'stack_hpc.os-images' role failed on RockyLinux 9 without git installed.

[Nathan Harper]

Configuring and deploying a new (2023.1) cloud on Rocky9 using stackhpc-kayobe-config, the command:

kayobe overcloud host image build

fails at task

TASK [stackhpc.os-images : Git clone any additional image element repos]

because 'git' is not present in the seed VM OS image. Installing git by hand, or by adding to dev_tools_packages_extra allows the overcloud image build to complete.

[Maksim Malchuk (mmalchuk)]

It shouldn't be installed by Kayobe itself because it is the Prerequisites for the Kayobe. Please read official documentation: https://docs.openstack.org/kayobe/latest/installation.html#prerequisites and install it yourself.

[Nathan Harper (nathharp)]

The issue is not a problem on the control host, but on the seed VM. Running:

kayobe seed vm provision
kayobe seed host configure
kayobe overcloud host image build

will fail because git is not available in the seed VM image, nor is it installed by the host configure step

[Maksim Malchuk (mmalchuk)]

These commands should be executed from the control host. Not on seed VM.

[Nathan Harper (nathharp)]

Yes, they are run on the control host. However,

kayobe overcloud host image build

executes the DIB build on the seed VM. part of that image build is pulling in extra elements via Git, which is failing because 'git' is not installed on the seed VM

[Maksim Malchuk (mmalchuk)]

please provide the detailed log file with maximum verbose enabled to see the issue.
run for example: kayobe -vvvv overcloud host image build 2>&1 | tee logfile
and attach the log file here

[Maksim Malchuk (mmalchuk)]

Looks like this is really issue, not in the Kayobe, but in the external role 'stack hpc.os-images'.
It failed only on latest RockyLinux 9 images which lack of the git package.
This can be temporary fixed by setting 'os_images_package_dependencies_extra' list variable with 'git' element.
