Adding services to an existing Docker nginx container (lemmy.ca)

Hi, I'm just getting started with Docker, so apologies in advance if this seems silly.

I used to self-host multiple services (RSS reader, invoicing software, personal wiki) directly on a VPS using nginx and mariadb. I messed it up recently and am starting again, but this time I took the docker route.

So I've set up the invoicing software (InvoiceNinja), and everything is working as I want.

Now that I want to add the other services (ttrss and dokuwiki), should I set up new containers? It feels wasteful.

Instead, if I add additional configs to the existing servers that the InvoiceNinja docker-compose generated (nginx and mysql), I'm worried that an update to Invoiceninja would have a chance of messing up the other setups as well.

It shouldn't, from my understanding of how docker containers work, but I'm not 100% sure. What would be the best way to proceed?

Use new containers, that's what they're for.

That would be ideal, per my understanding of the architecture.

So will docker then minimize the system footprint for me? If I run two mysql containers, it won't necessarily take twice the resources of a single mysql container? I'm seeing that the existing mysql process in top is using 15% of my VPS's RAM, I don't want to spin up another one if it's going to scale linearly.

AFAIK it won't and should you still get a bottleneck you can limit the maximum resources a service may use.
