go_image always builds for linux/amd64 irrespective of host platform

[Chaitanya Munukutla]

🐞 bug report

Affected Rule

The issue is caused by the rule: rules_docker and go_image (possibly other language-specific rules as well)

Is this a regression?

Not sure

Description

When running a go_image target from a darwin/arm64 machine (M1 Pro CPU), the target container image is always built for linux/amd64. Below are key snippets

load("@io_bazel_rules_go//go:def.bzl", "go_binary")
load("@io_bazel_rules_docker//go:image.bzl", "go_image")

go_binary(
    name = "binary",
    srcs = ["main.go"],
    goarch = "arm64",
    goos = "linux",
)

go_image(
    name = "image",
    srcs = ["main.go"],
    goarch = "arm64",
    goos = "linux",
)

🔥 Exception or Error

There is no build error, but when the image is loaded onto the Docker daemon, it shows the following warning

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested
