【docker】拉取镜像报证书错误：error pulling image configuration: download failed after attempts=6: tls: failed t

在使用docker时，采用阿里云镜像源时会出现pull失败情况：

解决办法：

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://yxzrazem.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
