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

             Summary: make it easy to access environment variables inside karaf configuration
properties files
                 Key: KARAF-2466
                 URL: https://issues.apache.org/jira/browse/KARAF-2466
             Project: Karaf
          Issue Type: Improvement
            Reporter: james strachan
             Fix For: 2.4.0


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 ${ENV.nameOfEnvVar}
such as ${ENV.HOSTNAME} to get the current host name on unix?
