Synnefo

Upgrade to Synnefo v0.14

^^^^^^^^^^^^^^^^^^^^^^^^

The bulk of the upgrade to v0.14 is about resource and quota migrations.

.. warning::

    It is strongly suggested that you keep separate database backups

    for each service after the completion of each of step.

1. Bring web services down, backup databases

============================================

1. All web services must be brought down so that the database maintains a

   predictable and consistent state during the migration process::

    # service gunicorn stop

    # service snf-dispatcher stop

    # etc.

2. Backup databases for recovery to a pre-migration state.

3. Keep the database servers running during the migration process

2. Upgrade Synnefo and configure settings

=========================================

2.2 Sync and migrate Django DB

------------------------------

.. note::

   If you are asked about stale content types during the migration process,

   answer 'no' and let the migration finish.

::

    astakos-host$ snf-manage syncdb

    astakos-host$ snf-manage migrate quotaholder_app 0001 --fake

    astakos-host$ snf-manage migrate quotaholder_app

    astakos-host$ snf-manage migrate im

    cyclades-host$ snf-manage syncdb

    cyclades-host$ snf-manage migrate

3 Quota-related steps

=====================

3.1 Set services and resources

------------------------------

Astakos and its resources should also get registered, so that they can

be known to the quota system.

Run::

    astakos-host$ snf-manage service-add astakos service_url api_url

    astakos-host$ snf-manage resource-export-astakos > astakos.json

    astakos-host$ snf-manage resource-import --json astakos.json

    astakos-host$ snf-manage resource-modify astakos.pending_app --limit <num>

The last command will set the limit of max pending project applications

per user. This replaces setting ASTAKOS_PENDING_APPLICATION_LIMIT.

In order to migrate the user-specific limits, run

(script: ``migrate_pending_app.py``)::

    import os

    os.environ['DJANGO_SETTINGS_MODULE'] = 'synnefo.settings'

    from astakos.im.models import UserSetting, AstakosUserQuota, Resource

    SETTING = 'PENDING_APPLICATION_LIMIT'

    RESOURCE = 'astakos.pending_app'

    try:

        resource = Resource.objects.get(name=RESOURCE)

    except Resource.DoesNotExist:

        print "Resource 'astakos.pending_app' not found."

        exit()

    settings = UserSetting.objects.filter(setting=SETTING)

    for setting in settings:

        user = setting.user

        value = setting.value

        q, created = AstakosUserQuota.objects.get_or_create(

            user=user, resource=resource, capacity=value)

        if not created:

            print "Base quota already exists: %s %s" % (user.uuid, RESOURCE)

            continue

        print "Migrated base quota: %s %s %s" % (user.uuid, RESOURCE, value)

with::

    astakos-host$ python ./migrate_pending_app.py

followed by::

    astakos-host$ snf-manage reconcile-resources-astakos
