NSS-MYMACHINES(8)               nss-mymachines               NSS-MYMACHINES(8)
NAME
       nss-mymachines, libnss_mymachines.so.2 - Provide hostname resolution
       for local container instances.
SYNOPSIS
       libnss_mymachines.so.2
DESCRIPTION
       nss-mymachines is a plug-in module for the GNU Name Service Switch
       (NSS) functionality of the GNU C Library (glibc), providing hostname
       resolution for the 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. This functionality only applies to containers using
       network namespacing.
       The module also resolves user and group IDs used by containers to user
       and group names indicating the container name, and back. This
       functionality only applies to containers using user namespacing.
       To activate the NSS module, add "mymachines" to the lines starting with
       "hosts:", "passwd:" and "group:" in /etc/nsswitch.conf.
       It is recommended to place "mymachines" after the "files" or "compat"
       entry of the /etc/nsswitch.conf lines to make sure that its mappings
       are preferred over other resolvers such as DNS, but so that /etc/hosts,
       /etc/passwd and /etc/group based mappings take precedence.
EXAMPLE
       Here is an example /etc/nsswitch.conf file that enables nss-mymachines
       correctly:
           passwd:         compat mymachines systemd
           group:          compat mymachines systemd
           shadow:         compat
           hosts:          files mymachines resolve [!UNAVAIL=return] dns myhostname
           networks:       files
           protocols:      db files
           services:       db files
           ethers:         db files
           rpc:            db files
           netgroup:       nis
