Nginx错误失败（111：连接被拒绝），而连接到上游，docker-compose nodejs

Question

我试图构建多个服务，并用Nginx反向代理它们。

所以service1是：

http://api/service1(nginx)=>docker(http://service1:4001/)=>express(http://localhost:4000)

这是我第一次从头开始尝试nginx，我被困住了，我无法从http://localhost:80/service1或http://api/service1访问任何服务。你认为这是开发和生产的微服务体系结构的一个良好开端吗？

我对我的docker里面的网络也有疑问，放那个网络还是让默认的docker网络准确吗？

（所有的容器运转良好）；

FROM node:latest

RUN mkdir /src
WORKDIR /src

COPY package.json /src/package.json
RUN npm install

COPY . /src/
EXPOSE 4000

FROM nginx

COPY nginx.conf /etc/nginx/nginx.conf

我正在尝试访问http://localhost:80/service1/，这通常会让我访问http://service1:4001

但我得到了一个错误：

[错误]7#7:*2connect()在连接到上游时失败（111：连接被拒绝），客户端:172.23.0.1，服务器：

我还试图访问http://api/service1/(nginx.conf中定义为server_name)，但没有任何响应或ping。
