无法启动容器

我是新来的docker工人，试图在厨房中使用docker 7.1以下是我为安装，拉动centos镜像和创build容器而写的基本代码。

所有3个任务都成功执行。 由于容器处于停止模式，我尝试通过键入docker start containerid来手动docker start containerid 。 当我检查docker ps我发现容器没有启动。 我尝试了几次，但无法启动容器。

docker代码使用厨师

 docker_service 'default' do action [:create, :start] end docker_image 'centos' do action :pull end docker_container 'check2' do repo 'centos' action :create end

你能帮我吗？

默认情况下， centos映像将运行/bin/bash ，它将立即退出，而不会提供tty（ -t ）和标准input（ -i ）。

尝试在容器中运行一些东西

 docker_container 'check2' do repo 'centos' command 'top -b -d 5' end
