Creating a Zone in Solaris 11

In oracle solaris 10, zones was introduced which gave us an ability to create isolated environments for

applications that can run on a single machine. Solaris 11 has added a lot of new features to the zones

technology. Let us get started and see how we can create a zone in solaris 11.

Pre-requisites:

1.

A server with Solaris 11 installed

2.

IPS repository

3. ZFS file system to install zone (This is mandatory is Solaris 11)

Configuring the zone

First thing we need is a installation path for the new zone to be created. I am going to create a

filesystem under rpool of global zone.

root@testlab:~# zfs create rpool/zone01

Using zonecfg we will create the new zone, zone01 and assign the necessary resources through the

interactive configuration flow of zonecfg command.

root@testlab:~# zonecfg -z zone01

Use 'create' to begin configuring a new zone.

zonecfg:zone01> create

create: Using system default template 'SYSdefault'zonecfg:zone01> set zonepath=/rpool/zone01

zonecfg:zone01> set autoboot=true

zonecfg:zone01> set bootargs="-m verbose"

zonecfg:zone01> verify

zonecfg:zone01> commit

zonecfg:zone01> exit

Verify the zone we have created

root@testlab:~# zoneadm list -icvID NAME STATUS PATH BRAND IP

0 global running / solaris shared

- zone01 configured /rpool/zone01 solaris excl

Installing the zone

Before installing the zone make sure you have a IPS repository available to use as Solaris 11 uses IPS

to install the new zone by downloading the installation image from IPS repository. I have a local

repository set in my global zone.

root@testlab:~# pkg publisher

PUBLISHER TYPE STATUS P LOCATION

solaris origin online F file:///sol_11_repo/repo/

Now install the zone using below command:

root@testlab:~# zoneadm -z zone01 install

/rpool/zone01 must not be group readable.

/rpool/zone01 must not be group executable.

/rpool/zone01 must not be world readable.

/rpool/zone01 must not be world executable.

changing zonepath permissions to 0700.

Next Steps: Boot the zone, then log into the zone console (zlogin -C)

to complete the configuration process.

Log saved in non-global zone as

4/12

The zone is installed now. Check the status of the installed zone:

root@testlab:~# zoneadm list -icv

ID NAME STATUS PATH BRAND IP


- zone01 installed /rpool/zone01 solaris excl

You can also check the file systems that are created under /rpool/zone01 for the zone01.

root@testlab:~# zfs list |grep zone

rpool/zone01 414M 4.50G 32K /rpool/zone01

rpool/zone01/rpool 414M 4.50G 31K /rpool

rpool/zone01/rpool/ROOT 414M 4.50G 31K legacy

rpool/zone01/rpool/ROOT/solaris 414M 4.50G 390M /rpool/zone01/root

rpool/zone01/rpool/ROOT/solaris/var 24.3M 4.50G 23.7M /rpool/zone01/root/var

rpool/zone01/rpool/VARSHARE 31K 4.50G 31K /var/sharerpool/zone01/rpool/export 62K 4.50G 31K /export

rpool/zone01/rpool/export/home 31K 4.50G 31K /export/home

The ZFS dataset used to create the zones gives us the ability to clone the zones.

Booting the zone

Now the final step is to boot the configured, installed zone and configure the zone using the System

Configuration Tool (SCI).

root@testlab:~# zoneadm -z zone01 boot

root@testlab:~# zlogin -C zone01

[Connected to zone 'zone01' console]


5/12

The system configuration tool starts after you press enter. Use ESC + 2 to navigate through the next

screens.

Set the hostname for the zone as zone01 and mode of network configuration as manual.


6/12

On the next screen give the IP address to the NIC card net0 and a netmask.

We will not configure any DNS service so select Do not configure DNS.


7/12

Select None option for alternate name service.

On the next screens set the time zone according to your location.


8/12


9/12

Now set the root password. Also if you want any user to be created, you can do it on this screen.

Double check the system configuration summary before going forward.


10/12

After this the system will get configured. No need to login as its the console login of the zone. Use ~.

to come out of the console.

Check the status of the zone01 from the global zone. It should be running now.

root@testlab:~# zoneadm list -icv

ID NAME STATUS PATH BRAND IP


1 zone01 running /rpool/zone01 solaris excl

If you check dladm, you would see a virtual NIC created:

root@testlab:~# dladm show-link

LINK CLASS MTU STATE OVER

net0 phys 1500 up --

zone01/net0 vnic 1500 up net0

Now login to the zone

root@testlab:~# zlogin zone01

[Connected to zone 'zone01' pts/3]

root@zone01:~# uname -a

Check the network settings:

root@zone01:~# dladm show-link

root@zone01:~# ipadm show-addr

If you check zfs list, you would only see zfs dataset assigned to zone and not the global file system.

root@zone01:~# zfs list

To check the complete configuration details of the zone from non-global zone:
