When an image and features is defined, additional build options are not allowed

[Roemer]

Hello all

I found out that defining an image and also features allows to build a new image with the desired features.
Unfortunately, it is not allowed to have image and build at the same time. I need build.options to pass additional parameters (add-host) to the docker command that is used to add the feature to the original image.

The only workaround right now is to create a Dockerfile with just the image as the FROM and then use build with the Dockerfile and not the image at all. Would be nice to be able to pass options when building an image with features as well instead of only when using a Dockerfile.

@Roemer Can we utilize runArgs? Something like 👇

{
  "image": "your-docker-image:latest",
  "runArgs": [
    "--add-host", "customhostname:192.168.1.100"
  ]
}
