Searching with chef


#1

Hi guys -

I’m struggling a bit with searching within chef…

I’m trying to select all nodes that have a given role in a particular
environment.

I realize I can do something like:

knife search node “roles:” -E

But how do I get things like the ip address from that object?


#2

Try this:

knife search node “roles: AND
’chef_environment:” -a ipaddress

-M

on the CLI, you can pass the ‘-a / --attribute’ flag to get a
particular attribute tree from the object.

In the recipe, it’ll look something like

servers = search(:node, “roles:bar AND chef_environment:production”)
server = servers.first
ip = server[‘ipaddress’] # Just a Chef::Node object here.

Check out Heavy Water’s discovery cookbook for some recipe helpers,
like ‘empty ok?’, local node fall-back, environment aware search, sort
by check-in time & cloud-aware IP addressing preferences. [0]

I wonder if we should move some of that into the core DSL. Super useful,
non intrusive.

+1 for environment scoped searches.

I would be on-board with that; Discovery has always been positioned
this way. Potentially with support for Partial searches?

Oh yeah - I just assumed you were already on the partial search train. You
heavywater guys sure are lazy!
