Done (already). As I had read it earlier also.
Even if no body is opening a wordpress website (suppose if even google/other indexing by crawlers has been turned off), even then it uses some ram and cpu? Pls tell.
Of course, if it wasn’t using resources then it couldn’t respond when users visit pages.
The discourse specifications assume nothing else is running on the machine. The minimum is 2gb for a small starter instance. Your site has been around for several years and clearly can’t cope sharing the current server with other applications running in the background.

Running processes use memory. You can shut down apache and mysql and free the ram that they use, but if they are running, they use resources.
This (what to turn off to stop resources being used by the dormant WP sites, and thus saving me to straightway delete /www/domainname folders) is what I was researching for right now, and was shying to ask here.
You again (count lost now) nailed it.
But how can I stop (outer) nginx (I’ve no apache installed) when the same nginx is serving discourse container also. Surely I’d turn off MySql for those websites which are not very much needed currently.
Just add swap.
But if you want things not to use ram, you must stop the processes. You do not need the reverse proxy to rebuild the container. But just add swap.

From a perspective of things working or not working, if you can add swap, you don’t need to configure more RAM. The effect of RAM is to help performance of the site, but for the site to work, what’s important is the total of RAM and swap.
Use the free command to verify that the swap is indeed active and in use - your screenshot shows no swap.
