-> Data inside a container is temporary and will be lost once the container stops. Although this may be appropriate for some use cases, ensuring data persistence for databases like MongoDB is crucial.
-> To persist data in a MongoDB container, we use Docker volumes.
-> Docker volumes allow the containers to store data outside of the container filesystem, ensuring data is persistent even after the container is stopped.
-> Create a Docker volume and run the MongoDB container with the volume mounted to ensure data persistence.
docker volume create mongodb
docker run --rm -d --name mongodb -v mongodb:/data/db -p 27017:27017 mongo:latest
-> Log in to the MongoDB container and add sample data.
docker exec -it mongodb mongosh
-> Stop the MongoDB container
docker stop mongodb
-> Run the MongoDB container, login, and check if the data is still present.
