Hello,

I was not able to find information about how CentOS is building its Cloud Images.

I know packer etc are able to do it, but I am interested in how CentOS is building its own images as we like to adapt that for our Openstack Cloud.

thanks for any hints

Hi, not the direct answer to your question, but as you wrote about welcome hints...

couldn't it be simpler to take one of the images officially provided by the CentOS project and then use one of:

1) diskimage-builder https://docs.openstack.org/diskimage-builder/latest/

2) guestfish / guestmount https://docs.openstack.org/image-guide/modify-images.html

3) virt-customize https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/htm...

Or do you have any particular needs? Gianluca
