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?
Aren’t containers the product of compose files? i.e. the compose files spin up containers. I understand the architecture, I’m just not sure about how docker streamlines separate containers running the same process (eg, mysql).
I’m getting some answers saying that it deduplicates, and others saying that it doesn’t. It looks more likely that it’s the former though.
