If you already know Docker CLI, is there a reason to use Portainer? (lemmy.zip)

I often see people mention the Portainer project and how it's useful, but I never hear any reason to use it other than as a more user friendly front end to service management.

So is there any particular feature or reason to use portainer over docker's CLI? Or is it simply a method of convenience?

This isn't only strictly for self hosting, but I figure people here would know better.

Please don't use Portainer.

  • It kidnaps your compose files and stores them all in its own grubby little lair
  • It makes it basically impossible to interact with docker from the command line once it has its claws into your setup
  • It treats console output - like error messages - as an annoyance, showing a brief snippet on the screen for 0.3 seconds before throwing the whole message in the shredder.

If you want a GUI, Dockge is fantastic. It plays nice with your existing setup, it does a much better job of actually helping out when you've screwed up your compose file, it converts run commands to compose files for you, and it gets the fuck out of the way when you decide to ignore it and use the command line anyway, because it respects your choices and understands that it's here to help your workflow, not to direct your workflow.

Edit to add: A great partner for Dockge is Dozzle, which gives you a nice unified view for logs and performance data for your stacks.

I also want to note that both Dockge and Dozzle are primarily designed for homelab environments and home users. If we're talking professional, large scale usage, especially docker swarms and the like, you really need to get comfortable with the CLI. If you absolutely must have a GUI in an environment like that, Portainer is your only option, but it's still not one I can recommend.

You can just connect a (local) Git repo to it and store your compose files over there. There should be even an auto-sync (if you’re into that kind of thing).

Not the point. If you want to interact with the compose files directly through the command line they're all squirelled away in a deep nest of folders, and Portainer throws a hissy fit when you touch them. Dockge has no such issues, it's quite happy for you to switch back and forth between command line and GUI interaction as you see fit.

It's both intensely frustrating whenever it comes up as an issue directly, and speaks to a problem with Portainer's underlying philosophy.

Dockge was built as a tool to help you; it understands that it's role is to be useful, and to get the fuck out of the way when its not being useful.

Portainer was built as a product. It wants to take over your entire environment and make you completely dependent on it. It never wants you to interact with your stacks through any other means and it gets very upset if you do.

I used Portainer for years, both in my homelab and in production environments. Trust me, I've tried to work around its shortcomings, but there's no good solution to a program like Portainer other than not using it.
