However this works fine:

elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.5.1
    container_name: elasticsearch
    hostname: elasticsearch
    environment:
      - discovery.type=single-node
    env_file:
      - ./.env
    ulimits:
      memlock:
        soft: -1
        hard: -1
    ports:
      - "9200:9200"
      - "9300:9300"
    networks:
      - flex
  kibana:
    image: docker.elastic.co/kibana/kibana:7.5.1
    container_name: kibana
    hostname: kibana
    ports:
      - "5601:5601"
    networks:

this works for me just fine. I can't recreate your issue

[Anderssorby]

I got it working with your config. I might have forgotten to rebuild the images or something.
