Fixed. I closed and reopened this PR to rerun the workflow .

to merge all pubsub demo, some folder will be deleted and it make an error when Quickstart Validation exec cmd cd /home/runner/work/layotto/layotto/demo/pubsub/redis/server/，the script seem to be build on the workflow server，i think it need somebody to update the script or ignore the validation error

Yes you are right :)
The quickstart doc https://mosn.io/layotto/#/en/start/pubsub/start and https://mosn.io/layotto/#/zh/start/pubsub/start used the redis demo:


And Layotto runs these quickstart document in the workflow, see https://mosn.io/layotto/#/zh/development/test-quickstart

So, could u help modify the documentation in this PR?
Just modify the doc to use the new demo code.
If you don't know how to fix it after reading the doc, I can help submit a PR to your branch to fix it :)

[codedededi]

[codedededi]
