I have 15 servers that I need to set up and configure. I’ve been playing with Ansible a bit and I’ve come very far. I have one last thing to do that I don’t know how to solve, and that is:

Each server has a file called “server.txt”. In this file, the server must contain a certain value to be able to communicate with the master.

I have a file (locally) that has 15 different keys, and I need to ship these keys (on by one) to each server. I can do this manually, but I want to do this with Ansible since the servers will become more and more.

Is there a smart and easy way to do this with Ansible? E.g loop through each line, take the line, and write it to each server?

Since you have provided little information, the only thing I can say is check out lookup
