Kaleido:TNG failure using python:3.12-alpine and python:3.12-slim-bookworm

[gvwilson]

A user reports, "I tried to run [the test program] in a container using python:3.12-alpine and python:3.12-slim-bookworm images. I installed chromium (apk add —no-cache chromium; apt update && apt install chromium). I get an error regarding "Close() was called before the browser finished opening”".

Test program:

import plotly.express as px
fig = px.scatter(px.data.iris(), x="sepal_length", y="sepal_width", color="species")
fig.write_image("figure.png", engine="kaleido")

Error message:

The above exception was the direct cause of the following exception:

@mschoettle has provided a container for us to try: https://github.com/mschoettle/plotly-image-export-alpine - thank you

Interesting, probably this:

[1023/201538.372535:ERROR:zygote_host_impl_linux.cc(101)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

causing chromium to shutdown immediately.

ill submit something before EOD
