Flux Legacy Retirement plans. Flux at KubeCon and lots of Ecosystem updates!" url: /blog/2022/10/september-2022-update/ tags: [monthly-update] resources: - src: "**.{png,jpg}" title: "Image #:counter" --- 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](/blog/2022/09/august-2022-update/). It's the beginning of October 2022 - let's recap together what happened in September - it has been a lot! ## News in the Flux family ### Flux v0.34.0 and 0.35.0 bring OCI improvements {{< imgproc flux Resize 500x >}} {{< /imgproc >}} [Flux v0.35](https://github.com/fluxcd/flux2/releases/tag/v0.35.0) and [Flux v0.34](https://github.com/fluxcd/flux2/releases/tag/v0.34.0) landed in September. They bring tons of improvements, especially in the area of OCI. We encourage everyone to upgrade for the best experience. Please note: there are breaking changes: The Flux controller logs have been aligned with the Kubernetes structured logging. For more details on the new logging structure please see: [fluxcd/flux2\#3051](https://github.com/fluxcd/flux2/issues/3051). Here is a quick summary of what you can look forward to in terms of features and improvements: - Verify OCI artifacts signed by Cosign (including `keyless` - currently still experimental and only supporting GCP and GHCR) with [OCIRepository.spec.verify](/flux/components/source/ocirepositories/#verification). Note this supports contextual login, but not insecure registries. - Allow pulling Helm charts dependencies from HTTPS repositories with mixed self-signed TLS and public CAs. - Allow pulling Helm charts from OCI artifacts stored at the root of AWS ECR. - Allow running bootstrap for insecure HTTP Git servers with `flux bootstrap git --allow-insecure-http --token-auth`. - Improve health checking for global objects such as `ClusterClass`, `GatewayClass`, `StorageClass`, etc. - The controllers and the Flux CLI are now built with Go 1.19. - Allow pulling artifacts from an in-cluster Docker Registry over plain HTTP with [`OCIRepository.spec.insecure`](/flux/components/source/ocirepositories/#insecure). - Allow defining OCI sources for non-TLS container registries with `flux create source oci --insecure`. - Enable contextual login when publishing OCI artifacts from a Cloud VM using `flux push artifact --provider=aws|azure|gcp`. - Prioritise static credentials over OIDC providers when pulling OCI artifacts from container registries on multi-tenant cluster. - Reconcile Kubernetes Class types (`ClusterClass`, `GatewayClass`, `StorageClass`, etc) in a dedicated stage before any other custom resources like `Clusters`, `Gateways`, `Volumes`, etc. - When multiple SOPS providers are available, run the offline decryption methods first to avoid failures due to KMS unavailability. - Add finalizers to the notification API to properly record the reconciliation metrics for deleted resources. - Publish the Flux install manifests as OCI artifacts on GitHub and DockerHub container registries under `fluxcd/flux-manifests`. For more information on OCI and Cosign support please see the [Flux documentation](/flux/cheatsheets/oci-artifacts/#signing-and-verification). It took us six months to debate, design and implement OCI support in Flux. Big thanks to all the Flux contributors that helped us reach this milestone! ### Flux Legacy (v1) Retirement Plan Thanks to so many of you who have been migrating to the latest Flux version, often in conversation with us. We appreciate your enthusiasm for the increased capabilities of Flux. In October 2020 we put Flux Legacy and Helm operator into maintenance mode (cf [flux\#3320](https://github.com/fluxcd/flux/issues/3320) and [helm-operator\#546](https://github.com/fluxcd/helm-operator/issues/546)). Back then we promised to continue to support them for 6 months once we reached feature-parity across all former feature sets, and instead we have offered extended support for over a year. We [reached parity in March 2021](/blog/2021/03/march-2021-update/#feature-parity---what-is-this) and announced [stable APIs in July 2021](/blog/2021/07/july-2021-update/#from-now-on-flux-apis-will-be-stable). Since then we added OCI support and many other modern features to Flux v2. Thanks to you not only for migrating, but also for adding yourselves to the latest Flux [adopters page](/adopters/)! We really appreciate it. Your work has brought down the number of support requests for legacy Flux to 5% of all volume in the past year. We will archive Flux Legacy in November this year. If you still need migration help, there are still [free migration workshops](https://bit.ly/FluxMigrationSurvey), or reach out for paid support to one of the companies [listed here](/support/#commercial-support). Some recent prompts for this include: - Some of the Flux v1 dependencies are pinned to EOL versions, which cannot be upgraded without causing regressions or a cascading amount of changes to the codebase. - All Kubernetes dependencies are pinned within version v1.21. That version already reached end-of-life support upstream. Thanks for joining us on this journey of building Flux. [Please give Flux a star](https://github.com/fluxcd/flux2)! ### Flux Ecosystem #### Flux Subsystem for Argo The team is happy to announce that [Flux Subsystem for Argo (FSA)](https://github.com/flux-subsystem-argo/flamingo) is now on-par with ArgoCD regarding supported versions. FSA now provides all versions supported by ArgoCD. The project will provide security updates based on ArgoCD v2.2 and v2.3, and for the active ArgoCD version (currently v2.4), FSA will support them, starting from v2.4.12. For Flux compatibility, FSA will be tested against every release of future Flux versions. {{< imgproc fsa Resize 900x >}} {{< /imgproc >}} #### Weave GitOps Weaveworks just released version [v0.9.6](https://github.com/weaveworks/weave-gitops/releases/tag/v0.9.6) for Weave GitOps. There are a lot of great new features that have been released in the last month. First, it is continuing the trend of being a feature rich Flux UI by adding support for Flux Providers and Alerts. When you click on the user icon you are then taken to a screen that contains those objects. As a platform operator, you can easily understand where events are being sent. On the kustomization and helm release detail pages there is now a tab to check your dependencies for those objects. The `dependsOn` is a powerful feature in Flux and now you can easily see these visualised within the application. We're also making it easy to navigate from these graphs to relevant objects in a near future release. {{< imgproc wg-dependson Resize 900x >}} {{< /imgproc >}} In addition, the team added numerous improvements to `gitops run` our live coding environment. Now you can run the command against an empty folder and it will generate a `kustomization.yaml` file and give you a live connection between that working directory and the cluster you are connected to. The team is full steam ahead on the next set of features for the run experience. ##### Terraform Controller The Weave GitOps team is continuing to improve our ecosystem of controllers with the latest release of the tf-controller [v0.12.0](https://github.com/weaveworks/tf-controller/releases/tag/v0.12.0). The notable features in this release are: custom backend support, interop with Notification controller, and support human readable plan output in `ConfigMap`. This is all new: - Enable custom backends for Terraform - Support `backendConfigsFrom` for specifying backend configuration from Secrets - Add a parameter for specifying max gRPC message size, default to 4MB - Implement `force-unlock` for `tfstate` management - Fix the initialization status - Recording events to support Flux notification controller - Support specifying targets for plan and apply - Add node selector, affinity and tolerations for the runner pod - Add volume and volumeMounts for the runner pod - Add file mapping to map files from Secrets to home or workspace directory - Fix Plan prompt being overridden by the progressing message - Support storing human-readable plan output in a ConfigMap Learn more at the [following blog post "How to GitOps Your Terraform"](/blog/2022/09/how-to-gitops-your-terraform/), by Priyanka Ravi & Daniel Holbach. ##### Weave GitOps Enterprise The Weave GitOps Enterprise continues to build on top of the OSS feature set with its latest [v0.9.5 release](https://web.archive.org/web/20230528041532/https://docs.gitops.weave.works/docs/releases/). First, the team has added a new add application button with support for both Kustomizations and Helm Releases. This makes it super easy to add the relevant Flux primitives to get your applications loaded onto the cluster(s) of your choice. Workspaces were added as well. This makes it super easy to manage multi-tenancy on Weave GitOps Enterprise. It is built on top of Flux's tenancy model with a lot of extra flexibility and power. For example, all of your workspaces can be defined in one or more files. We then have a simple CLI command that will generate all of the necessary YAML for you. This includes advanced features such as policies to ensure full compliance within the tenant. You can define which repositories your users can use as well as which clusters applications can be deployed to. To learn more about this feature check out the [documentation](https://web.archive.org/web/20230921131521/https://docs.gitops.weave.works/docs/workspaces/multi-tenancy/). You can also now define pipelines and environments for Helm Charts. This will allow your application teams to see how things are rolled out across dev, staging, and production environments; or however you choose to define your environments. There will be a lot of continued efforts in this area so stay tuned. Your engineering teams are able to see policy violations for applications across clusters. Policy sets can be used by platform operators to define in one place whether policies are for auditing purposes or should be blocked by the admission controller. The team built out a profile for making it easy to set up policy dashboards using the ELK stack. Platform operators now have greater flexibility when configuring the same policy with different values for different clusters. #### VS Code GitOps Extension A lot of great features have been added to the extension, most notably support for OCI and Azure. Please see the recent [blog post in our ecosystem category](/blog/2022/09/gitops-without-leaving-your-ide/) for more details. ## 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. ### Recent Events (ICYMI) 📺 We feel blessed to have such a big community of users, contributors and integrators and so many are happy to talk about their experiences.

We really enjoyed this [demo of the k3d git server](https://www.youtube.com/watch?v=hNt3v0kk6ec) 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. ## In other news ### New Flux Project Members: Batuhan Apaydın and Rashed Kamal We are very excited to be able to announce two new Flux project members this month. Batuhan Apaydın, Senior Software Engineer at Trendyol, has been [helping out quite a bit](https://github.com/fluxcd/community/issues/242) in the OCI discussions and wrote a blog post explaining [how to manage Kyverno policies as OCI artifacts](/blog/2022/08/manage-kyverno-policies-as-ocirepositories/) recently. We are very glad to have him in our community and there's more OCI awesomeness and blog posts planned. Rashed Kamal, Staff Engineer at VMware, [joined us in September as well](https://github.com/fluxcd/community/issues/239). His interests include OCI, where he contributed to the RFC too. On top of that he fixed a number of issues in Flux. Thanks for all of that and for being part of the team! {{< imgproc rashedkvm Resize 400x >}} {{< /imgproc >}} ### 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: [NovaID](https://novaid.vn/).

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: - We simplified the build process of the website. We are on a very recent version of the Docsy theme again! - Our [Bootstrap Cheatsheet](/flux/cheatsheets/bootstrap/) now contains instructions on how to enable notifications for third party controllers. - [Flux End-To-End documentation](/flux/flux-e2e/) was updated to reflect recent changes. - We added a lot of new videos to [the Flux Resources page](/resources/). - Many small improvements and fixes across the entire site and docs. Thanks a lot to these folks who contributed to docs and website: Stefan Prodan, Kingdon Barrett, Arhell, Paulo Gomes, Max Jonas Werner, Vanessa Abankwah, Santosh Kaluskar, Batuhan Apaydın, Stacey Potter, Bang Nguyen, Sven Nebel, Aurel Canciu, David Harris, Gustaf Lindstedt, Simo Aleksandrov and annaken. ## 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. 1. 🤖 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). 1. 🔩 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. 1. 🔒 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. 1. ☸️ 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. 1. 🤹 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. 1. 📞 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](https://github.com/fluxcd/notification-controller/blob/main/docs/spec/v1beta1/provider.md). 1. 👍 Users trust Flux: Flux is a CNCF Incubating project and was categorised as \"Adopt\" on the [CNCF CI/CD Tech Radar](https://radar.cncf.io/2020-06-continuous-delivery) (alongside Helm). 1. 💖 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. ## Over and out If you like what you read and would like to get involved, here are a few good ways to do that: - Join our [upcoming dev meetings](/community/#meetings) on 2022-10-06 or 2022-10-12. - Talk to us in the \#flux channel on [CNCF Slack](https://slack.cncf.io/) - Join the [planning discussions](https://github.com/fluxcd/flux2/discussions) - And if you are completely new to Flux, take a look at our [Get Started guide](/flux/get-started/) and give us feedback - Social media: Follow [Flux on Twitter](https://twitter.com/fluxcd), join the discussion in the [Flux LinkedIn group](https://www.linkedin.com/groups/8985374/).
