Description
Open5GS: MongoDB crashes on RPi CM4 in Docker build due to unsupported ARM64 instructions
Description
When running the Docker build of Open5GS on a Raspberry Pi Compute Module 4 (RPi CM4), MongoDB crashes immediately.
waiting for mongodb
./open5gs_entrypoint.sh: line 26: 77 Illegal instruction (core dumped) mongod --logpath /tmp/mongodb.log
The root cause is that the official MongoDB ARM64 build uses CPU instructions not supported by the ARM Cortex-A72 (ARMv8-A) processor used in RPi CM4.
Steps to Reproduce
- Go to the directory with srsRAN_Project
- Build and run Open5GS in Docker on a RPi CM4 (arm64):
cd ./docker/open5gs
docker network create --subnet=10.53.1.0/24 open5gsnet
docker build --target open5gs -t open5gs-docker .- Start MongoDB container:
docker run --net open5gsnet --ip 10.53.1.2 --env-file open5gs.env --privileged --publish 9999:9999 open5gs-docker ./build/tests/app/5gc -c open5gs-5gc.yml- Observe immediate crash:
waiting for mongodb
./open5gs_entrypoint.sh: line 26: 77 Illegal instruction (core dumped) mongod --logpath /tmp/mongodb.logObserved Behavior
- MongoDB process crashes on startup.
- Backtrace shows
illegal instruction. - Confirmed that the crash is due to unsupported ARMv8 instructions in the official MongoDB ARM64 binaries.
Expected Behavior
MongoDB should run normally on RPi CM4 inside the Docker environment.
Workaround / Fix
The issue was resolved by installing MongoDB from an unofficial repository that provides binaries compatible with Raspberry Pi CM4.
Below is a patch to the Dockerfile showing the change:

Suggestion
- Document this incompatibility for ARM64 users (RPi CM4 and similar)
- Optionally provide an alternative Dockerfile that pulls a MongoDB build compatible with RPi CM4
