I just found that running consul directly on the host machine can discover services through apisix DNS. Is there anything special that needs to be paid attention to when deploying consul in docker?

See if this doc helps: https://docs.api7.ai/apisix/how-to-guide/service-discovery/consul-integration

Both Apisix and consul are started in Docker in that doc.
