Scale setup script to bootstrap N simulated Edge instances

[amalbet]

Summary

• Add --edges N flag to setup.sh (default: 1, max: 9) to bootstrap N independent Edge instances
• Generate per-edge config directories from the template with unique UUIDs, service.pid values, and apikeys
• Generate docker-compose.override.yml with N edge services on unique ports (edge i → 8{i}80/8{i}85)
• Register each edge in Odoo DB with unique apikey written to both config file and database
• Fix existing bug: template had apikey="DEMO_API_KEY" but setup.sh hardcoded a different value
• Extend verification to check all N edges for Scheduler + RRD4j connectivity

Closes #64

Changes

• setup.sh: New helper functions (generate_apikey, generate_edge_config, generate_compose_override, generate_uuid, sedi), argument parsing for --edges N, loops for DB registration/verification/restart
• .gitignore: Ignore generated config-edge*/ dirs and docker-compose.override.yml

Bug fixes included (discovered during integration testing)

Critical: Backend Odoo UID was wrong (odooUid=1 → odooUid=2)

The backend's Metadata/Odoo.config had odooUid=I"1" — the Odoo __system user, which cannot make XML-RPC calls. This caused Access Denied errors on every edge metadata sync, making edges connected but invisible in the OpenEMS UI. Fixed to odooUid=I"2" (the admin user). This affects all deployments, not just multi-edge.

Edge device INSERT missing active=true

Odoo's ORM has an implicit active=True filter — records without it are treated as "archived" and hidden from all queries. The raw SQL INSERT for edge registration didn't set this field, so edge1/edge2 were invisible despite being fully connected at the backend level. Also added name_number for proper display ordering.

Port 8075 not exposed

The B2B REST API port (used by the billing engine for meter discovery) was missing from the docker-compose backend port mappings.

Setup script hardening

• SIGPIPE in generate_apikey: tr </dev/urandom | head -c 20 exits 141 with pipefail; fixed with subshell set +o pipefail
• Odoo password race condition: Replaced sleep 5 with a 12-attempt retry loop — Odoo takes 15-30s to accept XML-RPC on first boot
• psql default database: Added -d postgres for pg_database catalog query (no odoo database exists by default)
• Admin user-role assignment: Insert into openems_device_user_role so edges appear in the UI

Port scheme

Edge	Felix Console	Websocket
edge0	localhost:8080	localhost:8085
edge1	localhost:8180	localhost:8185
edge2	localhost:8280	localhost:8285
...	8{i}80	8{i}85

Test plan

• ./setup.sh (no flag) — bootstraps 1 edge, identical behavior to before
• ./setup.sh --edges 3 — generates 3 config dirs, 3 services in override, 3 DB entries
• Verify all edges visible in OpenEMS UI (not just edge0)
• Verify each edge connects to backend (check logs for Edge.Websocket)
• Verify no Access Denied errors in backend logs
• Verify config filenames match service.pid in all generated configs
• Verify --edges 0, --edges 10, --edges abc are rejected with clear errors
• Verify template dir openems-edge/config.d/ is not modified
