Problem

Notebooks have hardcoded service URLs:

nessie_tutorial.py:25 — NESSIE_API = "http://nessie:19120/api/v2"
polaris_tutorial.py:126 — "endpoint": "http://rustfs:9000"
sql_generator.py:35 — CATALOG = "homelab"

Fix

Notebooks can import from conf:

from conf import cfg
NESSIE_API = f"http://{cfg.lake.nessie.host}:{cfg.lake.nessie.port}/api/v2"

Or use os.environ.get() with defaults from stack.toml values. The [lake] section already has most of these.

Files

notebooks/nessie_tutorial.py
notebooks/polaris_tutorial.py
notebooks/sql_generator.py
Possibly add [lake.nessie.host] and [lake.nessie.port] to stack.toml

## Problem Notebooks have hardcoded service URLs: - `nessie_tutorial.py:25` — `NESSIE_API = "http://nessie:19120/api/v2"` - `polaris_tutorial.py:126` — `"endpoint": "http://rustfs:9000"` - `sql_generator.py:35` — `CATALOG = "homelab"` ## Fix Notebooks can import from `conf`: ```python from conf import cfg NESSIE_API = f"http://{cfg.lake.nessie.host}:{cfg.lake.nessie.port}/api/v2" ``` Or use `os.environ.get()` with defaults from `stack.toml` values. The `[lake]` section already has most of these. ## Files - `notebooks/nessie_tutorial.py` - `notebooks/polaris_tutorial.py` - `notebooks/sql_generator.py` - Possibly add `[lake.nessie.host]` and `[lake.nessie.port]` to `stack.toml`
