linear, basing each stage on previous ones. That’s why the term commonly used for the CI/CD build/test/deploy process is a pipeline. It can provide integration, delivery, and deployment in a continuous manifests are generally the same, and there are only slight differences between them in the dev and test environments. Now let’s do some customization. To render the YAML output for the dev environ- ment Branches Another best practice that surprises many programmers is to separate environments– such as test and production–into different directories, but not create branches for them. Like the separation

leverages Istio as its service mesh, and one aspect of Istio is its reliance on sidecars for secure network communication. Sidecars, which are language agnostic, act as service proxies and allow for all traffic release pattern that allows you to release a new feature to a small percentage of users, let them test it out, and if it works well enough, make it available to everyone. It is a great way to enhance GitOps maturity. However, if your 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
