This was my first thought as well. This isn't a replacement for portainer agents on mulitple docker hosts, hopefully that's something that is doable in the future.
I ditched portainer earlier this year to use the command line only, and don't miss it at all. If you're only using docker compose, I really don't see the point of it.
A lot of smaller things, at least for me. The biggest grievance I have with it is the garbage tier UX between hitting "Deploy" on a stack and getting ito to do so. Error messages in the notification bubble get cut off, are unhelpful amd/or disappear too fast. That and the L9g Voewer sucking ass are my main problems with it and why I'll definitely check this out.
Not to mention that there's no way to view those errors messages after the pop disappears (which happens automatically after a few seconds), so God forbid you hit the washroom or check Lemmy while your stack is deploying, no you have to watch that fucker like a hawk.
It is fucking ridiculous that I have to copy and paste error messages just to see what they say.
Portainer has so many tiny broken places that I effectively treat it only as a read-only view. It lists my containers and shows my logs and nothing much else.
It could in theory do quite a bit more, but starting from the fact that it doesn't quite do docker-compose, but its own thing that's somehow similar but different there's just too many tiny issues with it.
Also, it's quite aggressively pushing the paid option without a way to turn that off (or at least turn it down to tolerable levels).
"Read only view" is exactly how we've started treating it. We used to deploy entirely through Portainer, now we work from the command line and just use Portainer as an information layer. And it frankly sucks at that. Doesn't even give you preformance metrics.
UI, just too many annoyances. Fkr example the cut off unhelpfull error messages
compose files, like this project calls it are taken hostage by portainer
git, while you can use a repository there is no comfortable way to test out changes and commit them to git. Would portainer use a sinple file structure for compose files that would not be a problem
Ads, they try to promote there business version via the UI.
I could close my eyes to all of those, but the issue that pisses me off the most is that often enough Portainer just forgets which stacks it has ownership over, forcing you to delete the whole stack, dig up the old compose from its files, and create it again
