While trying to build a custom add-on from a SSH login, I am getting the following message…

DEPRECATED: The legacy builder is deprecated and will be removed in a future release.
Install the buildx component to build images with BuildKit:

  • copy files to /addons
  • ssh to HA OS
  • docker build …

The Dockerfile has new features which need buildx

The software is here… (including the Dockerfile)
