CEPTA - Complex Event Processing Transportation Analysis

The open-source CEPTA project aims to examine the applicability of modern (complex) event processing techniques in the context of intermodal transportation. The project is under active development and will regularly push updates to the demo instance.

For more information, see bptlab.github.io/cepta/.

Building

To build all executables of the entire project:

bazel build //:cepta

To build only a specific module or executable:

bazel build //auxiliary/producers/replayer  # Example

Running

To run a specific executable:

bazel run //auxiliary/producers/replayer -- --port 8080  # Example

To run mutiple specific executables (prevents locking) use run.sh instead of bazel run:

./run.sh //auxiliary/producers/replayer -- --port 8080  # Example

Testing

bazel test :all
bazel test //core:core-tests  # Only test core

Deployment

The project uses docker and docker-compose for deployment. For instructions see docs/deployment/dev.md or docs/deployment/prod.md respectively.

Summary: To run the latest version, run

CEPTA_VERSION="v0.5.0" docker-compose -f deployment/prod/docker-compose.yml up

To run specific containers (single or multiple) run:

./deployment/dev/devenv.sh up args...

The containers that can be used as args can be found in /deployment/dev/compose for example: envoy

Have you never build the docker images before than run following instead:

BUILD=1 ./deployment/dev/devenv.sh up args...

Deployment on Mac

Seeing an error like this while starting the docker container:
standard_init_linux.go:211: exec user process caused "exec format error"

MacOs needs a slight configuration to the build stage. The docker images that are build with bazel have to be build for linux to run in the docker environment. Therefore you have to build the images like this:

bazel run //osiris/usermgmt:build-image --platforms=@io_bazel_rules_go//go/toolchain:linux_amd64
