FluxCD Capacitor

Prerequisites

Having a running Kubernetes cluster
Bootstrapped fluxcd
Knowledge on how to add charts/kubernetes resources with fluxcd
Usage of an ingress to make the webhook accessible from outside your network

Initial Setup

Create a new folder called capacitor inside the flux-system folder.
Update the kustomization.yaml file in flux-system with - capacitor
Next we will need 3 files inside the capacitor folder:

capacitor.yaml

apiVersion: kustomize.toolkit.fluxcd.io/v1
kind: Kustomization
metadata:
  name: capacitor
  namespace: flux-system
spec:
  targetNamespace: flux-system
  interval: 1h
  retryInterval: 2m
  timeout: 5m
  wait: true
  prune: true
  path: "./"
  sourceRef:
    kind: OCIRepository
    name: capacitor

ingress.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: capacitor
  namespace: flux-system
  annotations:
    cert-manager.io/cluster-issuer: domain-0-le-prod # use what you have configured for your ingress
    cert-manager.io/private-key-rotation-policy: Always
spec:
  ingressClassName: internal
  rules:
  - host: capacitor.${DOMAIN_0} # use what you have configured for your ingress
    http:
      paths:
      - pathType: Prefix
        path: /
        backend:
          service:
            name: capacitor
            port:
              number: 9000
  tls:
    - hosts:
      - capacitor.${DOMAIN_0} # use what you have configured for your ingress
      secretName: capacitor-tls-0 # use what you have configured for your ingress

kustomization.yaml

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
  - capacitor.yaml
  - ingress.yaml

Add The Repository

Go to your Reponsitories/oci directory and create this file.

capacitor-manifests.yaml

apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: OCIRepository
metadata:
  name: capacitor
  namespace: flux-system
spec:
  interval: 12h
  url: oci://ghcr.io/gimlet-io/capacitor-manifests
  ref:
    semver: ">=0.1.0"

Update the kustomization.yaml in oci to include - capacitor-manifests.yaml

Finishing Steps

Reoncile your cluster.
