| [1] | Install Heat services on Network Node. |
|
[root@network ~]# dnf --enablerepo=centos-openstack-caracal,epel,crb -y install openstack-heat-api openstack-heat-api-cfn openstack-heat-engine python3-heatclient
|
| [2] | Get valid SSL/TLS certificate or Create self-signed certificate for Network Node and Configure Heat. |
