Before this change, all platforms that loosely match the provided platform will be fetched even though we only care about 1 of them. As an example when linux/amd64 is requested it will also fetch linux/386 because it is a compatible architecture. This means extra round trips to the registry, potentially even for content that doesn't exist in the remote. This is especially a problem when resolve mode is prefer-local because we'll have the index locally but most likely only one manifest. In this case we'll end up reaching out to the registry to fetch the other manifests unncessarily. With this change instead of fetching all matching platforms it chooses only the best matching platform. Signed-off-by: Brian Goff <cpuguy83@gmail.com>
