Use Docker to Distribute CLI Application

I'm somewhat new to Docker. I would like to be able to use Docker to distribute a CLI program, but run the program normally once it has been installed. To be specific, after running docker build on the system, I need to be able to simply run my-program in the terminal, not docker run my-program. How can I do this?

I tried something with a Makefile which runs docker build -t my-program . and then writes a shell script to ~/.local/bin/ called my-program that runs docker run my-program, but this adds another container every time I run the script.

EDIT: I realize is the expected behavior of docker run, but it does not work for my use-case.

Any help is greatly appreciated!

If you want to keep your script, add the remove flag --rm to the docker run command. The remove flag removes the container automatically after the entry-point process has exit.

Additionally, I would personally prefer an alias for this. Simply add something like this example alias my-program="docker run --rm my-program" to your ~/.bashrc or ~/.zshrc file. This even has the advantage that all other parameters after the alias (my-program param1 param2) are automatically forwarded to the entry-point of your image without any additional effort.
