history

Project history and usage

qbec is a Jsonnet-based command-line tool for generating and applying environment-specific Kubernetes objects across clusters and namespaces.

Project history

qbec was developed to generate and manage Kubernetes objects across multiple clusters or namespaces, with configuration specialized for a selected target environment. It uses Jsonnet as its data-templating and composition language.

The project explicitly positions itself near kubecfg and ksonnet while providing an application-oriented workflow for initializing configuration, rendering manifests, comparing them with a cluster, and applying or deleting resources. It is maintained in Splunk's GitHub organization.

Adoption history

qbec is distributed as cross-platform release binaries and through Homebrew and Nix. Its placement in the Splunk GitHub organization and dedicated documentation site provide it with a vendor-maintained home while retaining an Apache-licensed open-source workflow.

How it is used

A project is initialized around `qbec.yaml`, environment definitions, and Jsonnet components and parameters. Operators select an environment, render or validate objects, compare desired state with a cluster, and then apply or delete resources.

qbec is useful when several clusters or namespaces share a common configuration model but need target-specific parameters. Kubernetes access follows the operator's normal cluster context and credentials rather than a qbec-specific credentials file.

Why package nerds care

qbec represents the Jsonnet branch of Kubernetes configuration tooling: configuration remains programmable and composable while a CLI provides environment selection, diffing, application, and deletion. Package users value it as a focused alternative to template-heavy or abandoned Jsonnet-era tools.

Timeline

  • Origins: qbec was created around Jsonnet-based, multi-environment Kubernetes configuration.
  • Project adoption: The project moved under or is maintained by Splunk and gained a dedicated documentation site.
  • Distribution: Cross-platform release binaries and package-manager installations became available.

Related projects

  • Jsonnet is qbec's configuration language.
  • Kubernetes is the deployment target.
  • kubecfg and ksonnet are related Jsonnet-based Kubernetes configuration tools named by qbec's official repository.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
