Installing MemoryGrid Management Services
MemoryGrid includes two key management services:
-
MemoryGrid Config Service – Responsible for deploying and configuring MemoryGrid local cluster services, including both in-memory and persistent storage instances.
-
Routing Service – Maintains metadata about objects (if sharing is enabled) and tracks all streaming queues across the MemoryGrid network.
Installing the Database
To install the database, run the following steps:
# From the project root
cd kubernetes/installer
# Usage: ./install_db.sh <replica-count> [storage-size]
./install_db.sh 3 5Gi
The above command provisions the MemoryGrid database with 3 replicas, each with 5Gi of storage.
Installing the Services
To deploy the management services, run the installer script:
# From the project root
cd kubernetes/installer
./install.sh
This will deploy both the MemoryGrid Config Service and the Routing Service.
Here is the final section with a table listing the deployed services and their respective NodePorts:
Services
The following services are deployed as part of the MemoryGrid management system:
| Service Name | Namespace | Description | Port | NodePort |
|---|---|---|---|---|
framedb-config-svc |
framedb-services |
MemoryGrid Config Service for managing MemoryGrid clusters and instances | 5000 | 30610 |
routing-service-svc |
framedb-services |
Routing Service to track object locations and streaming queues | 5000 | 30611 |
Note: Only the management services (
framedb-config-svc,routing-service-svc) are exposed via NodePort for external access. MongoDB replicas are internally accessible within the cluster.
Local cluster services
Following services are deployed on the local clusters through config service (refer config service documentation to understand how to spin up these services).
| Component | NodePort Range / Port | Internal Service URL |
|---|---|---|
| MemoryGrid Config Service | 32566 |
http://framedb-config.framedb-config.svc.cluster.local:5000 |
| Objects API | 32567 |
http://objects.framedb-config.svc.cluster.local:50051 |
| Decoder Scheduler | 32568 |
http://decoder-scheduler.framedb-config.svc.cluster.local:5000 |
| MemoryGrid In-Memory Instances | 30700–30900 |
Dynamic service URLs (one per in-memory instance, 200 instances per cluster) |
| MemoryGrid Persistent Instances | 30900–30999 |
Dynamic service URLs (one per persistent instance, 99 instances per cluster) |
Note: All MemoryGrid instances are assigned dynamic service names based on their deployment ID and exposed via unique NodePorts within the specified ranges.
