Script to change node's environment works in shef but not w/knife exec

Chef Infra (archive)
1

This is very strange. Am I doing something that can’t be accomplished
with knife exec?

it works perfectly when I run it from shef on my workstation

usage knife exec ./change_env.rb query environment_name

query = ARGV[0] # i type this in when using shef
new_environment = ARGV[1]

my_nodes = search(:node, “#{query}”)

my_nodes.each do |n|
n.chef_environment new_environment
n.save
end

exit 0

I tried the work around on this ticket
http://tickets.opscode.com/browse/CHEF-1910
nodes.transform("name:NODE_NAME") {|n| n.chef_environment = "ENVIRONMENT"}

but still no joy :frowning:

query=ARGV[2]
new_environment=ARGV[3]

I hard code those values when i use them in shef

sorry misunderstood your question, ARGV[0] and ARGV[1] are correct. I
guess that knife exec shifts the opts when it passes them to the
script

Hi,

Do you get any error messages? How are you determining that the
environment isn't being changed?

query = ARGV[0] # i type this in when using shef
new_environment = ARGV[1]

On recent versions of Chef, this should be ARGV[2] and ARGV[3] as Ranjib said.

my_nodes = search(:node, "#{query}")

my_nodes.each do |n|
n.chef_environment new_environment
n.save
end

exit 0

I tested this basic script using Chef 0.10.8 and it worked as far as I
could tell.

Cheers,

Steven

I see no error messages, none at all. I will look at this again

tks Steve

hmm, i think it works now, u guys were right about the arguments, I
missed that in the midst of multitasking confusion. tks for taking
the time to test it.
