I agree with @Vivek Vaibhav Shandilya's comment.

• In a Docker container, when the main script finishes, the container stops. This can cause the container to restart in a loop.
• To stop this from happening, we need to keep the container running even after the script is complete. I've added this command tail -f /dev/null to your code at the end as shown below.

CMD ["python3.9", "/root/framework/execute_results_testing.py", "&&", "tail", "-f", "/dev/null"]

• Thanks to @kodekloud for clear explanation, I've referred this doc for better understanding about how to keep the docker container running. You can add the command to your Dockerfile or shell script, as shown below.

Start .sh:

echo  "Executing Python script..."
python3.9  /root/framework/execute_results_testing.py  
echo  "Python script finished. Keeping container alive..."
tail  -f  /dev/null

After making the above changes, my container successfully stays alive without restarting.
