Question

我是docker的新手，并试图在centos 7.1上使用chef实现docker 下面是我为安装，拉动centos图像和创建容器而编写的基本代码。

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手动启动。当我检查docker ps时，我发现容器未启动。我试了好几次但是无法启动容器。

使用厨师的Docker代码

docker_service 'default' do
  action [:create, :start]
end

docker_image 'centos' do
  action :pull
end

docker_container 'check2' do
  repo 'centos'
  action :create
end

请你帮帮我

Answer 1

默认情况下，centos图片将运行/bin/bash，该图片将立即退出，而不会显示tty（-t）和标准输入（-i）。

尝试在容器中运行

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

无法启动容器
