我有两个简单的图像：

#Angular image
FROM node:12.2.0

WORKDIR /app

ENV PATH /app/node_modules/.bin:$PATH

COPY package.json /app/package.json
RUN npm install
RUN npm install -g @angular/cli@7.3.9

COPY . /app

CMD ng serve 

＆

# Java spring (REST) image
FROM openjdk:8-jdk-alpine
VOLUME /tmp
COPY ./target/api-0.0.1-snAPSHOT.jar app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","app.jar"]

还有我的docker-compose：

version: '3'

services:
  web_app_speech:
    image: web_app_speech
    restart: always
    ports:
      - "4300:4200"
    depends_on: 
      - api_speech_docker
  api_speech_docker:
    image: api_speech_docker
    ports:
      - "8080:8080"
    restart: always

$> docker ps

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES

我可以从本地主机：8080访问我的REST API，并且可以从本地主机：4300访问我的Web应用程序，但是当我尝试执行从web_app到rest_api的调用时，出现以下错误：

OPTIONS http://api_speech_docker:8080/speech net::ERR_NAME_NOT_RESOLVED

如果您需要更多日志，请告诉我，我不知道该如何解决！
