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:
- A local computer with a directory where the application that I want to dockerize is located
- A “docker server” running Portainer without shell/ssh access
- A place where I can upload/host the Docker images and where I can pull the images from on the “Docker server”
- 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?
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.
