poudriere jail [parameters] [options]

Parameters:
    -c            -- Create a jail
    -d            -- Delete a jail
    -i            -- Show information about a jail
    -l            -- List all available jails
    -s            -- Start a jail
    -k            -- Stop a jail
    -u            -- Update a jail
    -r newname    -- Rename a jail

Options:
    -b            -- Build the OS (for use with -m src)
    -B            -- Build the pkgbase set (for use with -b or -m git/svn/...)
    -q            -- Quiet (Do not print the header)
    -n            -- Print only jail name (for use with -l)
    -J n          -- Run buildworld in parallel with n jobs.
    -j jailname   -- Specify the jailname
    -v version    -- Specify which version of FreeBSD to install in the jail.
    -a arch       -- Indicates the TARGET_ARCH of the jail. Such as i386 or
                     amd64. Format of TARGET.TARGET_ARCH is also supported.
                     (Default: same as the host)
    -f fs         -- FS name (tank/jails/myjail) if fs is "none" then do not
                     create on ZFS.
    -K kernel     -- Build the jail with the kernel
    -M mountpoint -- Mountpoint
    -m method     -- When used with -c, overrides the default method for
                     obtaining and building the jail. See poudriere(8) for more
                     details. Can be one of:
                       'allbsd', 'ftp-archive', 'ftp', 'freebsdci', 'http',
		       'null', 'src=PATH', 'tar=PATH', 'url=URL', or
		       '{git,svn}{,+http,+https,+file,+ssh}' (e.g., 'git+https').
                     The default is '${METHOD_DEF}'.
    -P patch      -- Specify a patch to apply to the source before building.
    -S srcpath    -- Specify a path to the source tree to be used.
    -D            -- Do a full git clone without --depth (default: --depth=1)
    -t version    -- Version of FreeBSD to upgrade the jail to.
    -U url        -- Specify a url to fetch the sources (with method git and/or svn).
    -X            -- Do not build and setup native-xtools cross compile tools in jail
                     when building for a different TARGET ARCH than the host.
                     Only applies if TARGET_ARCH and HOST_ARCH are different.

Options for -d:
    -C clean      -- Clean remaining data existing in poudriere data folder.
                     See poudriere(8) for more details. Can be one of:
                       all, cache, logs, packages, wrkdirs
    -y            -- Do not prompt for confirmation when deleting a jail.

Options for -s and -k:
    -p tree       -- Specify which ports tree to start/stop the jail with.
    -z set        -- Specify which SET the jail to start/stop with.
