Apache Karaf is a good platform for deploying OSGi based applications. Karaf is also a good platform for testing and debugging these applications. This article describes how to test and debug OSGi bundles and OSGi applications with karaf and eclipse. Continue reading Develop OSGi applications using karaf→
Note! This is an improvement over the packaging in Installing apache karaf on debian stretch, this package is packaged using native debian packaging tools instead of fpm, and is built from the karaf source tarball instead of the karaf binary tarball.
Apache karaf is an OSGi container and application server that is provisioned from maven, and has an ssh server. Basically it is possible to start an empty karaf, ssh in and give some commands to install an application using maven.

I don’t know if the cause was excessive logging, the use of ntopng (which did write quite a lot, both in the number of files, the number of files, and in the total storage used, which was approximately 0,5GB after 30 days of uptime) or simply a bad sd card.
However, going forward with a new sd card, I’ve done the following:
Put /var/log on tmpfs (limited to 100MB in size), synced to a backing store on the sd card using rsync
