weka-operator

Kubernetes operator for managing WEKA clusters on Kubernetes.

Overview

The weka-operator automates the deployment and management of WEKA distributed storage clusters on Kubernetes. It provides:

• Automated WEKA cluster provisioning and lifecycle management
• Node discovery and container orchestration
• Drive management and cluster scaling
• CSI driver integration for persistent volumes

Prerequisites

• Kubernetes cluster (v1.26+)
• Helm 3.x
• Container registry access (Quay.io or your own registry)
• WEKA license and credentials

Installation

Set image pull secret name if needed

export QUAY_USERNAME=<quay username>
export QUAY_PASSWORD=<quay password>

kubectl create namespace weka-operator-system
kubectl create secret docker-registry quay-io-robot-secret \
  --docker-server=quay.io \
  --docker-username=$QUAY_USERNAME \
  --docker-password=$QUAY_PASSWORD \
  --docker-email=$QUAY_USERNAME \
  --namespace=weka-operator-system # operator will be scheduling some containers in own namespace

kubectl create secret docker-registry quay-io-robot-secret \
  --docker-server=quay.io \
  --docker-username=$QUAY_USERNAME \
  --docker-password=$QUAY_PASSWORD \
  --docker-email=$QUAY_USERNAME \
  --namespace=default # wekacluster/wekaclient namespaces, that can be different from operator itself, each namespace needs a copy of secret

# Install CRDs using server-side apply
helm show crds oci://quay.io/weka.io/helm/weka-operator --version v1.9.1 | \
  kubectl apply --server-side -f -

# Install operator
helm upgrade --install weka-operator oci://quay.io/weka.io/helm/weka-operator \
  --namespace weka-operator-system \
  --create-namespace --version v1.9.1

See values for all configuration options.

Dev flows

Building and pushing weka-operator image and helm with docker only

helm registry login quay.io -p xxx -u xxx \
  && docker login quay.io -p xxx -u xxx \
  && VERSION=1.11.0-$USER-dev.0 REPO=quay.io/weka.io/weka-operator-dev HELM_REPO=quay.io/weka.io/helm-dev"\ 
   ./build-release.sh

installing dev release using helm

export REPO=quay.io/weka.io/weka-operator-dev 
export HELM_REPO=quay.io/weka.io/helm-dev
export VERSION=v1.11.0-$USER-dev.0; helm show crds oci://$HELM_REPO/weka-operator --version $VERSION | kubectl apply --server-side -f -
helm upgrade \
--install weka-operator oci://$HELM_REPO/weka-operator \
--namespace weka-operator-system \
--create-namespace --version $VERSION --set image.repository=$REPO

Building, pushing and deploying Using Dagger, a quick dev flow supporting remote building

See dagger for deploying the operator with Dagger.

Unit Tests

go test ./...

Examples

See doc/examples for YAML configurations including clusters, clients, drive sharing, and policies.

API

The operator api is defined in a separate api repository.
Any changes to the api requires updating the api submodule.
