Spike - Docker ARM 4.x - Analyze the changes to be migrated to adapt the multi-architecture build

[c-bordon]

Description

We need to analyze the changes made in this issue (https://github.com/wazuh/wazuh-automation/issues/2696) and adapt them for 4.14.x. We must keep in mind that we should only migrate the changes related to the multi-architecture build.

Functional requirements

• Multi-platform Docker images

  • Each current Intel-only image must be migrated to a multi-architecture image (AMD64 + ARM64) using Docker buildx manifests.
  • No separate -arm tags will be published.

Implementation restriction

Multi-platform images must behave identically to the current Intel-only images (same base image, entrypoints, environment variables, config behavior).
