Management of ``/etc/hosts`` is controlled using ``manage_etc_hosts``. If this is set to false, cloud-init will not manage ``/etc/hosts`` at all. This is the default behavior. If set to ``true`` or ``template``, cloud-init will generate ``/etc/hosts`` using the template located in ``/etc/cloud/templates/hosts.tmpl``. In the ``/etc/cloud/templates/hosts.tmpl`` template, the strings ``$hostname`` and ``$fqdn`` will be replaced with the hostname and fqdn respectively. If ``manage_etc_hosts`` is set to ``localhost``, then cloud-init will not rewrite ``/etc/hosts`` entirely, but rather will ensure that a entry for the fqdn with a distribution dependent ip is present in ``/etc/hosts`` (i.e. ``ping <hostname>`` will ping ``127.0.0.1`` or ``127.0.1.1`` or other ip). .. note:: if ``manage_etc_hosts`` is set ``true`` or ``template``, the contents of ``/etc/hosts`` will be updated every boot. to make any changes to ``/etc/hosts`` persistant they must be made in ``/etc/cloud/templates/hosts.tmpl`` .. note:: for instructions on specifying hostname and fqdn, see documentation for ``cc_set_hostname`` **Internal name:** ``cc_update_etc_hosts`` **Module frequency:** per always **Supported distros:** all **Config keys**:: manage_etc_hosts: <true/"template"/false/"localhost"> fqdn: <fqdn> hostname: <fqdn/hostname> i����( t templater( t util( t PER_ALWAYSc C s* t j | d t � } t j | d d g �r� t j | | � \ } } | s\ | j d � d S| j d | j j � } | s� t d | j j � � n t j | d i | d 6| d 6� nn | d k rt j | | � \ } } | s� | j d � d S| j d � | j j | | � n | j d | � d S( Nt manage_etc_hostst addonst templates<
