Running pages initdb fails in our docker container as it attempts to connect to the DEFAULT_SOLR_URL as defined in ckan/lib/search/common.py:29. Passing in our production.ini does not appear to update the solr values.

Very naively I've tried these two initialisations and neither works:

RUN ckan -c ${APP_DIR}/production.ini pages initdb
# and then bluntly:
RUN CKAN_SOLR_URL=http://solr-headless:8983/solr ckan -c ${APP_DIR}/production.ini pages initdb

Is there something I'm missing, or is this the pages initdb method failing to appropriately use the config?
