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?

Do you mean that you want to build the docker image on one computer, export it to a different computer where it's going to run, and there shouldn't be any traces of the build process on the first computer? Perhaps it's possible with the --output option.. Otherwise you could write a small script which combines the commands for docker build, export to file, delete local image, and clean up the system.

I want to export the image to my repository/registry and then use it somewhere else. I also don't want to set up a complete docker environment with all the "magic" things. Just build an image and upload it.
