Tilt + Helm Demo (Fictional)

This is a public, fictional, Tilt-first demo that showcases fast local iteration while keeping Helm in the deploy path. It is intentionally generic and safe to publish.

What’s Included

• Quarkus web service with /dummy and /files endpoints
• PostgreSQL running in-cluster
• LocalStack (S3) running in-cluster for S3-compatible object storage
• Helm chart for the app
• Tiltfile that wires everything together + DB seeding + S3 bucket init hook

Quickstart

Prereqs

• Docker
• Kubernetes local cluster (kind or k3d)
• Tilt
• kubectl
• Helm

Run

# From the repo root
tilt up

Then open:

• http://localhost:8080/dummy — Postgres-backed message
• http://localhost:8080/files — S3 file listing (empty initially)

Upload a file to S3:

curl -X POST http://localhost:8080/files/hello.txt \
  -H "Content-Type: application/octet-stream" \
  --data-binary "Hello from S3!"
curl http://localhost:8080/files

How It Works

1. Tilt builds the app image (web).
2. Tilt applies tilt/postgres.yaml to run Postgres.
3. Tilt applies tilt/localstack.yaml to run LocalStack (S3).
4. Tilt installs the Helm chart in helm/demo-web.
5. Tilt seeds the database by running tilt/seed-db.sh.
6. LocalStack automatically creates the S3 bucket via init hooks.
7. The app connects to Postgres and S3 (LocalStack) and serves /dummy and /files.
