From fbe2bd87b0581bdd1651689b9b8a01d0d5116517 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Mon, 22 Aug 2022 14:53:57 +0200 Subject: [CI:DOCS] elaborate on image lookups of foreign platforms After pulling/creating an image of a foreign platform, Podman will happily use it when looking it up in the local storage and will not pull down the image matching the host platform. As discussed in #12682, the reasoning for it is Docker compatibility and the fact that user already rely on the behavior. While Podman is now emitting a warning when an image is in use not matching the local platform, the documentation was lacking that information.
