Lab 06-02: External Dependencies

Module: Nextcloud (it-stack-nextcloud)
Duration: 45–90 minutes
Machines: 2–3
Difficulty: Intermediate

Objective

Integrate Nextcloud with external services: PostgreSQL (lab-db1), Redis, and network-level connectivity.

Prerequisites

• Lab 06-01 passing
• PostgreSQL accessible at lab-db1:5432
• Redis accessible at lab-db1:6379
• Network connectivity between nodes

Environment

Uses docker/docker-compose.lan.yml — connects to external database and cache services.

Test Script

ests/labs/test-lab-02.sh

Success Criteria

• Database connection established and schema created
• Redis cache connection working
• Service performs correctly with external data store
• Data persists across restarts

Steps

1. Ensure lab-db1 PostgreSQL and Redis are running
2. make test-lab-02 or run ests/labs/test-lab-02.sh
3. Verify database tables created
4. Test restart persistence

Notes

Requires Phase 1 Foundation (PostgreSQL, Redis) to be running.
