libnss_mymachines.so.2: Provide hostname resolution for local container instances.
NAME
nss-mymachines, libnss_mymachines.so.2 - Provide hostname resolution for local container instances.
SYNOPSIS
DESCRIPTION
nss-mymachines is a plugin for the GNU Name Service Switch (NSS) functionality of the GNU C Library (glibc) providing hostname resolution for containers running locally, that are registered with systemd-machined.service(8). The container names are resolved to IP addresses of the specific container, ordered by their scope.
To activate the NSS modules, "mymachines" has to be added to the line starting with "hosts:" in /etc/nsswitch.conf.
It is recommended to place "mymachines" near the end of the nsswitch.conf line to make sure that this mapping is only used as fallback, and any DNS or /etc/hosts based mapping takes precedence.
EXAMPLE
Here's an example /etc/nsswitch.conf file, that enables mymachines correctly:
-
passwd: compat group: compat shadow: compat hosts: files dns mymachines myhostname networks: files protocols: db files services: db files ethers: db files rpc: db files netgroup: nis
