       nss-mymachines, - Provide hostname resolution for local container



       nss-mymachines is a plugin for the GNU Name Service Switch (NSS) functionality of the GNU
       C Library (glibc), providing hostname resolution for container names of containers running
       locally that are registered with systemd-machined.service(8). The container names are
       resolved to the IP addresses of the specific container, ordered by their scope.

       The module also resolves user IDs used by containers to user names indicating the
       container name, and back.

       To activate the NSS modules, "mymachines" has to be added to the lines starting with
       "hosts:", "passwd:" and "group:" in /etc/nsswitch.conf.

       It is recommended to place "mymachines" near the end of the nsswitch.conf lines to make
       sure that its mappings are only used as fallback, and that any other mappings, such as DNS
       or /etc/hosts based mappings, take precedence.


       Here is an example /etc/nsswitch.conf file that enables mymachines correctly:

           passwd:         compat mymachines
           group:          compat mymachines
           shadow:         compat

           hosts:          files resolve mymachines myhostname
           networks:       files

           protocols:      db files
           services:       db files
           ethers:         db files
           rpc:            db files

           netgroup:       nis
