No ADD primitive?

[DC-Shi]

ADD some.tar.gz /data would extract the tarball to destination, but COPY only copy the file, no extraction.

Extracting source code for compile or extract binary files into container would be common usage for docker building from my experience. I hope this primitive can be added into hpccm.

(This might be a docker specific problem.)

Hi @DC-Shi - thanks for your interest in HPCCM.

Docker advises using COPY instead of ADD in nearly all cases.

If you must use ADD, consider the raw primitive (although if you ever intent to generate Singularity definition files from the same recipe, you need to include a Singularity equivalent).

Stage0 += raw(docker='ADD some.tar.gz /data')
