approach of high-performing DevOps teams is to deploy an internal platform that developers use to create and access the resources they need on their own. THE GITOPS GUIDE TO BUILDING & MANAGING INTERNAL declared in Git and any changes are initiated using a simple pull request. GitOps allows you to create and manage your entire software stack through Git and treat your servers as your source code. Every Investments, a leading global financial services firm, faced the challenge that every application they create must meet a unique mix of regulatory, security, and governance requirements. The team at Fidelity

ways to extend it even further. In CustomResourceDefinitions (CRDs), Kubernetes users had a way to create all sorts of technology on Kubernetes clusters using familiar patterns. A more refined way to manage clusters, regulatory restrictions, and anything else in your organization that might force you to create a lot of YAML with only slight variations between files. Luckily, there are tools that help you into the parameters defined in the templates, and Helm injects these values into the manifests to create a release. A release is the end- Chapter 3 – Templating The Path to GitOps | 20 state representation

testing) are conveniently left out of the GitOps paradigm, and teams that adopt GitOps need to create their own best practices for all aspects of software delivery. Therefore you cannot simply “adopt Environment promotion The basic scenario for one environment is obvious. You merge (or create a commit) in Git, and your cluster for environment X is now getting the new version. But how do but I consider these workarounds as simple hacks that move away from the main GitOps promise and ​create several other issues​ in the long run. There is no standard practice for GitOps rollbacks The

up into microservices that can each be owned by a single team. Organizational leaders must also create a new culture that celebrates iterating and failing fast. Moving to DevOps is almost always worth quickly without compromising on reliability or security. “Leveraging GitOps has allowed us to create a self-service platform for engineers so they can concentrate on delivering business value through

infrastructure engineer will: Declare the infrastructure as code. 1. Push the code to a Git repository. 2. Create a pull request. 3. After that, this code can be reviewed and scrutinized by another team member quickly roll back to a previous state of the infrastructure seamlessly. Then they can again review and create infrastructure changes that address all these issues and trigger the CI/CD pipeline to deploy the

Velocity equates to competitive business success the time it takes to restore service has been cut drastically.
