Qdrant Quickstart

This guide provides a comprehensive walkabout for deploying and managing Qdrant ReplicaSet Clusters using the KubeBlocks Qdrant Add-on, covering:

System prerequisites and add-on installation
Cluster creation and configuration
Operational management including start/stop procedures
Connection methods and cluster monitoring

Prerequisites

System Requirements

Before proceeding, verify your environment meets these requirements:

A functional Kubernetes cluster (v1.21+ recommended)
kubectl v1.21+ installed and configured with cluster access
Helm installed (installation guide)
KubeBlocks installed (installation guide)

Verify Qdrant Add-on

The Qdrant Add-on is included with KubeBlocks by default. Check its status:

helm list -n kb-system | grep qdrant

Example Output:

NAME                NAMESPACE   REVISION    UPDATED                     STATUS      CHART
kb-addon-qdrant     kb-system   1           2025-05-21                  deployed    qdrant-1.0.0

If the add-on isn't enabled, choose an installation method:


# Add Helm repo
helm repo add kubeblocks-addons https://apecloud.github.io/helm-charts
# For users in Mainland China, if GitHub is inaccessible or slow, use this alternative repo:
#helm repo add kubeblocks-addons https://jihulab.com/api/v4/projects/150246/packages/helm/stable

# Update helm repo
helm repo update
# Search available Add-on versions
helm search repo kubeblocks/qdrant --versions
# Install your desired version (replace <VERSION> with your chosen version)
helm upgrade -i kb-addon-qdrant kubeblocks-addons/qdrant --version <VERSION> -n kb-system


# Add an index (kubeblocks is added by default)
kbcli addon index add kubeblocks https://github.com/apecloud/block-index.git
# Update the index
kbcli addon index update kubeblocks
# Update all indexes
kbcli addon index update --all

To search and install an addon:


# Search Add-on
kbcli addon search qdrant
# Install Add-on with your desired version (replace <VERSION> with your chosen version)
kbcli addon install qdrant --version <VERSION>

Example Output:

ADDON   VERSION         INDEX
qdrant   0.9.0           kubeblocks
qdrant   0.9.1           kubeblocks
qdrant   1.0.0           kubeblocks

To enable or disable an addon:


# Enable Add-on
kbcli addon enable qdrant
# Disable Add-on
kbcli addon disable qdrant

NOTE

Version Compatibility

Always verify that the Qdrant Add-on version matches your KubeBlocks major version to avoid compatibility issues.

Verify Supported Qdrant Versions

List available Qdrant versions:

kubectl get cmpv qdrant

Example Output

NAME     VERSIONS                                STATUS      AGE
qdrant   1.14.0,1.10.0,1.8.4,1.8.1,1.7.3,1.5.0   Available   26d

Check version compatibility for ComponentDefinitions

Step 1. Get the list of ComponentDefinition associated with a given ComponentVersion


kubectl get cmpv qdrant -ojson | jq -r '.metadata.annotations."componentversion.kubeblocks.io/compatible-definitions"' | tr ',' '\n'

Example Output

qdrant-1.0.0

Step 2. Get the list of ComponentDefinition associated with a given ComponentVersion


kubectl get cmpv qdrant -o json | jq -r '.spec.compatibilityRules[] | select(.compDefs | any(startswith("^qdrant"))) | .releases[]'

This returns versions compatible with ComponentDefinition named qdrant:

Example Output

1.5.0
1.7.3
1.8.1
1.8.4
1.10.0
1.14.0

Storage Configuration

Qdrant requires persistent storage. Verify available options:

kubectl get storageclass

Recommended storage characteristics:

Minimum 20Gi capacity
ReadWriteOnce access mode
Supports volume expansion
Appropriate performance for workload

Deploy a Qdrant Cluster

Deploy a basic Qdrant Cluster with default settings:

kubectl apply -f https://raw.githubusercontent.com/apecloud/kubeblocks-addons/refs/heads/main/examples/qdrant/cluster.yaml

This creates:

A Qdrant Cluster with 3 replicas.
Default resource allocations (0.5 CPU, 0.5Gi memory)
20Gi persistent storage

Create a Version-Specific Qdrant Cluster

To create a cluster with a specific version, configure spec.componentSpecs.serviceVersion (major.minor version) fields before applying it:

Verify Cluster Status

When deploying a Qdrant Cluster with 3 replicas:

Confirm successful deployment by checking:

Cluster phase is Running
All pods are operational

Check status using either method:

kubectl get cluster qdrant-cluster -n demo -w
NAME             CLUSTER-DEFINITION   TERMINATION-POLICY   STATUS     AGE
qdrant-cluster   qdrant               Delete               Creating   27s
qdrant-cluster   qdrant               Delete               Running    64s

kubectl get pods -l app.kubernetes.io/instance=qdrant-cluster -n demo

Stop the Qdrant Cluster

Stopping a cluster temporarily suspends operations while preserving all data and configuration:

Key Effects:

Compute resources (Pods) are released
Persistent storage (PVCs) remains intact
Service definitions are maintained
Cluster configuration is preserved
Operational costs are reduced

kubectl apply -f https://raw.githubusercontent.com/apecloud/kubeblocks-addons/refs/heads/main/examples/qdrant/stop.yaml


apiVersion: operations.kubeblocks.io/v1alpha1
kind: OpsRequest
metadata:
  name: qdrant-stop
  namespace: demo
spec:
  clusterName: qdrant-cluster
  type: Stop

Alternatively, stop by setting spec.componentSpecs.stop to true:


kubectl patch cluster qdrant-cluster -n demo --type='json' -p='[
{
  "op": "add",
  "path": "/spec/componentSpecs/0/stop",
  "value": true
}
]'


spec:
  componentSpecs:
    - name: qdrant
      stop: true  # Set to stop component
      replicas: 3

Start the Qdrant Cluster

Restarting a stopped cluster resumes operations with all data and configuration intact.

Key Effects:

Compute resources (Pods) are recreated
Services become available again
Cluster returns to previous state

kubectl apply -f https://raw.githubusercontent.com/apecloud/kubeblocks-addons/refs/heads/main/examples/qdrant/start.yaml


apiVersion: operations.kubeblocks.io/v1alpha1
kind: OpsRequest
metadata:
  name: qdrant-start
  namespace: demo
spec:
  clusterName: qdrant-cluster
  type: Start

Restart by setting spec.componentSpecs.stop to false:


kubectl patch cluster qdrant-cluster -n demo --type='json' -p='[
{
  "op": "remove",
  "path": "/spec/componentSpecs/0/stop"
}
]'

Delete Qdrant Cluster

Choose carefully based on your data retention needs:

Policy	Resources Removed	Data Removed	Recommended For
DoNotTerminate	None	None	Critical production clusters
Delete	All resources	PVCs deleted	Non-critical environments
WipeOut	All resources	Everything*	Test environments only

*Includes snapshots and backups in external storage

Pre-Deletion Checklist:

Verify no applications are using the cluster
Ensure required backups exist
Confirm proper terminationPolicy is set
Check for dependent resources

For test environments, use this complete cleanup:


kubectl patch cluster qdrant-cluster -p '{"spec":{"terminationPolicy":"WipeOut"}}' --type="merge" -n demo
kubectl delete cluster qdrant-cluster -n demo

NOTE

Version Compatibility

Always verify that the Qdrant Add-on version matches your KubeBlocks major version to avoid compatibility issues.

Verify Supported Qdrant Versions

List available Qdrant versions:

kubectl get cmpv qdrant

Example Output

Step 2. Get the list of ComponentDefinition associated with a given ComponentVersion


kubectl get cmpv qdrant -o json | jq -r '.spec.compatibilityRules[] | select(.compDefs | any(startswith("^qdrant"))) | .releases[]'

This returns versions compatible with ComponentDefinition named qdrant:

Delete Qdrant Cluster

Choose carefully based on your data retention needs:
