voting-gitops

GitOps manifests for the Docker voting app, structured with Kustomize.

Components

Service	Image	Role
vote	dockersamples/examplevotingapp_vote	Python web UI — accepts votes via Redis
redis	redis:alpine	In-memory queue for incoming votes
worker	dockersamples/examplevotingapp_worker	Drains Redis and writes results to Postgres
db	postgres:16	Persistent vote store
result	dockersamples/examplevotingapp_result	Node.js web UI — reads live results from db

Traffic enters via Traefik Ingress: vote.local → vote UI, result.local → results UI.

Secret Management

Postgres requires a password via a Kubernetes Secret named postgres-secret. The secret is not stored in this repo — it is applied manually to the cluster out of band before deploying:

kubectl create secret generic postgres-secret \
  --namespace voting \
  --from-literal=POSTGRES_PASSWORD=<your-password>

The db, worker, and result deployments all reference this secret via secretKeyRef. No plaintext credentials in git.
