Git Repositories Structures

• GitOps: How to Ops Your Git the Right Way 🌟 In this article we’ll look into the specifics of creating Git repositories structures  —  the very core of the GitOps approach.

GitOps Tools

• FluxCD, ArgoCD or Jenkins X: Which Is the Right GitOps Tool for You?
• slideshare: GitOps, Jenkins X & Future of CI/CD
• kubesandclouds.com: Werf: Fully customizable GitOps
• searchitoperations.techtarget.com: GitOps pros grapple with Kubernetes configuration management. GitOps users seek ideal Kubernetes config tool 🌟 Configuration management challenges GitOps early adopters, especially at large enterprises with millions of lines of Kubernetes YAML to manage. Ultimately, the industry hasn't found an ideal approach to Kubernetes configuration management, especially for GitOps.
  • Tanka a utility that blends Helm charts with Jsonnet, which combines the deployment speed and ubiquity of Helm charts with the more granular customizability supported by Jsonnet.

  • Use a Git branch per environment
  • Practice proper change management
  • Roll back with Git
  • Automate everything

Kustomize. Kubernetes native configuration management

• kustomize.io 🌟 Kustomize introduces a template-free way to customize application configuration that simplifies the use of off-the-shelf applications. Now, built into kubectl as apply -k.

Jenkins

• There are many tools in the market that have been technically built for GitOps, like ArgoCD, Flux, and Jenkins X. All these tools have in-built proficiency to implement GitOps process for you. But we are going to use our old beloved Jenkins.
• GitOps for Kubernetes with Jenkins
  • github.com/stakater/Xposer (with fabric8 java client library for kubernetes)
• GitOps with Jenkins and Kubernetes
  • github.com: Opstree-Go-WebApp A loaded GoLang app to do various DevOps POC's
  • opstree.github.io

Terraform

Config Sync and Anthos Config Management

• Config Sync
• Anthos Config Management
• Google built a tool called Config Sync which acts as the bridge between an external source code repository and the Kubernetes API server. Anthos Config Management is based on Config Sync to extend it to multicluster scenarios.

Portworx AutoPilot

OpenShift Applier

• openshift-applier
• dzone: GitOps With OpenShift Applier 🌟 GitOps in short is a set of practices to use Git pull requests to manage infrastructure and application configurations.

GitOps Frameworks

• dzone: Why Now Is the Time for the Spring Boot of Infrastructure Automation 🌟 Application teams move fast using frameworks built to boost developer productivity. Learn how a productivity framework can help your DevOps initiative succeed.
• Kubestack 🌟 is an open-source GitOps framework for infrastructure automation built on Terraform and Kustomize. It’s designed for teams that want to automate Kubernetes based infrastructure and not reinvent automation. Think of it this way, Kubestack is to Terraform and infrastructure automation, what Spring Boot is to Java and cloud native applications. The framework supports all three major cloud providers and has been used as the foundation for a number of real world customer projects as part of my colleagues’ and my consulting work. It is fully documented, has a step-by-step tutorial to help users get started and even includes a local GitOps development lab. So you can test-drive Kubestack and learn more about GitOps for infrastructure automation in the comfort of your own localhost.
