Part 1: Working with Supplier Images

Grant executable permission to download_drive_file.sh
```
sudo chmod +x ~/download_drive_file.sh
```

Command to download supplier data

./download_drive_file.sh 1LePo57dJcgzoK4uiI_48S01Etck7w_5f supplier-data.tar.gz

Extract the downloaded data
```
tar xf ~/supplier-data.tar.gz
```
Create a new Python script named changeImage.py to convert raw image data to jpeg
Grant executable permission to changeImage.py
```
sudo chmod +x ~/changeImage.py
```
Confirm whether the properties of new image has been properly converted
```
file ~/supplier-data/images/003.jpeg
```

Grant executable permission to example_upload.py
```
sudo chmod +x ~/example_upload.py
```
The command below will upload the sample image to web server
```
./example_upload.py
```
Create a Python script named supplier_image_upload.py to upload converted images to web server
Grant executable permission to supplier_image_upload.py
```
sudo chmod +x ~/supplier_image_upload.py
```

At this point, the Django server has been running. The Django REST framework can be accessed on URL below.
```
{PUBLIC_IP}/fruits
```

Try POST method with the following json data

{
  "name": "Test Fruit",
  "weight": 100,
  "description": "This is the description of my test fruit",
  "image_name": "icon.sheet.png"
}

Create a Python script named run.py to read item description from directory and upload all description to web server
Grant executable permission to run.py
```
sudo chmod +x ~/run.py
```
Run the script
```
./run.py
```
Validate the process and ensure all images are shown on the web
```
http://{public_ip}/
```

There are 3 scripts that have to be created, reports.py, emails.py, and report_email.py
The reports.py will create a pdf report based on name and weight of items supplied by suppliers.
The emails.py will create a message object and send message to receiver. The content of the email includes the pdf file generated by reports.py
Finally report_email.py is the main script that will call both reports.py and emails.py to perform these tasks.
Grant executable permissions to report_email.py
```
sudo chmod +x ~/report_email.py
```
Run the script
```
./report_email.py
```
Confirm that the email is actually sent to the receiver by logging in to webmail
```
{public_ip}/webmail
```

The final part is about creating an automatic alerting system in case abnormal behavior in the system is detected
Create a Python script named health_check.py to monitor CPU usage, disk space, available memory, and localhost connection
The check should be performed every 1 minute. If abnormal behavior occurs, the script will send an email to receiver.
While the script is running, install stress toll to test the script
```
sudo apt install stress
```
Run the stress tool and check whether alert message is received on receiver side.
```
stress --cpu 8
```
