Yep, hoping to get to this over the next few weeks |

A friendly reminder that this issue had no activity for 30 days. |

This is so badly needed with Java projects that involve multiple |

any more update? |
|
bump this is a good idea |
|
any news? :) |
|
Could you give me a sample Containerfile that would use this? |
|
@rhatdan Of course. This sort of thing is useful in a workspace of any language where nested manifest files are involved. Here is an example in Rust (they are working on toolchain support for building only dependencies without project source, but that's not our concern). Alternatively, here is an example with Maven (which has existing toolchain support). To optimise layer caching, you would want something like this: COPY --parents **/pom.xml ./
RUN mvn dependency:go-offlineWithout |

https://github.com/larixer/docker-js-monorepo has some pretty good examples as well. |

Description
Docker added a
--parentsoption to the DockerfileCOPYcommand last year:moby/moby#35639
moby/buildkit#3001
https://docs.docker.com/reference/dockerfile/#copy---parents
buildah doesn't know how to handle
COPY --parentsso errors out on Dockerfiles which use it.I'm seeing increasing use of
--parentsin Dockerfiles I have to deal with, which is making it hard to use podman/buildah instead of Docker.--parentsis also a genuinely useful option on its own, so would be nice to have not just for compatibility.It's quite useful to be able to do things like
and maintain the directory structure in the destination without having to list out every single file.
