Proper way to create images with installed software

[humphd]

What's the right way to build an image with a bunch of things pre-installed? For example, let's say I want an alpine base, but using apk to add required software? Do I manually do this then re-use the resulting machine? Can I do it programmatically?

In a Dockerfile I'd use RUN and do it as part of the build. What's the equivalent here?

You can use and create a smolfile or create a packaged . smolmachine. .
