--------------------------------------------------------------------

This seems to be done in KARAF-3434 and can confirm that this works in Karaf 4.0.3.

The following configuration assigns environment variable FOO to configuration key:
{code}
key=${env:FOO}
{code}

> when using karaf in clouds & PaaS infrastructures like OpenShift, Docker, OpenStack
et al; its common to use environment variables to pass in environment specific values; then
keep a single disk image. It would be nice if there was an easy way to reference environment
variables similar to the ${foo.bar} syntax for accessing system properties.
> Maybe karaf should support some kind of environment variable expansion like 
> {code}
> # define a property based on an env var
> foo = ${ENV.nameOfEnvVar} 
> # e.g. here's the host name
> host = ${ENV.HOSTNAME} 
> {code}
