NAME

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

       A node is any physical, virtual, or cloud machine that is configured to be maintained by a chef-client.

       The knife node subcommand is used to manage the nodes that exist on a Chef server.

COMMON OPTIONS

       The following options may be used with any of the arguments available to the knife node subcommand:

       --chef-zero-port PORT
              The port on which chef-zero will listen.

       -c CONFIG_FILE, --config CONFIG_FILE
              The configuration file to use.

       -d, --disable-editing
              Use to prevent the $EDITOR from being opened and to accept data as-is.

       --defaults
              Use to have knife use the default value instead of asking a user to provide one.

       -e EDITOR, --editor EDITOR
              The $EDITOR that is used for all interactive commands.

       -E ENVIRONMENT, --environment ENVIRONMENT
              The  name  of  the  environment. When this option is added to a command, the command will run only
              against the named environment.

       -F FORMAT, --format FORMAT
              The output format: summary (default), text, json, yaml, and pp.

       -h, --help
              Shows help for the command.

       -k KEY, --key KEY
              The private key that knife will use to sign requests made by the API client to the Chef server.

       --[no-]color
              Use to view colored output.

       --print-after
              Use to show data after a destructive operation.

       -s URL, --server-url URL
              The URL for the Chef server.

       -u USER, --user USER
              The user name used by knife to  sign  requests  made  by  the  API  client  to  the  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.

       -v, --version
              The version of the chef-client.

       -y, --yes
              Use to respond to all confirmation prompts with "Yes". knife will not ask for confirmation.

       -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.

BULK DELETE

       The bulk delete argument is used to delete one or more nodes that match a pattern defined  by  a  regular

          $ knife node bulk delete "^[0-9]{3}$"

       Type Y to confirm a deletion.

CREATE

       The  create  argument  is  used to add a node to the Chef server. Node data is stored as JSON on the Chef
       server.

          ## sample:
          {
             "normal": {
             },

          Node Name:   build
          Environment: _default
          FQDN:
          IP:
          Run List:
          Roles:

       To show basic information about a node, truncated and nicely formatted:

          knife node show <node_name>

       To show all information about a node, nicely formatted:

          knife node show -l <node_name>

       To list a single node attribute:

          knife node show <node_name> -a <attribute_name>

       where <attribute_name> is something like kernel or platform. (This doesn't  work  for  nested  attributes
       like node[kernel][machine] because knife node show doesn't understand nested attributes.)

       To view the FQDN for a node named i-12345678, enter:

          $ knife node show i-12345678 -a fqdn

       to return:

          fqdn: ip-10-251-75-20.ec2.internal

       To view the run list for a node named dev, enter:

          $ knife node show dev -r

       To view information in JSON format, use the -F common option as part of the command like this:

          $ knife role show devops -F json

       Other formats available include text, yaml, and pp.

       To view node information in raw JSON, use the -l or --long option:

          knife node show -l -F json <node_name>

       and/or:

          knife node show -l --format=json <node_name>
