Is this ok [y/d/N]:

I want to hit "Y" by command. Is there any other way ?

Thanks

Answer 1

Use the -y option to yum, like this:

yum -y install varnish

This will automatically answer yes on any questions during the install.

Answer 2

Actually, don't use yum directly on Elastic Beanstalk for anything but research and debugging, as the changes won't stick if Elastic Beanstalk decides to scale or rebuild the environment.

If you need a specific package on your instance, you probably want to install it through .ebextensions and the packages: directive, like so:

packages:
    yum:
        varnish: []

Good luck!
