Service settings management system (Or Web interface for managing XML \ Yaml) - does this exist in nature?

Question

System administration

There are several applications, there are several platforms. The CI + Ansible + Docker bundle manages the deployment of applications to various platforms. Configurations (in our case, ENV parameters) - are described in YML files for Ansible. The number of applications is growing, the number of platforms is growing.
For example: Appendix A - required parameters b and c, platform X also requires parameters e and f. We can create a new parameter k for the X platform and specify the default value, then in the configuration of a specific application on the platform - this parameter will appear, at startup - we will see all b, c, e, f, k in our env.
In general, we only need some kind of interface (web) that will allow us to manage the settings of our containers on the basis of templates or by inheritance or in some other way. It is not at all necessary that it be able to be friends with ansible \ docker ... we can make friends ourselves - in general, we have already tuned in to write solutions for ourselves on our own, but usually everything has already been invented before us. Who can faced a similar task?
