registry:2

problem with kamal2 : if I configure kamal to push to repository 120.0.0.1:5000 the buildx kamal container have no access to this (no network mapping) so only way to be able to push to local would be to expose the port 5000 and push to outside world 😒 so I abondon kamal local registry setup. maybe kamal 3 will solve this
