- thenewstack.io: CNCF Working Group Sets Some Standards for ‘GitOps’ GitOps must meet these four requirements:
- Declarative: A system managed by GitOps must have its desired state expressed declaratively. “You’re no longer giving instructions, you’re describing state,” Murillo described.
- Versioned and Immutable: Desired state is stored in a way that enforces immutability, versioning and retains a complete version history. “The only way for you to introduce change in your system is by creating a new version of your desired state,’ Murillo added.
- Pulled Automatically: Software agents automatically pull the desired state declarations from the source. Agents within the system pull the desired state from the repository.
- Continuously Reconciled: Software agents continuously observe the actual system state and attempt to apply the desired state. “The desired state [of the system or software] is continually reconciled, Murillo said.

GitOps Working Group
- GitOps Working Group 🌟
- The Five GitOps Principles (as defined by the GitOps Working Group) to the lifecycle of an infrastructure resource, like a virtual machine or load balancer:
- Declarative Configuration (define the resource as code)
- Version controlled (use source control to manage the resource definition)
- Automated delivery (provision and manage the resource from the definition using automation)
- Software Agents (implement automated configuration management for the resource)
- Closed loop (build the delivery pipeline for integration testing for resource changes)
Git Repositories Structures
- dzone: 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.
- codefresh.io: Stop Using Branches for Deploying to Different GitOps Environments How do I promote a release to the next environment? You should NOT use Git branches for modeling different environments. If the Git repository holding your configuration (manifests/templates in the case of Kubernetes) has branches named “staging”, “QA”, “Production” and so on, then you have fallen into a trap. Using branches for different environments should only be applied to legacy applications.

This allows organizations to manage multiple developer platforms, who can operate across many environments such as on premise, hybrid and multiple clouds.
- Streamlined processes and automation is pivotal for operations when managing clusters at scale and maintaining security and policy checks. Paul Curtis, Principal Solutions Architect will demonstrate GitOps and Weave Kubernetes Platform in a hybrid and multi-cloud setup.
- Learn how to:
- Use model-driven automation to increases reliability and stability across environments
- Simplify multi-cluster management with GitOps
- Enable developers to push code to production daily (self-service)
- Improve utilization and capacity management through Kubernetes platforms on cloud and on-premise infrastructure

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.

THREAD: What is GitOps?— Daniele Polencic (@danielepolencic) July 29, 2020
Is this something that you should learn?
Let's dive into it. pic.twitter.com/hsMUesvP23
If you do a canary release on #Kubernetes with #Istio use Flagger (https://t.co/4s6NFwvaXz). It allows e.g.:— Piotr Mińkowski (@piotr_minkowski) September 17, 2021
🔹 run acceptance and load tests
🔹 do an automatic rollback
🔹 make a progressive traffic shifting
If it takes me 5 minutes to rename a method and 1 hour to get a review and PR approval, that means wait to processing time ratio is 60/5=12, and flow efficiency is only 7.7%.— Dragan Stepanović (@d_stepanovic) December 24, 2021
Do you really think that a system this inefficient is incentivizing refactoring and small steps?
Unpopular opinion: GitOps should use Control Loops, not outdated CI/CD pipelines.— Ivan Velichko (@iximiuz) February 2, 2022
Control Loops is a much more powerful pattern than CI/CD.
CI/CD is just a way to push a change forward. But what about a feedback loop? Who restores the drifted prod state back to the desired one?
