From 5f4f0509c44f556b9aba834900ea25d1688495ae Mon Sep 17 00:00:00 2001 From: Nalin Dahyabhai Date: Tue, 2 May 2023 18:04:28 -0400 Subject: [PATCH] copy: add --multi-arch=sparse:... Add a "sparse:..." value for the copy --multi-arch option, where the "..." is a comma-separated list of instance digests, platform specifications, or the literal word "system" to signify the local platform.

Typically, this will be +// images and runtimes that should make these declaring which platform they +// support specifically. This looks roughly as follows: +// +// type Platform struct { +// Architecture string +// OS string +// Variant string +// } +// +// Most images and runtimes should at least set Architecture and OS, according +// to their GOARCH and GOOS values, respectively (follow the OCI image +// specification when in doubt). ARM should set variant under certain +// discussions, which are outlined below. +// +// # Platform Specifiers +// +// While the OCI platform specifications provide a tool for components to +// specify structured information, user input typically doesn't need the full +// context and much can be inferred. To solve this problem, we introduced +// "specifiers". A specifier has the format +// `||/[/]`. The user can provide either the +// operating system or the architecture or both. +// +// An example of a common specifier is `linux/amd64`. If the host has a default +// of runtime that matches this, the user can simply provide the component that +// matters. For example, if a image provides amd64 and arm64 support, the +// operating system, `linux` can be inferred, so they only have to provide +// `arm64` or `amd64`. Similar behavior is implemented for operating systems, +// where the architecture may be known but a runtime may support images from +// different operating systems. +// +// # Normalization +// +// Because not all users are familiar with the way the Go runtime represents +// platforms, several normalizations have been provided to make this package +// easier to user. +// +// The following are performed for architectures: +// +// Value Normalized +// aarch64 arm64 +// armhf arm +// armel arm/v6 +// i386 386 +// x86_64 amd64 +// x86-64 amd64 +// +// We also normalize the operating system `macos` to `darwin`. +// +// # ARM Support +// +// To qualify ARM architecture, the Variant field is used to qualify the arm +// version.
