[chef] Re: Re: Re: RE: Running chef in multiple environments

[Scott Hain < >]

There are other ways of setting this up - I've seen a successful example of automated promotion using a few complicated "version pinning" mechanisms, both via environment and 'wrapper' cookbook. The key thing I noted in each of the situations where this was successful was a well defined promotion path for each cookbook as it makes its way through the environments AND some kind of automation (be it in CI or just scripts or whatever) that enforce this.

I've seen first-hand an attempt to 'promote' cookbooks between multiple chef servers and that got ugly really fast (not to say it's not possible).

Personally I've found the concept of a 'wrapper' cookbook that you can version independent of the version of the cookbook they pull in to be successful, but your mileage will vary depending on your node setup/cookbook setup/workflow, etc.
