How do YOU create your Docker images? (lemmy.ml)

Currently I’m planning to dockerize some web applications but I didn’t find a reasonably easy way do create the images to be hosted in my repository so I can pull them on my server.

What I currently have is:

  1. A local computer with a directory where the application that I want to dockerize is located
  2. A “docker server” running Portainer without shell/ssh access
  3. A place where I can upload/host the Docker images and where I can pull the images from on the “Docker server”
  4. Basic knowledge on how to write the needed Dockerfile

What I now need is a sane way to build the images WITHOUT setting up a fully featured Docker environment on the local computer.

Ideally something where I can build the images and upload them but without that something “littering Docker-related files all over my system”.

Something like a VM that resets on every start maybe? So … build the image, upload to repository, close the terminal window, and forget that anything ever happened.

What is YOUR solution to create and upload Docker images in a clean and sane way?

Genuinely curious, what would the advantages be?

Also, what if the Linux distro does not have systemd?

[–] Cyberflunk@lemmy.world 1 points 1 year ago

I was just making a meme dude. Personally, I like systemd, it's more complicated to learn, I ended up reading books to really learn it properly. There's 100% nothing wrong with cron.

One of the reasons I like timers is journalctl integration. I can see everything in one place. Small thing.

[–] moonpiedumplings@programming.dev 1 points 1 year ago

The chances I am going to manage a linux distro without systemd are low, but some systems (arch for example) don't have cron out of the box.

Not that big of a deal since it's easy to translate them all, but that's one of the reasons why I default to systemd/timer units.
