Packer OpenSUSE Leap 15.4 Image in VMware for Rancher RKE2

This packer script will create an OpenSUSE Leap 15.4 Template. tergeted to be a Golden Image for RKE2 deployments.

The following is handled in the preseed file autoinst.xml

• Swap not implemented.
• Disk-1 as XFS Partition mounted under /var/lib/rancher.
• Installation of cloud-init.
• cloud-init services enablement.

Create a hashed 512-sha password for the priviledged user

The user root is employed in the script for simplicity of operations and a hashed password must be provided in the autoinst.xml file. To generate a hashed 512-sha password for this user, you can use openssl as the example below:

openssl passwd -6
Password: 
Verifying - Password: 
$6$qe3staoHstY7ptxj$.QDw8GgQE.UFUdynEkJPgPdImB//Xu3M58dOXJ.KuE.MURj0D/PxzxWvlLVn4Nfd0woBCphXt2TRxwXwJ/Ltp1

Running packer build with hcl

Rename the variables.pkrvar.hcl and populate as you see fit. run the following and enjoy your coffee :)

packer build -var-file variables.pkrvar.hcl opensuse_leap15_4_x86_64.pkr.hcl

To do

• In file install.sh there's a dirty hack to wait for 10 minutes (sleep 600) after the first boot, to allow YAST2 to complete the installation. The wait prevents the packer from shutting down the VM too soon.
