docker pull rabbimq镜像失败

在使用docker pull rabbitmq的镜像的时候，找了好多源，都报错如下：

Error response from daemon: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit

解决办法：

修改vim /etc/docker/daemon.json如下：

{
  "registry-mirrors": ["https://plqjafsr.mirror.aliyuncs.com"],
}

systemctl daemon-reload && systemctl restart docker
