgrp docker     								#更新用户组
# 运行这个镜像测试docker的安装
docker run hello-world
# 如果出现权限问题 则是‘~/.docker/’目录收到了sudo权限的影响
sudo chown "$USER":"$USER" /home/"$USER"/.docker -R
sudo chmod g+rwx "$HOME/.docker" -R
