Reconfiguring TLS for Qdrant

This guide will give an overview of how KubeDB Ops-manager reconfigures TLS for a Qdrant database.

QdrantOpsRequest CRD Specification:

KubeDB uses the following CRD fields to reconfigure TLS in Qdrant.

• spec:
  • type: ReconfigureTLS
  • tls:
    • issuerRef
    • certificates
    • client
    • p2p
    • rotateCertificates
    • remove

Read about the fields in detail from the QdrantOpsRequest Concepts page.

Before You Begin

• You should be familiar with the following KubeDB concepts:
  • Qdrant
  • QdrantOpsRequest
  • TLS Overview
• Use the example files from docs/examples/qdrant/quickstart/distributed.yaml and docs/examples/qdrant/reconfigure-tls/.

kubectl create ns demo

Deploy Qdrant

kubectl apply -f https://github.com/kubedb/docs/raw/v2026.6.5-rc.1/docs/examples/qdrant/quickstart/distributed.yaml
kubectl get qdrant -n demo qdrant-sample -w

How Reconfigure TLS Works

The following figure shows how KubeDB reconfigures TLS in Qdrant. Open the image in a new tab to see the enlarged version.

The Reconfigure TLS process consists of the following steps:

1. At first, a user creates a Qdrant CR.

2. KubeDB-Provisioner operator watches the Qdrant CR.

3. When the operator finds a Qdrant CR, it creates a PetSet and related necessary resources like secrets, services, etc.

4. Then, in order to reconfigure TLS of the Qdrant database, the user creates a QdrantOpsRequest CR specifying the desired TLS configuration. The user can add TLS to an existing non-TLS database, rotate the existing certificates, change the issuer, or remove TLS entirely.

5. KubeDB Ops-manager operator watches the QdrantOpsRequest CR.

6. When it finds a QdrantOpsRequest CR, it pauses the Qdrant object so that the KubeDB-Provisioner operator doesn’t perform any operations on the Qdrant during the TLS reconfiguration process.

7. Then the KubeDB Ops-manager operator updates the TLS secrets and restarts the pods in a rolling fashion with the new TLS configuration.

8. After the successful TLS reconfiguration, the KubeDB Ops-manager updates the Qdrant object to reflect the updated TLS state.

9. After the successful Reconfigure TLS, the KubeDB Ops-manager resumes the Qdrant object so that the KubeDB-Provisioner resumes its usual operations.

KubeDB supports the following TLS reconfiguration operations for Qdrant:

• Add TLS — Enable TLS on an existing non-TLS Qdrant database.
• Rotate TLS — Rotate the existing TLS certificates to refresh expiring certificates.
• Remove TLS — Remove TLS from an existing TLS-enabled Qdrant database.

In the next doc, we are going to show a step-by-step guide on reconfiguring TLS for a Qdrant database using QdrantOpsRequest CRD.
