Why you need telnet to other container? if you want to copy files from one container to another container then you can use

docker cp <containerid>:<path/to/copy> <conatinerid>:<path/to/copy>

Docker container is like lightweight os that has minimum but necessary requirements and telnet is definitely not one of them but still if you want telnet in container and you are using ubuntu image you can install telnet in container with

apt-get update && apt-get install telnet

And if you are using another image you can include telnet in a docker file and from that image you can use telnet into container.

Sorry for writing this in answer. Not having reputation for comment but i hope you can understand.

To understand your question correctly, do you meant to say telnet is not found inside the running container? If not then you can install if while building the image itself.
