How do i attach to a docker container?

Note: Control-C after attach stops the container, there is an escape sequence if running a tty.

You can attach to a container to see output for instance. Here we loop the date command to demo the docker attach command.

Create a container to loop the date command.

$ docker run -d alpine /bin/sh -c 'while x=0; do echo $(date);sleep 10;done'

Attach to the container and see date changing every ten-seconds.

$ docker attach fe8970c83f43
