##KUBERNETES CI CD PREREQUISITES <a name="Kubernetes-CI-CD-Prerequisites"></a>
If you have not set up Kubernetes yet, here are some instructions to get you started.

- [Setup a Kubernetes Production Environment] (https://kubernetes.io/docs/setup/production-environment/)
- [Setup a Kubernetes Container Runtime] (https://kubernetes.io/docs/setup/production-environment/container-runtimes/https://kubernetes.io/docs/setup/production-environment/container-runtimes/)

You can also setup Kubernetes clusters with KubeAdmin, Kops, or Kubespray. Once you’ve got Kubernetes deployed and your applications are setup in your version control system, you’re all set to wire up CI CD from your applications to Kubernetes. We will not walk through the Kubernetes setup in this article, but you can join our mailing list to receive technical guides on these topics.

##WERF: GITOPS DELIVERY TOOL <a name="Werf:-Gitops-Delivery-Tool"></a>

##[Werf] (https://github.com/werf/werf)

###DESCRIPTION:
Werf is an Open Source CLI tool written in Go, designed to simplify and speed up the delivery of applications. To use it, you need to describe the configuration of your application (in other words, how to build and deploy it to Kubernetes) and store it in a Git repo — the latter acts as a single source of truth. In short, that’s what we call GitOps today.

Werf is not a complete Kubernetes CI/CD tool, but a solution for creating pipelines that can be embedded into any existing CI/CD system. It literally “connects the dots” to bring these practices into your application. We consider it a new generation of high-level CI/CD tools.

###BENEFITS:
- Werf builds Docker images using Dockerfiles or an alternative fast built-in builder based on the custom syntax. It also deletes unused images from the Docker registry.
- Werf deploys your application to Kubernetes using a chart in the Helm-compatible format with handy customizations and improved rollout tracking mechanism, error detection, and log output.

###FEATURES:
- Full application lifecycle management: build and publish images, deploy an application to Kubernetes, and remove unused images based on policies.
- The description of all rules for building and deploying an application (that may have any number of components) is stored in a single Git repository along with the source code (Single Source Of Truth).
- Build images using Dockerfiles.
- Alternatively, werf provides a custom builder tool with support for custom syntax, Ansible, and incremental rebuilds based on Git history.
- Werf supports Helm compatible charts and complex fault-tolerant deployment processes with logging, tracking, early error detection, and annotations to customize the tracking logic of specific resources.
- Werf is a CLI tool written in Go. It can be embedded into any existing CI/CD system to implement CI/CD for your application.
- Cross-platform development: Linux-based containers can be run on Linux, macOS, and Windows.

##FLUX: OPEN AND EXTENSIBLE CONTINUOUS DELIVERY FOR KUBERNETES <a name="Flux:-Open-And-Extensible-Continuous-Delivery-For-Kubernetes"></a>

##[Flux] (https://github.com/fluxcd/flux2)

###DESCRIPTION:
Flux is a tool for keeping Kubernetes clusters in sync with sources of configuration (like Git repositories), and automating updates to configuration when there is new code to deploy.

Flux version 2 (“v2”) is built from the ground up to use Kubernetes’ API extension system, and to integrate with Prometheus and other core components of the Kubernetes ecosystem. In version 2, Flux supports multi-tenancy and support for syncing an arbitrary number of Git repositories, among other long-requested features.

Flux v2 is constructed with the GitOps Toolkit, a set of composable APIs and specialized tools for building Continuous Delivery on top of Kubernetes.

###BENEFITS:
- Flux and Flagger deploy apps with canaries, feature flags, and A/B rollouts. Flux can also manage any Kubernetes resource. Infrastructure and workload dependency management is built in.
- Enables application deployment (CD) and (with the help of Flagger) progressive delivery (PD) through automatic reconciliation. Flux can even push back to Git for you with automated container image updates to Git (image scanning and patching).
- Works with your Git providers (GitHub, GitLab, Bitbucket, can even use s3-compatible buckets as a source), all major container registries, and all CI workflow providers.
- Kustomize, Helm, RBAC, and policy-driven validation (OPA, Kyverno, admission controllers) so it simply falls into place.
- Uses true Kubernetes RBAC via impersonation and supports multiple Git repositories. Multi-cluster infrastructure and apps work out of the box with Cluster API: Flux can use one Kubernetes cluster to manage apps in either the same or other clusters, spin up additional clusters themselves, and manage clusters including lifecycle and fleets.
- Provides health assessments, alerting to external systems, and external events handling. Just “git push”, and get notified on Slack and other chat systems.
- Flux is a CNCF Incubating project and was categorised as “Adopt” on the CNCF CI/CD Tech Radar (alongside Helm).
- We welcome contributors of any kind. The components of Flux are on Kubernetes core controller-runtime, so anyone can contribute and its functionality can be extended very easily.

###FEATURES:
- Describe the entire desired state of your system in Git. This includes apps, configuration, dashboards, monitoring, and everything else.
- Use YAML to enforce conformance to the declared system. You don’t need to run kubectl because all changes are synced automatically.
- Everything is controlled through pull requests. Your Git history provides a sequence of transactions, allowing you to recover state from any snapshot.
- Declaratively configurable using Custom Resources, state reports in the object’s status and via Kubernetes Events, and integrations with Kubernetes RBAC
- Support for e.g. Kustomize, Helm; GitHub, GitLab, Harbor and custom webhooks; notifications to most team communication platforms; and many more.
- Easily create a continuous delivery solution with only the components you need, or use the GitOps Toolkit to extend Flux.
