Christian Schneider commented on FELIX-5924:
--------------------------------------------
To be honest I would not use placeholders in default config values.
Instead what I had in mind was to be able to override any config value using an
env variable. So the syntax would be like:
export my.pid.mykey=myvalue
These overrides should then be merged with the default values before applying
the defaults to make sure the config is written only once.
> Allow to provide/override config key values using env variables

> Key: FELIX-5924
> URL: https://issues.apache.org/jira/browse/FELIX-5924
> Project: Felix
> Issue Type: Bug
> Components: Configurator
> Affects Versions: configurator-1.0.4
> Reporter: Christian Schneider
> Priority: Major
> Fix For: configurator-1.0.6
>
>
> The old configurer allowed to override key/values using env variables. This
> is very suitable when depolying using docker as it is a standard approach
> there.
> I propose we also support this for configurator. The data provided in env
> should override eventual default configs provided inside bundles.
> If possible we should make sure that the config is still only created once so
> services do not oscilate.
> With some pointers I might be able to provide a PR for this.
