How to SSL enable the ServiceMix web console?

ServiceMix 4 comes with a useful web console. It needs to be installed manually; it is not deployed out of the box:

karaf@root> features:install webconsole

... and thereafter the console can be accessed using URL:
http://localhost:8181/system/console/bundles
(applies to 4.3.1, URL might differ on other versions of SMX).

In order to secure the console to use HTTPS, it is necessary to create a file

$KARAF_HOME/etc/org.ops4j.pax.web.cfg

and configure it using any of the property keywords defined in this WebContainerConstants class.

Here is a possible example:

# configures the SMX Web Console to use SSL
#
# @SeeAlso: https://github.com/ops4j/org.ops4j.pax.web/blob/master/pax-web-api/src/main/java/org/ops4j/pax/web/service/WebContainerConstants.java
# for possible configuration properties

org.osgi.service.http.enabled=false
org.osgi.service.http.port=8181

org.osgi.service.http.secure.enabled=true
org.osgi.service.http.port.secure=8183

org.ops4j.pax.web.ssl.keystore=/path/to/keystore.ks
org.ops4j.pax.web.ssl.keystore.type=JKS
org.ops4j.pax.web.ssl.password=blah
org.ops4j.pax.web.ssl.keypassword=bluh
org.ops4j.pax.web.ssl.clientauthwanted=false
org.ops4j.pax.web.ssl.clientauthneeded=false

Make sure to access the web console using https:// after applying this configuration.
