lxc-start

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, ALERT, CRIT, WARN, ERROR, NOTICE, INFO, DEBUG, TRACE.

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.
