[Tracking] Examples Repository Maintenance: Status of All Demos on KubeEdge v1.22+

[FengGaoCSC]

After testing most examples against KubeEdge v1.22 (latest stable as of April 2026), many demos are outdated or broken.

This issue serves as a central tracking board so community members can easily see the current status of each example, know which ones are already being worked on, and pick up examples that still need help.

Goal:

• Improve user experience (examples should work out-of-the-box)
• Reduce maintenance burden
• Encourage community contributions through clear visibility

How to Contribute

• Comment below with the example name you want to work on (e.g. "I'll take web-demo" or "Working on ke-twitter-demo").
• Once you start, update the "Handled By / PR" column in this table (you can edit the issue description or ask a maintainer to update it).
• Reference this issue in your Pull Request.
• If an example already shows a PR link or "In progress", please coordinate with the person working on it to avoid duplicate effort.

Advice

I suggest removing the old and outdated examples from the KubeEdge examples repository, as they are useless and incompatible with the modern architecture of KubeEdge. Keeping them will cause confusion for developers, for example in Issue #5758 (kubeedge/kubeedge#5758), where other users have also been confused by these examples.
