Understanding Docker Container Run Errors

I'm building an image of the Dockerfile and starting the container.
Run'docker COMMAND --help' for more information on a command.
appears.

I don't think the syntax is wrong, but is there anything strange about it?
Please let me know.

The following is also a description of the commands (processing):

Dockerfike

FROM python
WORKDIR/tmp/mydir
COPY./ex01/tmp/mydir/
CMD ["/bin/bash" ]

Docker image

PSC:\PC-Work\dockereenv\ex01>docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
img_ex01_py_01 latest 5056c1313323 13 minutes ago 932MB

Docker container run results


# Create and launch a container called testpy from the image img_ex01_py_01

 docker counter run-it --name testpy img_ex01_py_01

You must write container instead of container.

By the way, what version of Docker is being used?
The error message could not be reproduced on hand 20.10.20.
Due to the previous question, I was wondering if the docker that I didn't expect was running.

docker: 'countainer' is not a docker command.
See'docker --help'

container subcommand is incorrect

PS>docker container run
