Description

This project represents a simulation, where sensors send data to a controller, which makes a decision based on the data and sends it to the manipulator. The controller also provides a HTTPS API, so that a 3rd-party servers can access the decisions made by the controller.

Important!

The project makes use of submodules.

Pull them manually after clonning the repository, by running the following commands:

git submodule init
git submodule update

Or add --recurse-submodules to the git clone (this option will clone all submodules recursively, so the size of the resulting cloned repository might be big).

Running the app

Dependencies:

• POCO
• OpenSSL and/or libssl-dev

If one runs the system in the docker, there is no need to bother with the dependencies.

Docker

Docker-compose

Run the simulation using docker-compose:

cd docker
docker-compose up --scale sensor=8

This command will run the simulation via docker-compose with 8 sensors.

One will be able to observe the console output of both a manipulator and a controller in the logs. In addition a flask application is available at 127.0.0.1:5000 to send requests to the controller to retrieve its decisions.

To build all necessary images, one can first run dcoker-compose build or specify --build option in addition to dcoker-compose up.

Building an image

Example of building a docker image:

cd docker
docker build -t sensor:test -f builtCppPoco.Dockerfile --build-arg APP_NAME=sensor ..

This script will build an image with the sensor app.

When building an image for the first time it might take some time, as it needs to build a Poco library first. Once the stage of building Poco has passed, docker will use its cache to build images with other apps faster.
