py2neo连接拒绝，而docker组成

我想运行一个Django的应用程序，它使用py2neo库连接到neo4j数据库。 它在我的本地机器上正常运行。 但是当我试图使用docker-compose得到它时，我一次又一次地出现了错误。

这是我的docker-compose.yml文件

version: '2' services: db: image: postgres neo4j: image: neo4j ports: - "7474:7474" - "7687:7687" volumes: - ./db/dbms:/data/dbms web: build: . command: python manage.py runserver 0.0.0.0:8000 volumes: - .:/code ports: - "8000:8000" depends_on: - db - neo4j links: - neo4j 

Dockerfile：

 FROM python:3 FROM neo4j:3.1 ENV PYTHONUNBUFFERED 1 RUN mkdir /code WORKDIR /code ADD requirements.txt /code/ RUN pip install -r requirements.txt ADD . /code/ ADD startneo.sh /startneo.sh CMD ["/start.sh"] 

views.py

 import os import json # Create your views here. from py2neo import Graph, authenticate from bottle import get,run,request,response,static_file graph = Graph(password='neo4j') @get("/") def get_index(): return static_file("index.html", root="static") @get("/graph") def get_graph(self): print("i was here" ) print("graph start") results = graph.run( "MATCH (m:Movie)<-[:ACTED_IN]-(a:Person) " "RETURN m.title as movie, collect(a.name) as cast " "LIMIT {limit}", {"limit": 10}) print("graph run the run") nodes = [] rels = [] i = 0 for movie, cast in results: #print("i am here") nodes.append({"title": movie, "label": "movie"}) target = i i += 1 for name in cast: print(name) actor = {"title": name, "label": "actor"} try: source = nodes.index(actor) except ValueError: nodes.append(actor) source = i i += 1 rels.append({"source": source, "target": target}) return {"nodes": nodes, "links": rels} @get("/search") def get_search(): try: q = request.query["q"] except KeyError: return [] else: results = graph.run( "MATCH (movie:Movie) " "WHERE movie.title =~ {title} " "RETURN movie", {"title": "(?i).*" + q + ".*"}) response.content_type = "application/json" return json.dumps([{"movie": dict(row["movie"])} for row in results]) @get("/movie/<title>") def get_movie(title): results = graph.run( "MATCH (movie:Movie {title:{title}}) " "OPTIONAL MATCH (movie)<-[r]-(person:Person) " "RETURN movie.title as title," "collect([person.name, head(split(lower(type(r)),'_')), r.roles]) as cast " "LIMIT 1", {"title": title}) row = results.next() return {"title": row["title"], "cast": [dict(zip(("name", "job", "role"), member)) for member in row["cast"]]} 

我无法把networking和运行

 docker-compose up 

总是抛出以下错误

我不知道如何解决这个问题。
