Certificate Creation Image Build

The dockerfile hosted in this directory is used to build the image required for generating Wazuh Docker single-node and multi-node certificate files

Pre-requisites

1. Verify the Docker Buildx plugin is properly set up
2. For multi-architecture image builds:
   • Ensure QEMU is installed
   • Check permissions to push images to a Docker registry

Useful documentation:

• https://docs.docker.com/build/building/multi-platform/
• https://www.qemu.org/download/

Procedure

Execute the following to run the script used to build the wazuh-certs-generator docker image

cd indexer-certs-creator

./build-image.sh -v <IMAGE_TAG> [-m] [-rg <REGISTRY>]

• Replace <IMAGE_TAG> with the new image desired tag.
• Use the -m flag to build a multi-architecture image (supports both amd64 and arm64)
  • If multiarch build is enabled, the script will attempt to push the image to the specified registry. This image upload will only work if credentials are properly configured.
• Use the -rg <REGISTRY> parameter to specify a custom Docker registry (default is Docker Hub)
