Hangs here. Ctrl+C and Ctrl+\ do not work. I had to kill the running docker process and it gave me the prompt back. This is reproducible.


(Skyflyer) #2

I second report by Aravind SV:

Same OS X build and same Docker.app build. I was testing Alpine distro:

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
alpine              3.3                 d7a513a663c1        3 weeks ago         4.798 MB
alpinist            latest              d7a513a663c1        3 weeks ago         4.798 MB

Ran the image with docker run --rm -t -i alpinist, whereas alpinist image is the same as alpine 3.3. I would also point out, that docker ps is completely unresponsive.

Restarting the docker.app fixes docker ps, but docker ps -a doesn’t work (but that’s a different error).
