I am using a shell script on Linux in order to execute some Docker commands :
docker exec -t -i test1 passwd
...
docker exec -t -i test2 passwd
And on the second exec command I receive the following error :
docker: "exec" requires a minimum of 2 arguments.
What am I doing wrong, or what am I missing?
Thank you in advance.
I have had the same mistake
docker exec -it gallant_bose
C:Program FilesDocker Toolboxdocker.exe: “exec” requires a minimum of 2 arguments.
See ‘C:Program FilesDocker Toolboxdocker.exe exec –help’.
Usage: docker exec [OPTIONS] CONTAINER COMMAND [ARG…]
Run a command in a running container
The solution, add the command bash in my case:
$ docker exec -it gallant_bose bash
Best wishes!
Update
Also, you can execute docker exec -it gallant_bose /bin/bash for some images

Thank you! After the addition of ‘bash’ everything worked.

Are you sure that test2 exists?
I don’t see any error in your command. If problem persists, can you provide the docker ps and docker images output please?

girod _s the container test2 exists, and the image that I am using (ubuntu based) is present when I run docker images.
