Introduction

This document provides a comprehensive guide to install and configure the Raven Platform in your Kubernetes (K8s) clusters using Helm charts. This guide is intended for platform engineers and administrators who are responsible for deploying and managing the Raven platform within their infrastructure.

​
Prerequisites

Before proceeding with the Helm installation, ensure you have completed the following prerequisites:
  1. AWS Setup: Follow the AWS setup steps mentioned here using Terraform to create the necessary resources, including:We provide a Terraform example repository to assist you with this setup, which can be found here.
    • RDS Database
    • Elasticache Redis
    • ClickHouse Database
    • Secrets
    • EKS Cluster
    • Required IAM Roles
  2. Helm Installation: Ensure Helm is installed on your local machine. You can find the installation guide here.
  3. Helm Registry Login: You need to log in to the Helm registry using your provided username and password.

​
Step-by-Step Guide

​
Step 1: Login to Helm Registry

First, authenticate with the Helm registry to access the Raven platform charts. 
helm registry login releases.cloud.raven.io
You will be prompted to enter your username and password. Ensure you have these credentials handy.

​
Step 2: Fetch Helm Chart Values

To customize your Helm chart installation, you may want to review the possible configuration values. Use the following command to display all configurable parameters. 
helm show values oci://releases.cloud.raven.io/self-hosted/raven-platform

​
Step 3: Install the Raven Platform Helm Chart

Once authenticated and aware of the configurable values, you can proceed to install the Raven platform Helm chart. Replace <your-namespace> with the namespace where you want to deploy the platform and customize the <config.yaml> with your specific configurations. 
helm install raven-platform oci://releases.cloud.raven.io/self-hosted/raven-platform --namespace <your-namespace> -f <config.yaml>

​
Example Configuration (config.yaml)

Below is an example config.yaml to illustrate how you might configure your Helm chart: 
imageCredentials:
  name: raven-platform-image
  username: user  # Your Docker registry username
  password: "user!!!"  # Your Docker registry password
  existingSecret: ""

            pathType: ImplementationSpecific
    tls:
      - hosts:
        - query.raven.yourdomain.com
        secretName: query-raven-yourdomain-com

raven-ui:

    hosts:
      - host: raven.yourdomain.com
        paths:
          - path: /
            pathType: ImplementationSpecific

    tls:
      - hosts:
        - upload.raven.yourdomain.com
        secretName: upload-raven-yourdomain-com

​
Step 4: Verify Installation

After the installation command completes, verify that all resources are created and running as expected. 
kubectl get pods -n <your-namespace>
kubectl get svc -n <your-namespace>

​
Step 5: Access the Raven Platform

Once all pods are running and the services are up, you can access the Raven platform via the ingress host specified in your configuration (raven.yourdomain.com).
