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' fe8970c83f43b0d2d765d600239f57557edf007fe5c4501ac7cf99fe5e910e87
Attach to the container and see date changing every ten-seconds.
$ docker attach fe8970c83f43 Wed Jan 9 14:04:12 UTC 2019 Wed Jan 9 14:04:22 UTC 2019 ^C
