<span class='quote'>Published at 2016-04-09T18:29:47+01:00</span><br />
<br />
<span>Over the last couple of years I wrote quite a few Puppet modules in order to manage my personal server infrastructure. One of them manages FreeBSD Jails and another one ZFS file systems. I thought I would give a brief overview in how it looks and feels.</span><br />

<h2 style='display: inline' id='zfs'>ZFS</h2><br />
<br />
<span>The ZFS module is a pretty basic one. It does not manage ZFS pools yet as I am not creating them often enough which would justify implementing an automation. But let's see how we can create a ZFS file system (on an already given ZFS pool named ztank):</span><br />
<br />
<span>Puppet snippet:</span><br />
<br />
<pre>
zfs::create { 'ztank/foo':
ensure => present,
filesystem => '/srv/foo',
require => File['/srv'],
}
</pre>
<br />
<span>Puppet run:</span><br />
<br />
<pre>

admin alphacentauri:~ [1215]%
</pre>
<br />
<span>The destruction of the file system just requires to set "ensure" to "absent" in Puppet:</span><br />
<br />
<pre>
zfs::create { 'ztank/foo':
ensure => absent,
filesystem => '/srv/foo',
require => File['/srv'],
}¬

<h2 style='display: inline' id='jails'>Jails</h2><br />
<br />
<span>Here is an example in how a FreeBSD Jail can be created. The Jail will have its own public IPv6 address. And it will have its own internal IPv4 address with IPv4 NAT to the internet (this is due to the limitation that the host server only got one public IPv4 address which requires sharing between all the Jails).</span><br />
<br />
<span>Furthermore, Puppet will ensure that the Jail will have its own ZFS file system (internally it is using the ZFS module). Please notice that the NAT requires the packet filter to be setup correctly (not covered in this blog post).</span><br />
<br />
<pre>
include jail::freebsd
# Cloned interface for Jail IPv4 NAT
freebsd::rc_config { 'cloned_interfaces':
value => 'lo1',
}
freebsd::rc_config { 'ipv4_addrs_lo1':
value => '192.168.0.1-24/24'
}
freebsd::ipalias { '2a01:4f8:120:30e8::17':
ensure => up,
proto => 'inet6',
preflen => '64',
interface => 're0',
aliasnum => '8',
}
class { 'jail':
ensure => present,
jails_config => {
sync => {
'_ensure' => present,
'_type' => 'freebsd',
'_mirror' => 'ftp://ftp.de.freebsd.org',
'_remote_path' => 'FreeBSD/releases/amd64/10.1-RELEASE',
'_dists' => [ 'base.txz', 'doc.txz', ],
'_ensure_directories' => [ '/opt', '/opt/enc' ],
'_ensure_zfs' => [ '/sync' ],
'host.hostname' => "'sync.ian.buetow.org'",
'ip4.addr' => '192.168.0.17',
'ip6.addr' => '2a01:4f8:120:30e8::17',
},
}
}
</pre>
<br />
<span>This is how the result looks like:</span><br />

<span>To automatically setup the applications running in the Jail I am using Puppet as well. I wrote a few scripts which bootstrap Puppet inside of a newly created Jail. It is doing the following:</span><br />
<br />
<ul>
<li>Mounts an encrypted container (containing a secret Puppet manifests [git repository])</li>
<li>Activates "pkg-ng", the FreeBSD binary package manager, in the Jail</li>
<li>Installs Puppet plus all dependencies in the Jail</li>
<li>Updates the Jail via "freebsd-update" to the latest version</li>
<li>Restarts the Jail and invokes Puppet.</li>
<li>Puppet then also schedules a periodic cron job for the next Puppet runs.</li>
</ul><br />

<br />
<span>Of course I am operating multiple Jails on the same host this way with Puppet:</span><br />
<br />
<ul>
<li>A Jail for the MTA</li>
<li>A Jail for the Webserver</li>
<li>A Jail for BIND DNS server</li>
<li>A Jail for syncing data forth and back between various servers</li>
<li>A Jail for other personal (experimental) use</li>
<li>...etc</li>
</ul><br />
<span>All done in a pretty automated manor. </span><br />
