Installation

The easiest way to install it is by using the helm chart.

helm upgrade --install axonops-developer-operator --create-namespace -n axonops charts/axonops-developer-operator

Usage

The simplest configuration would be the following to deploy a single Cassandra node with the AxonOps components:

apiVersion: axonops.com/v1beta1
kind: AxonOpsCassandra
metadata:
  name: axonopscassandra-sample
  namespace: axonops-dev
spec:

By default it does not use persistent storage but this is configurable.

apiVersion: axonops.com/v1beta1
kind: AxonOpsCassandra
metadata:
  name: axonopscassandra-sample
  namespace: axonops-dev
spec:
  cassandra:
    replicas: 3
    clusterName: "my-dev-env"
    image:
      tag: "5.0"
    persistentVolume:
      size: 2Gi
      storageClass: local-path
  axonops:
    elasticsearch:
      persistentVolume:
        size: 2Gi
        storageClass: local-path

We only support three Apache Cassandra major releases: 4.0, 4.1 and 5.0 (see image.tag above).

Accessing the AxonOps Dashboard

Port Forwarding

This operator is meant for developer that would like to test and use an Apache Cassandra cluster locally or in a shared Kubernetes environment. If you're running locally most likely you cannot use a Load Balancer and therefore you're only option to access the AxonOps Dashboard is via kube-proxy.

kubectl -n axonops-dev port-forward svc/ds-axonopscassandra-sample 3000:300

or

kubectl port-forward -n axonops-dev $(kubectl get svc -n axonops-dev -l component=dashboard -oname) 3000:3000

Ingress

If you do have an ingress, you can enable it:

apiVersion: axonops.com/v1beta1
kind: AxonOpsCassandra
metadata:
  name: axonopscassandra-sample
  namespace: axonops-dev
spec:
  axonops:
    dashboard:
      ingress:
        enabled: true
        ingressClassName: nginx
        labels:
          hello: world
        annotations: {}
        hosts:
          - axonops-dev.mydomain.com
