Knative Source - MongoDB

The MongoDb Event source adds support of MongoDb resources to Knative Eventing.

Prerequisites

1. Install Knative Eventing in your Kubernetes Cluster.

2. Either:

   • Install MongoDb on your Kubernetes Cluster and create a Replica Set. Instructions available here.

   • Create a MongoDb Cluster on Atlas, through GCP for example. Link available here.

3. Install ko and then execute:

   ko apply -f ./config
   

Usage

1. Create a secret containing the data needed to access your MongoDb service. For example:

    apiVersion: v1
    kind: Secret
    metadata:
        name: my-mongo-secret
        namespace: default
    stringData:
            URI: mongodb://USERNAME:PASSWORD@IP:PORT/USERDB

   The URI is the connection string of your Mongo Database or Cluster. USERDB is the database your user account pertains to (can be admin).

2. Create the MongoDbSource custom object, by configuring the required database has to be provided, but collection is optional. For example, with a Knative Service as a sink:

    apiVersion: sources.google.com/v1alpha1
    kind: MongoDbSource
    metadata:
        name: mongodb-example-source
        namespace: default
    spec:
        database: db1
        collection: coll1  # optional
        secret:
            name: my-mongo-secret
    sink:
        ref:
          apiVersion: serving.knative.dev/v1
          kind: Service
          name: event-display
          namespace: mongodb
