Prerequisite :  

  • IBM Spectrum Scale 4.2.1.x
  • SSL enabled Keystone server.
  • A swift user with valid password having ‘admin‘ role in ‘service‘ tenant of ‘default‘ domain in a external Keystone server

Endpoints on External Keystone server will look like

[root@externalKeystone ~]# openstack endpoint list
| ID | Region | Service Name | Service Type | Enabled | Interface | URL |
| 78cd570651f34b848890687c4f1578a9 | None | keystone | identity | True | public | https://cesip:5000/ |
| ff82aa833eec42b7a345a1c029b74959 | None | keystone | identity | True | internal | https://cesip:35357/ |
| 692c4bb6c4a14ece9f810ba4fc1944f1 | None | keystone | identity | True | admin | https://cesip:35357/ |
| 52b559474c03454eaef67af14a3c4afe | RegionOne | swift | object-store | True | public | http://c1ces:8080/v1/AUTH_%(tenant_id)s |
| ed14c1c50f3242a0aed61b9ccdfc8c4d | RegionOne | swift | object-store | True | internal | http://c1ces:8080/v1/AUTH_%(tenant_id)s |
| f26a242b71b34128abf87cbc1e8937aa | RegionOne | swift | object-store | True | admin | http://c1ces:8080 |


On IBM Spectrum scale, Object will be already configured.
Remove the Current Object Authentication and Id-mapping using following command.

[root@c1n3 ~]# mmuserauth service remove –data-access-method object 
mmuserauth service remove: Command successfully completed

[root@c1n3 ~]# mmuserauth service remove –data-access-method object –idmapdelete
mmuserauth service remove: Command successfully completed

Copy CA-Certificates used on External Keystone server on Protocol node of IBM Spectrum Scale at following location.

[root@c1n3 ~]# ls /var/mmfs/tmp/ks_ext_cacert.pem

Run mmuserauth command on protocol node where CA-Certificate is copied

[root@c1n3 ~]# mmuserauth service create –data-access-method object –type userdefined –ks-swift-user swift –ks-swift-pwd passw0rd –ks-ext-endpoint https://cesip:5000/v3 –enable-ks-ssl
mmcesobjcrbase: Validating execution environment.
mmcesobjcrbase: Validating Keystone environment.
mmcesobjcrbase: Configuration complete.
Object authentication configuration completed successfully.

Note : External keystone server must be reachable from protocol nodes using the hostname used for creating SSL Certificates for external Keystone. Hostname in Keystone Endpoints should also match the hostname used for creating SSL certificates

IBM Spectrum scale Object is successfully configured with SSL enabled external Keystone server.

~/openrc file on protocol node will be updated with details of External Keystone.

[root@c1n3 ~]# cat openrc
export OS_AUTH_URL=”https://cesip:5000/v3
export OS_CACERT=”/etc/swift/ks_ext_cacert.pem”
export OS_USERNAME=”admin”
export OS_PASSWORD=””
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin

Update the ~/openrc with valid username and password from external Keystone server.

[root@c1n3 ~]# source ~/openrc

Verify IBM Spectrum Scale Object is working with external Keystone server.

[root@c1n3 ~]# swift stat
