Ish Bot Deployment

This repository contains infrastructure and deployment configurations for the Ish Bot application, which is deployed on Kubernetes clusters across AWS and GCP.

Overview

The Ish Bot is a web-based bot application that runs in a containerized environment. It is deployed using Kubernetes manifests and managed via Terraform infrastructure code. The project supports deployment on both AWS and GCP cloud providers.

Setup Instructions

Prerequisites

• Terraform installed
• kubectl installed
• AWS or GCP account credentials configured

Infrastructure Setup

1. Navigate to the terraform directory and choose your cloud provider (AWS or GCP).
2. Initialize Terraform:

   terraform init

3. Apply the Terraform configuration:

   terraform apply

Kubernetes Cluster Setup

1. Use the scripts in the scripts/k8s directory to set up the Kubernetes cluster:

   • Run install_control_plane.sh on the control plane node.
   • Run install_worker.sh on each worker node.
   • Run start_etcd.sh on the etcd node.
   • Run start_control_plane.sh on the control plane node.
   • Run start_worker.sh on each worker node.

2. Generate the necessary kubeconfig files:

   • Run generate_admin_config.sh to generate the admin kubeconfig.
   • Run generate_kubelet_config.sh on each worker node.

Deploying the Ish Bot

1. Apply the Kubernetes manifests in the k8s directory:

   kubectl apply -f k8s/config.yml
   kubectl apply -f k8s/deployment.yml
   kubectl apply -f k8s/service.yml

2. Apply the storage configurations:

   kubectl apply -f others/storageclass.yml
   kubectl apply -f others/gcp_storageclass.yml
   kubectl apply -f others/pvc.yml
