This is a collection of tutorials for the FIWARE system. Each tutorial consists of a series of exercises to demonstrate the correct use of individual FIWARE components and shows the flow of context data within a simple Smart Solution either by connecting to a series of dummy IoT devices or manipulating the context directly or programmatically.
How to Use
Each tutorial is a self contained learning exercise designed to teach the developer about a single aspect of FIWARE. A summary of the goal of the tutorial can be found in the description at the head of each page. Every tutorial is associated with a GitHub repository holding the configuration files needed to run the examples. Most of the tutorials build upon concepts or enablers described in previous exercises the to create a complex smart solution which is "powered by FIWARE".
The tutorials are split according to the chapters defined within the FIWARE catalog and are numbered in order of difficulty within each chapter hence the an introduction to a given enabler will occur before the full capabilities of that element are explored in more depth.
It is recommended to start with reading the full Core Context Management: Fundamentals Chapter before moving on to other subjects, as this will give you an fuller understanding of the role of context data in general. However it is not necessary to follow all the subsequent tutorials sequentially - as FIWARE is a modular system, you can choose which enablers are of interest to you.
Docker and Docker Compose
To keep things simple all components will be run using Docker. Docker is a container technology which allows to different components isolated into their respective environments.
- To install Docker on Windows follow the instructions here
- To install Docker on Mac follow the instructions here
- To install Docker on Linux follow the instructions here
Docker Compose is a tool for defining and running multi-container Docker
applications. A series of
*.yaml files are used configure the required
services for the application. This means all container services can be brought
up in a single command. Docker Compose is installed by default as part of Docker
for Windows and Docker for Mac, however Linux users will need to follow the
instructions found here
You can check your current Docker and Docker Compose versions using the following commands:
docker-compose -v docker version
Please ensure that you are using Docker version 18.03 or higher and Docker Compose 1.21 or higher and upgrade if necessary.
Cygwin for Windows
We will start up our services using a simple Bash script. Windows users should download cygwin to provide a command-line functionality similar to a Linux distribution on Windows.
List of Tutorials
Core Context Managment: Fundamentals
These first tutorials are an introduction to the FIWARE Context Broker, and are an essential first step when learning to use FIWARE
Internet of Things, Robots and third-party systems
In order to make a context-based system aware of the state of the real world, it will need to access information from Robots, IoT Sensors or other suppliers of context data such as social media. It is also possible to generate commands from the context broker to alter the state of real-world objects themselves.
Core Context Management: History Management
These tutorials show how to manipulate and store context data so it can be used for further processesing
Persisting Context Data using Apache Flume (MongoDB, MySQL, PostgreSQL)
301. Persisting Context Data using Apache NIFI (MongoDB, MySQL, PostgreSQL)
303. Querying Time Series Data (MongoDB)
304. Querying Time Series Data (Crate-DB)
Security: Identity Management
These tutorials show how to create and administer users within an application, and how to restrict access to assets, by assigning roles and permissions.
Administrating Users and Organizations
402. Managing Roles and Permissions
403. Securing Application Access
404. Securing Microservices with a PEP Proxy
405. XACML Rules-based Permissions
406. Administrating XACML via a PAP
Processing, Analysis and Visualization
These tutorials show how to create, process, analyze or visualize context information
