Terraform module which creates EKS Cluster and dependent resources on AWS.

## Notice
#### This module install several Helm charts with limited inputs for their configuration, in order to keep it easy and simple. For a more accurate configuration we recommend to read their documentation and make your own installation of your desired Helm charts:
- [Metrics Server Helm chart](https://github.com/bitnami/charts/tree/master/bitnami/metrics-server/#installing-the-chart)
- [Ingress NGINX Helm Chart](https://github.com/kubernetes/ingress-nginx/tree/main/charts/ingress-nginx)
- [Cluster Autoscaler Helm Chart](https://github.com/kubernetes/autoscaler/tree/master/charts/cluster-autoscaler)
- [Cert Manager Helm Chart](https://github.com/cert-manager/cert-manager/tree/master/deploy/charts/cert-manager)
- [Kube Prometheus Stack Helm Chart](https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack)
- [Loki Distributed Helm Chart](https://github.com/grafana/helm-charts/tree/main/charts/loki-distributed)
- [Fluent Bit Helm Chart](https://github.com/fluent/helm-charts/tree/main/charts/fluent-bit)
- [Tempo Distributed Helm Chart](https://github.com/grafana/helm-charts/tree/main/charts/tempo-distributed)
