Terraform Module for Monitoring using Prometheus, Alertmanager and Grafana

This Terraform module makes it easy to setup Prometheus, Alertmanager and Grafana on AWS in a single EC2 instance.

Usage

To getting started make use of the module by adding the following line to Terraform file (e. g. main.tf):

module "monitoring" {
  source = "github.com/Lanseuo/terraform-prometheus-grafana"

  prometheus_hostname   = "prometheus.example.com"
  alertmanager_hostname = "alertmanager.example.com"
  grafana_hostname      = "grafana.example.com"
  config_bucket_name    = "my-monitoring-config"
}

In order to get the module you will have to (re)initialize Terraform:

terraform init

Now you can deploy to AWS:

terraform apply

This will create the necessary EC2 instance, the S3 bucket which is used for configuration, the necessary IAM configuration as well as the security groups.

Configuration

This Terraform module uses a S3 bucket to store the configuration for Prometheus, Alertmanager and Grafana.

To use your own configuration you have to apply the following folder structure:

- config
  - alertmanager
    - alertmanager.yml
  - grafana
    - provisioning
      - datasources
          datasource.yml
    - grafana.ini
  - prometheus
    - prometheus.yml
    - rules.yml

Sync your configuration to your S3 bucket and redeploy the module to get Prometheus, Alertmanager and Grafana to use your latest configuration.

aws s3 sync config s3://my-monitoring-config
