Project cross-post from the Flux blog by Daniel Holbach

As the Flux family of projects and its communities are growing, we strive to inform you each month about what has already landed, new possibilities which are available for integration, and where you can get involved. Read our last update here.

It’s the beginning of July 2022 – let’s recap together what happened in June – it has been a lot!

News in the Flux family

A lot of work culminated in the 0.31 release series, where we landed at Flux v0.31.3. You can look forward to the following set of important fixes and documentation improvements:

Flux Ecosystem

Since the rewrite of Flux as a set of targeted controllers, we believe it has become a lot easier to extend Flux to whatever you need it to do. If you check out the Flux Ecosystem page you can see a lot of very useful extensions, products and tools you might find useful.

In this section of our monthly update, let’s go through what happened in the ecosystem.


The team around terraform-controlle started the new development cycle towards v0.10.0. They introduced a new feature that supports resource inventory inside a Terraform object so that other controllers like an external drift detector, or a cost estimator would be able to leverage it.

For the coming v0.10.0 release, they will focus on performance improvements so that the controller will handle large numbers of objects better.

Weave GitOps

The GitOps Dashboard is continuing to evolve and we have added a bunch of new features with the release of v0.9.0. You can now pause and resume automations and sources within the UI. The team also added a new yaml tab to each object page so you can see the full detail of the object on the cluster.

They have also added support for displaying custom metadata. It is super easy to use and enables you to put relevant information such as a description of the object or hyperlinks to metrics dashboards.

They have also improved the detail and graph views in the application. They were only able to show a subset of kubernetes objects that were created by Kustomizations and Helm Releases. You can now get a full view of all of the objects that were created.

The team is turning their attention to a new feature at the moment and are looking for people willing to participate as early beta users. They are building a new feature in Weave GitOps that will change the way you can interact with Kubernetes as you build out your system. The idea is to reduce friction as much as possible and get live feedback. Once you are done then you will be able to easily transition the workload management over to GitOps via Flux.

They are excited about this feature and would appreciate people that are willing to test early versions so they build the best possible solution that solves problems. If you are interested please sign up here and they will reach out to you via email when they are ready to start the beta test.

New additions to the Flux Ecosystem

We are very pleased to recognise KubeVela as part of the Flux Ecosystem: it integrates Flux well for Helm Chart delivery and GitOps, and provides multi-cluster capabilities.

Recent & Upcoming Events

It’s important to keep you up to date with new features and developments in Flux and provide simple ways to see our work in action and chat with our engineers.

Upcoming Events

Flux maintainer Somtochi Onyekwere at KCD Africa 2022 – Virtual

Screenshot shows Kubernetes Comunity Days Virtual Event featuring #KCDAFRICA homepage

Somtochi Onyekwere has been contributing to Kubernetes and Flux for a long while already. We are very grateful to have her as part of the Flux maintainers team.

At the keynote at Kubernetes Community Days Africa 2022 – Virtual, she will be speaking about her experience going from contributor to project maintainer.

Join her and all the other speakers on July 7 & 8. Register here.

Recent Events (ICYMI) 📺

GitOps Days 2022

GitOps Days was a big celebration of everything we achieved as the Flux community in the past years. It was a big get-together of its maintainers, GitOps practitioners, cloud service vendors and our big community to talk about everything that’s possible today.

If you check out the schedule on its website you get a good idea of the high quality talks and workshops that happened there.

If you should have missed it, don’t despair – the GitOps Days team is working on publishing separate videos and dedicated videos very soon. In the meantime you can still hit the “Register” button on the website to get a link to the recordings of the two days!

Thanks to everyone who attended and organised the event – we had a fabulous time!

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. If folks have other Flux-related topics and want a friendly audience to present for interest and feedback, we are always open to ideas and will host, come pitch us with your Flux talks while we iterate weekly issue queue hygiene!

People writing/talking about Flux

We love it when you all write about Flux and share your experience, write how-tos on integrating Flux with other pieces of software or other things. Give us a shout-out and we will link it from this section! ✍

Alexander Block: Multiple Environments with Flux and Kluctl

Multiple Environments - fun graphic with ice cream - dev test staging and prod

Alexander Block is not only the author of Kluctl, but has joined us as a Flux contributor as well. If you are new to Kluctl, it says on its website that

Kluctl is the missing glue to put together large Kubernetes deployments.

It allows you to declare and manage small, large, simple and/or complex multi-env and multi-cluster deployments.

Kluctl does not have cluster-side dependencies and works out of the box.

Check out the new blog post to get an idea how Kluctl helps you wire up multiple environments.

News from the Website and our Docs

Flux Adopters shout-out

We are very pleased to announce that the following adopters of Flux have come forward and added themselves to our website: AutopsMediaMarktSaturnJ.B. HuntQuickTableSenseLabs and TraefikLabs.

If you have not already done so, use the instructions here or give us a ping and we will help to add you. Not only is it great for us to get to know and welcome you to our community. It also gives the team a big boost in morale to know where in the world Flux is used everywhere.

More docs and website news

We are constantly improving our documentation and website – here are a couple of small things we landed recently:

Thanks a lot to these folks who contributed to docs and website: Stefan Prodan, Ihor Sychevskyi, Ed Briggler, Max Jonas Werner, Paulo Gomes, xiexiong, Chrliey Haley, Hidde Beydals, Jianbo Sun, Kevin Fritz, LXM, Philip Laine, Poor12, Somtochi Onyekwere, Soulé Ba, Vincent Palmer, Vincent Van der Kussen, Wiliam Brode, netthier.

In particular we would like to thank Ihor Sychevskyi again who took on fixing small UI glitches all over the place – especially on mobile the site should work a lot better now!

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.

  1. 🤝 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.
  2. 🤖 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).
  3. 🔩 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.
  4. 🔒 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.
  5. ☸️ 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.
  6. 🤹 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.
  7. 📞 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.
  8. 👍 Users trust Flux: Flux is a CNCF Incubating project and was categorised as “Adopt” on the CNCF CI/CD Tech Radar (alongside Helm).
  9. 💖 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.
