You can attach to the same contained process multiple times 18 simultaneously, screen sharing style, or quickly view the progress of your 19 detached process. 20 21 You can detach from the container (and leave it running) with `CTRL-p CTRL-q` 22 (for a quiet exit) or `CTRL-c` which will send a `SIGKILL` to the container. 23 When you are attached to a container, and exit its main process, the process's 24 exit code will be returned to the client. 25 26 It is forbidden to redirect the standard input of a `docker attach` command while 27 attaching to a tty-enabled container (i.e.: launched with `-t`). 28 29 # OPTIONS 30 **--help** 31 Print usage statement 32 33 **--no-stdin**=*true*|*false* 34 Do not attach STDIN. The default is *false*. 35 36 **--sig-proxy**=*true*|*false* 37 Proxy all received signals to the process (non-TTY mode only). SIGCHLD, SIGKILL, and SIGSTOP are not proxied. The default is *true*. 38 39 # EXAMPLES 40 41 ## Attaching to a container 42 43 In this example the top command is run inside a container, from an image called 44 fedora, in detached mode. The ID from the container is passed into the **docker 45 attach** command: 46 47 # ID=$(sudo docker run -d fedora /usr/bin/top -b) 48 # sudo docker attach $ID 49 top - 02:05:52 up 3:05, 0 users, load average: 0.01, 0.02, 0.05 50 Tasks: 1 total, 1 running, 0 sleeping, 0 stopped, 0 zombie 51 Cpu(s): 0.1%us, 0.2%sy, 0.0%ni, 99.7%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st 52 Mem: 373572k total, 355560k used, 18012k free, 27872k buffers 53 Swap: 786428k total, 0k used, 786428k free, 221740k cached 54 55 PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 56 1 root 20 0 17200 1116 912 R 0 0.3 0:00.03 top 57 58 top - 02:05:55 up 3:05, 0 users, load average: 0.01, 0.02, 0.05 59 Tasks: 1 total, 1 running, 0 sleeping, 0 stopped, 0 zombie 60 Cpu(s): 0.0%us, 0.2%sy, 0.0%ni, 99.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st 61 Mem: 373572k total, 355244k used, 18328k free, 27872k buffers 62 Swap: 786428k total, 0k used, 786428k free, 221776k cached 63 64 PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 65 1 root 20 0 17208 1144 932 R 0 0.3 0:00.03 top 66 67 # HISTORY 68 April 2014, Originally compiled by William Henry (whenry at redhat dot com) 69 based on docker.com source material and internal work. 70 June 2014, updated by Sven Dowideit <SvenDowideit@home.org.au>
