Java Software Engineer Bootcamp

Participant lab guides for the Java Software Engineer six-week bootcamp (no solution keys) from Innovation In Software.

Early-career developers build full-stack enterprise Java skills — from JVM foundations through Spring, Kafka, React, PostgreSQL, DevOps, and a production-style capstone.

Audience	Early-career developers preparing for enterprise Java roles
Format	6 weeks · theory + hands-on labs
Through-line project	Evolving Customer Management Platform (CRM) across Labs 1–52
Repository	Innovation-In-Software/bc-sw-engineer-java-participant
Cohort env	Shared AWS host 100.22.136.97 · see FINAL-SETUP-README

---

Start here

1. Read Final Lab Environment Setup — shared host, Postgres / Kafka / k3s / GHCR
2. Read Participant Setup README — what you install on the laptop vs what the instructor provides
3. Skim Week 1 IDE conventions — IntelliJ IDEA Community (primary) and VS Code (optional)
4. Complete Lab 0 — Development Environment Setup on your laptop (Windows · macOS)
5. Use the Lab Index for Labs 1–52

All labs run from your laptop. Credentials and kubeconfigs are handed out by the instructor — they are not stored in this Git repository.

Training environment (final for this cohort)

Everything heavy runs on one shared AWS server (us-west-2, IP 100.22.136.97). Students connect out from IntelliJ (or optional VS Code) on their laptop. Full write-up: labs/FINAL-SETUP-README.md.

Shared service	Endpoint	Notes
PostgreSQL 17	100.22.136.97:5432	DB bootcamp; per-student role + schema
Apache Kafka 4.0	100.22.136.97:9092	Single shared broker
Kubernetes (k3s)	https://100.22.136.97:6443	Per-student namespace; Traefik on :80/:443
CI / images	GitHub Actions + GHCR	—

You install on the laptop	Instructor provides (Google Sheet / Docs)
IntelliJ IDEA Community (primary) · optional VS Code	Credentials row (studentNN + password)
JDK 21, Maven 3.9.x, Git	JDBC: jdbc:postgresql://100.22.136.97:5432/bootcamp?currentSchema=studentNN
Node 22 (before Week 4)	Kafka bootstrap 100.22.136.97:9092
kubectl (before Week 5)	Kubeconfig studentNN.yaml
GitHub + Copilot (as assigned)	GHCR / org guidance

Confirmed stack: PostgreSQL + GitHub Actions + k3s (kubectl + Traefik Ingress).

Weeks	What you need from the env
0–3	Laptop tools only
4	PostgreSQL + Kafka (+ Node 22 for React)
5–6	Above + k3s namespace + GHCR + GitHub Actions

Deploy path (Week 5+): build image → push GHCR → kubectl apply into your namespace.

Reachability requires the class IP allowlist (or instructor VPN). Never commit passwords, kubeconfigs, or .env files.

Clone and navigate

git clone https://github.com/Innovation-In-Software/bc-sw-engineer-java-participant.git
cd bc-sw-engineer-java-participant

1. Open labs/FINAL-SETUP-README.md
2. Read labs/_PARTICIPANT-FILE-GUIDE.md once (which file when)
3. Complete Lab 0 (Windows · macOS) — includes Git identity
4. Work under ~/java-bootcamp or %USERPROFILE%\java-bootcamp
5. For each later module: open module-NN/README.md (Week 1) → exercises → one OS how-to → LAB-N-GUIDE.md. Lab 1 Step 0 creates your private java-bootcamp GitHub repo.

Do not treat labs/.../solution/ as your working project unless a lab says otherwise.
