Unable to run two docker containers with docker-co

Question

I'm trying to run two web services in 2 separate containers, but unable to run them both at the same time. Separately they both work.

My project structure is this:

/
- docker-compose.yml
- Dockerfile
- pom.xml
- src/
- ... other spring boot web service folders and files
- Pirmas/
  -Dockerfile
  -app.py
  -docker-compose.yml (it is not used when running both services)

One web service is in the main directory the other is in the directory "Pirmas". I try to run docker composer from the base folder where the spring boot service is. I use the command "docker-compose up --build -d".

However, after building only the spring boot web service is launched and when I check the logs of the flask web service it says "python: can't open file 'app.py': [Errno 2] No such file or directory"

My spring boot service Dockerfile:

FROM maven:3.6-jdk-8 AS build  

WORKDIR /code

COPY src /code/app/src
COPY pom.xml /code/app
RUN mvn -f /code/app/pom.xml clean install

FROM openjdk:8
COPY --from=build /code/app/target/SpringWebServiceToDoList-0.0.1-SNAPSHOT.jar SpringWebServiceToDoList-0.0.1-SNAPSHOT.jar
EXPOSE 5000
CMD ["java","-jar","SpringWebServiceToDoList-0.0.1-SNAPSHOT.jar"]

My docker-compose.yml file in the same directory:

version: '3'

services:
  springboot-docker-compose-app-container:
    build: .
    ports:
      - "80:5000"
    depends_on:
    - friendservice
    volumes:
    - .:/code
    networks:
    - mynet
  friendservice:
    build: ./Pirmas
    command: python app.py
    ports:
    - 5000:5001
    networks:
    - mynet

networks:
    mynet:

My Dockerfile in the flash web service:

FROM python:3

WORKDIR /code

COPY requirements.txt ./
RUN pip install -r requirements.txt

Lastly the docker-compose.yml which I assume is not used(from the flask web service directory "Pirmas"):

web:
  build: .
  command: python app.py
  ports:
    - "80:5000"
  volumes:
    - .:/code

What I tried:

I tried removing the volumes. Tried different paths in docker-compose.yml like python ./Pirmas/app.py

I would be grateful for any help or ideas.

Thank you.

EDIT

I'm having a similar issue when trying to launch another project, but this time a Spring Boot application.

The project structure:/
    - docker-compose.yml
    - Dockerfile
    - pom.xml
    - src/
    - ... other spring boot web service folders and files
    - rest-bookstore/
      -Dockerfile
      -rest
        -src
        -target
          -gs-rest-service-0.1.0.jar

The old Dockerfile of the first spring boot service is the same the new one is:

FROM maven:3.6.0-jdk-8-alpine
COPY rest /rest
WORKDIR /rest
RUN mvn clean package
CMD java -jar target/gs-rest-service-0.1.0.jar --server.port=5000

And the docker-compose.yml

version: '3'

services:
  springboot-docker-compose-app-container:
    build: .
    ports:
      - "80:5000"
    depends_on:
    - friendservice
    volumes:
    - .:/code
    networks:
    - mynet
  friendservice:
    build: ./rest-bookstore
    volumes:
    - ./rest-bookstore:/rest
    ports:
    - 5000:5001
    networks:
    - mynet

networks:
    mynet:

I get error:

Unable to access jarfile target/gs-rest-service-0.1.0.jar

And I don't know why since in the new dockerfile it copies the whole rest directory

Answer 1

Your friendservice doesn't have app.py inside. You should whether copy it so your Dockerfile looks like

FROM python:3

WORKDIR /code

COPY requirements.txt ./
RUN pip install -r requirements.txt

COPY app.py ./

Or you can attach volume in your docker-compose.yml so it looks like

...
  friendservice:
    build: ./Pirmas
    command: python app.py
    ports:
    - 5000:5001
    volumes:
    - ./Pirmas:/code
    networks:
    - mynet
...
