Smart DIH Kubernetes Installation

This is an installation guide for Smart DIH in H/A mode. Upon completion of this guide, the user will have a functional Smart DIH Digital Integration Hub. An application architecture that decouples digital applications from the systems of record, and aggregates operational data into a low-latency data fabric. together with the ability to operate is using the SpaceDeck UI

.

Prerequisites

Following are the prerequisites required for deploying Smart DIH using Kubernetes An open-source container orchestration system for automating software deployment, scaling, and management..

• Kubernetes cluster version >1.22

• At least a total of 20GB and 10 vCPU

• Kubectl and helm applications installed.

• See Appendix A for:

  • Certificate manager deployment

  • Metrics-service deployment

  • Ingress controller installation in order to connect to the SpaceDeck GigaSpaces intuitive, streamlined user interface to set up, manage and control their environment. Using SpaceDeck, users can define the tools to bring legacy System of Record (SoR) databases into the in-memory data grid that is the core of the GigaSpaces system. UI.

• A load balancer that is securely exposed to the internet and connected to the ingress controller

• DNS setup with a certificate for a secure connection. The instructions below assume the host name to be myhost.com.

Instructions

1. Use the gsSecret.yaml you got from GigaSpaces to install the software token.

2. Get the Smart DIH Helm repo and update:

helm repo add dih https://resources.gigaspaces.com/helm-charts-dih 

helm repo update dih

3. Fully install Smart DIH (including Ingress, H/A for SpaceDeck and IIDR):

helm install dih dih/dih --version 16.4.0 --set spacedeck.ingress.host=myhost.com,tags.iidr=true, 
global.password=rootpassword

4. If IIDR installation is NOT included then use this:

   helm install dih dih/dih --version 16.4.0 --set global.ingressHost=myhost.com  
   

5. Smart DIH is now installed in H/A mode. Wait for all pods to be ready.

6. Connect to the SpaceDeck at https://myhost.com/

Next Steps

1. Install the agent for the required data sources: DI Agent Installation: Prerequisites

2. Use SpaceDeck to define spaces, data sources and pipelines.

   By default, the root user has root/password credentials.  This must be changed before installation using the parameter of global.password seen in step 3 of the Instructions section above.

Appendix A

• Certificate manager deployment.  Follow these instructions (external link).

• Metrics-service deployment. Follow these instructions (external link).

• An ingress controller is required as part of the Smart DIH installation. Follow these Instructions for NGINX controller installation (external link). It is best practice to install NGINX in a different name-space.
