Running the application

Let's start MongoDB using the Docker run command:

docker run -d --name mongo -p 27017:27017 mongo

Something that may be useful for us is the Mongo database client. Using this, it is possible to create a new database and add some users with credentials. If you have Docker installed on Windows, the default virtual machine address is 192.168.99.100. The Mongo container has port 27017 exposed as a result of setting the -p parameter inside the run command. Well, in fact, we do not have to create the database because, when we provide the name while defining the client connection, it will automatically be created if it doesn't exist: 

Next, we should create a user for the application with sufficient authority:

Finally, we should set the Mongo database connection settings and credentials in the application.yml configuration...
