In 1st part of this series, we will learn basic concepts of Rancher, and then we will create “Rancher server” using terraform file, also we will learn doing with manuel installation it too. Finally, we will deploy Rancher into cluster in Rancher server and examine the created cluster structure. We will do it all step by step.

In 2nd part of this article: “Deploying microservices java application to the cluster created with Rancher using Helm”.

Nelmis emerging as a promising alternative to Helm. It is a part of a bigger CNCF project calledwerf, which aims to improve your Kubernetes-based CI/CD. Being backward-compatible with Helm, Nelm comes with significant improvements and new features that pull your deployment experience ahead. Learn m..

werf is a CLI tool for CI/CD created in 2016 and a CNCF Sandbox project since 2022. It implements opinionated CI/CD in Kubernetes with your favourite CI system. Starting from werf v2, it uses Nelm instead of Helm to deploy container images.

Helm dry run, using the helm install --dry-run command, is a valuable technique for validating Helm charts before deployment on a Kubernetes cluster. It helps avoid errors and unexpected behavior by simulating the installation process without modifying the cluster. Helm dry run works alongside other Helm commands like helm template and helm lint to streamline development and ensure charts are well-structured, compatible, and ready for deployment.
