I have developed simple Spring Boot Application that performs CRUD operations using MongoDB as database. I have deployed that application in Docker but I get null values while doing GET Request for any items stored in MongoDB. Some of the files required for Docker are provided below:
Dockerfile:
VOLUME /tmp
ADD build/libs/Spring-Boot-MongoDB-0.0.1-SNAPSHOT.jar SpringMongoApp.jar
ENTRYPOINT ["java", "-Dspring.data.mongodb.uri=mongodb://mongo:27018/otp","-jar","/SpringMongoApp.jar"]
docker-compose.yml:
version: "3"
services:
api-database:
image: mongo:3.2.4
container_name: "springboot-mongo-app"
ports:
- "27018:27017"
environment:
MONGO_INITDB_ROOT_DATABASE: otp
networks:
- test-network
api:
image: springboot-api
ports:
- "8080:8080"
depends_on:
- api-database
networks:
- test-network
networks:
test-network:
driver: bridge
application.properties:
spring.data.mongodb.host=api-database
When I checked the MongoDb Docker container using container ID, it is automatically getting connected to test database but not to otp database which I have mentioned in environment section of docker-compose.yml file.
The problem is that your docker container is not persistent, the database will be erased and re-created again each time you run your docker container.
If you add VOLUME
to persist /data/db
, you will get desired result.
I assume your have directory
data/db
in the same place where you have storeddocker-compose.yml
. You may setup custom directory (i.e/tmp/data/db
)
Try this one:
docker-compose.yml:
version: "3"
services:
api-database:
image: mongo:3.2.4
container_name: "springboot-mongo-app"
ports:
- "27018:27017"
volumes:
- "./data/db:/data/db"
environment:
MONGO_INITDB_ROOT_DATABASE: otp
networks:
- test-network
api:
image: springboot-api
ports:
- "8080:8080"
depends_on:
- api-database
networks:
- test-network
networks:
test-network:
driver: bridge
Note: First time, it will be empty database. If you create collections, insert records, etc... it will be saved in ./data/db
