If your question is either

  • Can I pass some values as parameter when launching chef-client ? or
  • Can I ask for use inputs while running chef client?

You can not do such things. And its not chef's way. Chef is supposed to be run in non-interactive style with no user inputs at the run time. In fact, if you have a program which needs user inputs, you need to make it run non interactively or provide answers file. Now this answers file can be made dynamic with templates + attributes. Thats what you should do.

If you are looking for taking user inputs while running chef client though, you are better off considering tool such as Ansible which supports that. However, that will not make your scripts run on windows and so on.

Generally dynamic values are passed in via the node, environment, or roles Each location allows you to set attributes on the node at various precedent levels. Alternately, you can also use databags, or calculate the values based on ohai data. With more details of your use case, we may be able to point you to the most appropriate solution.
