Local Setup

Build databroker-perf binary

cargo build --release

Start databroker (Docker)

docker run -it --rm -p 55555:55555 ghcr.io/eclipse-kuksa/kuksa-databroker:main --insecure --enable-databroker-v1

If running on MacOS:

docker run -it --rm -p 55556:55556 ghcr.io/eclipse-kuksa/kuksa-databroker:main --insecure --enable-databroker-v1 --port 55556

Start databroker (Binary)

Use binary from kuksa-databroker repository

cargo build --release

./target/release/databroker --vss data/vss-core/vss_release_4.0.json --enable-databroker-v1

If running on MacOS:

./target/release/databroker --vss data/vss-core/vss_release_4.0.json --enable-databroker-v1 --port 55556
