In these previous posts:
MongoDB – How to install it on macOS
MongoDB – How to install on Windows
we have seen how to install Mongo DB.
In reality, using DOCKER, we can install Mongo DB without install it on our system and in an easier way.
IMPORTANT: For this post, I have used a Windows system but it is the same with Mac or Linux.
We open a terminal instance and, using the command docker images, we can check that we don’t have any images in our system:
Now, with the command docker pull mongo, we will get the Mongo image:
Running the command docker image inspect mongo (where mongo is the image’s name), we can check the properties of the image:
Now, we will run this image in a container that we will call “dockermongo” and where we will define an user Admin, using the command:
docker run -d --name dockermongo -e MONGO_INITDB_ROOT_USERNAME=admindb -e MONGO_INITDB_ROOT_PASSWORD=pass123 mongo
Then, using the command docker exec -it dockermongo bash, we will execute the bash command inside the container, in order to manage our Mongo DB instance:
Finally, running the MongoDB command show dbs, we will see the list of databases :
In this case, we can see that the command didn’t work and the reason is because we have created this container by defining User and Password and so, first of all, we have to login:
Now, if we run the command show dbs again, this will be the result:
