Jean-Baptiste Onofré commented on KARAF-4609:
---------------------------------------------
I mean something slightly different. The purpose is really to override an
existing value. For instance, in {{etc/my.cfg}} file, I have:
{code}
my.port=7777
{code}
That's the default value. However, the idea is to be able to override such
configuration property at startup using {{-Dmy;my.port}} for instance. It's
convenient to override existing property when running in Docker.
I guess you meant that we can already use System property, but it means that
the {{cfg}} file has to be "prepared for that", like:
{code}
my.port=${MY_PORT}
{code}
Right ?
