Its v2 line centered the tool on packaging Kubernetes configs as OCI artifacts, with signing through cosign and encryption through age. ### Adoption history Kustomizer's adoption story is tied to Kubernetes supply-chain and GitOps workflows rather than to a broad plugin ecosystem. The v2.2.0 release explicitly added Flux v2-compatible OCI artifacts, and the official Flux guide shows a workflow where CI publishes an artifact and Flux pulls and reconciles it inside the cluster. ### How it is used Users build and push Kubernetes manifests to OCI registries, tag and inspect artifacts, and apply those artifacts into clusters. The command reference and Flux guide emphasize registries such as GHCR, Docker Hub, ACR, ECR, GCR, Artifactory, and self-hosted registries. ### Why package nerds care Kustomizer is notable because it treats Kubernetes configuration like a package artifact: content-addressed, signable, encryptable, and transportable through standard OCI registry infrastructure. That makes it part of the broader move to use OCI registries for more than container images. ### Timeline - v2.0.0: Added OCI artifact distribution, push/pull, cosign verification, age encryption, and deployment from artifacts. - v2.2.0: Added Flux v2-compatible OCI artifacts and an official Flux deployment guide. ### Related projects - Kustomizer builds on Kubernetes server-side apply and overlaps operationally with Flux, kustomize, cosign, age, and OCI-compatible container registries. ### Sources - - - - ## Security Notes infrastructure mutation or orchestration signal. - **Geiger risk:** orange / medium - infrastructure mutation or orchestration signal ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** kustomizer - **Version Scheme:** 0 - **Revision:** 0 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Related links - [Cloud CLI packages](https://www.automicvault.com/pkg/cloud-clis/) - Belongs to a cloud or infrastructure command family. - [Package publisher tools](https://www.automicvault.com/pkg/package-publishers/) - Belongs to a package publishing or registry command family. - [Secret-risk packages](https://www.automicvault.com/pkg/secret-risk-packages/) - Has protected-tool coverage, approval-gate, or non-low Geiger security signals. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [go](https://www.automicvault.com/pkg/brew/go/) - Build dependency declared by Homebrew. - [kustomize](https://www.automicvault.com/pkg/brew/kustomize/) - Shares av.db curated category or tags: cli, cloud-infrastructure, configuration, kubernetes, kubernetes-configuration. - [glasskube](https://www.automicvault.com/pkg/brew/glasskube/) - Shares av.db curated category or tags: cli, cloud-infrastructure, kubernetes, package-manager. - [helm](https://www.automicvault.com/pkg/brew/helm/) - Shares av.db curated category or tags: cli, cloud-infrastructure, kubernetes, package-manager. - [kconf](https://www.automicvault.com/pkg/brew/kconf/) - Shares av.db curated category or tags: cli, cloud-infrastructure, configuration, kubernetes. - [kubetrim](https://www.automicvault.com/pkg/brew/kubetrim/) - Shares av.db curated category or tags: cli, cloud-infrastructure, configuration, kubernetes. - [naml](https://www.automicvault.com/pkg/brew/naml/) - Shares av.db curated category or tags: cli, cloud-infrastructure, configuration, kubernetes. - [tanka](https://www.automicvault.com/pkg/brew/tanka/) - Shares av.db curated category or tags: cli, cloud-infrastructure, configuration, kubernetes. - [timoni](https://www.automicvault.com/pkg/brew/timoni/) - Shares av.db curated category or tags: cli, cloud-infrastructure, kubernetes, package-manager. ## Combined YAML source View the package source record on GitHub.
