Question: apko should be support copy files?

[lpcalisi]

apko have the chance to copy some files? or execute something?

apko is great to gen base images, but is common require that this bases images need some configuration file or script and they are copied in base image in order to abstrac final application images (or images uses for build). Does it make sense? Or we should make this inside of a build system?

the current approach to package them into apk package like this i think https://github.com/wolfi-dev/os/blob/main/container-entrypoint.yaml

thanks @tuananh. I understand that apko should not be able to exec anything in the build that could variate, because this could be against to reproducible and declarative nature.
And.. another example could be, supposing that i'm creating my own nginx base image using apko, and.. i want copy a specific nginx.conf file with some configurations to my final users. Could it be a valid apko case of use?
I suppose it could have this file in the same git repository that apko.yaml file, and this would not change the final result in bits. In case apko don't support this and i will like to use it anyway, should i create a apk with this config file? isn't it too much?

Having support to copy files (which can be anything from binaries, config file, execution code, etc)

If apko whats to be better than Dockerfile ... then I'd suggest have either apko or melange support COPY files/folder funtionality

[kaniini]

Yes, you can copy files into an apk with melange. It’s already supported.

[jpolania]

Just to clarify on this issue. Apko doesn't support copy files and seems to be is the architecture design

If you want to use the copy file function in melange here is a basic example

Imagine you have a file called mycode.sh and you want that file inside your apk image via melange. You need to copy from BUILD_DIR to ${{targets.destdir}}

Example of melange pipeline section

pipeline:
  - runs: |
      BUILD_DIR="/home/build"
      cp "${BUILD_DIR}/mycode.sh" "${{targets.destdir}}/mycode.sh"
      ...
      ...

Hope that helps to everyone who read this post

i have an example (template) here how to package file with melange and then use that package in apko.
