How can I fix the Error of Docker-compose up exited with code 1

Question

I am beginner in Docker. I have a simple DockerFile and Docker-compose.yml files When I use docker-compose up, then it show an error which is exited with code 1 I do not know how can I fix it. my DockerFile:

FROM openjdk:8
ENV APP_HOME /home
RUN mkdir -p $APP_HOME
ADD target/spring-docker.jar $APP_HOME/spring-docker.jar
WORKDIR $APP_HOME
EXPOSE 8080
CMD ["java","-Dspring.data.mongodb.uri=mongodb://db:27017/","-jar","/home/spring-docker.jar"]

Docker-Compose:

version: '3.1'
services:
    spring-docker:
        build: .
        restart: always
        ports: 
            - "8080:8080"
        depends_on:
           - db
    db:
        image: mongo
        volumes:
            - ./data:/data/db
        ports:
            - "27017:27017"
        restart: always

The SpringBoot is based application along with it’s mongodb database.

Answer 1

docker may fail due to many things in the build process. To find the solution here is my advice

1. Type docker ps -la (to list all containers that exited with error code or failed to start
2. In the result, you should look out for the id of the container
3. Then check the logs using: docker logs <container_id>
