associated Git workflow. This method can become hard to manage, but it scales incred- ibly well and is flexible enough to fit almost any organization. Directory Structures As explained in the previous section base and overlay the deltas. Since most GitOps tools support Kustomize, the combination allows a flexible deployment. For example, if one cluster is administered through Flux and another through Argo CD Using GitOps with CI/CD calls for a shift in thinking. Traditionally, you think of promoting code or images into environments. But GitOps with CI/CD changes that mindset. When working with GitOps workflows

to be built using modular ‘building blocks’ that work across any type of infrastructure, and are flexible enough to meet all the varied needs of the business. An internal platform is built not bought each change being made on the platform. Beyond this, it helps to build a platform that is modular, flexible, and importantly, secure. GitOps for internal platform building GitOps is a way to manage platforms platform building: Building and managing platforms can be challenging and requires an approach that is flexible, yet secure. GitOps fits the bill as the ideal solution for platform building. Here are the top

storage system of choice • Secret and configuration management − Note: Without rebuilding Docker images or exposing secrets • Self-healing abilities − I.e., restarting of the failed containers, replacing KUBERNETES REFCARD | SEPTEMBER 2022 6 With this typical CI/CD push-based pipeline, Docker container images are then deployed to the actual cluster using some sort of bespoke bash scripts or through some challenges as listed below: SECURITY With this approach, your CI tooling pushes and deploys images to the cluster. For the CI system to apply the changes to a cluster, you have to share your API

Docker image that gets pushed to the container registry. With a typical CI/CD pipeline, Docker images are deployed using some sort of bash script or another method of talking directly to the cluster How secure is the typical CI/CD pipeline? With this approach, your CI tooling pushes and deploys images to the cluster. For the CI system to apply the changes to a cluster, you have to share your API called front-end. This is the container repository that will be used by Travis CI to push the new images. 2. Sign up for a Travis Continuous Integration Account If you already have your own CI system
