.SH "NAME"
|
|
nss-mymachines, libnss_mymachines.so.2 \- Provide hostname resolution for local container instances\&.
|
|
.SH "SYNOPSIS"
|
|
.PP
|
|
libnss_mymachines\&.so\&.2
|
|
.SH "DESCRIPTION"
|
|
.PP
|
|
\fBnss\-mymachines\fR
|
|
is a plugin for the GNU Name Service Switch (NSS) functionality of the GNU C Library (\fBglibc\fR) providing hostname resolution for containers running locally, that are registered with
|
|
\fBsystemd-machined.service\fR(8)\&. The container names are resolved to IP addresses of the specific container, ordered by their scope\&.
|
|
.PP
|
|
To activate the NSS modules,
|
|
"mymachines"
|
|
has to be added to the line starting with
|
|
"hosts:"
|
|
in
|
|
/etc/nsswitch\&.conf\&.
|
|
.PP
|
|
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\&.
|
|
