🐞 bug report

Affected Rule

Pusher binary wrongly transitioned to target platform. Instead of being run on exec one.

Is this a regression?

introduced by e48c7cc

Description

Trying to push a container from another platform doesn't work if these are not exec compatible.
Example: darwin/arm/v8 vs. linux/amd64

🔬 Minimal Reproduction

Any container_push rule cannot work on a darwin arm machine if building a linux/amd64 container.

bazel run <container_push target> --platforms=@io_bazel_rules_go//go/toolchain:linux_amd64

This results in Exec format error.
