Benefits

GitOps for apps and infrastructure

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.

Declarative & Automated

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.

Auditable

Everything is controlled through pull requests. Your Git history provides a sequence of transactions, allowing you to recover state from any snapshot.

Features

Push to Git and Flux does the rest

Flux 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 existing tools

Flux works with your Git providers (GitHub, GitLab, Bitbucket, can even use s3-compatible buckets as a source), all major container registries, fully integrates with OCI and all CI workflow providers.

Designed with security in mind

Pull vs. Push, least amount of privileges, adherence to Kubernetes security policies and tight integration with security tools and best-practices. Read more about our security considerations.

Does Multi-Tenancy (and “Multi-everything”)

Flux 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.

Works with any Kubernetes and all common tooling

Support for e.g. Kustomize, Helm; GitHub, GitLab, Harbor and custom webhooks; notifications on Slack and other chat systems; RBAC, and policy-driven validation (OPA, Kyverno, admission controllers).

Dashboards love Flux

No matter if you use one of the Flux UIs or a hosted cloud offering from your cloud vendor, Flux has a thriving ecosystem of integrations and products built on top of it and all have great dashboards for you.
