DESCRIPTION

18       Run a process in a running container.
19
20
21       The command started using docker exec will only run while the
22       container's primary process (PID 1) is running, and will not be
23       restarted if the container is restarted.
24
25
26       If the container is paused, then the docker exec command will wait
27       until the container is unpaused, and then run

OPTIONS

32       -d, --detach=true|false
33          Detached mode: run command in the background. The default is false.
34
35
36       --detach-keys=""
37         Override the key sequence for detaching a container. Format is a
38       single character [a-Z] or ctrl-<value> where <value> is one of: a-z, @,
39       ^, [, , or _.
40
41
42       -e, --env=[]
43          Set environment variables
44
45
46       This option allows you to specify arbitrary environment variables that
47       are available for the command to be executed.
48
49
50       --help
51         Print usage statement
52
53
54       -i, --interactive=true|false
55          Keep STDIN open even if not attached. The default is false.
56
57
58       --privileged=true|false
59          Give the process extended Linux capabilities
60       ⟨http://man7.org/linux/man-pages/man7/capabilities.7.html⟩ when running
61       in a container. The default is false.
62
63
64       Without this flag, the process run by docker exec in a running
65       container has the same capabilities as the container, which may be
66       limited. Set --privileged to give all capabilities to the process.
67
68
69       -t, --tty=true|false
70          Allocate a pseudo-TTY. The default is false.
71
72
73       -u, --user=""
74          Sets the username or UID used and optionally the groupname or GID
75       for the specified command.
76
77
78       The followings examples are all valid:
79          --user [user | user:group | uid | uid:gid | user:gid | uid:group ]
80
81
82       Without this argument the command will be run as root in the container.
83
84
85       The -t option is incompatible with a redirection of the docker client
86       standard input.
