NSS Module which supports wildcards

xhosts

xhosts is a NSS module which resolves host names. It is similar to the default files module which reads records from /etc/hosts but it allows to configure wildcard records.

Example

• /etc/xhosts

# local k8s test
*.cluster.local 172.18.0.2

# other entry
other.foo.com 192.168.1.1

Installation

• Build the code and install the shard library libnss_xhosts.so.2 in your library path:

./install.sh

• Add xhosts to your hosts configuration in /etc/nsswitch.conf:

hosts:          files xhosts dns

• Create the file /etc/xhosts and add your records:

*.cluster.local 172.18.0.2
