In this article, we are going to understand MongoDB along with its Docker Composer and its Visual Studio Code extension playground. MongoDB: MongoDB is a source-available cross-platform document-oriented database. It is also called a NoSQL database or Non-Relational database. In MongoDB 'Collection' is equivalent to the Table in SQL database. In MongoDB data is stored as 'Document' that is equivalent to a table record in an SQL database. The 'Document' contains JSON data which will be stored in BSON(Binary JSON) format. MongoDB Docker Composer: Let's implement docker-compose to create a MongoDB docker container. (Step 1): Download and install the 'Docker Desktop' application. The application should be in running mode. (Step 2): Add a new folder for our MongoDB docker composer. Then add the file like 'docker-compose.yml'. docker-compose.yml: version: '3.8' services: mongodb: image: mongo:5.0 volumes: - ./mongo/dat

PostgreSQL is a free open-source relational database management system. In this article, we will learn basic steps to run the PostgreSQL Docker image. Install And Setup Docker: Step1: Download docker into our local system "https://docs.docker.com/desktop/" . Docker was available for all desktop operating systems. Step2: After downloading the docker installer, then install it. Now to run any docker containers(eg: Redis, MongoDB, PostgreSQL, etc) this docker instance we just installed should be active(should be running). Postgres Docker Image: We have to download or pull the Postgres docker image into our local system by running the below command. docker pull postgres Run Postgres Docker Container: After downloading the Postgres image, need to start the container by running the below command. docker run --name mypostgres -e POSTGRES_PASSWORD=secret -p 5432:5432 -d postgres --name flag to specify the name of our container. -e flag to specify an environmental variabl
