Support for Rocky Linux 8 was only added in Xena. See the support matrix for Victoria, Rocky Linux is not listed: https://docs.openstack.org/kolla-ansible/victoria/user/support-matrix.html

You may be able to install Docker by setting docker_yum_url to "https://download.docker.com/linux/centos", but some other configuration may break.

Hi
on Kolla ansible victoria version in bootstrap command this error is displayed:
failed to fetch key at https://download.docker.com/linux/rocky/gpg , error was: HTTP Error 404: Not Found
my compute os is rocky Linux 8 and it seems there is some problem with the docker repo on compute and /etc/yum.repos.d/docker.repo directory.
Please send me the link of the baseurl and gpgkey.
Thank you.
