Upgrading to elasticsearch 8 on docker-compose local installations. If you are upgrading to this release, make sure you delete your old search index otherwise you'll get errors in ES about an old index. Delete by running docker exec -it newsblur_web ./manage.py reindex_stories --reindex and docker exec -it newsblur_web ./manage.py reindex_feeds
