Upgrading an OpenSolaris ipkg zone

Recently I was working on my OpenSolaris machine (file server, ZFS rocks, will write more on that later), and I have one non-global zone, one that use for web development, which is aptly called dev-web.

So the following shows up when I run zoneadm:

xistence@Keyhole.network.lan:~# zoneadm list -iv
  ID NAME             STATUS     PATH                           BRAND    IP    
   0 global           running    /                              native   shared
   4 dev-web          running    /storage/zones/dev-web         ipkg     shared

The thing is, I had upgraded the global zone with the latest update available for the version (snv_101b):

pkg image-update -v

This had not upgraded my one none-global zone. And running pkg image-update from within the zone itself is not possible, because you can't do an upgrade on a "live" system, mainly because the image-update wants to create a new bootable environment, something that was already created when I upgraded the global zone. So what we have to do is mount the non-global zone to /mnt and tell pkg with -R where to find it and upgrade it anyway!

First we are going to halt the current zone, since I am mean and nothing important is running on the test bed system, I just used:

zoneadm -z dev-web halt

However, the better way is to off course use the shutdown command:

zlogin dev-web shutdown

and then for good measure a halt!

Next up, looking at what we are going to be mounting.

When pkg image-update was run on the global zone it created a new bootable environment named opensolaris-1, the cool thing is, that beadm at the same time will also create a new bootable environment for your zones. That way you can upgrade your zones afterwards, and if stuff does not work, you can revert the ENTIRE machine back to the previous state (ZFS is cool like that), thereby also making sure that your zones are reverted so that there are no incompatibilities.

So what we are looking for in this case is a zbe-1, this is the new root for the zone that we need to update, so we now need to mount it.

mount -F zfs storage/zones/dev-web/ROOT/zbe-1 /mnt

Note, that there is no / in front of storage, this is because we are specifying a pool name, since there is no "real" path that is defined as /storage/zones/dev-web/ROOT/zbe-1. Now that it is mounted, we are able to pass the -R flag to pkg, to get it to update our zone:

xistence@Keyhole.network.lan:~# pkg -R /mnt image-update -v

Voilá, and the deed is done. The last command is to off course unmount the zone, that we can then issue a zoneadm boot command to start it back up:

umount /mnt
zoneadm -z dev-web boot

And then on the zone after we log into it (over SSH in my case):

xistence@webdev.network.lan:~# pkg list -u
No installed packages have available updates

Which is exactly what we wanted! Your zone is now upgraded with the latest version available from the global zone.
