X-Definitions

Enable fluxcd addon to use these X-definitions

• helm helps to deploy a helm chart from everywhere: git repo / helm repo / S3 compatible bucket.

• kustomize helps to deploy a kustomize style artifact.

Note

• In this Fluxcd Addon, there are five controllers to be installed by default

DEFINITION NAME	DEFINITION TYPE	DEFINITION DESCRIPTION	SUPPORT CONTROLLER
config-helm-repository	ComponentDefinition	Config information to authenticate helm chart repository	helm-controller
helm	ComponentDefinition	helm release is a group of K8s resources from either gitrepository or helm repo	helm-controller
kustomize	ComponentDefinition	kustomize can fetching, building, updating and applying Kustomize manifests from git repo	kustomize-controller

• Source controller

  • The source-controller is a Kubernetes operator, specialised in artifacts acquisition from external sources such as Git, Helm repositories and S3 buckets. The source-controller implements the source.toolkit.fluxcd.io API and is a core component of the GitOps toolkit.
  • 

• Image (metadata) reflector controller

  • This is a controller that reflects container image metadata into a Kubernetes cluster. It pairs with the image update automation controller to drive automated config updates.

• Image automation controller

  • This controller automates updates to YAML when new container images are available.
  • Its sibling, image-reflector-controller, scans container image repositories and reflects the metadata in Kubernetes resources. This controller reacts to that image metadata by updating YAML files in a git repository, and committing the changes.

• kustomize-controller

  • The kustomize-controller is a Kubernetes operator, specialized in running continuous delivery pipelines for infrastructure and workloads defined with Kubernetes manifests and assembled with Kustomize.
  • 

• helm-controller

  • The helm-controller is a Kubernetes operator, allowing one to declaratively manage Helm chart releases. It is part of a composable GitOps toolkit and depends on source-controller to acquire the Helm charts from Helm repositories.
  • The desired state of a Helm release is described through a Kubernetes Custom Resource named HelmRelease. Based on the creation, mutation or removal of a HelmRelease resource in the cluster, Helm actions are performed by the operator.
