Purpose

This page provides instructions on how to configure the Federated Cloud Production resource-BDII.

Installation

Documentation and general installation guidelines for the cloud-info-provider are available at https://github.com/EGI-FCTF/cloud-bdii-provider

If you don't have already a BDII-site service in production, you will need to install also the bdii package (available in EPEL repo).

If you are using OpenStack as provider, you also need to install the python-novaclient package.

If you want to install from packages, here follow some guidelines.

RHEL/CentOS/ScientificLinux

wget http://repository.egi.eu/community/software/cloud.info.provider/0.x/releases/repofiles/sl-6-x86_64.repo \
   -O /etc/yum.repos.d/cloud-info-provider.repo
  • Install the package
yum install cloud-info-provider-service

For Debian/Ubuntu 6/7/8

  • Add AppDB's repository:
sudo wget http://repository.egi.eu/community/software/cloud.info.provider/0.x/releases/repofiles/ubuntu-precise-amd64.list \
        -O /etc/apt/sources.list.d/cloud-info-provider.list
  • Add AppDB key:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E2E992EB352D3E14
  • Install the package
sudo apt-get update
sudo apt-get install python-cloud-info-provider

Configuration

Use one of the template files in /etc/cloud-info-provider as basis for creating your own YAML file with the static information of your resources. E.g:

cp /etc/cloud-info-provider/sample.openstack.yaml /etc/cloud-info-provider/bdii.yaml

Each middleware has its own options to fetch the dynamic information, check the --help option for more information. Some additional notes are given in the following sections.

General

  • Site name will be fetched from site -> name in the template file. Set it to the name defined in GOCDB. Alternatively, the site name can be fetched from /etc/glite-info-static/site/site.cfg (or by the file set with the --glite-site-info-static option)

OpenNebula

  • Use the --middleware opennebularocci option to activate this provider
  • Use the sample.opennebularocci.yaml configuration sample. Change the following lines:
site:
    # Your site name, as in GODCB (if omitted or set to None, this value is
    # retreived from /etc/glite-info-static/site/site.cfg )
    #name: SITE_NAME
compute:
    # Total number of cores available
    total_cores: 0
    # Total RAM available (GB)
    total_ram: 0
    # Hypervisor name (e.g. KVM, Xen, etc.)
    hypervisor: Foo Hypervisor
    # Hypervisor version
    hypervisor_version: 0.0.0
    # ...
    # Middleware version
    middleware_version: 0.0
    endpoints:
        # ...

        # Host serving your Virtual Machine Management interface (rOCCI-server)
        https://cloud-service01.example.org:11443:
            endpoint_url: https://cloud-service01.example.org:11443
    # Images are retreived automatically by the endpoint
    images:
        defaults:
            #...
            # os_tpl schema prefix must match ROCCI_SERVER_OPENNEBULA_SCHEMA_NAMESPACE in rOCCI-server, only the host part
            schema: http://schemas.cloud-service01.example.org/occi/infrastructure/os_tpl
  • You need to specify connection parameters to the OpenNebula XML-RPC interface:
    • --on-auth parameter should contain the authorization parameters for an existing user with full read permissions on the image disks. If the user has been created with the core driver, this parameter shall be set to <username>:<password>.
    • --on-rpcxml-endpoint shall contain the address of the RPCv2 endpoint. Usually it is http://<hostname>:2633/RPC2. If not on a secure network, it is suggested to provide this interface via https, since the on-auth parameter will be sent in clear text to the server.
  • Compute templates can be gathered in two ways. One option does not preclude the other and the resulting templates will be the merge of the two.
    • directly from remote OpenNebula (with rOCCI-server installed and configured), by setting the --rocci-remote-templates flag
    • manually by placing them in the configuration file
  • With the --cloudkeeper-images flag, OS templates can be filtered so only the cloudkeeper ones are published.

OpenStack

  • Use the --middleware openstack option to activate this provider
  • The OpenStack provider uses python-novaclient (needs to be installed separately)
    • --os-username, --os-password, --auth-tenant-name, --os-auth-url, --os-cacert, --insecure options to the cloud-provider allow to set the connection parameters. Alternatively you can use environment variables (e.g. OS_USERNAME) as with other OpenStack clients
    • --insecure should not be used in production!
  • Be sure that keystone contains the OCCI endpoint, otherwise it will not be published by the BDII. You can check this via the command keystone service-list. To create a new service and endpoint, you can run
keystone service-create --name occi_api --type occi --description 'Nova OCCI Service'

keystone endpoint-create --service_id <service-id> --region RegionOne --publicurl http://$HOSTNAME:8787/ \
                                         --internalurl http://$HOSTNAME:8787/ --adminurl http://$HOSTNAME:8787/

where the service-id is the one obtained from keystone service-list.

  • By default, the provider script will filter images without marketplace uri defined into the marketplace or vmcatcher_event_ad_mpuri property. If you want to list all the images templates (included local snapshots), set the variable 'require_marketplace_id: false' under 'compute' -> 'images' -> 'defaults' in the YAML configuration file.

Create the provider

  • Create the file /var/lib/bdii/gip/provider/cloud-info-provider that calls the provider with the correct options for your site, for example:
#!/bin/sh

cloud-info-provider-service --yaml /etc/cloud-info-provider/openstack.yaml \
                            --middleware openstack \
                            --os-username <username> --os-password <passwd> \
                            --os-tenant-name <tenant> --os-auth-url <url>
  • Give execution permission:
chmod +x /var/lib/bdii/gip/provider/cloud-info-provider
  • and test it:
/var/lib/bdii/gip/provider/cloud-info-provider
  • That should return the complete LDIF describing your site. Now you can start the bdii service
service bdii start
  • And check that the information is being published
ldapsearch -x -h localhost -p 2170 -b o=glue

Add your resource BDII to the site-BDII

Add your cloud-info-provider to your site-BDII by adding a new URL like this:

ldap://<cloud-info-provier-hostname>:2170/GLUE2GroupID=cloud,o=glue

Check how to set up your Site-BDII at MAN01 How to publish Site Information for information on how to add the URL.
