New feature requirements in podman
Support "--secret option with the env attribute" and "RUN --mount=type=cache" in podman
3. Why does the customer need this? (List the business requirements here)
We have some credentials need to be used during the image build while this credentials should NOT be exist in the image. Build ARG cannot solve this requirements because the information still able to view by "docker/podman history <image>". Thus, we have to use -secret instead. The docker features "-secret option with the env attribute" and "RUN --mount=type=cache" were being used in this case.
Now, we would like to migrate from docker to, we would like to request podman to support those 2 features, so that we can migrate to use podman smoothy.
