Hi all,
Some time ago I wrote a small bundle that provides a Configuration Admin
plugin to substitute placeholders in configuration items with values
obtained from the local file system. It was initially developed to obtain
Kubernetes secrets, which surface as local files in the running container.
For example, a configuration PID could be configured in ConfigAdmin like
this:
com.my.database:
"user": "my-user",
"password": "$[secret:db.password]"
With this plugin configured, the value for password is picked up by the
Configuration Admin plugin from a local file called 'db.password'. The
entire content of the file is used as value. The file itself can be found
in a configurable location.
The bundle is quite simple, and while I developed it for a K8s use-case it
does not have any K8s dependencies, and would probably also apply to other
use-cases, maybe with some modifications or enhancements.
What do you think? Would this be an interesting contribution to the Felix
codebase?
Best regards,
David Bosschaert
