docker-compose error when creating MySQL database container - mysql

Question

I have the following docker-compose.yml and Dockerfile in my Spring Boot app but when I run docker-compose up -d, I get the following error:
"failed to solve: rpc error: code = Unknown desc = failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount967315702/Dockerfile: no such file or directory"
As I use Windows10, I think I need some tweaks related to the WORKDIR, etc. I have WSL where Docker installed). But even I tried different combinations, I have not managed to fix the problem.
Here is the docker-compose.yml and Dockerfile in my root project folder (springboot-backend):
docker-compose.yml: I am not sure about
version: "3.8"
services:
mysqldb:
image: mysql:5.7
restart: unless-stopped
env_file: ./.env
environment:
- MYSQL_ROOT_PASSWORD=$MYSQLDB_ROOT_PASSWORD
- MYSQL_DATABASE=$MYSQLDB_DATABASE
ports:
- $MYSQLDB_LOCAL_PORT:$MYSQLDB_DOCKER_PORT
volumes:
- db:/var/lib/mysql
app:
depends_on:
- mysqldb
build: ./springboot-backend
restart: on-failure
env_file: ./.env
ports:
- $SPRING_LOCAL_PORT:$SPRING_DOCKER_PORT
environment:
SPRING_APPLICATION_JSON: '{
"spring.datasource.url" : "jdbc:mysql://mysqldb:$MYSQLDB_DOCKER_PORT/$MYSQLDB_DATABASE?useSSL=false",
"spring.datasource.username" : "$MYSQLDB_USER",
"spring.datasource.password" : "$MYSQLDB_ROOT_PASSWORD",
"spring.jpa.properties.hibernate.dialect" : "org.hibernate.dialect.MySQL5InnoDBDialect",
"spring.jpa.hibernate.ddl-auto" : "update"
}'
volumes:
- .m2:/root/.m2
stdin_open: true
tty: true
volumes:
db:
Dockerfile:
FROM maven:3.8.2-jdk-8
WORKDIR /springboot-backend
COPY . .
RUN mvn clean install
CMD mvn spring-boot:run
.env file:
MYSQLDB_USER=root
MYSQLDB_ROOT_PASSWORD=******
MYSQLDB_DATABASE=employee_management_system
MYSQLDB_LOCAL_PORT=3307
MYSQLDB_DOCKER_PORT=3306
SPRING_LOCAL_PORT=6868
SPRING_DOCKER_PORT=8080
Any idea?
Here is folder structure:

Docker compose yaml try to build springboot-backend but there is no such directory in the same path of compose yaml. Just simply you can move docker-compose yaml to outside of springboot-backend project folder.
