NAME

       knife-role - The man page for the knife role subcommand.

       A  role  is  a way to define certain patterns and processes that exist across nodes in an organization as
       belonging to a single job function. Each role consists of zero (or more) attributes and a run-list.  Each
       node  can  have zero (or more) roles assigned to it. When a role is run against a node, the configuration
       details of that node are compared against the attributes of the role,  and  then  the  contents  of  that
       role's  run-list  are applied to the node's configuration details. When a chef-client runs, it merges its
       own attributes and run-lists with those contained within each assigned role.

       The knife role subcommand is used to manage the roles that are associated with one or  more  nodes  on  a
       Chef server.

              Authentication will fail if the user name does not match the private key.

       -V, --verbose
              Set for more verbose outputs. Use -VV for maximum verbosity.

       -z, --local-mode
              Use  to  run  the  chef-client  in local mode. This allows all commands that work against the Chef
              server to also work against the local chef-repo.
