vsphere-iso example for CentOS

[dkirrane]

Is there any vsphere-iso example for creating a vm from an ISO and Kickstart file.

[michaelhajjar]

I am currently using the following packer json file for creating centos7 template on vsphere version 6 (with no boot_cmd option, because the API does not support it).

}

You can also use the boot_cmd option if you have vsphere 6.5, otherwise you can edit the centos7 iso and edit the isolinux.cfg to point to the floppy disk(kickstart file) in this setup.

[dkirrane]

I can create a kickstart ISO that can load automatically without editing the Centos ISO. Just need to add the ks.cfg into a storage volume named OEMDRV mkisofs -V OEMDRV -o kickstart.iso ks.cfg

Can an extra CD-ROM device be added for the kickstart ISO? And can Packer remove all CD-ROM devices once install completes?

Must look at the boot_cmd option for 6.5. Could probably just pass boot option inst.ks=<location of ks.cfg>

[sudomateo]

@dkirrane I attempted to use Packer to create a CentOS image with a kickstart.iso created with mkisofs -V OEMDRV -o kickstart.iso ks.cfg successfully. The trick is to attach the kickstart.iso file as a secondary CD/DVD drive using the iso_paths parameter.

My template:

[ideologysec]

Packer does IIRC remove all CD-ROM devices when the build is finished, or at least this builder does, but only if you don't convert it to a template.

[dkirrane]

@sudomateo I've used the following steps with govc

1. My kickstart ks.cfg file Note the cmdline, poweroff, passed in network info {{}}, services enabled and post install sections were required for me. The rest is pretty standard from a normal manual install.

#version=DEVEL

# Use non-interactive command line mode
cmdline
eula --agreed
logging --level=info
selinux --disabled
firewall --disabled
poweroff

# System authorization information
auth --enableshadow --passalgo=sha512
# Use CDROM installation media
cdrom
# Run the Setup Agent on first boot
firstboot --disabled
# Keyboard layouts

# Network information

%end

%addon com_redhat_kdump --disable --reserve-mb='auto'

%end

%anaconda
pwpolicy root --minlen=6 --minquality=1 --notstrict --nochanges --notempty
pwpolicy user --minlen=6 --minquality=1 --notstrict --nochanges --notempty
pwpolicy luks --minlen=6 --minquality=1 --notstrict --nochanges --notempty
%end

#Post Install
%post --log=/root/ks-post.log
yum install -y epel-release
yum install -y open-vm-tools
yum install -y perl
%end

2. Create kickstart iso mkisofs -V OEMDRV -o kickstart.iso ks.cfg

3. Upload CentOS iso. (As downloaded. No changes needed) govc datastore.upload CentOS-7-x86_64-Minimal-1708.iso isos/CentoOS.iso

4. Upload kickstart iso govc datastore.upload kickstart.iso isos/kickstart.iso

5. Create VM (called MyVM) from CentOS ISO (do not power on, add disk, ram cpu, vlan settings also as required) govc vm.create -g=centos64Guest -on=false -iso=isos/CentoOS.iso -iso-datastore=DataStoreXYZ MyVM

6. Add CD-ROM device kickstart iso govc device.cdrom.add -vm MyVM

7. Insert kickstart iso into new CD-ROM govc device.cdrom.insert -vm MyVM -device {{kickstart_cdrom_device_num_from_step_6}} isos/kickstart.iso

8. Set boot order govc device.boot -vm MyVM -delay 1000 -order cdrom,ethernet,disk

9. Power on VM govc vm.power -on MyVM

10. Wait for kickstart to complete. At this stage you can follow the automated kickstart install from the vSphere client console To wait I retry this command until PowerState == poweredOff govc vm.info -json MyVM jq -r .VirtualMachines[].Runtime.PowerState

11. Get all CD-ROM devices numbers govc device.info -json -vm MyVM cdrom-*

12. Remove all CD-ROM devices from VM govc device.remove -vm MyVM {{kickstart_cdrom_device_num_from_step_11}} govc device.remove -vm MyVM {{centos_cdrom_device_num_from_step_11}}

13. Enable VM UUID govc vm.change -vm MyVM -e="disk.enableUUID=1"

14. Convert to template govc vm.markastemplate MyVM

Thanks for your help.

[jason-azze]

Thanks for providing some examples, friends. You saved me a ton of time while getting CentOS 7 working with vSphere 5.5.

I also had to get CentOS 6 working. Here are a few things I learned.

• CentOS 6 doesn't "know" about the OEMDRV label. So mounting a kickstart.iso alongside your installation media so it can automagically be found won't work. Instead I had to make a customized modification of CentOS-6.10-x86_64-bin-DVD1.iso by following the instructions in section "32.9.1. Creating Kickstart Boot Media" in the RHEL 6 installation guide.
• But now you have a new problem -- epel-release and open-vm-tools are not available on DVD1. Fine. You can just yum install them in the %post section of your ks.cfg. Except, /etc/resolv.conf hasn't been set up yet when the %post step runs. So yum doesn't work. After several hours of fiddling with different ideas (including constructing my own, custom "Everything" iso), I decided to construct a temporary /etc/resolv.conf during %post and then run the package installs.

%post --log=/root/ks-post.log
echo "search myinternalnamespace.com" >> /etc/resolv.conf
echo "nameserver 8.8.8.8" >> /etc/resolv.conf
yum install -y epel-release
yum install -y open-vm-tools
service vmtoolsd start
chkconfig vmtoolsd on
%end

Another CentOS 6 quirk if you are copy-and-pasting the examples here.

• CentOS 6 kickstart doesn't understand or need eula --agreed

And extra thanks to @sudomateo for the example up there ^^^. You saved me a ton of time with CentOS 7. But watch our for that "disk_size": 16,. That only gives you 16MB. It had me scratching my head for a bit. :-)

[MacFlurry]

That only gives you 16MB. It had me scratching my head for a bit. :-)

Haha , indeed. that also turned me crazy until I figured out that it was in MB. 😂😂

[MacFlurry]

for vsphere 6.5 I made Packer and Kickstart successfully work for template VM.

You're very welcome! Haha at the time of my writing, the disk_size parameter was in gigabytes. Sorry for the confusion! I'll edit my response above.

@MacFlurry Thanks very much for the snippet, that saves me a little time :)

You're welcomed :-)

inst.ks=hd:fd0:/ks.cfg

This will not work on CentOS 8+. I had to revert to http..

[ideologysec]

@kbcz1989 confirmed. I haven't had a chance to dig into why, but I think either kickstart dropped floppy support or the default vmware/floppy driver isn't included anymore.

[allaboutopensource]

i am able to spin the vm in vmware esxi 6.7 but the build is failing at "Build 'vsphere-iso' errored: Timeout waiting for SSH"

getting an error

i have given the same ssh_username, password what is there in the kickstart file but still the same . ssh_timeout is 5min .

[kbcz1989]

@allaboutopensource so, installation finishes or not? Do you see the IP address in VSphere? Can you connect manually to that IP from packer IP?

[allaboutopensource]

i can see the IP address in the vsphere with the login page showing up but i cannot ping the ip address and nor tenlet to 22 port.

[kbcz1989]

That sounds like a network problem. If you install the machine manually and set the same ip, can you then ping/telnet from packer machine?

[allaboutopensource]

i am able to create the vm with manually assigned ip address but it just taking more then 5 minutes to activate the network on it.

one more thing is that when i try to login to the vmware vm console manually with the username and password it says incorrect login.
