deploy a FIWARE context broker on OpenShift Local and AgriGreenhouse Smart Model Data apps

Your mission, should you choose to accept it, is to deploy a FIWARE context broker on OpenShift Local and AgriGreenhouse Smart Model Data apps.

Walk through Youtube videos related to your task

These Youtube videos have been carefully prepared to help you with this data import task:

• Installing OpenShift Local for doing cloud computing on your personal computer!
• Install a Hashicorp Vault on OpenShift Local to easily secure your GitOps
• Configure Vault token, policy, auth method, role, and secret to secure your GitOps
• Install ArgoCD on Openshift Local to monitor the state of your GitOps and Applications
• Setup External Secret linked to Vault in OpenShift Local to keep your application passwords secure
• Deploy ArgoCD Apps to OpenShift Local like MongoDB and the Orion LD Context Broker

More details about your task

• Deploy the Orion LD Context Broker provided by FIWARE using these instructions.
• Help your other team members who also wish to deploy the Orion LD Context Broker on their own OpenShift Local environment.
• Work with your data specialist to import your AgriGreenhouse data into the FIWARE Context Broker running in your OpenShift Local environment.
• Work with your visualization specialist to deploy visualization tools to your OpenShift Local environment.
• Work with your documentation specialist to document the deployment of the OpenShift Local environment, the AgriGreenhouse data, and the visualization tools.
• If you are not sure what kind of applications you could deploy to gather AgriGreenhouse data, you may want to use your imagination. Imagine if there was a AgriGreenhouse sensor in your actual city, or a AgriGreenhouse sensor in a small scale toy city that you could simulate. What kind of sensors could you use? How would you design such a simulation in an actual city or a toy city? How would you visualize AgriGreenhouse data in an actual city or a toy city?
• To the orion-ld Deployment in the fiware namespace, I suggest adding an Environment Variable ORIONLD_CORS_ALLOWED_ORIGIN to __ALL so that the visualization specialist's application will be able to make requests to the Context Broker using JavaScript and AJAX.

The day of the operation is Thursday February 2nd, 2023

You will have 4 hours to complete your mission.

Work with Smart Data Models and the FIWARE Context broker in Europe

At the end of the day

Should you, or any of your force be taken or compromised that day, you must report back as many changes as you have made, and any knowledge of your actions, by pull request or comments on the issue on the board.
