Dokerfile

FROM openjdk:8-jdk-alpine
ADD target/spring-mongo.jar spring-mongo.jar
ENTRYPOINT ["java","-jar","spring-mongo.jar"]

application.properties

spring.data.mongodb.host=mymongodb
spring.data.mongodb.port=27017
spring.data.mongodb.database=mongo
spring.data.mongodb.repositories.enabled=true

docer-compose.yml

version: "3"
services:
  mymongodb:
    image: mongo:latest
    container_name: "mymongodb"
    ports:
      - 27017:27017
  spring-mongo:
    image: spring-mongo:1.0
    container_name: spring-mongo
    ports:
      - 8080:8080
    links:
      - mymongodb

At the point you get that error, is MongoDB actually started up; if you wait, do you get further startup messages from the database after that exception? Or, if you run docker-compose up -d, get the exception, wait 30-60 seconds, and try that same command again, does it start up? — David Maze

In your docker-compose.yml, you are only linking your spring boot application with your mongodb.

In your application.properties, you are using mongodb which is not a valid host.

You need to pass the environment variables for your spring application. For it, you can do something like this in your docker-compose.yml.

version: "3"
services:
  mymongodb:
    image: mongo:latest
    container_name: "mymongodb"
    ports:
      - 27017:27017
  spring-mongo:
    image: spring-mongo:1.0
    container_name: spring-mongo
    ports:
      - 8080:8080
    environment:
      - MONGO_HOST=mymongodb
    links:
      - mymongodb

And in your application.properties,

spring.data.mongodb.host=${MONGO_HOST}

Try depends_on instead of links, it worked for me.

version: "3"
services:
  mymongodb:
    image: mongo:latest
    container_name: "mymongodb"
    network_mode: host
    restart: always
    ports:
     - 27017:27017
  spring-mongo:
    image: spring-mongo:1.0
    container_name: spring-mongo
    network_mode: host
    restart: always
    ports:
     - 8080:8080
    depends_on:
     - mymongodb

With the below docker-compose.yml and application.properties configuration its working for me. docker-compose.yml docker-compose.yml

# Use root/example as user/password credentials
version: '3.1'

services:

  mongo:
    image: mongo:4.4.5
    restart: always
    ports:
      - 27017:27017
    environment:
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example

  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example
      ME_CONFIG_MONGODB_URL: mongodb://root:example@mongo:27017/

application.properties

spring.data.mongodb.authentication-database=admin
spring.data.mongodb.username=root
spring.data.mongodb.password=example
spring.data.mongodb.database=springAppDB
spring.data.mongodb.port=27017
spring.data.mongodb.host=localhost
