class path resource cannot be resolved to URL when running docker compose - spring-boot

Question

I am trying to create a docker-compose.yml since I have a lot of microservices to bootRun. It works properly when I run them one by one via gradle bootRun but encounter a lot of errors when doing docker-compose up
I want to use my local postgres database.
Here's my docker-compose.yml:
version: '3'
services:
redis:
image: redis:5.0.3-alpine
ports:
- '6379:6379'
rabbitmq:
image: rabbitmq:3.5.3-management
ports:
- "5672:5672"
- "15672:15672"
config-server:
network_mode: host
container_name: config-server
image: config-server:1.0.0-SNAPSHOT
customer-app:
network_mode: host
container_name: customer
image: customer:1.0.0-SNAPSHOT
environment:
- 'SPRING_DATASOURCE_URL=jdbc:postgresql://host.docker.internal:5432/demoapp?customer'
depends_on:
- config-server
restart: on-failure
authentication-app:
network_mode: host
container_name: authentication
image: authentication:1.0.0-SNAPSHOT
depends_on:
- config-server
restart: on-failure
admin-app:
network_mode: host
container_name: admin
image: admin:1.0.0-SNAPSHOT
environment:
- 'SPRING_DATASOURCE_URL=jdbc:postgresql://host.docker.internal:5432/demoapp?admin'
depends_on:
- config-server
restart: on-failure
Here's the error (1):

Answer 1

Assuming all other things work fine. In your Dockerfile
FROM openjdk:11.0.2-jdk-slim
VOLUME /tmp
RUN mkdir -p /data/sopie/your-project
COPY target/libs/*.jar /data/sopie/your-project/app.jar
EXPOSE 8081
ENTRYPOINT ["java","-jar","app.jar"]
