Ability to 'disable' an entrypoint in a base image (override to [])

[sfc-gh-ptabor]

I have a base image that has 'entrypoint' set.

I would like to use 'oci_image' to override the entrypoint to [].

but If I try, to do:

  oci_image(
    ...
    entrypoint=[],
    ...
  )

The image stays as is... as the empty entrypoint is ignored:

rules_oci/oci/private/image.bzl

Lines 150 to 151 in 59a0546

	if ctx.attr.entrypoint:
	args.add_joined("--entrypoint", ctx.attr.entrypoint, join_with = ",")

I think that nice solution depends on: bazelbuild/bazel#14434

But I think it could be worked around by declaring:

"entrypoint": attr.string_list(doc = "A list of arguments to use as the `command` to execute when the container starts. These values act as defaults and may be replaced by an entrypoint specified when creating a container.",
  default=["#magic-ignored-entrypoint#"]),

There's a workaround for this, if you provide an empty file to entrypoint, oci_image will set entrypoint to []
