Local source for docker_image_load

[nabeelsherazi]

SUMMARY

Hello! It would be useful to have to have the option to set local_src: true in docker_image_load and save some steps in Docker image loads.

ISSUE TYPE

• Feature Idea

COMPONENT NAME

community.docker.docker_image_load, local_src: true

ADDITIONAL INFORMATION

Currently, to load a Docker image from a tar or tar.gz, one must first copy it to the remote, then run Docker load. This could be done in one step by piping the image tarball into docker load directly, e.g. from the shell we typically do ssh user@host "docker load" < image:tag.tar.gz to save the separate copy and load steps. If docker_image_load supported a local_src option, something similar could be implemented.

- name: Load all image(s) from the given tar file
  community.docker.docker_image_load:
    path: /path/on/controller/to/image.tar
    local_src: true
  register: result

That's not how Ansible modules work. Modules cannot access files on the controller (except if you force execution on the controller, for example with delegate_to: localhost). This could be done with an action plugin, but that basically also has to copy the file over to the target, run the module there, and then delete the copied over file. I think this is out of scope for this collection though.
