NAME

       docker-attach - Attach to a running container

SYNOPSIS

       docker attach [--help]/ [--no-stdin[=false]] [--sig-proxy[=true]] CONTAINER

DESCRIPTION

       The  docker  attach  command  allows  you  to  attach  to  a  running  container using the
       container's ID or name, either to view its ongoing output or to control it  interactively.
       You can attach to the same contained process multiple times simultaneously, screen sharing
       style, or quickly view the progress of your daemonized process.

       You can detach from the container (and leave it running) with CTRL-p CTRL-q (for  a  quiet
       exit)  or  CTRL-c  which will send a SIGKILL to the container.  When you are attached to a
       container, and exit its main process, the process's exit code  will  be  returned  to  the
       client.

       It  is forbidden to redirect the standard input of a docker attach command while attaching
       to a tty-enabled container (i.e.: launched with -t).

OPTIONS

       --help
         Print usage statement

       --no-stdin=true|false
          Do not attach STDIN. The default is false.

       --sig-proxy=true|false
          Proxy all received signals to the process (non-TTY mode only).  SIGCHLD,  SIGKILL,  and
       SIGSTOP are not proxied. The default is true.

EXAMPLES

Attaching to a container

       In this example the top command is run inside a container, from an image called fedora, in
       detached mode. The ID from the container is passed into the docker attach command:

              # ID=$(sudo docker run -d fedora /usr/bin/top -b)
              # sudo docker attach $ID
