Cloud Runner on production instance

[Rob E]

I have a two part question that I need help on.

If I utilize Cloud Runner and it is installed on my preprod instance, then I clone over said instance will I need to reinstall Cloud Runner?

If so, do I then have to install cloud runner on my prod instance in order for the installed app to go along in the clone?

Which to me is counter intuitive due to ATFs in general because, best practices say to never run ATF on your prod instance.

Hi there,

Yes you would install the plugin on production, though you would keep the system properties disabled (false).

Or let me put it this way, ATF itself is also already on production. And best practice is to promote all your suites and tests also to production. Though again, leaving the system properties disabled. And then or manually enable the system properties on subproduction or using Clone Preserver so no manual step involved.

How about the automatic mTLS activation then? Will that happen also in production even if the ATF Test Generator and Cloud Runner won't be taken into use there but just installed in order to avoid cloning issues?

From https://www.servicenow.com/docs/bundle/xanadu-servicenow-platform/page/administer/atf-test-generator...:

"Notice that mLTS is activated automatically and causes a rolling restart of the application nodes."

See KB1639216 for more information: https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB1639216

As there are potential risks with enabling mTLS, it would be better to avoid that in the production instance.
