| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | A '''Docker container '''is a running instance of a '''Docker image.'''

Each '''container '''runs as an independent entity.

<span style="background-color:#ffffff;">There can be multiple instances of </span><span style="background-color:#ffffff;">'''Docker containers'''</span><span style="background-color:#ffffff;"> for the same </span><span style="background-color:#ffffff;">'''Docker image.'''</span>

'''Containers '''share the OS kernel with each other.

On stopping a container, all the changes made are lost.

| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | We map port 27017 of the container to port 27017 on our system.

This allows us to access the application from our system.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Only narration
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Now we shall implement this process on our system.
|-

Type the command '''sudo space docker space pull space mongo '''in the terminal.

Press Enter.
Enter your password if prompted.

The image will start downloading.

This step may take some time.

Please wait for the download to complete.

'''Run Command'''

| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | In order to run the downloaded image, we will use the Docker '''run '''command. 

This is the syntax for the run command.

The '''run '''command creates a new container for the image specified.

Additional flags can be provided to set parameters.

These parameters can be container name, ports, mode of operation etc.

If no name is specified, a random name is assigned.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Switch to the terminal window.

| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | To run the '''mongo '''image, type the command as shown.

<div style="color:#000000;">'''mongo_commands.txt''' '''code '''file has the commands used in this tutorial.</div>

You may copy and paste these commands in the terminal instead of typing.

Remember to Press the '''Enter''' key after each command in the terminal.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight '''--name mongodb-container'''
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | To set the name of the container, we use the''' hyphen hyphen name''' flag.

Here we set the name of the container to '''mongodb hyphen container.'''
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight

| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | We can set '''environment variables''' for the application using the hyphen e flag.

Here we set the '''root user '''variable.

It is''' MONGO underscore INITDB underscore ROOT underscore USERNAME'''.

The value is '''mongouser'''.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Then we set the '''MONGO underscore INITDB underscore ROOT underscore PASSWORD '''variable.

This variable sets the '''root '''user password.

The '''root '''user password here is '''mongopwd'''.

We will use this password later when we connect to the '''mongodb '''database.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight '''-p 127.0.0.1:27017:27017'''
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Next, we need to bind the host port to the container port using the '''hyphen p flag'''.

Port binding is required to access the container application from our local system.

The host port is specified first, followed by a colon, and then the container port. 

Here, the host port is 27017 and the container port is 27017.

127 dot 0 dot 0 dot 1 refers to the local host.

We map port 27017 of the container to port 27017 on our system.

This means that the '''mongodb '''database will be accessible on port 27017 on our system.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight '''-d'''
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Then we use the '''hyphen d''' flag to run the container in '''detached mode'''.

'''Detached mode''' allows the container to run in the background.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight '''mongo'''

Press Enter
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | 

Finally, we will specify the name of the image to be run.

The name of the image is '''mongo'''.

Press '''Enter''' to execute the command.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight the output of the command.
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | On executing the '''run '''command, we get the id of the container as the output.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Type '''sudo docker ps'''
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | In order to view the running containers, we use the '''ps '''command.

<div style="color:#000000;">Type '''sudo space docker space ps '''</div>

<div style="color:#000000;">Press Enter.</div>

Enter the password if prompted
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight the container id of the container '''mongodb-container'''.
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | You can see the details of the container we created earlier. 

It shows the '''container id, image, command, status, ports and the name'''.

The '''mongodb '''database is now running.

|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Type 
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Now let us connect to this database using '''exec''' command.

Type the command as shown.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight '''mongo-container'''
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Here the '''mongodb hyphen container '''is the Docker container running the mongodb database.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight '''mongosh'''
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | '''Mongosh '''is the command that we are executing.

Mongosh is a shell for interacting with the mongodb database.
|-
| style="background-color:transparent;border-top:0.5pt solid #000000;border-bottom:0.5pt solid #000000;border-left:0.5pt solid #000000;border-right:none;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Highlight 
| style="background-color:transparent;border:0.5pt solid #000000;padding-top:0cm;padding-bottom:0cm;padding-left:0.092cm;padding-right:0.191cm;" | Then we specify the username and password.
