This is a repository of the files/tools we are developping around
integrating the sevone (monitoring software) into RH-OSP.

This project includes several areas:
- Add policy files to the overcloud to restrict the 'readonly' role and prevent
  update/create/delete operations.
  
- Add tooling (OBSOLETE since this will be done through node-payload in the
  osp10 templates) to push/update policies on the overcloud.
  
- Provide a MOP (Method of procedure) to enable Sevone pre-requisites on
  both the undercloud and overcloud. An ASCII version of the MOP is provided
  in this repository.

This work on the 'readonly' role was a request of the VZW HQ Planning group.

Here is how it works:

On the undercloud, as the 'stack' user perform the following steps:

    1) source stackrc  
    2) git clone https://gitlab.cee.redhat.com/vcojot/OSP-Readonly-Policies/tree/master  
    3) ./policydir/files/push_readonly_policies_to_overcloud.sh  
    4) source overcloudrc
    5) openstack role create readonly

(this will auto-detect the controllers and push the appropriate policies)  

To restrict a user, then simply do add the 'readonly' role to the user, do a: 

    openstack role add --project <tenant_name> --user <user_name> readonly

To lift the restrictions and re-enable modifications to the overcloud, do a:  

    openstack role remove --project <tenant_name> --user <user_name> readonly
