Project Objective

For this project, you are to setup a pipeline to deploy Cluster/Application Monitoring tools: Prometheus, and Grafana into the DB cluster using Terraform with the Kubernetes and Helm Providers.

Prerequisites

• Metrics Enabled in the values files for the following applications to allow Prometheus to track their performance:
  • Jenkins (ref: https://github.com/Ohubabs/DB-Pipeline.git)
  • SonarQube (ref: https://github.com/Ohubabs/DB-Sonarqube.git)
  • MongoDB (ref: https://github.com/Ohubabs/DB-Mongo.git)
  • Nginx-Ingress (ref: https://github.com/Ohubabs/DB-Pipeline.git)

Step 1: Go to New Item” from the Dashboard, select “Pipeline”, name it “Prometheus_Grafana”.

Step 2: Go to “Configuration”, Select “Poll SCM” and Enter the details for your GitHub repo & Jenkinsfile or copy and paste the Jenkinsfile_Monitor in this repo.

Notes :-

• Edit the var.tf file with your Grafana credentials to be uploaded into the secret in prince.tf.

• If you change the name of the secret, it must be edited as well in the graf-values.yml file

Step 3: Click “Build now” to deploy Cluster/Application Monitoring tools: Prometheus, and Grafana into the DB cluster .

Step 4: Once your Prometheus and Grafana sites are live, log into Grafana, set Prometheus as a data source, and gain performance stats from apps running in the cluster e.g Jenkins, SonarQube, etc...
