Subject Re: Levels of Containerization - focus on Docker and Karaf
Date Thu, 12 Jan 2017 10:55:24 GMT
Fwiw, starting with Karaf 4.x, you can build custom distributions which are
mostly static, and that more closely map to micro-services / docker
images.  The "static" images are called this way because you they kinda
remove all the OSGi dynamism, i.e. no feature service, no deploy folder,
read-only config admin, all bundles being installed at startup time from
etc/startup.properties.
This can be easily done by using the karaf maven plugin and configuring
startupFeatures and referencing the static kar, as shown in:
