How to create snapshot ISO-image from Ubuntu server?

mt flag

I intend to run computationally intensive calculations on expensive cloud servers. Setting up the environment (starting Ubuntu server via cloud API, downloading and installing Python/models, downloading input file) takes 10-15 minutes, which causes unnecessary costs at 0.025 cents per minute. I could save a few minutes with a Docker image.

However, I would gladly choose the path via my own server image. Unfortunately, I fail when trying to export a fully configured Ubuntu instance as an ISO image: Instructions on the Internet are limited to individual folders or require software with a GUI, which I would like to avoid in order to be able to automate this process later with a script.

Can anyone help me? Desirable would be a CLI command like makeiso / ~/custom-ubuntu.iso, the output file of which I can define as an image at cloud server providers.

Docker images are not made using iso files. Neither does an iso help you creating cloud instances. You should read the Docker documentation on how to build images.

iso and docker images are different and meant for different use cases. If you want to create ISO use any cloud platform and create ISO image directly via UI/CLI and you can download as well locally, some other way also available on internet to create iso directly from local machines, remember steps may differ based on os type.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
