Let’s go through it.
proxy: image: nginx:1-alpineI already have one running, why do I now need another one installed als another container exclusively for Lemmy?pictrs: image: asonix/pictrs:0.4.0-beta.19I have no other use for this except for Lemmy, why do I need another container just for this application I never heard of?postgres: image: postgres:15-alpineI have absolutely no use for Postgres. Why do I need to install a database server as container just for being used by Lemmy, and Lemmy only?And then, yes, of course,
lemmyandlemmy-uiSo 5 different containers (and 4 volumes, and 2 networks) all set up only for Lemmy, cluttering my setup – not counted in all the volumes, containers, and networks set up by the 3 additional containers.
And since I’m pinned to specific versions I need to manually check new/changed dependencies when updating Lemmy instead of just rebuilding the container.
I still see no point in that.
It is common to run more than one application in a given server. Nginx, for example, is widely used as a reverse proxy and web server for operating multiple containerized applications on the same server. Postgres is a commonly used database that can potentially be used on hundreds of applications simultaneously. Duplicating them on all containers would just create a mountain of problems and waste resources for no real benefit.
If all you’re running is lemmy then why are you so upset about containers “cluttering” up things? What is there to clutter up, your
docker psoutput ? If you want, just pretend the host is itself a container running lemmy (which it might just be, depending on your host!). Alternately, make your own nested container that just does adocker-compose upand pointlessly duplicate all the services you want. Complaining that the container managers don’t do this for you, to the detriment of others who don’t share your specific niche, is just blatantly entitled and absurd.I use it as reverse proxy already. Why do I need to install a reverse proxy for Lemmy?
That’s the thing: i don’t.
But maybe I should get a real or virtual machine used exclusively for Lemmy and adding its Docker environment to my current Portainer installation.
You don't. Configure the one you already have and just remove that entry from your docker-compose. This is exactly why they're handled as separate containers.
And by “configuring” you mean nothing more than simply setting up the connection from example.com:443 to the machine and exposed port? That would at least solve 1 out of 5 issues I have … :)
