Auto-Updating the Git Commit Status

First of all we need to generate a new Auth Token with repo cababilities wich will be set as a secret in kubernetes

Generate an auth token

Check all the repo attributes in https://github.com/settings/tokens/new

Save the result token as a secret in Kubernetes

kubectl create secret -n flux-system generic github-token --from-literal=token=${NEW_TOKEN}

Add an Alert Provider

flux create alert-provider github-instavote \
    --type github \
    --address="https://github.com/${GITHUB_USER}/instavote.git" \
    --secret-ref=github-token \
    --export | tee clusters/staging/github-instavote-staging-alert-provider.yaml

Verify the outputs and providers:

---
apiVersion: notification.toolkit.fluxcd.io/v1beta1
kind: Provider
metadata:
  name: github-instavote
  namespace: flux-system
spec:
  address: https://github.com/${GITHUB_USER}/instavote.git
  secretRef:
    name: github-token
  type: github

Commit and propagate the changes

git add clusters/staging
git commit -m "feat: Add github-instavote Alert Provider"
git push origin HEAD:refs/heads/main

Wait for the Reconciliation to take place and verify the alert-provider is visible:

flux get alert-providers

Add Alerts

Now that we have our gate to GitHub we can start adding Alerts to the commit messages. Keep in mind that only the Kustomizations will be able to send information as they are the only ones containing a SHA:

cd flux-infra

for kustomize in redis vote worker; do
	flux create alert ${kustomize}-staging \
	  --provider-ref=github-instavote \
	  --event-severity=info \
	  --event-source "Kustomization/${kustomize}-staging" \
	  --export | tee clusters/staging/${kustomize}-staging-alert.yaml
 done

Commit, Publish and Reconcile the Changes

git add clusters/staging
git commit -m "feat: Add Alerts for Kustomizations"
git push origin HEAD:refs/heads/main

# Reconcile sources and check for alerts
flux reconcile source git flux-system
flux get alerts

Verify the Alerts

Have fun and change the setting for any part of the vote, redis or worker application and you'll see the magic in place ;)
