What happened?

Currently, the mlstacks CLI lacks visual feedback in the form of progress bars or spinners when executing commands like mlstacks deploy ... or mlstacks destroy .... This can leave users uncertain about the progress or status of these commands.

Task Description

Integrate Rich progress bars into the mlstacks CLI to provide users with real-time visual feedback when executing commands. The goal is to enhance the user experience by making the interface more interactive and informative without overwhelming the user with excessive visuals.

Expected Outcome

• Smooth and visually appealing progress bars or spinners should be displayed during the execution of mlstacks deploy ... and mlstacks destroy ... commands.
• The progress indicators should accurately represent the status and progression of the ongoing tasks.
• The implementation should not significantly impact the performance of the commands.

Steps to Implement

• Explore the Rich library and identify suitable progress bar or spinner styles for integration.
• Implement the progress bars/spinners in the mlstacks CLI, particularly for the deploy and destroy commands.
• Ensure that the progress indicators are accurately tied to the actual process milestones.
• Test the implementation across different platforms to ensure consistent behavior and appearance.
• (optionally) Update documentation to mention these new UI features for user awareness.

Additional Context

This enhancement aims to improve the overall user experience of the mlstacks CLI, making it more engaging and informative, which is especially helpful in managing expectations during longer-running processes.

I would like to take this up.

Great. Let me know if you have any questions about this, and def take a look at our sister repo where we do similar things with progress bars etc.

[code-master-ajay]

Sure, thanks for letting me contribute.

@code-master-ajay any progress on this or questions about the implementation / approach you want to take?

Hi @strickvl, i looked up rich library and tried to use it with the terraform deploy function, but i am not able to get the terraform output in the code to be able to show the progress.

please let me know if i am doing something wrong, or should i try any other approach.
Sorry for the delayed update.

So I think it might be as simple as emulating how we handle it here: https://github.com/zenml-io/zenml/blob/cdd14528d674e0cafe00173755e556ea00c6343c/src/zenml/cli/integration.py#L274.

I.e. using the context handler around the deployment call. But in any case would be useful to see specifically what you tried as it's hard to give feedback without more information.

i was trying to capture the stdout of tf.apply function, and create a progress bar like this :

Terraform Deployment ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━   0% -:--:--

Which would show the progress percentage and estimated time.

We could read the stdout if we use subprocess but i can't figure out how to do it using the terraform python library.

From the link you have shared i guess we just need to show a static line like
Deploying stack ...
until the terraform runs.

Yeah no need to make it so complicated, I think :) The console.status() method shows a spinner, so I think that's basically what we're looking for.

Sure @strickvl , I will do that . Thanks for the guidance :)
