Solution to the issue 'No output using this example #1'

[Kolman-Freecss]

Hi mate!

I checked the issue 'No output using this example #1' because I had that also, so I fixed it with the next changes and now it works correctly:

The main point and the fix is the creation of the virtual environment inside the docker and the specification of the environment variable PATH. The other modifications is only extra features, check it if you want! :)

Changes:

• Update to Python 3.10
• Execute crontab using only the keyword 'crontab'
• Creation and execution of a virtual environment inside docker
• Tail the logs to check the logs directly on the console

Hello,
Thanks for the PR, but I have two points that I would like to highlight

• the virtual environment is discouraged in the docker container, the main purpose of the virtual environment is isolation while the docker-container has already come with isolation
• We should not write logs to file and tail, it will kill the primary purpose of the container "one process per container" and it will also need extra effort to truncate the log file incase of extensive logging.

So writing logs to stdout/stderror is best choice.

Let me bump the version, and will add the comment

Your first point about the isolated system it's a good point to debate, but you could isolate both environments (System - Python)

Check these links:

• https://vsupalov.com/virtualenv-in-docker/#:~:text=In%20Conclusion,over%20your%20Python%20environment%20%26%20dependencies.

About the second point I agree with you, they are best practices, but this is a quick solution (and not a bad solution in my personal opinion).

However, if I not specify the virtual environment and the PATH my application doesn't works.
