docker pull 拉取失败更换源

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.conf <<EOF
{
    "registry-mirrors": ["https://do.nark.eu.org"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

然后出现下面的错误
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running

找到一个更改json为conf的重启可以了
mv /etc/docker/daemon.json /etc/docker/daemon.conf
sudo systemctl daemon-reload
sudo systemctl restart docker

docker pull do.nark.eu.org/library/alpine:latest
