# 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
|
|
detached 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
