You need to pass TARGETPLATFORM as a build arg to docker, otherwise it doesn't know what platform is it compiling for. I suggest taking a look at https://github.com/ruimarinho/docker-bitcoin-core/blob/master/.github/workflows/build.yaml to understand how to build it locally.

[schildbach]

I've been running into the same problem. Why isn't there a default?

[ruimarinho]

@schildbach this image uses the newer and more advanced BuildKit framework from docker, so technically those environment variables are being set by docker buildx and not myself. I don't mind defaulting the internal ARG TARGETPLATFORM to linux/amd64 to make docker build easier to run.
