Report #101457

[bug\_fix] ERROR: Multiple platforms feature is currently not supported for docker driver. Please upgrade to a different driver \(e.g., "docker-container"\)

Create a custom builder with the docker-container driver: docker buildx create --name multi --driver docker-container --bootstrap --use, then build with docker buildx build --platform linux/amd64,linux/arm64 .... The default docker driver is embedded in the daemon and only builds for the host platform; the docker-container driver runs a BuildKit container that can produce multi-platform manifest lists, optionally using QEMU for non-native architectures.

Journey Context:
You want one image tag for both x86 and ARM in CI. You run docker buildx build --platform linux/amd64,linux/arm64 -t myapp . and immediately get the 'Multiple platforms feature is currently not supported for docker driver' error. You assumed buildx already used a container builder, but the default builder is still the docker driver. After creating a docker-container builder and bootstrapping it, the same command emits a manifest list. On Linux you may also need QEMU binfmt registered for architectures that need emulation.
