About
Config::Maker is perl program, that generates text files from templates
and configuration values. It is useful to keep all configuration in one
place and configure many different services from that. I wrote it and
use it for generating firewall configuration, DNS zone file and dhcp
server config for a small network.
The idea is a combination of Embperl and XSLT, except it's not that
heavyweight. The template is copied to the output, while substituting
directives with respective values from the configuration. The values are
refered with paths, that are similar to XPath, but a bit less
featurefull.
Instalation
This module uses Module::Build infrastructure for building. To build it,
unpack the source tarball, enter the directory and type:
perl Build.PL
./Build
./Build install
For various options available, please refer to the Module::Build(3pm)
documentation.
A Makefile.PL is provided for backwards compatibility. To use it, unpack
the source tarball, enter the directory and type:
perl Makefile.PL
make
make install
For various option available, please refer to the
ExtUtils::MakeMaker(3pm) documentation.
The later method (and both methods in newer versions) is understood by
the CPAN shell (see cpan(1)). You can use that to install.
Using
The program is normaly invoked via the "configit" script. It takes a
metaconfig as an argument, which governs all the generation. In the
metaconfig, a list of configuration sources (files) is given and for
each a list of templates that should be instantiated (also files) are
given. Result of expanding a template can be saved to a file, piped to a
command, or possibly both. If an error is encountered anywhere during
the processing, the results are not installed so the previous
configuration is not broken. For details refer to configit(1).
There is one additional auxiliary script, "run-and-save". It is useful
if you generate a script, that shall be run on another machine. Just
install the "run-and-save" script on the target machine and specify "ssh
*machine* run-and-save --act *target-script-name*" as a "command" for
given template. This script installs your script as *target-script-name*
and executes it. Don't forget to end your template with "#COMMIT" to
indicate that whole script was transfered. The "run-and-save" script can
also take the name from first line of input.
