Alpine Linux apk: List out directly installed packages by `apk add`?

  • 772

Is it possible to list packages directly installed by apk add? e.g. apk add docker, apk add lm-sensors file, etc.

Running apk info lists ALL installed packages (including dependencies of installed packages), but I want to narrow this list down to top-level packages that are not dependencies of other packages in order to reproduce these packages on another system.

alpine

  1. A list should be automatically generated and available at /etc/apk/world. See apk-world(5):

    At /etc/apk/world, apk maintains the world, or list of explicitly
    installed packages. This is a plaintext file with one package spec per
    line.

  2. You're using the wrong tool.

    You should use lbu to generate a package list or better yet an overlay file which you can use to bring an Alpine Linux system to a known set of packages.
