When building linux applications using docker, which system is used as the basic image?

  docker, question

May I ask what kind of system is used as the basic image when you build linux applications using docker? If you use docker, you don’t have to stick to the same basic system and host system of docker … then which is more stable and has better performance? Thank you all

You can build from an empty file system or from lightweight operating systems like busybox and aipine. If you think these system packages are too few, you can build from container optimization versions (Ubuntu and others) of mainstream Linux distributions. The wisest way is to standardize a specific mirror version and use it for all containers as much as possible.
