Connect spring-boot with MongoDB database using Docker.

mongo.yml file configuration:-

version: '3'
services:

   mongodb:
      image: mongo:latest
      restart: on-failure
      volumes:
        - $HOME/Documents/udaanDb:/data/db
      environment:
        MONGO_INITDB_ROOT_USERNAME: root
        MONGO_INITDB_ROOT_PASSWORD: example
      ports:
        - 27017:27017

Now run the mongo.yml file. To run the file:

docker-compose -f <file-location> up -d

# Now check for the mongo dependency in pom.xml file. If the below dependency is not there add it.

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

• That’s all in dependency for now. Let’s configure the application-properties file now.

server.port = 8080
spring.data.mongodb.uri=mongodb://root:example@0.0.0.0:27017/?authSource=admin&authMechanism=SCRAM-SHA-1
spring.data.mongodb.database=udaanUserDb
