sudo docker pull prom/node-exporter
sudo docker run --rm --name=node-exporter -p 9100:9100 -d prom/node-exporter
其中，–rm参数表示容器退出时自动删除容器，–name参数指定容器的名称，-p参数将容器内的9100端口映射到主机的9100端口，-d参数表示在后台运行容器。
sudo docker pull prom/prometheus

ubuntu20.04系统docker权限报错
https://blog.csdn.net/jasdhasd/article/details/131054044
1、添加docker group
sudo groupadd docker
如果docker组已经存在，可能会出现这个提示：groupadd: group ‘docker’ already exists

2、将用户名“username@主机名”加到docker group中
sudo usermod -aG docker username
3、重启系统
