🧭 Type of Feature

Enhancement to existing functionality: Enhance the current container build tools to include changes needed to support container build on s390x architecture.

🧭 Epic

Title: Enhance container build scripts to support s390x
Goal: Consistent container build process regardless of platform architecture
Why now: Depend build capability needed for s390x as part of ability to provide multi-arch container images.

🙋♂️ User Story 1

As a: Developer
I want: The MCP gateway Docker image to support s390x architecture
So that: I can run deploy and run MCP gateway on s390x without having to build the container locally.

✅ Acceptance Criteria

Scenario: Update existing container build scripts as needed to support s390x
  Given a developer is running on s390x or using emulation 
  When Allow "make build-container" to build for s390x architecture as a user can do on any other architecture
  Then Successfully build a container image for s390x without customer modifications

🙋♂️ User Story 2

As a: Developer
I want: to ensure that the introduction of s390x is supported by buildha/podman and docker build
So that: existing build/runtime tools remain consistent across architectures

✅ Acceptance Criteria

Scenario: Validate that build and runtime of a container is consistent between docker and podman.
  Given that docker and podman are already integrated into the build scripts for other platforms. 
  When a developer wishes to build a container for s390x. 
  Then Successfully build a container image for s390x without errors

🔗 MCP Standards Check

• Change adheres to current MCP specifications
• No breaking changes to existing MCP-compliant integrations

🔄 Alternatives Considered

make compiler flag to include specific changes needed in container builds for s390x
Changes only to Makefile where not sufficient because of the way multi-arch container builds are built.

📓 Additional Context

Adding s390x support includes a minimal set of changes to the build scripts in a way that does not alter existing architectures.
