Keyboard input not working after attaching to a running container

[boffti (Aneesh Melkot)]

Host machine -
Lenovo Flex 5 - AMD Ryzen 7
Windows 11 Home 64 bit
Docker Desktop 4.12.0 (85629)

I can start/run containers from Docker Desktop and connect to them with the integrated CLI from there. I can execute what commands I want on that.

The issue starts when I Start/Run containers through my terminal.
I attach to them using “docker attach ”
However, in the attached shell, I am not able to type anything, the keyboard input is simply not working.

The issue also exists when I run the container using the -i flag. I can see the container shell but cannot type anything. Ctrl + c exits the shell.

I have tested this on CMD, Git Bash, and Cmder’s various shells on my machine.
Reinstalled Docker Desktop also and still the issue persists.

Let me quote the manual here:

@https://docs.docker.com/engine/reference/commandline/attach/

Use docker attach to attach your terminal’s standard input, output, and error (or any combination of the three) to a running container using the container’s ID or name. This allows you to view its ongoing output or to control it interactively, as though the commands were running directly in your terminal.

Note: The attach command will display the output of the ENTRYPOINT/CMD process. This can appear as if the attach command is hung when in fact the process may simply not be interacting with the terminal at that time.

If you want to have an interactive terminal, you want to use docker exec -ti ${container name or id} sh. Depending on the image, you may also have bash available or if it’s a distroless image, then not even sh.
