Once environments have been created, we will need to ensure that the nodes are correctly associated with the environments. Again, as with the management of environments, there are multiple ways to associate a node with an environment.

$ knife node edit node01
This will open up the corresponding node01 object's JSON in the text editor. Add/edit the chef_environment property with the right environment name and save the file to apply the changes:
