Its the same idea. You are taking the instructions in with-exec and pushing it to the previous type.

In this case, `from alpine` is a function attached to the container type that has many additional functions. You chain them together to do stuff. You can do it through code as if it was any other object, but this shell allows you to do things without code as well.

Perhaps the example is too simple to feel useful, but being able to pipe primitives like files, directories, containers, secrets, and even any custom object makes it possible to rapidly experiment with and compose pipelines.
