Simple nodejs express application for use with the FIWARE Step-by-Step tutorials. 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.

This application provides various sources of context and demonstrates various aspects of FIWARE To run the application in debug mode add DEBUG=tutorial:*

• WEB_APP_PORT=3000 # Port used by the content provider proxy and web-app for viewing
• CONTEXT_BROKER=http://orion:1026/v2 - URL of the context broker to update context
• NGSI_LD_PREFIX= - Whether to use full URNs for devices
• SECURE_ENDPOINTS=true - Enable Keyrock as PDP - default is false

• IOTA_HTTP_HOST=iot-agent - The URL of the IoT Agent
• IOTA_HTTP_PORT=7896 - Port used by the dummy IoT devices to commuicate with the IoT Agent
• DUMMY_DEVICES_PORT=3001 - Port used by the dummy IoT devices to receive commands
• DUMMY_DEVICES_TRANSPORT=HTTP - Default transport used by dummy IoT devices (either HTTP or MQTT)
• DUMMY_DEVICES_API_KEY=4jggokgpepnvsb2uv4s40d59ov - Device API Key.

• KEYROCK_URL=http://localhost - URL for Keyrock IDM
• KEYROCK_IP_ADDRESS=http://172.18.1.5 - IP address for Keyrock IDM
• KEYROCK_PORT=3005 - Port that Keyrock is listening on
• KEYROCK_CLIENT_ID=tutorial-dckr-site-0000-xpresswebapp - Client ID for the appliction within keyrock
• KEYROCK_CLIENT_SECRET=tutorial-dckr-site-0000-clientsecret - Client secret for the appliction within keyrock

• AUTHZFORCE_URL=http://authzforce - URL for Authzforce
• AUTHZFORCE_PORT=8080 - Port that Authzforce is listening on

The Dockerfile associated with this image can be used to build an image in several ways:

• By default, the Dockerfile retrieves the latest version of the codebase direct from GitHub (the build-arg is optional):

docker build -t fiware/tutorials.Step-by-Step . --build-arg DOWNLOAD=latest

• You can alter this to obtain the last stable release run this Dockerfile with the build argument DOWNLOAD=stable

docker build -t fiware/tutorials.Step-by-Step . --build-arg DOWNLOAD=stable

• You can also download a specific release by running this Dockerfile with the build argument DOWNLOAD=<version>

docker build -t fiware/tutorials.Step-by-Step . --build-arg DOWNLOAD=1.7.0

• To download code from your own fork of the GitHub repository add the GITHUB_ACCOUNT and GITHUB_REPOSITORY arguments to the docker build command.

docker build -t fiware/tutorials.Step-by-Step . --build-arg GITHUB_ACCOUNT=<your account> --build-arg GITHUB_REPOSITORY=<your repo>

Alternatively, if you want to build directly from your own sources, please copy the existing Dockerfile into file the root of the repository and amend it to copy over your local source using :

COPY context-provider /usr/src/app

Full instructions can be found within the Dockerfile itself.
