The instructions at

.md

have allowed us to install the OCB and mongoDB on a raspbery pi 4, although we have had to modify the suggested docker-compose.yml file as follows:

• It says that version: "3" is "obsolete"
• The mongo:6.0 image is not available for the ARM processor of the RP4. If we use mongo:4.4.18, which is the latest version supported for the RP4 ARM processor, it works. We are using docker 27.3.1 version.

We have found some issues when updating the RP4 software. We believe the issue is with mongoDB and its support for the ARM processor on the RP4 that is ARMv8-A, but we have the following warning (note we are using mongo:4.4.18, other versions are not RP4 compatible):

mongo-1 | WARNING: MongoDB 5.0+ requires ARMv8.2-A or higher, and your current system does not appear to implement any of the common features for that!

Are there known issues with mongo versions? Is it possible to use higher versions of mongo in RP4?

We also have to use other generic enablers, like quantumleap, cygnus, crateDB, and IoTAgents. Is it possible to include its installation in the tutorial in

.md

Thanks in advance.
