File Management

Accessing Files Inside Docker Containers

Enter a Docker container:
- Using Bash (if available):
```
docker exec -it CONTAINER_ID bash
```
- Using Shell (alternative):
```
docker exec -it CONTAINER_ID sh
```
List directory contents:
```
ls -al
```
Read a specific file:
```
cat FILE_NAME
```

Copying Files to a Server

Copy a file to the server:
```
scp ./FILE_NAME root@URL:/tmp
```
Log in to the server and locate the file:
```
ssh root@URL
cd /tmp
ls -al
```

Copying Files to a Docker Container

Copy a file from the server to a container:
```
docker cp ./FILE_NAME CONTAINER_ID:/tmp
```
Enter the container and locate the file:

Using Bash:
```
docker exec -it CONTAINER_ID bash
```
Using Shell:
```
docker exec -it CONTAINER_ID sh
```
Navigate to the /tmp directory:
```
cd /tmp
```

Performing Database Operations

Importing a Database Dump

Upload the dump file to the server:
```
scp ./DUMP_FILE root@URL:/tmp
```
Copy the dump file to the database container:
```
docker cp ./DUMP_FILE CONTAINER_ID:/tmp
```
Restore the database dump inside the container:
```
mongodump /tmp/DUMP_FILE
```

Modifying Database Content

Example: Updating a user's role to "admin":

Log in to the server:
```
ssh root@URL
```
Find the database container:
```
docker ps
```
Enter the container:
```
docker exec -it CONTAINER_ID bash
```
Access the MongoDB CLI:
```
mongosh
```
Select the database:
```
use DB_NAME
```

Update the user's roles:

db.users.findOneAndUpdate(
{ email: "EMAIL" },
{ $push: { roles: "admin" } }
)

Verify the changes:
```
db.users.find({ email: "EMAIL" })
```
