Re: [zones-discuss] Centralized Zone Management Tool
Ok, I've looked at the zone puppet type and have come to the conclusion that
puppet, at least in it's current form, does not what I need. At least not
without some other distributed mechanism.
The Problem is the migration of a zone from one host to another.
Such scenarios typically involve some shared storage (SAN luns in our case) for
the zone roots. Migrating a zone from host A to host B might look like this:
host A: shutdown zone
host A: unmount zone root
host A: release metaset
host B: get the zone configuration from somewhere
host B: modify the zone configuration if needed (network interfaces might have
another name)
host B: take metaset
host B: mount zone root
host B: boot zone
To manage this scenario, puppet would need to:
1) know that the zone is currently deployed on host A,
2) be able to resolve dependencies spanning multiple nodes.
For 1) there's propably a workaround which involves specifying all the zone on
all the physical nodes and use a ensure property detached or unmounted to make
sure that the zone roots of zones, which are currently deployed on another
node, are unmounted:
node A {
zone{foobar:
ensure = detached #(1
}
}
node B {
zone {foobar:
ensure = running,
require = A::Zone[foobar] #(2 This would trigger the unmounting of the
zone root
}
}
2) is more tricky because this feature doesn't exist in puppet.

Re: [zones-discuss] Centralized Zone Management Tool
Sorry to interrupt your discussion. when you are discussing Puppet, are you discussing this project http://projects.reductivelabs.com/projects/puppet or something else? thank you, Jerry Kemp On 07/10/09 07:17, Bryan Allen wrote: +-- | On 2009-07-10 04:52:59, Robert Gst??hl wrote: | | Date: Fri, 10 Jul 2009 04:52:59 PDT | From: Robert Gst??hl no-re...@opensolaris.org | To: zones-discuss@opensolaris.org | Subject: [zones-discuss] Centralized Zone Management Tool | | Hello World, | | I started to think about a centralized zone management utility / system.

Regards Robert Puppet manages zones, ZFS, NFS, and you could write providers to do the rest. Puppet is free, well-written, and has a great dev team. It's also being incorporated into many other management projects (like Cobbler), so you could say it's either already or on its way to becoming an industry standard. The DR stuff would probably be non-trivial, though in my shop I just move the zone class to another host, boot it, it mounts the data via NFS or what have you, and I'm done. ___ zones-discuss mailing list zones-discuss@opensolaris.org
