Recommended production docker setup

[jcpprojects]

What is the recommended docker setup for production if you want to have several Docker instances?

From here:

and here:
#924

Seems we need to persist /var/www/html

But then do we need a shared volume with all the code to be able to run more than one machine? Isn't this going to impact performance as some other posts suggest due to slower file access?

Some other social media posts suggest to only persist wp-content/uploads directory, and core installation and plugins would come from Docker. I think should work, but then I am not sure about other local files which might be lost during updates which could be used by plugins, or .htaccess mentioned on the first link.

On the link below this solution is also suggested and used with mixed opinions (external db, persist wp-content/updates and replace the rest on every update), but I cannot see an official documentation supporting this.
