Chef Solo get user input

问题

I don't know why I can't find anything on the interwebs about this.

I basically want to write a recipe that prompts a user for their github username/password, then posts to the github API to add an ssh key.

I'm sure I can prompt a user with normal ruby methods (ie gets) but this doesn't seem natural given all the utilities chef provides.

Can someone tell me a 'chef' way of prompting a user for input to store in vars for later use?

I'd like to first output some instructions for the user to read, then get the username, then password, I guess for safety reasons, the password should not be shown on the console as they type

回答1:

I'd say chef is not made for such user input.

You might use ruby code that is executed during the compile phase of the chef run, but I'd suggest the following:

What about reading it from an environment variable?

回答2:

It feels super dirty, but this actually works. Maybe some things can be tuned so that it feels a bit more clean:

file "/tmp/ans" do
  puts "Enter something useful!"
  content ::STDIN.readline
end

You can apply such a recipe with chef-apply, note that using Vagrant will not work.

Still, I would recommend do it differently. Another way would be to not call chef directly, but through a wrapper script. This could read the data from the user and write it into a json file, which is then given to chef via the -j PATH, --json-attributes PATH parameter (see chef-solo parameters).
