I've been working to set up an external returner on the master side for my Saltstack deployment -- a 'master_job_cache', as specified in the documentation.

I started with Slack and mongo_return. I quickly discovered that neither of these work with master_job_cache. My understanding is that they do not implement the right functions to make this work, particularly save_load (revelaed through searching and reading the logs). I then tried mongo_future_return, given that it implements the correct functions -- with the understanding that according to the docs it is currently unstable. I've got pymongo installed and my master-side configuration looks like this:

returner: mongo_future_return

mongo:
    db: salt_returns
    host: 194.168.1.4
    user: salt_master
    password: solidWellBuiltPassword
    port: 27017

master_job_cache: mongo_future_return

However, this results in a stack trace when I run it, with the master side logs telling me: 

 Could not deserialize msgpack message.This often happens when trying to read a file not in binary modeTo see message payload, enable debug logging and retry. Exception: unpack(b) received extra data.

So, first question: given what I've explained so far, is there anything I appear to be doing incorrectly that I should address in order to make these mongo returners work?

Second, and main question: what returners have worked for you with the master_job_cache option? Is there a list of those THAT WORK WITH MASTER JOB CACHE (I know there is a list of returners, many don't specify). I don't have the time to try each one individually, though I will likely give MySQL and Postgres a shot.

Thanks for your help in advance.

I've used the MySQL master job cache successfully many times.

  • The question wasn't "have you used it". It was "which returns have you used it with". – Jenny D May 12 '17 at 08:14

    HI @Utah_Dave, thanks for the response. I've actually decided to go with the Postgresql master job cache, and it's working beautifully. Thanks for your work on Saltstack, I love the product, it's become a core pillar of our automation strategy. I'm going to leave this question up for a little bit and see if it accumulates any additional relevant info. Cheers! – Mr.Budris May 12 '17 at 13:12
  • @JennyD, I've used the MySQL master job cache, which is the MySQL returner. I'm not sure how I'm not answering his question. – Utah_Dave May 15 '17 at 21:37
