              **Summary:** post data to url

              This module can be used to post data to a remote host after boot is complete.
              If the post url contains the string ``$INSTANCE_ID`` it will be replaced with
              the id of the current instance. Either all data can be posted or a list of
              keys to post. Available keys are:

                  - ``pub_key_rsa``
                  - ``pub_key_ecdsa``
                  - ``pub_key_ed25519``
                  - ``instance_id``
                  - ``hostname``
                  - ``fdqn``

              **Internal name:** ``cc_phone_home``

              **Module frequency:** per instance

              **Supported distros:** all

              **Config keys**::
