In our job listings implementation, we used the following code to determine the host for Elasticsearch:
host = 'localhost'if os.environ.get('ES_HOST'): host = os.environ.get('ES_HOST')print("ElasticSearch host: " + host)es = Elasticsearch(hosts=[host])

The implementation of the skills search also makes a similar change to allow us to change a default of localhost for our scraping microservice:
CONFIG = {'AMQP_URI': "amqp://guest:guest@localhost"}if os.environ.get('JOBS_AMQP_URL'): CONFIG[ ...
