Using variables in org.apache.karaf.features.cfg
I have a use case where I want to move the list of boot features (the
"featuresBoot" property) from "org.apache.karaf.features.cfg" into
"custom.properties". The reason is that our custom server comes with a
great number of features but each customer only uses some of them. To allow
for easy customisation (and upgrades) I put everything related to a
specific installation in a custom.properties file (that I put outside the
Karaf home directory). I can then easily see how this installation is
customised and I can easily upgrade by simply replacing the entire Karaf
installation and keep the customisation (since it is located outside Karaf).
However, it seems I cannot use variables defined in "custom.properties"
in "org.apache.karaf.features.cfg". In fact, I cannot even define a
variable in "org.apache.karaf.features.cfg" and then use it in the same
file.
How come? Isn't FileInstall used for
parsing "org.apache.karaf.features.cfg"?
How can I use custom variables in "org.apache.karaf.features.cfg"?
I use Karaf 2.3.0 with Java 6 on Windows 7.

I meant xxx.logging.cfg and custom.properties; was just at a customer with
no local karaf to check :-)
OK, can you please provide a bug report? I can check on it tomorrow.

Hello Andreas,
Yes, the example with the features file (org.apache.karaf.features.cfg)
doesn't work but should.
I'm not sure what the log.cfg and the custom.settings files are. However, I
do this in my org.ops4j.pax.logging.cfg:
log4j.appender.info.file=${logdir}/info.log
And I put this in the custom.properties:
logdir=data/log
I use that mechanism in several configuration files, e g:
- org.ops4j.pax.web.cfg
- org.apache.karaf.management.cfg
- org.apache.karaf.shell.cfg
The above gives me the possiblitly to manage all the ports in one place
(custom.properties) - which is very convenient.
But for some reason this mechanism doesn't work
for org.apache.karaf.features.cfg.

Re: Using variables in org.apache.karaf.features.cfg
Posted by Andreas Pieber <an...@gmail.com>.
well, checking the code I would say there's no difference to the other .cfg
files. I'm even not sure if it's a bootstrap error. How exactly can I
reproduce the problem?
in the features file:
featuresRepositories = ${var}
and in custom.properties
var =
"mvn:org.apache.karaf.features/standard/3.0.0-SNAPSHOT/xml/features,mvn:org.apache.karaf.features/enterprise/3.0.0-SNAPSHOT/xml/features,mvn:org.apache.karaf.features/spring/3.0.0-SNAPSHOT/xml/features"
this shouldn't work, but e.g.
in log.cfg
pattern = ${abc}
and in custom.settings
abc = "%d{ISO8601} | %-5.5p | %-16.16t | %-32.32c{1} | %X{bundle.id} - %X{
bundle.name} - %X{bundle.version} | %m%n"
works?
Kind regards,
Andreas

What I've tried to do in org.apache.karaf.features.cfg works with other
configuration files. File install does support this. It's the way I handle
most of my tailored configurations in my custom server.
However, there seem to be something special
with org.apache.karaf.features.cfg since the same mechanisms dont work
there. That's why I wondered whether file install was used for installing
the "features" feature or if it was done by some other means. Could it be a
bootstrap problem?

Re: Using variables in org.apache.karaf.features.cfg
Posted by Andreas Pieber <an...@gmail.com>.
Hey,
I'm afraid this is currently not really possible. The custom.properties is
written into the System.setProperty while the fileinstall (but I've only
checked the code only shortly) does not access this sort. I think to make
this available would require a patch to fileinstall.
@Everybody with more knowhow about the fileinstall internals: feel free to
correct me :-)
Kind regards,
Andreas
