# Install kubeseal with Homebrew, apk, MacPorts, Nix, pacman, zypper, scoop Kubernetes controller and tool for one-way encrypted Secrets. Version 0.38.4 via Homebrew; verified 2026-07-04. Also installable with nix: nix profile install nixpkgs#kubeseal. ## Install ```sh sudo av install brew:kubeseal ``` ## Agent safety answer kubeseal transforms Kubernetes secrets and is tied to cluster secret-management workflows. - **Credential access:** Handles secret manifests and cluster public keys; input files may contain sensitive values. - **Remote mutation:** Does not usually mutate clusters directly, but output is intended for cluster application. - **Publish/artifact risk:** Can produce sealed secret artifacts committed or deployed to clusters. - **Recommended control:** Gate commands that read plaintext secret files or write deployable sealed secrets. - **Agent-use guidance:** Allow public-key fetches; require approval before processing plaintext secrets or writing manifests.

The project is split into a cluster-side controller/operator and the kubeseal CLI. kubeseal uses asymmetric cryptography to encrypt a Kubernetes Secret into a SealedSecret custom resource that only the target cluster's controller can decrypt. ### Adoption history kubeseal became a common companion tool for teams that wanted declarative Kubernetes deployments without introducing an external secret store into every workflow. Its release notes and README document distribution through Homebrew, MacPorts, Nixpkgs, Linux binaries, and controller manifests. ### How it is used A typical workflow creates or exports a Kubernetes Secret manifest, pipes it through kubeseal, commits the resulting SealedSecret YAML, and lets the in-cluster controller unseal it back into a normal Kubernetes Secret. ### Why package nerds care kubeseal is package-nerd interesting because the CLI is only half of the product: the packaged binary must line up with a CRD/controller deployed in the cluster. It also turned a security-sensitive Kubernetes workflow into a small Unix-friendly command-line transform. ### Timeline - 2026: The v0.38.1 release page listed controller installation YAML and kubeseal client binaries, including Homebrew instructions for macOS. ### Related projects - Related tools and patterns include Kubernetes Secrets, GitOps controllers such as Argo CD and Flux, external-secrets operators, SOPS, and cloud KMS-backed secret-management workflows. ### Sources - - ## Security Notes broad file, network, media, or database tool signal. infrastructure mutation or orchestration signal. - **Geiger risk:** orange / medium - broad file, network, media, or database tool signal - infrastructure mutation or orchestration signal ## Other Package-Manager Records - Nix - kubeseal: normalized package name match | nixpkgs package indexes: pkgs/by-name/ku/kubeseal/package.nix from https://api.github.com/repos/NixOS/nixpkgs/git/trees/master?recursive=1 - apk - kubeseal - 0.38.4-r1: normalized package name match | Alpine Linux edge package indexes: kubeseal from https://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz | A Kubernetes controller and tool for one-way encrypted Secrets | https://github.com/bitnami-labs/sealed-secrets - apk - kubeseal-doc - 0.38.4-r1: normalized package name match | Alpine Linux edge package indexes: kubeseal-doc from https://dl-cdn.alpinelinux.org/alpine/edge/testing/x86_64/APKINDEX.tar.gz | A Kubernetes controller and tool for one-way encrypted Secrets (documentation) | https://github.com/bitnami-labs/sealed-secrets - pacman - kubeseal - 0.35.0-2: normalized package name match | Arch Linux sync databases: kubeseal from https://geo.mirror.pkgbuild.com/extra/os/x86_64/extra.db.tar.gz | A Kubernetes controller and tool for one-way encrypted Secrets | https://github.com/bitnami-labs/sealed-secrets - zypper - kubeseal - 0.38.2-1.2: normalized package name match | openSUSE Tumbleweed package metadata: kubeseal from https://download.opensuse.org/tumbleweed/repo/oss/repodata/50b07339cb64c8ed4091bdbabddadc1ff5737b090e478818a195b40d8a3292861a879139b4a3987c31109699fde9fbf4a716367ddf4eef77da75f96e3193d6ed-primary.xml.zst | CLI for encrypting secrets to SealedSecrets | https://github.com/bitnami-labs/sealed-secrets - MacPorts - kubeseal: normalized package name match | MacPorts ports tree: sysutils/kubeseal/Portfile from https://api.github.com/repos/macports/macports-ports/git/trees/master?recursive=1 - Scoop - main/kubeseal: normalized package name match | Scoop official bucket manifest trees: bucket/kubeseal.json from https://api.github.com/repos/ScoopInstaller/Main/git/trees/master?recursive=1 ## Combined YAML source View the package source record on GitHub.
