We started the “Production Stage of the Microservices App” section with this article. In the production stage, whenever the developers push their codes to the main branch of the GitHub repository, the Jenkins pipeline will run automatically thanks to the GitHub webhook and automatically update our Java-based application running on the web. We will prepare the “Production Environment and Jenkins Production Pipeline” using Jenkins, Rancher, Docker, Maven, Amazon EKS, Amazon ECR, Amazon RDS, Amazon S3, Amazon Route53, Let’s Encrypt, Cert Manager, AWS Certificate Manager, Nexus, Prometheus and Grafana”. In this article, we will explain Production Stage and create a Kubernetes cluster using Amazon EKS. We will do it all step by step.

We will install Helm on the Ubuntu server, and then create and manage Helm charts. We will deploy the Java microservices app into the GCP Kubernetes Cluster by using the helm chart. Also, we will create a NOTES.txt, and assign image and repository values to “web-app.yaml” file from the “values.yaml” and “chart.yaml” files. Finally, we will observe the Kubernetes cluster and uninstall the chart release from the Kubernetes cluster by using helm commands. We will do these practically step by step in this article.

In this article series, I will talk about the installation, concepts, and usage of SonarQube, Trivy, OWASP Dependency Check, OWASP ZAP, and JaCoCo.
