This project provides a complete setup for deploying a production-grade WordPress application on Kubernetes using Helm. It includes custom Docker images for WordPress, MySQL, and Nginx. Using Helm charts for managing Kubernetes resources.

• Docker
• Minikube
• Helm

1. Build the WordPress Docker image:

   cd ../wordpress
   docker build -t your-dockerhub-username/wordpress .

2. Build the MySQL Docker image:

   cd ../mysql
   docker build -t your-dockerhub-username/mysql .

3. Build the Nginx Docker image:

   cd ../nginx
   docker build -t your-dockerhub-username/nginx .

4. Push the images to Docker Hub:

   docker push your-dockerhub-username/wordpress
   docker push your-dockerhub-username/mysql
   docker push your-dockerhub-username/nginx

Update the values.yaml files for each Helm chart with the appropriate Docker image repositories and tags.

1. Deploy MySQL

   cd helm-charts/mysql
   helm install mysql .

2. Deploy WordPress:

   cd ../wordpress
   helm install wordpress .

3. Deploy Nginx:

   cd ../nginx
   helm install nginx .

1. Check Pods:

   kubectl get pods

2. Check services:

   kubectl get svc

3. Access wordpress:

   minikube ip

helm delete mysql
helm delete wordpress
helm delete nginx

1. Add the Prometheus Helm repository:

   helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
   helm repo update

2. Create a namespace for monitoring:

   kubectl create namespace monitoring

3. Deploy Prometheus:

   helm install prometheus prometheus-community/prometheus -f ./monitoring/prometheus/values.yaml

1. Add the Grafana Helm repository:

   helm repo add grafana https://grafana.github.io/helm-charts
   helm repo update

2. Deploy Prometheus:

   helm install grafana grafana/grafana -n monitoring

3. Get the Grafana admin password:

   kubectl get secret --namespace monitoring grafana -o jsonpath="{.data.admin-password}" | base64 --decode ; echo

4. Access Grafana:

   kubectl get svc -n monitoring

   Open the Grafana URL in your browser and log in with the username admin and the password obtained in the previous step.

Import predefined dashboards for MySQL, Nginx, and WordPress:

Go to Create > Import. Use the following dashboard IDs to import: MySQL: 7362 Nginx: 2135 WordPress: Create a custom dashboard with relevant metrics.
