Inspr Controller dApp Example

Description

This folder contains the files necessary to run the controller dApp example in your cluster. This examples consists in the creation of a dApp in Insprd that can do the following:

1. Create a new dApp called controllerprimes in the root. This dApp is the same as the one defined in examples/primes (generates numbers and prints the ones that are primes).
2. Delete the dApp controllerprimes.
3. Update the dApp controllerprimes adding a new Annotation to it.

Each of the previous can be done by making a request to the controller dApp. A request can be made by using curl:

curl inspr.com/<create | update | delete>

How to run it:

Make sure the latest Inspr CLI version is installed.

• To get the latest version, run the following command:
  go install inspr.dev/inspr/cmd/inspr

Before running the Inspr CLI command to create the app in your cluster be sure to set the configuration beforehand.
Also, this example uses Kafka as the Channels Message Broker (for controllerprimes dApp), so it must be first installed in the cluster, and then you must install it on Insprd.

You can install Kafka in Insprd running the following command from within /examples/controller folder: insprctl cluster config kafka yamls/kafka.yaml.

Now that everything is set and ready, run the following to create the Controller dApp:

insprctl apply -f yamls/dapp.yaml

Once that is done, you want to get the name of the Service that was created in your Kubernetes Cluster and place it in the ingress.yaml file in /yamls, in all the paths.

- path: /<create | update | delete>
    pathType: Prefix
    backend:
        service:
        name: <SERVICE_NAME>
        port:
            number: 8080

Then the ingress for the Controller dApp can be applied in the cluster:

k apply -f yamls/ingress.yaml --namespace inspr-apps

Now everything is set! You can now make the requests to the Controller dApp so it creates/updates/deletes the controllerprimes dApp!
