docker buildx fails to show result in image list

The following commands do not show the output ubuntu1 image:

docker buildx build -f 1.dockerfile -t ubuntu1 .
docker image ls | grep ubuntu1
# no output

1.dockerfile:

FROM ubuntu:latest
RUN echo "my ubuntu"

Plus, I cannot use the image in FROM statements in other docker files (both builds are on my local Windows box):

2.dockerfile:

FROM ubuntu1
RUN echo "my ubuntu 2"

docker buildx build -f 2.dockerfile -t ubuntu2 .

#error:

Any idea what's going on? How can I see what buildx prepared and reference one image in another dockerfile?

I had the same problem while working in a pipeline of CI/CD, it was really difficult to understand why it was happening.

But as devatherock mentioned in this comment, you need to only add the --load flag to your build command.

Ok found a partial solution, I need to add --output type=docker as per the docs. This puts the docker in the image list. But I still cannot use it in the second docker.
