This is good, but there's a challenge: how does this interact with localization?

eg: make sure to mark the text as left to right in case the parent page isn't
eg: we might want to use a localized date format
other ideas can fit too

Thanks for the feedback! Here's what we can do:

Add dir and lang attributes on the shortcode to handle text direction
Use Hugo's i18n for region name translations
For dates, we can keep the original format for now, but it's possible to parse dates in the script and use Hugo's time formatting

other suggestions are welcome too

LGTM!

@Caesarsage, Thank you. This is a solid implementation that eliminates the need for manual event updates. The filtering logic and error handling are particularly well done.

+# Configuration
+EVENT_URL = "https://events.linuxfoundation.org/about/calendar/?_sf_s=kubecon"
+EVENT_LIMIT = 2
+OUTPUT_PATH = "data/kubecon_events.yaml"


Non-blocking: This could also use CLI flags for URL/limit/output to help with local testing, but the current constant-based approach is also reasonable for a small maintenance script.

dkarczmarski · 2025-12-08T18:48:03Z

This idea seems interesting :)

@Caesarsage

* Use Hugo's i18n for region name translations

region name - does it mean country name and city name ?

for example in:

        <a href="https://events.linuxfoundation.org/kubecon-cloudnativecon-north-america/" class="desktopKCButton"><strong>North America</strong> (Atlanta, Nov 10-13)</a>

there is "North America" + "Atlanta".

lmktfy · 2025-12-08T19:13:23Z

I'd say that the region is "North America". KubeCon North America was most recently held in the city of Atlanta.

lmktfy · 2025-12-08T19:13:34Z

Either before or after we merge this, we could ask the CNCF for a more machine readable version of the page we scrape.

Maybe there is a WordPress plugin that can add RDFa data to the event feed or something? Or they can serve the data we're after as jCalendar?

Caesarsage · 2025-12-08T19:17:56Z

Yes, i agree with this

How do one get this informations from CNCF

lmktfy · 2025-12-08T20:43:08Z

To contact the CNCF, we use https://github.com/cncf/servicedesk

@kubernetes/sig-docs-leads can send a message on your / our behalf @Caesarsage (and it's OK to propose that!)

nate-double-u

Thanks for this @Caesarsage

A concern: this may circumvent the steering committee's ability to approve site-wide changes. Usually any update to the banner needs to be approved. Tho, I suppose if this is run and generates a PR that could be approved that would alleviate the concern.

Also, each banner has a UTM link associated with it generated by the LF Marketing team that wouldn't be captured by scraping the event page.

How would this manage scheduling the banners (and ensure there is no overlap between existing banners, or if there is, how would this decide which has precedence)?

lmktfy · 2025-12-09T19:41:00Z

There are several places we mention KubeCon.

This PR is about mentioning it on https://k8s.io/ (and localized equivalents)

We also have site wide banners, that this PR doesn't plan to touch.

For an Urchin / Google Analytics string, we could put that into a Netlify variable and inject it into production builds. The string isn't secret but putting it into a variable helps avoid tainting the metrics with forks and stale site.

The proposed change here is a utility function that can be used to generate the data used by the shortcode for the event list section on the https://k8.io/ . So yes someone will need to generate the data with the function and raise the PR for the changes.

And as Tim mentioned it doesn't tough the site wide banner .

nate-double-u · 2025-12-12T17:11:11Z

Thanks for clarifying the context, I had it in my head this was a banner tool.

Yes, i agree with this

Hello @Caesarsage and @lmktfy, thank you for proposing this automation approach.

Regarding localization, my understanding is that the current discussion leans toward registering only the region names in i18n, such as North America, Europe, India, and similar, and making those translatable via Hugo i18n. Is that correct?

If so, locations like Amsterdam or Mumbai would not be localized and would always be displayed as their original English names. I just wanted to confirm whether this matches your intention.
(localized pages may end up mixing the local language with English for the location names. this could potentially hurt the user experience on localized sites)

Thanks in advance for the clarification.

I’m not sure if my previous question was understood correctly, but I was trying to refer to exactly the same thing :)

seokho-son · 2026-01-05T15:45:29Z

Yes @dkarczmarski, thanks. I’m aware this point has already been raised by you :),
and I just wanted to check the current understanding and any consensus around it so we can continue the discussion.

seokho-son · 2026-02-02T13:26:20Z

Hi @Caesarsage,
Could you please follow up on the discussion above so that we can proceed?

the change at line 290 seems unnecessary :)

Agreed, we should probably not change localizations in this PR.

nate-double-u

We may be able to build an API to call to get the same data in a cleaner way. Could you add the spec you want as an issue to the Events site here: https://github.com/linuxfoundation/lfevents/issues/new

Otherwise, in the meantime, this looks good to me, thanks @Caesarsage.

nit: why 2? If there are 3 events coming up this would skip one.

I guess if we really want to show 3 upcoming events, change this locally and run the script with that setting.
