lxc-start(1)
NAME
lxc-start - run an application inside a container.
SYNOPSIS
lxc-start {-n name} [-f config_file] [-c console_device] [-L
console_logfile] [-d] [-F] [-p pid_file] [-s KEY=VAL] [-C]
[--share-[net|ipc|uts] name|pid] [command]
DESCRIPTION
lxc-start runs the specified command inside the container specified by name. It will setup the container according to the configuration previously defined with the lxc-create command or with the configuration file parameter. If no configuration is defined, the default isolation is used. If no command is specified, lxc-start will use the command defined in lxc.init_cmd or if not set, the default "/sbin/init" command to run a system container.
OPTIONS
-d, --daemon
Run the container as a daemon. As the container has no more tty,
if an error occurs nothing will be displayed, the log file can
be used to check the error. (This is the default mode)
-F, --foreground
Run the container in the foreground. In this mode, the container
console will be attached to the current tty and signals will be
routed directly to the container.
-p, --pidfile pid_file
Create a file with the process id.
-f, --rcfile config_file
Specify the configuration file to configure the virtualization
and isolation functionalities for the container.
This configuration file if present will be used even if there is
already a configuration file present in the previously created
container (via lxc-create).
-c, --console console_device
Specify a device to use for the container's console, for example
/dev/tty8. If this option is not specified the current terminal
will be used unless -d is specified.
-L, --console-log console_logfile
Specify a file to log the container's console output to.
-s, --define KEY=VAL
Assign value VAL to configuration variable KEY. This overrides
any assignment done in config_file.
-C, --close-all-fds
If any file descriptors are inherited, close them. If this
option is not specified, then lxc-start will exit with failure
instead. Note: --daemon implies --close-all-fds.
--share-net name|pid
Inherit a network namespace from a name container or a pid. The
network namespace will continue to be managed by the original
owner. The network configuration of the starting container is
ignored and the up/down scripts won't be executed.
--share-ipc name|pid
Inherit an IPC namespace from a name container or a pid.
--share-uts name|pid
Inherit a UTS namespace from a name container or a pid. The
starting LXC will not set the hostname, but the container OS may
do it anyway.
COMMON OPTIONS
These options are common to most of lxc commands.
-?, -h, --help
Print a longer usage message than normal.
--usage
Give the usage message
-q, --quiet
mute on
-P, --lxcpath=PATH
Use an alternate container path. The default is /var/lib/lxc.
-o, --logfile=FILE
Output to an alternate log FILE. The default is no log.
-l, --logpriority=LEVEL
Set log priority to LEVEL. The default log priority is ERROR.
Possible values are : FATAL, CRIT, WARN, ERROR, NOTICE, INFO,
DEBUG.
Note that this option is setting the priority of the events log
in the alternate log file. It do not have effect on the ERROR
events log on stderr.
-n, --name=NAME
Use container identifier NAME. The container identifier format
is an alphanumeric string.
--rcfile=FILE
Specify the configuration file to configure the virtualization
and isolation functionalities for the container.
This configuration file if present will be used even if there is
already a configuration file present in the previously created
container (via lxc-create).
--version
Show the version number.
DIAGNOSTIC
The container is busy
The specified container is already running an application. You
should stop it before reuse this container or create a new one.
