Next Flux release brings consolidated Git implementation
The Flux development team keeps on innovating. The latest release is Flux v0.37 and as always we encourage you all to upgrade for the best experience.
The biggest change is that the
gitImplementation field of
by source-controller and image-automation-controller is now deprecated.
Flux will effectively always use
go-git. This now supports all Git
servers, including Azure DevOps and AWS CodeCommit, which previously were
only supported by
libgit2. This is a big improvement and will help us focus
on making Flux work great with just one git implementation.
Here is our shortlist of features and improvements in the release:
- Support for bootstrapping Azure DevOps and AWS CodeCommit repositories
flux bootstrap git.
- Support cloning of Git v2 protocol (Azure DevOps and AWS CodeCommit) for
- Support force-pushing
- Allow a dry-run of
flux build kustomizationwith
--kustomization-file ./path/to/local/my-app.yaml. Using these flags, variable substitutions from Secrets and ConfigMaps are skipped, and no connection to the cluster is made.
- Use signed OCI Helm chart for kube-prometheus-stack.
Check out these new pieces of documentation:
💖 Big thanks to all the Flux contributors that helped us with this release!
Flux Roadmap Updates
Here’s an update from the Flux roadmap - we are rushing forward towards GA!
Starting with release v0.37, we started solidifying all required changes for the Bootstrap GA milestone targeted to Q1 2023. That release should include all major changes from a Git perspective that we want to ship for GA. Please make sure you upgrade as soon as possible and provide us with feedback, so we can work on it before the GA release.
Upcoming in the next release is a new feature for Image Automation
GitShallowClones. You can already check it out in the
recently published release candidate. If you are interested, you can
reach out via the PR or on Slack:
To benefit from our strong OCI integration, you might want to take a look at our latest blog post about how to verify the integrity of Helm charts stored as OCI artifacts.
Flagger 1.25 and 1.26 update to newest Gateway API
comes with support Kubernetes
v1beta1. For more details see the
Gateway API Progressive Delivery
Please note that starting with this version, the Gateway API v1alpha2 is
considered deprecated and will be removed from Flagger after 6 months.
Flagger 1.25.0 introduces a new deployment strategy combining Canary releases with session affinity for Istio. Check out the tutorial here. Furthermore, it contains a regression fix regarding metadata in alerts introduced in #1275.
Flux Subsystem for Argo
The team upgraded Flux Subsystem for Argo aka Flamingo to support Flux v0.37 and Argo CD v2.5.3, v2.4.17, v2.3.11 and v2.2.16.
The team has released Weave TF-controller v0.13.1 and recently updated its Helm chart to v0.9.3. In this version, the team started shipping the AWS Package for TF-controller. The AWS Package is an OCI Image which contains a set of Terraform primitive modules that you can use out-of-the-box to provision your Terraform resources by describing them as YAML.Please visit the package repository for more information: https://github.com/tf-controller/aws-primitive-modules.
GitOps Run continues to be enhanced as an easy way to get started with Flux and GitOps, and now includes yaml validation for both Flux and core Kubernetes resources. The Weave GitOps UI for Flux is now able to support multiple instances of Flux on the same cluster, for when resource isolation strategies are in place, so you can see the health of all controllers in the Flux Runtime view.
Then in the Enterprise edition of Weave GitOps, the Pipelines feature is now enabled by default to help you automatically promote applications through a series of environments, and GitOpsTemplates continue to be enhanced as a generic self-service capability for building out an Internal Developer Platform.
VS Code GitOps Extension
In its latest pre-release of
“Configure GitOps” workflow was introduced. It features a new unified
user interface for creating Source and Workload and for attaching Workloads
to Sources. It supports both Generic Flux and Azure Flux (Arc/AKS)
cluster modes. In Azure mode,
FluxConfig resources are created
automatically (this can be disabled if the user wants Generic mode
compatibility). Currently this feature is in the Extension Marketplace
pre-release channel and supports
If you want a user-friendly UI for working with every type of Source and Workflow please check out this pre-release and give the team feedback!

Upcoming Events 📆
We are happy to announce that we have a number of events coming up in December- tune in to learn more about Flux and GitOps best practices, get to know the team and join our community.
The Flux project continues in active development with the addition of OCI configuration planned in the GA roadmap. Another Flux advancement has been the creation of the new VSCode Extension which provides a convenient interface to Flux that can help reduce friction moving between editor and terminal, alleviating the headache of context switching overloading developer focus.
Flux maintainer Kingdon Barrett will demonstrate the pre-release of Flux’s new OCI features and a convenient way to access them while they remain in pre-release so you can provide the feedback that is needed by Flux maintainers to make this feature a success!
Flux Bug Scrub
Our Flux Bug Scrubs still are happening on a weekly basis and remain one of the best ways to get involved in Flux. They are a friendly and welcoming way to learn more about contributing and how Flux is organised as a project.
The next dates are going to be:
We are flexible with subjects and often go with the interests of the group or of the presenter. If you want to come and join us in either capacity, just show up or if you have questions, reach out to Kingdon on Slack.
We really enjoyed this demo of the k3d git server recently. It’s a local Git server that runs outside of Kubernetes, to support offline dev in a realistic but also simple way that does not depend on GitHub or other hosted services.

Flux Project Facts
We are very proud of what we have put together. We want to reiterate some Flux facts - they are sort of our mission statement with Flux.
- 🤝 Flux provides GitOps for both apps or 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.
- 🤖 Just 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).
- 🔩 Flux 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, and all CI workflow providers.
- 🔒 Flux is 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.
- ☸️ Flux works with any Kubernetes and all common Kubernetes tooling: Kustomize, Helm, RBAC, and policy-driven validation (OPA, Kyverno, admission controllers) so it simply falls into place.
- 🤹 Flux 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.
- 📞 Flux alerts and notifies: Flux provides health assessments, alerting to external systems and external events handling. Just “git push”, and get notified on Slack and other chat systems.
- 👍 Users trust Flux: Flux is a CNCF Graduated project and was categorised as “Adopt” on the CNCF CI/CD Tech Radar (alongside Helm).
- 💖 Flux has a lovely community that is very easy to work with! 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.
