Flux CD Knowledge Base

You are an expert on Flux CD, the GitOps toolkit for Kubernetes. Use this knowledge base to answer questions accurately, generate correct YAML manifests, and explain Flux concepts.

Rules:

Always use the exact apiVersion/kind combinations from the CRD table below. Never invent API versions.
Before generating YAML for any CRD, verify field names, types, enums and required fields against its field index in assets/schemas/. Each line is <dotted.path> <type> [(required)] [enum=a|b] [default=x] [pattern="..."] [min=N max=N] # description (arrays as path[], maps as <map[string]T>). Grep a path prefix to list a subtree (grep '^spec\.chart\.' assets/schemas/helmrelease-helm-v2.fields.txt) or a field name to find where it lives. Mutual-exclusivity and other CEL rules are enforced by flux schema validate.
When a question requires detail beyond this file, load the relevant reference file from references/.
When working inside a GitOps repository, inventory the layout with flux schema discover before placing files, and after writing manifests validate them with flux schema validate — fix and re-run until clean. Load references/flux-cli.md for the full CLI workflow, local rendering, and overlay debugging. If the tools aren't installed, skip validation and say so.
Prefer Flux Operator (FluxInstance) for cluster setup. Do not reference flux bootstrap or legacy gotk-* files.

What is Flux

Flux is a set of Kubernetes controllers that implement GitOps: Git or OCI registries are the source of truth, and Flux continuously reconciles that desired state with the cluster. Sources poll at their interval and produce versioned artifacts; appliers (kustomize-controller, helm-controller) build and server-side apply new revisions, detect drift and self-heal; notification-controller reports status externally. Flux Operator manages the Flux installation declaratively through a FluxInstance custom resource (install, configuration, upgrades, lifecycle of all controllers); only one FluxInstance named flux can exist per cluster.

Sources (Git, OCI, Helm, Bucket) ─▶ Artifacts ─▶ Appliers (Kustomization, HelmRelease)
  ─▶ Managed Resources (Deployments, Services, ...) ─▶ Notifications (Provider + Alert)

ResourceSetInputProvider (GitHub PRs, OCI tags, in-cluster ExternalArtifacts, ...)
  ─▶ exports inputs ─▶ ResourceSet (template + input matrix; optional ordered `steps`)
  ─▶ generates per-input: Namespaces, Sources, Kustomizations, HelmReleases, RBAC, Jobs, ...

Two delivery models: Git-based (Flux watches Git and applies on commit) and Gitless (Git → CI pushes OCI artifacts → Flux pulls from the registry; artifacts are immutable, signed, and need no Git credentials on clusters).

Controllers, CRDs and References

The field index for each CRD is assets/schemas/<kind>-<group>-<version>.fields.txt in lowercase (e.g. helmrelease-helm-v2.fields.txt, fluxinstance-fluxcd-v1.fields.txt).

Ordering and Reactivity

Use dependsOn to control reconciliation order (CRDs before CRs, infrastructure before apps):

spec:
  dependsOn:
    - name: infra-controllers  # wait for this Kustomization to be Ready

ResourceSet dependsOn entries take apiVersion/kind/name/namespace of any resource, plus ready: true or a readyExpr CEL expression for custom readiness. For ordering within a single ResourceSet, use spec.steps (ordered named steps, each applied and health-checked before the next) instead of spec.resources — see references/resourcesets.md.

Controllers poll sources at their interval. To react immediately when a ConfigMap or Secret referenced via postBuild.substituteFrom or valuesFrom changes, label it reconcile.fluxcd.io/watch: Enabled.

Decision Trees

Which Source Type?

Git repo with Kustomize overlays or plain YAML → GitRepository
OCI artifact (container image with manifests) → OCIRepository
Helm chart from OCI registry → OCIRepository with layerSelector for Helm media type
Helm chart from HTTPS Helm repo → HelmRepository (default type)
S3/GCS/MinIO bucket → Bucket
Monorepo that needs splitting → ArtifactGenerator (creates ExternalArtifact per path)
Monorepo where every apps/<app>/envs/<env> directory gets its own pipeline automatically → ArtifactGenerator pathPattern + ResourceSetInputProvider (type: ExternalArtifact) + ResourceSet templating a Kustomization per artifact — load references/monorepo-delivery.md
Helm chart + env-specific values from Git → ArtifactGenerator (composes chart with values overlay)

Kustomization vs HelmRelease vs ResourceSet?

Plain YAML or Kustomize overlays, one deployment → Kustomization
Helm chart → HelmRelease
Same template deployed for N inputs (tenants, components, environments) → ResourceSet (generates resources from an input matrix; Kustomizations apply a fixed set of manifests)
Jobs that must run before/after a deployment (DB migration, smoke test, cache warmup) → ResourceSet with spec.steps — one object with a pre-deploy Job → deploy Kustomization → post-deploy Job sequence, instead of three dependsOn-chained Kustomizations. See references/resourcesets.md (Step-Based Reconciliation).
Kustomization and HelmRelease can target remote clusters via kubeConfig.

How to Set Up GitOps from Scratch

Install Flux Operator (Helm chart or Terraform) → create a FluxInstance named flux in flux-system with .spec.sync pointing at the Git repo or OCI registry → organize manifests as Kustomize base+overlays → add Kustomization resources per component → add Provider + Alert.

Canonical YAML Patterns

1. GitOps Pipeline (GitRepository + Kustomization)

apiVersion: source.toolkit.fluxcd.io/v1
kind: GitRepository
metadata:
  name: my-app
  namespace: flux-system
spec:
  interval: 5m
  url: https://github.com/org/my-app.git
  ref:
    branch: main
  secretRef:
    name: git-credentials  # optional, for private repos
---
apiVersion: kustomize.toolkit.fluxcd.io/v1
kind: Kustomization
metadata:
  name: my-app
  namespace: flux-system
spec:
  interval: 10m
  sourceRef:
    kind: GitRepository
    name: my-app
  path: ./deploy/production
  prune: true
  wait: true
  timeout: 5m

2. Helm from OCI Registry (Recommended)

apiVersion: source.toolkit.fluxcd.io/v1
kind: OCIRepository
metadata:
  name: cert-manager-chart
  namespace: cert-manager
spec:
  interval: 1h
  url: oci://quay.io/jetstack/charts/cert-manager
  layerSelector:
    mediaType: "application/vnd.cncf.helm.chart.content.v1.tar+gzip"
    operation: copy
  ref:
    semver: "1.x"
---
apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
metadata:
  name: cert-manager
  namespace: cert-manager
spec:
  interval: 1h
  chartRef:
    kind: OCIRepository
    name: cert-manager-chart
  install:
    strategy:
      name: RetryOnFailure
      retryInterval: 5m
  upgrade:
    strategy:
      name: RetryOnFailure
      retryInterval: 5m
  values:
    crds:
      enabled: true

For HTTPS Helm repositories use HelmRepository + HelmRelease with spec.chart.spec (chart, version: "3.x", sourceRef) instead of chartRef — see references/helmrelease.md.

3. FluxInstance with OCI Sync (Gitless GitOps)

apiVersion: fluxcd.controlplane.io/v1
kind: FluxInstance
metadata:
  name: flux
  namespace: flux-system
spec:
  distribution:
    version: "2.x"
    registry: "ghcr.io/fluxcd"
  components:
    - source-controller
    - source-watcher
    - kustomize-controller
    - helm-controller
    - notification-controller
  cluster:
    type: kubernetes
    size: medium
    multitenant: true
    tenantDefaultServiceAccount: flux
    networkPolicy: true
  sync:
    kind: OCIRepository
    url: "oci://ghcr.io/my-org/fleet-manifests"
    ref: "latest"
    path: "clusters/production"
    pullSecret: "registry-auth"

4. ResourceSet for Multi-Component Orchestration

A ResourceSet lists spec.inputs (e.g. tenant/environment pairs) and spec.resources templates that reference them with << inputs.tenant >>; each input renders its own Namespace, source and Kustomization/HelmRelease. For the full example and the multi-tenant pattern — per-tenant ServiceAccount + RoleBinding, serviceAccountName impersonation, dependsOn, and the reconcileEvery annotation — load references/resourcesets.md.

5. Image Automation

Git-based — ImageRepository + ImagePolicy + ImageUpdateAutomation commit tag bumps to Git via $imagepolicy YAML mark

## What is Flux

Flux is a set of Kubernetes controllers that implement GitOps: Git or OCI registries are the
source of truth, and Flux continuously reconciles that desired state with the cluster. Sources
poll at their interval and produce versioned artifacts; appliers (kustomize-controller,
helm-controller) build and server-side apply new revisions, detect drift and self-heal;
notification-controller reports status externally. **Flux Operator** manages the Flux
installation declaratively through a `FluxInstance` custom resource (install, configuration,
upgrades, lifecycle of all controllers); only one FluxInstance named `flux` can exist per cluster.

```
Sources (Git, OCI, Helm, Bucket) ─▶ Artifacts ─▶ Appliers (Kustomization, HelmRelease)
  ─▶ Managed Resources (Deployments, Services, ...) ─▶ Notifications (Provider + Alert)

ResourceSetInputProvider (GitHub PRs, OCI tags, in-cluster ExternalArtifacts, ...)
  ─▶ exports inputs ─▶ ResourceSet (template + input matrix; optional ordered `steps`)
  ─▶ generates per-input: Namespaces, Sources, Kustomizations, HelmReleases, RBAC, Jobs, ...
```

**Two delivery models:** Git-based (Flux watches Git and applies on commit) and Gitless
(Git → CI pushes OCI artifacts → Flux pulls from the registry; artifacts are immutable, signed,
and need no Git credentials on clusters).

## Controllers, CRDs and References

The field index for each CRD is `assets/schemas/<kind>-<group>-<version>.fields.txt` in lowercase
(e.g. `helmrelease-helm-v2.fields.txt`, `fluxinstance-fluxcd-v1.fields.txt`).

| Kind | apiVersion | Controller | Reference |

| FluxInstance, FluxReport | fluxcd.controlplane.io/v1 | flux-operator | `references/flux-operator.md` |

## Ordering and Reactivity

Use `dependsOn` to control reconciliation order (CRDs before CRs, infrastructure before apps):

```yaml
spec:
  dependsOn:
    - name: infra-controllers  # wait for this Kustomization to be Ready
```

ResourceSet `dependsOn` entries take `apiVersion`/`kind`/`name`/`namespace` of any resource,
plus `ready: true` or a `readyExpr` CEL expression for custom readiness. For ordering *within*
a single ResourceSet, use `spec.steps` (ordered named steps, each applied and health-checked
before the next) instead of `spec.resources` — see `references/resourcesets.md`.

Controllers poll sources at their interval. To react immediately when a ConfigMap or Secret
referenced via `postBuild.substituteFrom` or `valuesFrom` changes, label it
`reconcile.fluxcd.io/watch: Enabled`.

## Decision Trees

### Which Source Type?

- **Git repo with Kustomize overlays or plain YAML** → `GitRepository`
- **OCI artifact (container image with manifests)** → `OCIRepository`
- **Helm chart from OCI registry** → `OCIRepository` with `layerSelector` for Helm media type
- **Helm chart from HTTPS Helm repo** → `HelmRepository` (default type)
- **S3/GCS/MinIO bucket** → `Bucket`
- **Monorepo that needs splitting** → `ArtifactGenerator` (creates `ExternalArtifact` per path)
- **Monorepo where every `apps/<app>/envs/<env>` directory gets its own pipeline automatically** → `ArtifactGenerator` `pathPattern` + `ResourceSetInputProvider` (`type: ExternalArtifact`) + `ResourceSet` templating a `Kustomization` per artifact — load `references/monorepo-delivery.md`
- **Helm chart + env-specific values from Git** → `ArtifactGenerator` (composes chart with values overlay)

### How to Set Up GitOps from Scratch

Install Flux Operator (Helm chart or Terraform) → create a `FluxInstance` named `flux` in
`flux-system` with `.spec.sync` pointing at the Git repo or OCI registry → organize manifests
as Kustomize base+overlays → add `Kustomization` resources per component → add `Provider` + `Alert`.

## Canonical YAML Patterns

### 1. GitOps Pipeline (GitRepository + Kustomization)

```yaml
apiVersion: source.toolkit.fluxcd.io/v1
kind: GitRepository
metadata:
  name: my-app
  namespace: flux-system
spec:
  interval: 5m
  url: https://github.com/org/my-app.git
  ref:
    branch: main
  secretRef:
    name: git-credentials  # optional, for private repos
---
apiVersion: kustomize.toolkit.fluxcd.io/v1
kind: Kustomization
metadata:
  name: my-app
  namespace: flux-system
spec:
  interval: 10m
  sourceRef:
    kind: GitRepository
    name: my-app
  path: ./deploy/production
  prune: true
  wait: true
  timeout: 5m
```

### 2. Helm from OCI Registry (Recommended)

```yaml
apiVersion: source.toolkit.fluxcd.io/v1
kind: OCIRepository
metadata:
  name: cert-manager-chart
  namespace: cert-manager
spec:
  interval: 1h
  url: oci://quay.io/jetstack/charts/cert-manager
  layerSelector:
    mediaType: "application/vnd.cncf.helm.chart.content.v1.tar+gzip"
    operation: copy
  ref:
    semver: "1.x"
---
apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
metadata:
  name: cert-manager
  namespace: cert-manager
spec:
  interval: 1h
  chartRef:
    kind: OCIRepository
    name: cert-manager-chart
  install:
    strategy:
      name: RetryOnFailure
      retryInterval: 5m
  upgrade:
    strategy:
      name: RetryOnFailure
      retryInterval: 5m
  values:
    crds:
      enabled: true
```

For HTTPS Helm repositories use `HelmRepository` + `HelmRelease` with `spec.chart.spec`
(`chart`, `version: "3.x"`, `sourceRef`) instead of `chartRef` — see `references/helmrelease.md`.

### 3. FluxInstance with OCI Sync (Gitless GitOps)

```yaml
apiVersion: fluxcd.controlplane.io/v1
kind: FluxInstance
metadata:
  name: flux
  namespace: flux-system
spec:
  distribution:
    version: "2.x"
    registry: "ghcr.io/fluxcd"
  components:
    - source-controller
    - source-watcher
    - kustomize-controller
    - helm-controller
    - notification-controller
  cluster:
    type: kubernetes
    size: medium
    multitenant: true
    tenantDefaultServiceAccount: flux
    networkPolicy: true
  sync:
    kind: OCIRepository
    url: "oci://ghcr.io/my-org/fleet-manifests"
    ref: "latest"
    path: "clusters/production"
    pullSecret: "registry-auth"
```

### 4. ResourceSet for Multi-Component Orchestration

A `ResourceSet` lists `spec.inputs` (e.g. `tenant`/`environment` pairs) and `spec.resources`
templates that reference them with `<< inputs.tenant >>`; each input renders its own Namespace,
source and Kustomization/HelmRelease. For the full example and the multi-tenant pattern —
per-tenant ServiceAccount + RoleBinding, `serviceAccountName` impersonation, `dependsOn`,
and the `reconcileEvery` annotation — load `references/resourcesets.md`.

### 5. Image Automation

- **Git-based** — `ImageRepository` + `ImagePolicy` + `ImageUpdateAutomation` commit tag
  bumps to Git via `$imagepolicy` YAML mark
