Hi All,

While trying out environments in chef, I tried some steps as mentioned below  
for better understanding usage of environments but could not get why the result  
was something different then what I expected.

Here is what I have tried :

1. I have a recipe. consisting variable x = 5 defined in attributes/attr.rb

2. Then, I created a environment named “testing” for my cookbook named “try”.  
In this newly created environment, I have specified overirde\_attributes  
variable x=10

3. We know that “knife node edit \<node\_name\>” command can be used to edit the  
details of a node. So, moving ahead I edited environment attribute of node  
"client\_one" from “\_default” to that “testing”

4. Now, my expectation was that if I execute recipe “try” against this node it  
should read and print the value of x as 10 but output printed was 5.

Please let me know how the execution in this scenario does not read value of  
variable x from environment.

Thanks

It really depends on what the recipe is printing.. default['try']['x]?  
node['try']['x']? Something else?
