continuous stream of releases. Figure 1-1: The CI/CD workflow. Continuous integration builds and tests new code changes and merges them into a shared repository on a regular basis. CI is a form of rapid delivery one step further, deploying the changes into actual production (after they pass automated tests). Continuous deploy- ment supersedes continuous delivery and is now seen as full DevOps automation 4] in Kubernetes. A CRD lets you define a resource Kubernetes can manage that is not part of the core primitives that Kubernetes is used to working with. For example, Kubernetes knows how to work with

We will also review core benefits over the traditional CI/CD approach. TRADITIONAL CI/CD WORKFLOW OVERVIEW Before diving

what happens in the system ● Code changes always go through an automated process ● Deployments, tests, and rollbacks controlled through Git flow ● Integration with secrets providers ● No hand-rolled already there. This means that tasks such as… ● Compiling code ● Running unit/integration tests ● Security scanning ● Static analysis ...are not a concern of GitOps tools and are assumed that you want to run some smoke tests AFTER a deployment has finished and the result of the tests will decide if a rollback will take place or not. Smoke tests As I said in the previous

We have a handful of what we call core locations, 20 to 25, then there are near edge locations and there are more than 10,000 edge locations organization is at an early stage in this journey and you’d like to test the waters first, Weave GitOps Core is the underlying open source project that any organization can get started with. It includes many they need for development and monitoring. With RBAC, SSO, and Git’s version control, you can make core DevSecOps practices the norm without any added effort.

In this ebook you will learn: • a refresher on the the core principles of GitOps, • how your deployment strategy affects your GitOps plan, and • why observability to see in your GitOps strategy, be sure to remember those foundational elements: stay true to the core GitOps principles, understand your deployment strategy, and be sure to empower your team with observability
