Using Sling Launchpad for production

Question

I was trying to understand deployment scenarios for Sling/JCR when I started wondering if I could simply use the Sling Launchpad and simply start the server using the jar. My project needs simplicity more than performance, but is there something seriously wrong with this approach? Alternatively, is there a good place where Sling/JCR deployment is discussed in detail?

Answer 1

I don't think we have a detailed description on how to deploy Sling applications, the best might be to ask on the users mailing list ( http://sling.apache.org/site/project-information.html#ProjectInformation-lists ) so that others can share their experiences.

As for starting with the launchpad I don't see a problem with that, that's pretty much how we are using Sling in Adobe CQ5. We have our own customized launcher that adds a few features, mostly related to upgrades management, but the basics are the same.

Although the few details of your project, I can say that Sling-Launchpad is a very useful tool to start an OSGi environment with selectable bundles. You just make a list of bundles to be included in the environment. It is very actively used in Apache Stanbol project. For the details you can investigate the various launchers of Stanbol e.g full, full-war, etc. Those launchers produce a single jar file including the necessary files to start the server.

Cryo-answer, maybe better late than never. As long as you're not after a clustered config, the sling trunk build now has a debian contrib module that packages the launchpad jar in a debian package. It's a simplistic packaging mechanism that doesn't fully exploit all possible use cases, but it does setup logging and provide an etc/defaults for for config setup.
