Requirements

The setup is based on the following requirements:

  • Install Docker version 1.10.0+

  • Install Docker Compose version 1.6.0+

  • Clone this Repository:

    git clone https://github.com/i-Asset/distribution-network.git
cd distribution-network
git checkout staging

Setup

Setup Messaging Layer

Apache Kafka is used as Core delivery framework. The easiest way to set up a Kafka cluster, is with Docker Compose.

docker-compose -f setup/kafka/docker-compose.yml up --build -d
docker-compose -f setup/kafka/docker-compose.yml ps  # for stati of the services
docker-compose -f setup/kafka/docker-compose.yml logs -f  # for continuous logs
docker-compose -f setup/kafka/docker-compose.yml down  # shut down the cluster, remove data with -v flag

To test the Kafka setup, list, create and delete topics, Kafka binaries are required (see the next subsection (optional) Install Kafka binaries for that). For information to set up a Kafka cluster on multiple nodes without Docker (which is suggested) for production, check this guide.

(optional) Install Kafka binaries

This step is only required for developing the Distribution Network, because the service is run on the host. For the productive mode, the service runs within a Docker container and therefore doesn't need Kafka binaries on the host. It is also important to note, that it is hard to install Kafka on Windows.

The following lines installs Kafka version 2.7 locally in the directory /kafka:

sudo apt-get update
sh setup/kafka/install-kafka.sh
sh setup/kafka/install-kafka-libs.sh

With the Kafka binaries topics can be listed, created and deleted. Moreover, messages can be produced and consumed.

/kafka/bin/kafka-topics.sh --zookeeper :2181 --list
/kafka/bin/kafka-topics.sh --zookeeper :2181 --create --topic test_single --replication-factor 1 --partitions 1
/kafka/bin/kafka-topics.sh --zookeeper :2181 --create --topic test --replication-factor 3 --partitions 3 --config cleanup.policy=compact --config retention.ms=3628800000 --config retention.bytes=-1
/kafka/bin/kafka-topics.sh --zookeeper :2181 --delete --topic test_single
/kafka/bin/kafka-topics.sh --zookeeper :2181 --list

/kafka/bin/kafka-console-producer.sh --broker-list :9092 --topic test
>Hello Kafka
> [Ctrl]+C
/kafka/bin/kafka-console-consumer.sh --bootstrap-server :9092 --topic test --from-beginning
Hello Kafka

Setup Database

PostgreSQL is used as relational database for static data within the Distribution Network.

Option 1: Docker

The easiest way to setup PostgreSQL is via Docker Compose:

docker-compose -f setup/postgresql/docker-compose.yml up --build -d
docker-compose -f setup/postgresql/docker-compose.yml ps  # status of postgres
docker-compose -f setup/postgresql/docker-compose.yml logs -f  # for continuous logs
docker-compose -f setup/postgresql/docker-compose.yml down  # shut down, remove data with -v flag

Option 2: On the Host

As an alternative, e.g., one can also setup postgreSQL directly on the host. There are various instructions on how to install postgres, this one works for Ubuntu 20.04:

sudo apt install libpq-dev
sudo sh -c 'echo "deb http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'
wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
sudo apt-get update
sudo apt-get install postgresql

sudo -u postgres psql -c "CREATE ROLE postgres LOGIN PASSWORD 'postgres';"
sudo -u postgres psql -c "CREATE DATABASE distributionnetworkdb OWNER postgres;"
sudo -u postgres psql -f setup/postgresql/initdb/db_init.sql

Create Database

The database distributionnetworkdb is created and filled with demo-data automatically with the startup, as configured in setup/postgresql/initdb/db_init.sql. Check the entries in the tables using commands like:

docker exec -it postgresql_postgresdb_1 psql -U postgres -d distributionnetworkdb -c "select * from users;"

Note that dummy users and companies have negative ids, real entries have always non-negative entries.

Setup Distribution Service

The Distribution Service depends can be set up either on the host (preferred for development) or within a Docker container (easier to set up). Select the appropriate option below.

In both cases, the Distribution Service depends on the Delivery Framework Apache Kafka and the Database Postgres. The respective dependency-variables have to be valid and are required to set up the Distribution Service.

Option 1: Setup Distribution Service on Docker

Make sure postgres is available on port 5432 and postgres is the owner of the database distributionnetworkdb.

docker-compose -f /server/postgresql/docker-compose.yml up --build -d

Then set the environment variable DOCKER_HOST_IP and start the main docker compose:

export DOCKER_HOST_IP=$(hostname -I | cut -d ' ' -f1)
echo $DOCKER_HOST_IP
docker-compose up --build -d

Check if everything works using:

docker ps
docker-compose logs -f
docker-compose logs -f distribution-network
docker inspect distribution-network_distribution-network_1

Option 2: Setup Distribution Service on Host

Make sure to start a new virtual env for this setup! Then, install the python modules via:

virtualenv --python=/path/to/python /path/to/new/venv
source /path/to/new/venv/bin/activate  # e.g. /home/chris/anaconda3/envs/venv_iot4cps/bin/activate
pip install -r setup/requirements.txt

Additionally, a running Kafka instance is required, e.g.:

export DOCKER_HOST_IP=$(hostname -I | cut -d ' ' -f1)
echo $DOCKER_HOST_IP
docker-compose -f /server/kafka/docker-compose.yml up --build -d

Make sure that the file server/.env directs to the correct configuration set, that is either development, production, docker or platform-only (that doesn't interact with the Kafka data streaming). The platform can be started by running:

export FLASK_APP=$(pwd)/server/app.py
echo $FLASK_APP
python -m flask run --host $(hostname -I | cut -d " " -f1) --port 1908

Usage

Platform UI

One easy way to check the platform is via the light-weight user interface that comes with the distribution-network:

platform_ui

RestAPI

The RestAPI is the preferred user interface and is documented in swagger on server/distributionnetwork/swagger-ui.html.

swagger_ui

Distribution Network - Connection Tester

Execute without parameters and authorization.

System Requests

Creates the specified system with dependencies and Kafka Topics. Requires that the user and company exist. In contrast to POST, the PUT method allows an edit of the system.
