"Serving" an UI with Rich?

[vladidobro]

Hi,
this is rather a general unix question, not so much specific to Rich.

I have an app that has a global Console, a Live display that shows the current state of the app,
and configured logging that writes to the Console with RichHandler.

When I run that locally or with tmux, I can attach and see the Live display no problem.
When I run the app in production in Kubernetes, it only prints the logs (which is what I want in that situation).

Do you think of any way to "serve" the UI, so I could attach to it on demand?
I am thinking somethings along the lines of writing the Live display to a named pipe tty or something, which I could then read from when I attach?
I do not know of any mechanism that would allow me to do that, do you?

Thank you for any ideas.

For anyone wondering, a way to do it is to just serve the rich console on a unix/tcp socket

# server.py
import socket
from rich.console import Console
from rich.live import Live
from rich.table import Table
from io import TextIOWrapper
import time

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind(('127.0.0.1', 10905))
server.listen(1)
conn, addr = server.accept()
file = conn.makefile(mode='wb', buffering=0)

console = Console(file=TextIOWrapper(file, write_through=True), width=40, force_terminal=True)

# rich.live example
table = Table()
table.add_column("Row ID")
table.add_column("Description")
table.add_column("Level")

with Live(table, console=console, refresh_per_second=4):  # update 4 times a second to feel fluid
    for row in range(12):
        time.sleep(0.4)  # arbitrary delay
        # update the renderable internally
        table.add_row(f"{row}", f"description {row}", "[red]ERROR")

simple client with socat
