configuring karaf dynamically

Hi. I've some problem in understanding how karaf dynamic configuration
works from
https://cwiki.apache.org/KARAF/48-configuration.html

Now if I do a config:list on my karaf, i can't see a lot of properties
I've set in etc/config.properties, for examples, like all http service
properties (host name, ports...)

For example I've added these lines at the end of etc/config.properties

org.osgi.service.http.port=8181
org.osgi.service.http.secure.enabled=true
org.ops4j.pax.web.ssl.keystore=${karaf.base}/keystore
org.ops4j.pax.web.ssl.password=xxx
org.ops4j.pax.web.ssl.keypassword=xxx
org.osgi.service.http.port.secure=443

but how can I See them from the config editor?
Also, I'm not completely sure on where is right to put those
properties, for example the HTTPS config, as for,
http://wiki.ops4j.org/display/paxweb/SSL+Configuration

the file where to write is not specified. It seems to me that
config.properties works, but I think that all the properties files
under etc are read, right? So there's some kind of hierarchy? Where's
that explained? In fact I can't be sure if it works. Example, if a
serve answer correctly at

http://domain:8181/app/signin

should it also answer at

https://domain/app/signin

Cause in my situation, it does not.

Also, talking about ports, I've tried to change 8181 into 80 but my
http bundles now does not answer neither on 80 or 8181. Maybe is a
firewall problem but it's a practice you recommend? I mean, I do want
http on 80, and I do not want to put some apache proxy behind Karaf,
so I can't figure out any other way than changing the http service
port there, is correct?

Finally, do you recommend me a book on Karaf? I already had OSGi in
Action but maybe Karaf in action (or such)  can be good for me.


Thanks for any support.

Danielle,

If you'd like to see the contents of a configuration file deployed into
Karaf (assuming it has a .cfg extension), you would do the following (lets
say you want to see the contents of org.apache.karaf.log.cfg) :

1)  features:install config
2) config:list '(service.id=org.apache.karaf.log)'

Note that the.cfg extension is omitted.

I second Achim.

Just an information. From a general point of view, Karaf configuration 
is powered by OSGi ConfigAdmin.

In ConfigAdmin, the configurations are defined as a set of properties 
group by a ID (PID).

For instance, org.ops4j.pax.web is a ID containing properties relative 
to Pax Web.
It allows a better overview of properties by bundles/applications.

JB

Re: configuring karaf dynamically

Posted by Daniele Dellafiore <da...@dellafiore.net>.

Thanks.
I moved the config to the new file and now I see the config line with a

config:list |grep 443

Still, I've refreshed org.eclipse.jetty.http bundle, also restarted it
and my http application bundle, even restarted the whole karaf (!) but
yet the https does not answer.

I'm thinking issue is outside karaf cause if I move jetty HTTP port to
80, it does no answer as well...

Anyway thanks for precious tips, now I can dynamically change
properties and that's good.
So for any bundle of mine, a .cfg file in etc will make me able to use
dynamic config for it?
