Chef - add/change a line in a file

I'm new to Chef / Kitchen. I'd like to change a line in a file on the target VM, such like /etc/sudoers - change Defaults ....

That means, I don't want to use template which would overwrite the file - I want to retain the other content of the file.

Ideally I would like some action like this:

file_changeLine '/path/to/file/' do
    prefix: "Defaults .*"
end

Is there something such? I haven't found in docs. Maybe there are some additional repositories with community-made actions?

Solution

  • We really don't recommend this kind of management structure, but if you must, look at the poise-file and line cookbooks on Supermarket. They provide resource-based interfaces for delta updates. Just be aware that this will need a lot of care and feeding as it leads to generally brittle code.
