$ knife node environment_set node01 production

This will set the environment for node01 as production. The next time chef-client executes on the node, it'll apply the configuration corresponding to the production environment on node01.

We can also edit the node object itself and set the chef_environment property with the required environment name as follows:

$ 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:
