Kubernetes Integration

Ordo can be easily deployed into a Kubernetes cluster. As a stateless service, Ordo works perfectly in a K8s environment.

Deployment Manifests

Below is a standard Kubernetes manifest including a Deployment and a Service.

Deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: ordo-server
  labels:
    app: ordo
spec:
  replicas: 2
  selector:
    matchLabels:
      app: ordo
  template:

      labels:

    spec:
      containers:
        - name: ordo-server
          image: ghcr.io/pama-lee/ordo-server:latest
          imagePullPolicy: Always
          ports:
            - containerPort: 8080
              name: http
            - containerPort: 50051
              name: grpc
          livenessProbe:
            httpGet:
              path: /health
              port: http
            initialDelaySeconds: 5
            periodSeconds: 10
          readinessProbe:
            httpGet:
              path: /health
              port: http
            initialDelaySeconds: 2
            periodSeconds: 5
          resources:
            requests:
              cpu: '100m'
              memory: '128Mi'
            limits:
              cpu: '500m'
              memory: '512Mi'
          env:
            - name: RUST_LOG
              value: 'info'

Service

apiVersion: v1
kind: Service
metadata:
  name: ordo-service
spec:
  selector:
    app: ordo
  ports:
    - protocol: TCP
      port: 80
      targetPort: 8080
      name: http
    - protocol: TCP
      port: 50051
      targetPort: 50051
      name: grpc
  type: ClusterIP

Configuration Notes

• Health Checks: Liveness and Readiness probes are configured pointing to the /health endpoint.
• Ports: Container exposes 8080 (HTTP) and 50051 (gRPC).
• Resource Limits: Adjust CPU and memory requests/limits based on your load.
• Scaling: Easily scale the service by changing the replicas count.

Deployment

Save the above configuration as ordo-k8s.yaml and run:

kubectl apply -f ordo-k8s.yaml

Check deployment status:

kubectl get pods -l app=ordo
