Can't find the image

Hallo,
I am a bit puzzled — after compiling a react-app it is not shown under ”docker image”
See the screenshot

I am looking forward hearing from you

The compilation shown on the screenshot seems to be Node.js
Nothing to do with docker.

What instruction did you follow to create a docker image?
Also there is a more modern way to create docker images using Build Kit. (Replace docker build with docker buildx build)
Should you use that method it does not add the image automatically in your available images and it not pushed to a registry neither.

In such scenario a warning message tells you your compiled docker image is kept in the cache so that you can rerun the command with either --load or --push switches.
