What this command does. cub installer is a released, open-source plugin for the cub CLI. cub installer setup pulls a catalog package and writes its Kubernetes files locally. It does not apply those files to a cluster; use kubectl, Argo CD, or Flux for delivery. The generated scripts stop before doing any work when the plugin or kustomize is missing.

New to cub? Install the cub CLI first. You can pull and render public catalog packages without an account. Commands that save or change ConfigHub data require you to sign in.

UNOFFICIAL/EXPERIMENTAL. This page defines the five main terms in the catalog. It also explains the four stages from a Helm source to an operated ConfigHub variant.

The five words

WordWhat it isWhere it lives
RecipeThe source of a render: chart, version, values, named bases, and declared routing intent.The repo (recipes/) and the installer package.
RenderingRunning the recipe once to create exact Kubernetes objects.A tool run such as cub installer setup, outside ConfigHub Server.
Render recordThe evidence for one render. It joins the render intent, rendered objects, checksums, and related receipts.The repo (data/helm-render-intents/ and revision files).
Base variantOne named way to render a chart, such as default, no-crds, existing-secret, or ha. The --base option selects it.The package (bases/<name>) and, after upload, a root ConfigHub Space.
Derived variantA ConfigHub Space cloned from an uploaded base for an environment, region, or customer. It records its upstream base and does not rerender Helm.ConfigHub.

In one sentence: a recipe renders into a base variant, a base variant becomes derived variants, and promotions carry reviewed changes between them.

The source and intent record

Every maintained base needs a record that explains where its objects came from and which choices produced them. We call this the source and intent record.

This is a role, not one file format. For Helm, the record is a HelmRenderIntent. For AICR, it is the recipe and bundle receipts. Existing OCI and plain YAML use records that name their source digest or checksums, object inventory, remaining inputs, prerequisites, checks, and later transformations. Today, that information may live in a source Unit, Space metadata plus a committed receipt, or a generated base-variant record.

The record should let a new reader answer four questions:

  1. What source produced these objects?
  2. Which values or choices were used?
  3. What must exist or run before delivery?
  4. Which checks and receipts support the result?

All maintained examples should answer those questions. Chart-specific records for hooks, CRDs, Secrets, setup jobs, and target facts are added when the configuration needs them; they are not copied into examples where they do not apply.

An arbitrary upload does not gain facts that ConfigHub cannot know. Generic checks can be attached automatically. A source adapter or review must supply the source details and any chart-specific lifecycle work; otherwise the missing information is recorded as a gap.

The four stages

StageNameWhat happensThe word
F1 · sourceRecipeRecord the chart, version, values, and routing intent.recipe
F2 · renderBase variantCreate the exact objects. The render record binds the inputs to that output.base variant, render record
F3 · routesPrerequisites and routesRecord hooks, CRDs, Secrets, target facts, and other work outside ordinary objects.routing intent
F4 · operateDerived variantsClone, edit, review, promote, deliver, and observe the configuration.derived variant

Rendering is not deployment. F2 produces configuration files. F4 can deliver reviewed objects to live infrastructure. A base variant Space therefore has no Target until you choose to deliver it.

How this guide uses action words

WordMeaning here
renderCreate Kubernetes objects from a recorded source and its inputs.
inspectRead objects or evidence. Inspection alone does not prove a claim.
testRun a defined command or procedure.
verifyCompare a result with a recorded expectation, digest, or object set.
reviewDecide whether a known change or result is acceptable.
proveProduce an inspectable receipt for one limited claim.
applySend desired Kubernetes objects to a cluster.
deliverGive reviewed objects to the controller or apply path that sends them to a cluster.
observeRead the live result after delivery.
promoteMove a reviewed change to another environment while keeping its allowed local differences.
routeRecord who performs work outside ordinary Kubernetes objects, such as a hook or prerequisite.

The word check is broad. The guides use a more exact word when the difference matters.

The same objects, three other ways of seeing them

If you think in plain Helm: the recipe is your pinned chart and values. A base variant is the output of helm template for one values choice, kept as reviewable files. A derived variant gives one environment its own recorded version of those objects and keeps its changes through upgrades.

If you think in Kustomize: a base variant plays the role of a base, and a derived variant plays the role of an overlay. The base is already rendered rather than patched at build time. The derived variant is a ConfigHub Space with revisions, gates, and an upstream link rather than a directory convention.

If you think in source objects: the chart source can be one small YAML record containing the repository, chart, version, and values. The catalog keeps that record in the repo today. Rendering it produces the base variant. ConfigHub manages the resulting objects without running Helm again.

Where each thing is, today

When you browse a ConfigHub org, you see the rendered Units, derived Spaces, revisions, and links from F2 through F4. The recipe and render record remain in this repo and the package. Each uploaded Space has an installer-record Unit that identifies the package that produced it.
