Overview
A build infrastructure setup process that creates a Docker Buildx builder instance for multi-architecture image builds.
Description
Buildx Builder Setup creates a dedicated Docker Buildx builder instance that supports multi-platform builds. The builder uses QEMU emulation to build images for architectures other than the host. This is required for creating images that support both amd64 and arm64 platforms.
Usage
Use this principle before building multi-architecture Docker images. The builder must be created once per build session and removed after builds are complete.
Theoretical Basis
- Builder Creation: Create a named Buildx builder instance using docker buildx create.
- Builder Activation: Set the builder as the active builder using --use flag.
- Platform Support: The builder leverages QEMU for cross-platform compilation.
