Overview
A container image build process that produces images supporting multiple CPU architectures from a single build command.
Description
Multi Architecture Image Build uses Docker Buildx to create container images for both linux/amd64 and linux/arm64 platforms simultaneously. This ensures Kafka Docker images work on both x86 servers and ARM-based systems (like AWS Graviton). The build uses docker buildx build with the --platform flag to specify target architectures.
Usage
Use this principle when releasing official Kafka Docker images. Multi-arch images ensure broad platform compatibility without requiring separate image tags per architecture.
Theoretical Basis
- Multi-Platform Build: Use --platform linux/amd64,linux/arm64 to build for both architectures.
- Build Args: Pass kafka_url and build_date as build arguments to the Dockerfile.
- Combined Push: With --push, the build and push happen atomically, creating a multi-arch manifest.
