FluxCD - With git as helm charts source

public This page describes how Flux CD interacts with Helm (see Helm). It shows how to create a helm chart and store it into a git repository. Then it describes how to configure flux, to observe this helm chart and deploy it to the kubernetes cluster.

In the root of the repository (not under clusters) run the following commands:

mkdir charts
cd charts
helm create nginx

Modify the nginx/values.yaml file as follows:

ingress:  
  enabled: true # changed  
  className: "nginx" # changed  
  annotations: {}  
  # kubernetes.io/ingress.class: nginx    
  # kubernetes.io/tls-acme: "true"  
  hosts:  
    - host: "" # changed  
      paths:  
        - path: /  
          pathType: ImplementationSpecific

Create a Helm Release resource file in clusters/my-clusters path. The filename could be nginx-helm-release.yaml. The contents are as follows:

apiVersion: helm.toolkit.fluxcd.io/v2  
kind: HelmRelease  
metadata:  
  name: nginx  
  namespace: default  
spec:  
  interval: 1m # how often flux cd should check for updates in the helm release file  
  chart:  
    spec:  
      chart: ./charts/nginx  
      sourceRef:  
        kind: GitRepository  
        name: flux-system # this repo was defined for flux cd at bootstrapping  
        namespace: flux-system  
      interval: 1m # how often flux cd should check for updates in the helm chart file

Commit the changes to Git by running the following commands:

git checkout -b nginx-helm
git add -A
git commit -m "Adding the Nginx Helm chart and creating the Flux CD Helm Release resource"
git push --set-upstream origin nginx-helm

• Copy the MR link, open the browser, paste the link, merge the MR and return back to the terminal.
• Force Flux CD to do a reconciliation by running the following command:

flux reconcile kustomization flux-system --with-source

Observe the Helm Release resource and the pods:

kubectl get helmrelease
kubectl get pods
