I will share my Dockerfile

FROM adoptopenjdk/openjdk11
ADD ./build/libs/AppointmentsSystem-0.0.1-SNAPSHOT.jar app.jar
ENTRYPOINT exec java $JAVA_OPTS -Djava.security.egd=file:/dev/./urandom -jar /app.jar

and this is my build.gradle

plugins {
    id 'org.springframework.boot' version '2.2.1.RELEASE'
    id 'io.spring.dependency-management' version '1.0.8.RELEASE'
    id 'java'
}

group = 'com.sulimanLab'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = '11'

configurations {

    compileOnly {
        extendsFrom annotationProcessor
    }
}

repositories {
    mavenCentral()
}

wrapper {
    gradleVersion = "5.0"
}

dependencies {

    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation group: 'org.springframework.boot', name: 'spring-boot-starter-data-jpa'
    implementation group: 'org.postgresql', name: 'postgresql'


    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
    testImplementation('org.springframework.boot:spring-boot-starter-test') {
        exclude group: 'org.junit.vintage', module: 'junit-vintage-engine'
    }
    testImplementation 'io.projectreactor:reactor-test'
}

test {
    useJUnitPlatform()
}

and this is my docker-compose file

version: "3.7"
services:
  postgres:
    image: postgres:latest
    container_name: postgres
    volumes:
      - postgres-data:/var/lib/postgresql/data
    ports:
      - 5432:5432
    environment:
      - 'POSTGRES_ROOT_PASSWORD=admin'
      - 'POSTGRES_USER=postgres'
      - 'POSTGRES_PASSWORD=admin'
      - 'POSTGRES_DB=appointmentSystem'

  springbootapp:
    build: .
    environment:
      - 'spring.datasource.url=jdbc:postgresql://postgres:5432/appointmentSystem'
    ports:
      - 8080:8080
    depends_on:
      - postgres
volumes:
  postgres-data:

lastly this is my application.yml

spring:
  datasource:
    driver-class-name: org.postgresql.Driver
    url: jdbc:postgresql://localhost:5432/appointmentSystem
    username: postgres
    password: admin
  jpa:
    database-platform: org.hibernate.dialect.PostgreSQLDialect
    database: postgresql
    hibernate:
      ddl-auto: update
    properties:
      dialect: org.hibernate.dialect.PostgreSQLDialect

------------------

NOTE

when I build the jar file and run it alone it works, so I started to think that the problem came from dockerfile but I don't know, Please help.

Your postgres isn't running on localhost when deployed in docker, unless you are updating the Postgres container to include your jar, which I doubt. The URL should point to the name of the docker container containing Postgres. — M. Deinum

I don't think this is the problem, I expose the port on my local machine so it can be found when hitting localhost:5432, and the prove to that is I'm connecting to the database using DataGrip with url of localhost — suliman
– suliman, Commented Jan 6, 2020 at 11:17
That is from youyr local machine NOT from within the container. — M. Deinum
– M. Deinum, Commented Jan 6, 2020 at 11:17
I added this to spring boot environment environment: - 'spring.datasource.url=jdbc:postgresql://postgres:5432/appointmentSystem' and still I get this error "Caused by: org.postgresql.util.PSQLException: Connection to localhost:5432 refused." should not the environment overwrite the application.yml? — suliman
– suliman, Commented Jan 6, 2020 at 11:27
You should use SPRING_DATASOURCE_URL as name for the environment, spring.datasource.url isn't allowed as a name (AFAIK . is not allowed in names). — M. Deinum

Your application is trying to connect to localhost:5432. Instead you should connect to postgress service at postgres:5432

Your application is inside a container. Your local machine's localhost interface is different from the localhost interface inside your application's container.

I added this to spring boot environment environment: - 'spring.datasource.url=jdbc:postgresql://postgres:5432/appointmentSystem' and still I get this error "Caused by: org.postgresql.util.PSQLException: Connection to localhost:5432 refused." should not the environment overwrite the application.yml?
