Multi-platform build using docker buildx

[R-HNF]

Purpose

• AWS has introduced cost-effective instances such as m6g, and I would like to switch to it. However, m6g instances, for example, are based on the arm architecture, which causes problems such as not working with container images for the existing amd architecture.
• I would like to create container images for both arm/amd by implementing a multi-platform build using docker buildx.
  • Multi-platform images | Docker Documentation
  • docker/setup-buildx-action: GitHub Action to set up Docker Buildx
