SOLVED Accessing MongoDB from spring boot container

Question

I'm trying to connect Mongodb which is installed on my windows from a spring boot container but I'm facing :

2022-02-26 00:08:52.868  INFO 1 --- [localhost:27017] org.mongodb.driver.cluster               : Exception in monitor thread while connecting to server localhost:27017

Here is my docker-compose file:

version: '3'
services:
  bootloader:
    build: ./
    container_name: project
    ports:
      - "8080:8080"
    links:
      - host.docker.internal
    volumes:
      - /tmp/

Here is my application.properties file:

spring.data.mongodb.database=IODATABSE
spring.data.mongodb.port=27017
#spring.data.mongodb.host=localhost
spring.data.mongodb.authentication-database=admin
logging.level.org.springframework.data.mongodb.core.MongoTemplate= DEBUG
#spring.data.mongodb.authentication-database=admin
spring.data.mongodb.host=host.docker.internal
#spring.data.mongodb.port=27017
spring.data.mongodb.password=PASSWORD
spring.data.mongodb.username=USERNAME

So I'm wondring if there is a way to solve this, and Thank you

Answer 1

I solved it by this:

 environment:
      - SPRING_DATA_MONGODB_URI=mongodb://host.docker.internal:27017

Added Mongodb Java Driver on MongoDB pom.xml:

<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongodb-driver-core</artifactId>
    <version>4.5.0</version>
</dependency>

and on my parent pom.xml

    <dependency>
        <groupId>org.mongodb</groupId>
        <artifactId>mongodb-driver-core</artifactId>
        <version>3.8.2</version>
    </dependency>

Refering to MongoDB Documentation on Java drivers: https://docs.mongodb.com/drivers/reactive-streams/
