Looks like a build-arg is missing somewhere?

17:48:38 Step 1/49 : ARG GO_IMAGE
17:48:38 Step 2/49 : FROM ${GO_IMAGE} as builder

@thaJeztah it's because arm64 (armv8) isn't available for golang:1.11.5, ping @tianon

❯ docker manifest inspect golang:1.11.5 | jq '.manifests | .[] | select(.platform.architecture=="arm")'
