Frequently Asked Questions


Is it ready?

No, this is a work in progress, but we will be releasing some nightlies soon. We are working at a fast pace developing the platform, but as a work in progress, you should be aware that bugs will be all over the place. Features will be added on a weekly basis, before we enter into the feature freeze phase.

I want to try it anyway. Can I?

Sure!. You will need a server with internet connection and docker installed, and everything else will be taken care of. Be sure to follow the instructions on our github site, and you will get a MongoDB, an Eureka registry and the full marble platform using a single command from the shell.

Where is the documentation?

You can find the documentation in the project's Wiki, and in the main README file of the project.

Is everything developed by you?

Not at all. We are using libraries and software developed by other people, and we will give credit to them appropiately in our third party section (still to be developed). If you think we are using some of your software inappropriately, please let us know.
