[Chapter 12 - docker-compose]: set explicit version number for Elasticsearch & Kibana images
Building the docker-compose in chapter 12 results in pulling latest images error for either the elasticsearch and the kibana images. You have to be explicit on the version number for both of them. As of today, it works for elasticsearch:5.6, kibana:5.5.2

Chapter 6 example does not behave as described in the book.
On docker-compose up and a curl -I http://{DOCKER_HOST}/holdings as suggested on page 141, the curl-call bails out with a AttributeError: module 'holdings.queries_cached' has no attribute 'Holdings'.
I would expect it to trace the 3 calls tried.
Chapter 6 cache Example not working
I'm testing the example of cache method, but the request is always executed
`
import requests
import logging
from cachetools import cached, TTLCache
class MarketDataClient(object):
logger = logging.getLogger(__name__)
cache = TTLCache(maxsize=10, ttl=5*60)
base_url = 'http://market-data:8000'
def _make_request(self, url):
response = requests.get(
f"{self.base_url}/{url}", headers={'content-type': 'application/json'})
return response.json()
@cached(cache)
def all_prices(self):
MarketDataClient.logger.warning("Making request to get all_prices")
return self._make_request("prices")
def price(self, code):
return self._make_request(f"prices/{code}")
`
Here is the output of the containers:

Holdings is getting the request all the times. Any clue?
Broken builds
MacOS Mojave (version 10.14.3)
Docker Desktop Community (version 2.0.3.0)
Just go for example to chapter 7/feature directory, and run docker-compose up --build

Looks like it is failing to resolve the environment variables.
But there are lots of other nameko related errors/deprecation notices etc too.
Chapter 6 - `docker-compose up` fails
Trying to build the example using docker-compose up fails on macOS 13, citing an error for a class uri 'gevent' invalid or not found.
I'm not sure if this is an error with the example or with my system, but if anyone has any clue as to what I can fix to get this to work I would be very grateful for the help.
