Replicated deployment with Sentinel

​

When to use this

• spec.topology: replication
• spec.replicas from the FalkorDB replica count
• spec.sentinel.enabled: true
• spec.sentinel.replicas from the Sentinel node count

​

Create from Admin UI

1. Open Deployments > Create Deployment.
2. Choose Standalone.
3. Choose QA or Prod to start from a Sentinel-enabled template, or choose Full Setup and enable Sentinel manually.
4. In FalkorDB, set the FalkorDB replica count. Prod requires at least 2.
5. In Sentinel, enable Sentinel and set an odd number of Sentinel replicas. The UI defaults to 3.
6. Configure Sentinel CPU, memory, storage, and optional node affinity.
7. Optionally add a Sentinel service in Networking, or set an external domain for stable per-pod DNS names outside the cluster — see Networking.
8. Complete auth, TLS, backup, parameters, and review.
