How to write the passed parameters to the container file when starting the container (docker)?

Question

Docker

I create a container and pass parameters

docker run --name my-conteiner -it my-image php -r "hello world"

That's how it works. But if I want to write "hello world" to some file inside the container when starting the container, can I do it directly from docker run?

Answer 1

docker run --name my-conteiner -it my-image command_that_writes_to_file
The same php in your case will write to the container.
An elegant version with a Dockerfile, for example, is described here stackoverflow.com/questions/40238969/how-to-pass-c...
