Krossboard Kubernetes Operator provides custom resources (CR) along with an operator to deploy and manage instances of Krossboard as Kubernetes pods.

The Krossboard CR defines a Krossboard instance as a Kind, as well as parameters to bootstrap that instance: krossboard-api, krossboard-ui, krossboard-consolidator, krossboard-kubeconfig-handler, kube-opex-analytics instances.

Each instance of Krossboard enables to track the usage of a set of Kubernetes clusters listed in a KUBECONFIG secret.

The next steps describe how to deploy the operator and a Krossboard instance.

The following command deploy the latest version of Krossboard Operator.

kubectl apply -f https://raw.githubusercontent.com/2-alchemists/krossboard-kubernetes-operator/main/config/releases/latest/krossboard/krossboard-kubernetes-operator.yaml

The installation is achieved in a namespace named krossboard.

Once the operator deployed, a custom resource named Krossboard is created. This CR is used to define each instance of Krossboard.

See krossboard.yaml for an example of Krossboard instance

apiVersion: krossboard.krossboard.app/v1alpha1
kind: Krossboard
metadata:
  name: krossboard
spec:
  koaImage: rchakode/kube-opex-analytics:22.12.0
  krossboardDataProcessorImage: krossboard/krossboard-data-processor:1.3.0
  krossboardUIImage: krossboard/krossboard-ui:1.2.0-49b2666
  krossboardPersistentVolumeClaim: krossboard-data-pvc
  krossboardSecretName: krossboard-secrets

Each instance of Krossboard allows to track the usage of a set of Kubernetes clusters listed in a KUBECONFIG secret.

• The secret name is set by the parameter krossboardSecretName (default is krossboard-secrets).
• The secret key is kubeconfig.

Given a KUBECONFIG resource (/path/to/kubeconfig in the below command), you can create a secret for Krossboard Operator as follows.

kubectl -n krossboard \
    create secret --type=Opaque generic krossboard-secrets \
    --from-file=kubeconfig=/path/to/kubeconfig

The below command deploys an instance of Krossboard based on the latest version.

kubectl -n krossboard apply -f https://raw.githubusercontent.com/2-alchemists/krossboard-kubernetes-operator/main/config/releases/latest/krossboard/krossboard-deployment.yaml

Once started, the instance enables access to two Kubernetes services:

• krossboard-ui.krossboard.svc enabling access to Krossboard UI.
• krossboard-api.krossboard.svc enabling access to Krossboard REST API.

• https://krossboard.app/
• Krossboard Enterprise Support
