Is this ok [y/d/N]:

 

命令里已经yum install -y了，但是还是需要选择Y,N没有自动执行，请问这个要怎么破。

PS：我是在Dockerfile里设置，然后进入镜像手动测试，Dockerfile报错如下：

Is this ok [y/d/N]: Exiting on user command
Your transaction was saved, rerun it with:

The command '/bin/sh -c yum update && yum install telnet -y' returned a non-zero code: 1

Answer 1

建议 docker run -it centos /bin/bash 进入容器，然后运行 yum update && yum install wget -y
