Description

Hello,

At the moment, the rendering of a Jinja2 template fails on a server without python-jinja2.

Could it be possible to add the library either:

- In the dependencies of the rudder-agent package ;
- Through a promise, when it's needed.

Thanks.

We'd rather avoid having rudder-agent depend on Python for just one generic method. We already require Perl (for the inventory), and would like to limit requirements.

- Through a promise, when it's needed.

This could be a good alternative. Maybe a call to package_present("python-jinja2") in the template jinja2 ncf method?

make it a -recommend for the package?

- Through a promise, when it's needed.

should at least be automatic: IF a NCF technique is using the method, have a specific error to be returned if missing, or add a correct flag in the system techniques.
It should not just hit a wall and let the user figure out that "oh, no sorry, you could click this but it won't work"

Personally, I think rudder has to sort it out. NCF is the users' interface, he should not be required to debug (and log on) to the system.
For me the warning in the docs was good and on time, but really, let the system techniques or NCF sort it out.

The recommand is a good idea. We could list all non mandatory dependencies as such, and explains for what they are recommanded.

The need to see the system log is also a problem. We should at bare minimum at least report on the compliance report "Error: missing mandatory dependency on the system: XXXX. Please install python-jinja2 (or whatever)" so that the user can immediately know how to solve the problem without having to explore.
