|
||||
OPTIONAL PARAMETERS
|
||||
-------------------
|
||||
started::
|
||||
Either "true" or "false."
|
||||
name::
|
||||
The name of the jail. Default is to use the object_id as the jail name.
|
||||
|
||||
started::
|
||||
Either "true" or "false." Defaults to true.
|
||||
|
||||
ip::
|
||||
The ifconfig style IP/netmask combination to use for the jail guest. If
|
||||
the state parameter is "present," this parameter is required.
|
||||
|
||||
hostname::
|
||||
The FQDN to use for the jail guest. Defaults to the name parameter.
|
||||
|
||||
interface::
|
||||
The name of the physical interface on the jail server to bind the jail to.
|
||||
|
||||
devfs-enable::
|
||||
Whether to allow devfs mounting within the jail. Must be "true" or "false."
|
||||
Defaults to true.
|
||||
|
||||
devfs-ruleset::
|
||||
The name of the devfs ruleset to associate with the jail. Defaults to
|
||||
"jailrules." This ruleset must be copied to the server via another type.
|
||||
To use this option, devfs-enable must be "true."
|
||||
|
||||
onboot::
|
||||
Whether to add the jail to rc.conf's jail_list variable. Must be either
|
||||
"true" or "false." Defaults to false.
|
||||
|
||||
|
||||
CAVEATS
|
||||
-------
|
||||
This type does not currently support modification of jail options. If, for
|
||||
example a jail needs to have its IP address or netmask changed, the jail must
|
||||
be removed then re-added with the correct IP address/netmask or the appropriate
|
||||
line (jail_<name>_ip="...") modified within rc.conf through some alternate
|
||||
means.
|
||||
|
||||
EXAMPLES
|
||||
--------
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
# Create a jail called www
|
||||
__jail www --state present
|
||||
__jail www --state present --ip "192.168.1.2 netmask 255.255.255.0"
|
||||
|
||||
# Remove the jail called www
|
||||
__jail www --state absent
|
||||
|
||||
# Ensure that the jail called www is started
|
||||
__jail www --state present --started true
|
||||
__jail www --state present --started true \
|
||||
--ip "192.168.1.2 netmask 255.255.255.0"
|
||||
|
||||
# Use the name variable explicitly
|
||||
__jail thisjail --state present --name www
|
||||
__jail thisjail --state present --name www \
|
||||
--ip "192.168.1.2 netmask 255.255.255.0"
|
||||
|
||||
# Go nuts
|
||||
__jail lotsofoptions --state present --name testjail --started true \
|
||||
--ip "192.168.1.100 netmask 255.255.255.0" \
|
||||
--hostname "testjail.example.com" --interface "em0" \
