I have a cookbook which is available on a private chef supermarket and I have 4 chef servers which need this cookbook to be available so that corresponding nodes can consume it.
We can use berks install and berks upload multiple times to achieve this. Is there a simpler way to do this?
If it is not possible, why does chef not allow this?
if you have 4 different chef servers, then i assume that you are using 4 different keys for authentication when you interact with the chef server. this implies that you have 4 different configurations which is used in the process.
there is no tool which i know of that for each configuration it uploads the cookbook to chef server.
so for your question, you should upload your cookbook to each chef server individually.
