.SH DESCRIPTION
\fBiocage\fP is a system administration tool for jails designed to simplify
jail management tasks. It abstracts away the management of ZFS backed jails
running VNET or shared \fIIP\fP networking with optional support for resource
\fIlimits\fP.
.PP
Both, shared \fIIP\fP based jails and VNET enabled jails are supported.
.PP
Each jail has a unique ID (\fIUUID\fP) automatically generated at creation time.
Using the \fIUUID\fP as a jail identifier means that a jail can be replicated in a
distributed environment with greater flexibility. This also eliminates
potential naming clashes on large scale deployments and helps reduce
operator error.
.PP
Partial \fIUUID\fP calling is supported with every operation, e.g. for
"adae47cb-01a8-11e4-aa78-3c970ea3222f" the use in the form of "adae47cb" or
just "adae" works.
In addition to partial \fIUUID\fP calling, jail TAG's can be used interchangeably.
.PP
To ease jail identification a TAG field is included in \fIlist\fP mode which can
be \fIset\fP to any string (hostname, label, note, etc.). By default if unset the
TAG field contains the creation date and time stamp.
.PP
Properties are stored inside ZFS custom fields. This eliminates the need for
any configuration files and jails can be easily moved with ZFS send and
receive preserving all of their properties automatically.
.PP
\fBiocage\fP relies on ZFS and at least one ZFS pool must be present on the host
system. To enable all the features \fBiocage\fP supports, consider the following
optional kernel options and system reqiurements:
.RS
.TP
.B

FreeBSD 10.0-RELEASE amd64 or higher
.TP

bridge interfaces (bridge0,bridge1) add:

.SH SUBCOMMANDS
\fIactivate\fP \fIZPOOL\fP
.PP
.nf
.fam C
Intended for automation tools. The pool can be activated for iocage jails
without requiring user input.
.fam T
.fi
\fIcap\fP \fIUUID\fP|TAG
.PP
.nf
.fam C
Reapply resource limits on jail while it is running.
.fam T
.fi
\fIchroot\fP \fIUUID\fP|TAG [\fIcommand\fP]
.PP
.nf
.fam C
Chroot into jail, without actually starting the jail itself. Useful for
initial setup (set root password, configure networking). You can specify a
command just like with the normal system chroot tool.
.fam T
.fi
\fIclean\fP [\fB-a\fP|\fB-r\fP|\fB-j\fP]
.PP
.nf
.fam C
This removes the ZFS datasets associated with the flag called. The -a switch
will destroy everything associated with iocage. The -r switch will destroy all
releases that have been fetched. Basejails rely on these to exist, so be sure
you don't remove them if you have any. The -j switch will destroy the jails
dataset.
.fam T
.fi
\fIclone\fP \fIUUID\fP|TAG [\fIUUID\fP|TAG@\fIsnapshot\fP] [\fIproperty=value\fP]
.PP
.nf
.fam C
Clone jail identified by UUID (ZFS clone). All properties will be reset on
the clone, defaults can be overridden by specifying properties on the fly.
Custom point-in-time snapshots can be used as a source for cloning in the
form of UUID@snapshot or TAG@snapshot.
Examples:
Clone the current state of the jail:

ip4_addr="interface|ip-address/netmask"
.PP
.nf
.fam C
The IPv4 address for VNET and shared IP jails.
Form is: interface|ip-address/netmask
Multiple interfaces:
"interface|ip-address/netmask,interface|ip-address/netmask"
For shared IP jails if an interface is given before
the IP address, an alias for the address will be added to that
interface, as it is with the interface parameter. If the DEFAULT
tag is used instead of an interface, the interface will be
automatically assigned based upon the system's default interface.
If a netmask in either dotted-quad or CIDR form is given after IP
address, it will be used when adding the IP alias.
If the AUTOIP4 tag is used in place of an ip-address, the IP address
will be automatically assigned at first start of the jail. This
requires that the ip4_autostart and ip4_autoend variables are set on
the 'default' property source. If used, the IP4 address will be set
to the first available based upon the given range and already created
jails.
Example:
# iocage set ip4_autostart="100" default
# iocage set ip4_autoend="150" default
# iocage set ip4_autosubnet="24" default
This will result in the automatic IPv4 address being assigned in the
base range of the default network interface. I.E. if the local default
NIC is set to 192.168.0.XXX, then the new address will be
192.168.0.[100-150]/24
For VNET jails the interface will be configured with the IP addresses
listed.
Example: "vnet0|192.168.0.10/24,vnet1|10.1.1.10/24"
This would configure interfaces vnet0 and vnet1 in a VNET jail. In this
case no network configuration is necessary in the jail's rc.conf file.

effective and enforce_statfs is set to a value lower than 2.
Devfs rules and rulesets cannot be viewed or modified from inside

NOTE: It is important that only appropriate device nodes in devfs
be exposed to a jail; access to disk devices in the jail may permit
processes in the jail to bypass the jail sandboxing by modifying
files outside of the jail. See devfs(8) for information on
