Getting the location of the manifest file

[Go Iwai]

Hello,

I want to know the location where puppet-apply locally applied the
manifest file.

$ pwd
/path/to/manifests
$ puppet apply file.pp

In this case above, can I anyhow get the location of
/path/to/manifests/file.pp within file.pp?

Kind regards,
Go

Hi Go,

what do you want to achieve?
When using puppet apply, a manifest can be anywhere on the filesystem.

Best,
Martin

Hi Go!

I'm not sure what you're trying to accomplish, but you'd probably be better off locating your code in a module on your modulepath and then Puppet takes care of all the relative paths for you. https://puppet.com/docs/puppet/latest/modules_fundamentals.html

Hello Martin,

Let's say we have three directories:

preproduction/ preproduction/ private/

There are different manifest files saved in the same name, like
service-deploy.pp.

In the manifest service-deploy.pp, I want to get the absolute path to
itself, then determine the variable of env like:

$dir = dirname($file) # $file is absolute path to service-deploy.pp
like: '/path/to/manifests/preproduction/service-deploy.pp'
$env = split($dir, '/')[-1]

Then, hiera dynamically maps the correspond yaml file under the $env like:

mapped_paths: [services, svc, "environments/%{env}/%{svc}.yaml"]

This is what I want to realise. I know puppet has already provided a
switch in response to $environment, e.g.,
/etc/puppetlabs/code/environments/production. In this way, I have to
maintain some branches in parallel. That is what I don't want to do.

Kind regards,
Go

Hiera provides an environment hierarchy. Is that what you're looking for? https://puppet.com/docs/puppet/latest/hiera_config_yaml_5.html

No, it is not. I know that the environmental hierarchy provided by hiera realise what I want to do but I don't want to do with that.

Let me restate the question. How can we get the absolute path of the manifest file in itself?

% pwd

/xxx/yyy

% puppet apply ../zzz/manifest.pp

In this example above, I would get the /xxx/zzz/manifest.pp in the manifest somehow.

Kind regards,

Go
