Shell script to harden your ubuntu server for docker deployments

To run the script to harden your ubuntu server use the following steps:

1. SSH into your server as root user.

2. Copy the script to your server. You can either use scp or simply use touch command to create a .sh file in your server and copy the contents of the script.
3. Use chmod +x to change the permissions of the script.
4. Run the script.

That's it. It will automatically make all the required changes to your server.

Note: Please go through the script before running it to understand it or ask ChatGPT to explain it to you :)
