Is there any possibility of running Orion ContextBroker on Raspberry Pi with Raspbian OS?
The requirements recommended in the Orion documentation are:
Although we haven't done yet a precise profiling on Orion Context Broker, tests done in our development and testing environment show that a host with 2 CPU cores and 4 GB RAM is fine to run the ContextBroker and MongoDB server. In fact, this is a rather conservative estimation, Orion Context Broker could run fine also in systems with a lower resources profile. The critical resource here is RAM memory, as MongoDB performance is related to the amount of available RAM to map database files into memory.
Besides the board constrained resources, you will have to search about the equivalent required libraries for RaspbianOS.
There is a discussion about it here: https://github.com/telefonicaid/fiware-orion/issues/15
