centos7 安裝docker-compose及加速

• 首先是官方安裝(一般會因爲網絡原因失敗)

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

• pip3安裝

yum install python3-pip
pip3 install docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose -v

• 加速

鏡像拉取一直報錯：

Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

• 解決方法：

vi /etc/docker/daemon.json

{
 "registry-mirrors": ["https://registry.docker-cn.com"]
}

• 重啓docker

systemctl daemon-reload
systemctl restart docker
