If you prefer to host Lightup in your own environment, Lightup Hybrid can be deployed to a dedicated VM or to an existing Kubernetes cluster (self-managed or cloud-managed).

Lightup Hybrid deployment keeps all data-oriented processes, such as metric collection, monitor training, integrations, and alerting, within your environment.

This page provides prerequisites to help you prepare for Lightup deployment. Please contact Lightup Support to arrange for actual deployment.

Prerequisites

Outbound connectivity

Your system instance must always have access to the following internet services for the proper functioning of Lightup. You should modify your firewall rules if you cannot access any of these services.

Deployment environment

Cloud-Managed Kubernetes (EKS, AKS, GKE)

If you’re using AWS EKS for your Kubernetes cluster, make sure that the following add-ons or equivalent have been installed:

• Amazon VPC CNI or equivalent
• CoreDNS
• kube-proxy
• Amazon EBS CSI or equivalent

Custom Lightup Access Point

Lightup exposes a NodePort on port 30443 that you can use to access the Lightup UI.

If the nodes in your kubernetes cluster have public IP addresses, then you can access the UI at https\://<ip-address-or-host-name-of-your-VM>:30443. If the nodes do not have a public IP address or if you want to configure a URL, you can use a Load Balancer to access the UI. Lightup only works with supported domains, so you'll need to provide Lightup support with your IP address / hostname / URL.

The following example shows how you'd access the Lightup UI at https://lightup.my-company.com using a Network Load Balancer in AWS:

1. Create a certificate for lightup.my-company.com with AWS Certificate Manager (ACM).

2. Verify the certificate with the option to create records in Route 53.

3. Copy the certificate ARN— you'll need this for the following step.

4. Update the following manifest for the Kubernetes service that will generate the NLB, and save it as a file named lightup-nlb-service.yaml:

   YAML

    apiVersion: v1  
      kind: Service  
      metadata:  
        name: lightup-backend  
        annotations:  
          external-dns.alpha.kubernetes.io/hostname: lightup.my-company.com  
          service.beta.kubernetes.io/aws-load-balancer-ssl-cert: YOUR_COPIED_CERTIFICATE_ARN  
          service.beta.kubernetes.io/aws-load-balancer-ssl-negotiation-policy: ELBSecurityPolicy-FS-1-2-Res-2020-10  
          service.beta.kubernetes.io/aws-load-balancer-type: nlb  
        labels:  
          app: backend  
      spec:  
        externalTrafficPolicy: Local  
        loadBalancerSourceRanges:
   	 - 0.0.0.0/0  
     ports:
      - name: backend  
         port: 443  
         protocol: TCP  
         targetPort: 8000  
     selector:  
       app: backend  
       release: backend  
     type: LoadBalancer
   

5. Deploy the NLB using kubectl and the YAML file you saved:
   kubectl apply -n lightup -f lightup-nlb-service.yaml

6. Copy the generated NLB's URL.

7. Create a new Route 53 A record for lightup.my-company.com to route to the NLB's URL.
