说一下centos环境下安装工具啊，不能使用yum.

https://www.runoob.com/docker/centos-docker-install.html

像这样docker run learn/tutorial apt-get install -y ping ，只是安装一个工具到容器中，请问如果需要安装多个工具该如何操作呢

出现
Reading package lists...
E: Unable to locate package ping
Building dependency tree...
Reading state information...
先进入容器 docker run -t -i ubuntu
apt-get update
apt-get upgrade
apt install iputils-ping # ping

docker run hello-world apt-get install -y ping 报错，信息如下：
container_linux.go:247:starting container process caused"exec::\"apt-get\":executable file not found in PATH$"

你这是在centos下运行的这个命令，不是ubunto
