Preferred IDE: Pycharm

Test the Streamlit app locally:

1. Install required dependencies:

   pip install -r requirements.txt

2. Run the Streamlit app locally:

   streamlit run app.py

Building the Docker image

(Note: Run as administrator on Windows and remove "sudo" in commands)

3. Important - Make sure you have installed Docker on your PC:

   • Linux: Docker
   • Windows/Mac: Docker Desktop

4. Start Docker:

   • Linux (Home Directory):

     sudo systemctl start docker

   • Windows: Start Docker engine from Docker Desktop.

5. Build Docker image from the project directory:

   sudo docker build -t Image_name:tag .

(Note: Rerun the Docker build command if you want to make any changes to the code files and redeploy.)

Running the container & removing it

6. Switch to Home Directory:

   cd ~

   List the built Docker images:

   $ sudo docker images

7. Start a container:

   sudo docker run -p 80:80 Image_ID

8. This will display the URL to access the Streamlit app (http://0.0.0.0:80). Note that this URL may not work on Windows. For Windows, go to http://localhost/.

9. In a different terminal window, you can check the running containers with:

   sudo docker ps

10. Stop the container:

    • Use ctrl + c or stop it from Docker Desktop.

11. Check all containers:

    sudo docker ps -a

12. Delete the container if you are not going to run this again:

    sudo docker container prune

Pushing the Docker image to Docker Hub

13. Sign up on Docker Hub.

14. Create a repository on Docker Hub.

15. Log in to Docker Hub from the terminal. You can log in with your password or access token.

    sudo docker login

16. Tag your local Docker image to the Docker Hub repository:

    sudo docker tag Image_ID username/repo-name:tag

17. Push the local Docker image to the Docker Hub repository:

    sudo docker push username/repo-name:tag

(If you want to delete the image, you can delete the repository in Docker Hub and force delete it locally.)

18. Command to force delete an image (but don't do this yet):

    sudo docker rmi -f IMAGE_ID
