\n\n# Dragonfly Operator Helm Chart\n\nDragonfly Operator manages the lifecycle of DragonflyDB instances on Kubernetes, providing automated provisioning, failover, scaling, and management of in-memory datastores. The Dragonfly Operator Helm chart automates deployment and configuration of the DragonflyDB Operator in Kubernetes clusters using the Minimus Dragonfly Operator images.\n\n \n## {{icon-list-search}} Prerequisites\n\n- A subscription to the Minimus images included in the chart\n- A running Kubernetes cluster (v1.21 or higher is recommended)\n- `kubectl` installed and configured\n- Helm v3.8 or higher for OCI support ([Installation instructions](https://helm.sh/docs/intro/install/))\n- Cluster Admin privileges\n\n**Note**: The Dragonfly Operator requires CRDs to be installed in the cluster. The chart installs them automatically by default (`crds.install: true`).\n\n

\n\n## {{icon-rocket}}Try It Out\n\nIn this example we will deploy the DragonflyDB Operator on a Kubernetes cluster using the Minimus Dragonfly Operator Helm chart. The operator will be ready to manage DragonflyDB instances.\n\n

\n\n### Step 1: Start Cluster\n\n

\n\nIf you have a cluster to work with, skip this step. Otherwise, start a Minikube cluster. [Deployment instructions](https://minikube.sigs.k8s.io/docs/start/?arch=%2Flinux%2Fx86-64%2Fstable%2Fbinary+download)\n\n

\n\n### Step 2: Create Namespace\n\n

\n\nCreate a namespace:\n\n```\nkubectl create ns dragonfly-operator\n```\n\n{{if-enterprise}}\n\nNext, create a Kubernetes secret for the Minimus token:\n\n```\nkubectl create secret docker-registry minimus-registry \\\n --docker-server=reg.mini.dev \\\n --docker-username=minimus \\\n --docker-password={{pull-token}} \\\n --namespace=dragonfly-operator\n```\n\n{{/if-enterprise}}\n\n

\n\n### Step 3: Deploy the Helm Chart\n\n

\n\nDeploy the Minimus Helm chart:\n\n```\nhelm install my-dragonfly-operator {{oci-url}} \\\n --version {{chart-version}} \\\n -n dragonfly-operator \\\n --wait\n```\n\nIf you want to override the chart's defaults, go to the Values tab, save a copy locally with your changes. Deploy the chart with your overrides using `-f values.yaml`:\n\n```\nhelm install my-dragonfly-operator {{oci-url}} \\\n --version {{chart-version}} \\\n -f values.yaml \\\n -n dragonfly-operator \\\n --wait\n```\n\n

\n\n### Step 4: Verify Dragonfly Operator is Running\n\n

\n\nConfirm the chart deployed successfully and the operator started:\n\n```\nkubectl get pods -n dragonfly-operator\n```\n\nYou should see output similar to:\n\n```\nNAME READY STATUS RESTARTS AGE\nmy-dragonfly-operator-dragonfly-operator-xxxxxxxxx-xxxxx 2/2 Running 0 2m\n```\n\nThe pod should show 2/2 containers ready for the operator manager and the kube-rbac-proxy sidecar.\n\n

\n\n### Step 5: Create a DragonflyDB Instance\n\n

\n\nNow that the operator is running, you can create a DragonflyDB instance managed by it.\n\nSave the following custom resource to a file called `dragonfly-sample.yaml`:\n\n```yaml\napiVersion: dragonflydb.io/v1alpha1\nkind: Dragonfly\nmetadata:\n name: dragonfly-sample\n namespace: dragonfly-operator\nspec:\n replicas: 2\n resources:\n requests:\n cpu: 500m\n memory: 500Mi\n limits:\n cpu: 600m\n memory: 750Mi\n```\n\nApply it to the cluster:\n\n```\nkubectl apply -f dragonfly-sample.yaml\n```\n\nWait for the instance to become ready, then verify its status:\n\n```\nkubectl get dragonflies.dragonflydb.io -n dragonfly-operator\n```\n\n

\n\n### Step 6: Clean Up\n\n

\n\nUninstall the chart and delete the namespace to remove all resources:\n\n```bash\nhelm uninstall my-dragonfly-operator -n dragonfly-operator\nkubectl delete namespace dragonfly-operator\n```\n\n
