Bug 2130362

.The `logging` RHEL System Role integration with the `firewall`, `selinux`, and `certificate` roles This enhancement enables you to integrate the `logging` role with the `firewall` role and the `selinux` role to manage port access and the `certificate` role to generate certificates. To control the port access, use the new `logging_manage_firewall` and `logging_manage_selinux` variables. Both variables are set to `false` by default and are not executed. Set them to `true` to execute the roles within the `logging` role. Note that you are responsible for managing port access for firewall and SELinux. To generate certificates, use the new `logging_certificates` variable. The variable is set to `false` by default and the `certificate` role is not executed. You can use this variable the same way you would use the `certificate_request` variable in the `certificate` role. The `logging` role will then use the `certificate` role to manage the certificates.
