Hi,

I use knife exec to update attributes values.

Something like this:

knife exec -E 'nodes.find(:name => "node_name") {|n| n.set[attribute_name] = attribute_value ; n.save }

Hope it helps

Michel

We wrote our own knife plugin a few years ago but since then several have popped up on github,  A quick search revealed:

 

https://github.com/mrtazz/knife-node-attribute

https://github.com/amian84/knife-set-attribute

https://github.com/pdf/knife-attribute

 

This is by no means complete or an endorsement of any of these.

I’m aware of the -j option to set node attributes during bootstrap. I’m also aware of knife edit, which is needs user input form an editor. This is NOT what I’m talking about

 

If a node is already bootstrapped, how can I set some of its attributes without re-bootstrapping it, and not using knife edit. I know I can do the following in a script since I want to do this automagically.

-        Knife ode show –Fj > node.json

-        Edit the node.json file

-        Knife node from file node.json

Is there a more elegant way?
