The GitOps Kubernetes operator

Flux

Announcement Flux has joined CNCF as a sandbox project

We believe in GitOps:

  • You declaratively describe the entire desired state of yoursystem in git. This includes the apps, config, dashboards,monitoring and everything else.
  • What can be described can be automated. Use YAMLs to enforceconformance of the system. You don’t need to run kubectl, all changes gothrough git. Use diff tools to detect divergence between observed anddesired state and get notifications.
  • You push code not containers. Everything is controlled throughpull requests. There is no learning curve for new devs, they just useyour standard git PR process. The history in git allows you to recoverfrom any snapshot as you have a sequence of transactions. It is muchmore transparent to make operational changes by pull request, e.g.fix a production issue via a pull request instead of making changes tothe running system.

Flux is a tool that automatically ensures that the state of a clustermatches the config in git. It uses an operator in the cluster to triggerdeployments inside Kubernetes, which means you don’t need a separate CD tool.It monitors all relevant image repositories, detects new images, triggersdeployments and updates the desired running configuration based on that(and a configurable policy).

The benefits are: you don’t need to grant your CI access to the cluster, everychange is atomic and transactional, git has your audit log. Each transactioneither fails or succeeds cleanly. You’re entirely code centric and don’t neednew infrastructure.

Deployment Pipeline

What Flux does

Flux is most useful when used as a deployment tool at the end of aContinuous Delivery pipeline. Flux will make sure that your newcontainer images and config changes are propagated to the cluster.

History

In the first years of its existence, the development of Flux was veryclosely coupled to that of WeaveCloud. Over the years the communityaround Flux grew, the numbers of integrations grew andthe team started the process of generalising the code, so that more projectscould easily integrate.

Get started with Flux
