ansible-pull, and upgrading ansible

[Stephen Tan]

Hi all

I have an interesting situation which I think the very clever people here could probably help me with.

Our use case for ansible:

- We use ansible pull which runs a local connection. It allows us to scale nicely without the need for a master host.

- ansible pull is set in a cron job that runs every hour locally

- We want to be able to upgrade ansible in place ( the best practice is to nuke our current machine and replace with a fresh packer based image but sometimes that's not the available solution )

- If we do this with ansible, then ansible will shoot itself in the head - a chicken and egg situation

Basically, I'm asking - are there any best practices that someone can recommend for upgrading ansible using ansible? 

- Perhaps there is some cunning way using vitualenv?

- Or we can get ansible to trigger it's own upgrade using cron or some other mechanism? ( The problem is then if ansible is running when this job is run ..... )

There is huge kudos for the people with a nice clean, elegant solution! :)

many thanks in advance

Stephen
