Description
Description
Build image docker will ignore ENTRYPOINT in docker 23.x
And this bug causes the compiled image to run getting error 'Error response from daemon: No command specified' in the k8s cluster.
btw, i install docker follow docker docs.
Reproduce
Dockerfile
FROM nginx
ENTRYPOINT ["echo", "hello world"]
build image
$ docker build . -t ngx -f Dockerfile && docker inspect ngx |grep -i entrypoint
"Entrypoint": null,
"Entrypoint": null,
Expected behavior
$ docker inspect ngx |grep -i entrypoint
Entrypoint: ["echo", "hello world"]

Research direction
Reproduce the report with the provided Dockerfile, docker build command, and docker inspect output using the documented 23.0.1 client and 19.03.5 daemon versions. Compare the result with matching client and daemon versions to isolate the compatibility boundary. Done means ENTRYPOINT is preserved in the built image and the regression is covered by an appropriate test.
