Solaris 11 Minimal Zone - Part 2/3

Posted in , , , , ,   with  No comments     Edit
I will start this post creating a default solaris zone, so we can see the main differences with our lightweight zone

We can see that there's no zones created in our box, we are only running the default. global zone.

jack@t4-1:/$ zoneadm list -cv
  ID NAME     STATUS   PATH       BRAND      IP
   0 global   running   /        solaris    shared

I will create the defaultzone zone

root@t4-1:/zones# zonecfg -z defaultzone
Use 'create' to begin configuring a new zone.
zonecfg:defaultzone> create
create: Using system default template 'SYSdefault'
zonecfg:defaultzone> set zonepath= /zones/defaultzone
zonecfg:defaultzone> commit
zonecfg:defaultzone> exit

root@t4-1:/zones#
root@t4-1:/zones# zoneadm -z defaultzone install
The following ZFS file system(s) have been created:
    rpool/zones/defaultzone

 done.

        Done: Installation completed in 288.340 seconds.


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

              to complete the configuration process.

I will finish the zone setup booting the zone and finishing the configuration (i will skip booting and config process to speed up the lecture of this post)

root@t4-1:/zones# zoneadm -z defaultzone boot
root@t4-1:/zones# zlogin -C defaultzone

After network setup and after finish installation, we can see our new zone

root@t4-1:/zones# zoneadm list -cv

  ID NAME         STATUS       PATH              BRAND      IP
   0 global        running       /              solaris    shared
   3 defaultzone   running  /zones/defaultzone  solaris    excl


root@t4-1:/zones# zlogin -C defaultzone
[Connected to zone 'defaultzone' console]

We can see right now some numbers about the defaultzone

N°of process running

defuser@defaultzone:~$ ps -ef | wc -l

      36

N°of pkg installed

defuser@defaultzone:~$ pkg list | wc -l

     278

N° of services running

defuser@defaultzone:~$ svcs -a | grep online | wc -l

      90

defuser@defaultzone:~$

In order to create the zone using the lightweight package group, we need to use another manifest using that group, for that we can create a new one, copying the default one and changing the group information

root@t4-1:/zones# cd /usr/share/auto_install/manifest/
root@t4-1:/usr/share/auto_install/manifest#
root@t4-1:/usr/share/auto_install/manifest# ls
ai_manifest.xml                   default.xml                       editor                            zone_default_unified_archive.xml
default.ksh.tmpl                  default_archive.xml               zone_default.xml              
root@t4-1:/usr/share/auto_install/manifest# cp zone_default.xml zone_min.xml

Now we need to edit the zone_min.xml file and change the package group entry for pkg:/group/system/solaris-minimal-server

<facet set="true">facet.locale.zh</facet>
                    <facet set="true">facet.locale.zh_CN</facet>
                    <facet set="true">facet.locale.zh_TW</facet>
                </image>
            </destination>
            <software_data action="install">
                <name>pkg:/group/system/solaris-minimal-server</name>
            </software_data>
        </software>

Now that we have done this, we can proceed to create our zone and call our new manifest (zone_min.xml)

root@t4-1:/# zonecfg -z minimalzone
Use 'create' to begin configuring a new zone.
zonecfg:minimalzone> create
create: Using system default template 'SYSdefault'
zonecfg:minimalzone> set zonepath=/zones/minimalzone
zonecfg:minimalzone> commit
zonecfg:minimalzone> exit
root@t4-1:/#

zoneadm install -z minimalzone -m /usr/share/auto_install/manifest/zone_min.xml

The following ZFS file system(s) have been created:
    rpool/zones/minimalzone

  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 /zones/minimalzone/root/var/log/zones/zoneadm.20170120T211831Z.minimalzone.install

root@t4-1:/zones# zoneadm -z minimalzone boot
root@t4-1:/zones# zlogin -C minimalzone

After network setup and after finish installation, we can see our new zone

minimalzone console login: minuser
Password:
Oracle Corporation      SunOS 5.11      11.3    September 2015
minuser@minimalzone:~$
minuser@minimalzone:~$
minuser@minimalzone:~$

Now we can see some numbers from the minimalzone

N°of process running

minuser@minimalzone:~$ ps -ef | wc -l

    28

N°of pkg installed

minuser@minimalzone:~$ pkg list | wc -l

     204

N° of services running

minuser@minimalzone:~$ svcs -a | grep online | wc -l

      80

As we can see there's no big difference between this two configuration, at least at the process and services level.

At the package level we can see a difference of 74 pkg that are not installed in the minimal server group

I will finish my conclusions and final thoughts in the 3rd and final part of this post.

Cheers

Rodolfo
