## REQUIREMENTS

1. A control node with git, terraform installed.

2. AWS account, AWS CLI installed and configured.

3. Terraform Installed on your local system.

## SETTING UP THE JENKINS SERVER

In the `jenkins-server` folder above, you will find the terraform code to set up the Jenkins server on ubuntu 20.04. Run the following commands to set up the server.

```bash

terraform init

terraform apply --auto-approve

```

This will create the VPC (and all its other components), I'm using a pre-existing keypair with it. You can change the keypair name in the `jenkins-server.tf` file. There's also a script to install all the required packages on the server. You can find it in the `ubuntu-script.sh`. When the infrastructure is complete, the public IP address of the server will be displayed. You can use this to access the server. `http://:8080`.

SSH into the server and display the required password to unlock Jenkins. You can use this to login to the server.

Configure your github and aws credentials, create a pipeline, and you are good to go.

## SETTING UP THE EKS CLUSTER AND DEPLOYING THE APPLICATIONS

In the `jenkins-pipeline/aws` folder, there are configurations files to provision the eks cluster.

In the `jenkins-pipeline/k8s` folder, there are configuration files to deploy the applications on the cluster and create a DNS on route53.

## MONITORING THE APPLICATIONS WITH PROMETHEUS

There are configuration files to deploy prometheus and grafana in the `jenkins-pipeline/manifests-monitoring` folder. You can use these to monitor the applications. To access the prometheus dashboard, you can use the following command on your jenkins server.

```bash

kubectl port-forward svc/prometheus-server 8081:9090 -n monitoring --address 0.0.0.0

```

To access the grafana dashboard, you can use the following command on your jenkins server.

```bash

kubectl port-forward svc/grafana 8082:80 -n monitoring --address 0.0.0.0

```
