docker build gives an error — `ERROR [4/7] COPY dist/codex.tgz codex.tgz``

I would like to run it it docker on my macbook.

I've found the Dockerfile:

bessarabov@m3:~/git/codex$ find .|grep Dockerfile
./codex-cli/Dockerfile
bessarabov@m3:~/git/codex$

But the build id failing:

bessarabov@m3:~/git/codex$ cd codex-cli/
bessarabov@m3:~/git/codex/codex-cli$ docker build --tag codex .

I have also found script codex-cli/scripts/build_container.sh, but running it also produce the error:

I was expecting to be able to build docker just with docker build command, but it looks like the system is expecting to have tgz file build on the host machine.
