It would be nice to be able to initialize the local integration (e.g. secret management) before the explorers are executed against the target host. I haven't seen anything relevant in the doc - but there might be an easy way to hook this in the code.

I'll investigate and implement and/or document if needed.

@fnux We discussed this many, many, many years ago and called it "stages". There might be some discussion content still left in the doc/ folder of cdist.

The "TL;DR" was, afair:

  • good idea
  • Best to have it before and after

As of today I'd think about something like this:

  • new hooks/ directory
  • new hooks/pre, hooks/post directory
  • Leaving room for other hooks in the future
  • Executing scripts / binaries in those directories in "glob" order (i.e. python deterministic)

One thing that needs to be taken into account is which variables should be exported to these scripts and clearly also documented...

Also to consider whether those hooks are run before/after on a "per host* or per run basis if you are running in parallel mode (I see advantages for both).

Just my 49 Rappen.

That sounds pretty good. I will see if I find some time to implement an initial version.
