Part 12 of this project

Deploy

Prepare Gearcart Market for production hosting.

Goal

This snapshot advances Gearcart Market by teaching you to prepare Gearcart Market for production hosting.

Every numbered folder is a complete app. Run this stage independently, then compare it with the previous folder.

Prerequisites

Use JDK 17+, Maven, and Docker for MySQL stages.

Port 8084 must be free. Copy .env.example before database stages.

  • JDK 17+
  • Maven
  • Docker from part 4 onward

Concepts

Production needs HTTPS cookies, a strong secret, env-only database URLs, built assets, and forced migrations.

Thymeleaf renders server HTML; Spring Security owns the session; JPA repositories persist catalog and orders.

Walkthrough

Review deploy docs; never commit secrets.

Read the example, then open the matching snapshot. The repository includes validation, CSRF, and the surrounding structure.

./mvnw -DskipTests package
java -jar target/gearcart-*.jar --server.port=${PORT:-8084}

Run and verify

Enter 12-Deploy, copy .env.example, start Docker MySQL, and run ./mvnw spring-boot:run on port 8084.

Open http://127.0.0.1:8084. From data lessons onward, Ada and Grace use password123.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-spring-ecommerce.git
cd fcc-spring-ecommerce/12-Deploy
cp .env.example .env
./mvnw spring-boot:run

Troubleshooting

If sessions vanish after deploy, check HTTPS cookie and domain settings.

For database failures, confirm Docker and the gear_NN name. Never commit .env, target/, or secrets.

  • Read the first exception first
  • Rebuild assets after Tailwind class changes
  • Never commit secrets

Try this

List every secret that must live only in the host environment.

Test a happy path and one invalid or unauthorized request.

  • Make one small change
  • Test it in the browser
  • Compare with the next snapshot only after it works
