APP in ElasticBeanstalk

Deploying a Streamlit application on AWS Elastic Beanstalk (EB) can be tricky, especially with configuration files like Procfile not being recognized correctly. Here are some steps and considerations to ensure a successful deployment:

1. Verify Procfile Configuration: Ensure that your Procfile is correctly defined and located in the root directory of your project. For a Streamlit application, the Procfile should typically look something like this:

web: streamlit run app.py --server.port=$PORT

Replace app.py with the name of your main Streamlit application file.

2. Check Directory Structure: Your project directory should have the following structure:

├── .ebextensions/
│   └── (your config files, if any)
├── Procfile
├── requirements.txt
├── app.py
└── (other files)

3. Environment Configuration: Make sure that you have the necessary environment configurations. This can be done using the .ebextensions directory to set environment variables, install packages, or perform other setup tasks.

Create a file like .ebextensions/python.config with the following content:

option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: app:application

container_commands:
  01_migrate:
    command: "streamlit run app.py --server.port=$PORT"

4. Port Configuration: AWS Elastic Beanstalk uses port 5000 by default. Streamlit, by default, runs on port 8501. Make sure to set Streamlit to run on the port that EB expects. You can do this by setting the --server.port parameter to $PORT in the Procfile.

5. Logging and Debugging: Check the logs on Elastic Beanstalk to get more details on what might be going wrong. You can do this via the AWS Management Console or the EB CLI with the command:

eb logs

6. Requirements.txt: Ensure that all the required packages are listed in your requirements.txt file, including streamlit.

7. Re-deploying the Application: After making these changes, try re-deploying your application. If you are using the EB CLI, you can run:

eb deploy

8. Example Configuration: Here is a sample project setup for reference:

Procfile:

web: streamlit run app.py --server.port=$PORT

.ebextensions/python.config:

option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: app:application

container_commands:
  01_migrate:
    command: "streamlit run app.py --server.port=$PORT"

requirements.txt:

streamlit

app.py:

import streamlit as st

st.title("Hello, Elastic Beanstalk!")
st.write("This is a Streamlit app deployed on AWS Elastic Beanstalk.")

By following these steps and ensuring your configuration files are correctly set up, you should be able to deploy your Streamlit application on Elastic Beanstalk successfully. If you encounter specific errors, checking the logs and providing those details can help diagnose further.

I've tried everything you mentioned, I have checked my files and structure over and over again, I have directly accessed the instance to review the logs, and it's always the same, it does not detect my Procfile, therefore, it creates a default one. I don't know where the error is.
