Introduction
This article describes how to deploy “Mongo Db” inside Docker Container and interact with “Mongo” Db through bash.
Prerequisites
1.
Docker should be installed on your Machine. 2.
Should have basic knowledge in Docker and its
Commands.
Step
1:
Use the below command to Pull “Mongo” image From “Docker
Hub”
docker pull mongo
You will be getting below output (kind of) after executing
the above command,
Using
default tag: latest
latest:

Status:
Downloaded newer image for mongo:latest
docker.io/library/mongo:latest
Now you could see “mongo”
image by running the below command.
docker images
Step
2:
If you able to view your “Mongo Db” image, then, we can run the “Mongo Db” image inside the Docker
container,
Use the below command to deploy the image inside Docker.
docker run --name
mongoapi -d -p 27017:27017 mongo
To verify, whether “Mongo
Db” image, properly deployed inside the Docker, use the below command.
Docker ps
Above command will give you the below result, if deployment
went well.
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8953411f5ddc mongo
"docker-entrypoint.s…"
About an hour ago Up About an
hour 0.0.0.0:27017->27017/tcp mongoapi
Use the below command to view the “Mongo Db” container
deployment details.
docker inspect
<<container id>>
Step
3:
Below are the different ways to work with Mongo Db
Container.
1.
Using “Bash” 2.
Through Applications (i.e. Using “.Net
Application” and “Mongo Db” Driver. We will see it in another Article)
We will see how to work with “Mongo” Db through Bash,
1.
Using “Bash”
command
docker exec -it mongoapi bash
Execute the above command to enter into container. You will be getting the
below result
root@8953411f5ddc:/#
Enter “mongo” to connect to
Mongo Shell.
mongo (Example: root@8953411f5ddc:/# mongo)
1.
Below command will show the list of DBs present
in the Docker Container
Show
dbs
2.
To Create (or) use Database, execute the below
command. This will create database if it is not exists inside the docker
container.
use
mymongodb
3.
To create a table and insert new values, execute
the below command.
Input:
db.people.save({ firstname: "Tom",
lastname: "This is Last Name” })
Output:
WriteResult({ "nInserted"
: 1 })
4.
To find value inside a table Input: db.people.find({ firstname: "Tom"
})
Output: { "_id" :
ObjectId("5e04db1744f1917378629f71"), "firstname" : "Tom",
"lastname" : " This is Last Name " }
That’s it. In this Article, we have learnt,
1.
To “Pull” Mongo Db Image from Docker Hub. 2.
To deploy “Mongo” Image inside the Docker Container. 3.
To create “Mongo” Db and Tables by inserting
user details.
