Synnefo

Upgrade

=======

This file documents the upgrade to newer versions of the Synnefo software.

For more information, please see deployment guide.

v0.7.4 -> v0.8

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

Synnefo is now distributed packaged in python/debian packages. You should

consider the following when migration from a previously `source` deployment

projects:

    * To keep consistency with future changes you should change ``python

      manage.py`` calls with deployed ``snf-manage`` console script.

      This includes automation scripts, service scripts etc.

      Same applies for calls to ``dispatcher.py``, ``snf-tools/admin.py``,

      ``snf-tools/burnin.py`` and ``snf-tools/cloud.py`` which are replaced

      respectively by ``snf-dispatcher``, ``snf-admin``,

      ``snf-burnin`` and ``snf-cloud``.

    * Copy custom settings files located in projects ``settings.d`` directory

      to ``/etc/synnefo/`` directory.

    * Migrate location from which :ref:`static files <static-files>` are served from.

NEW APPS

    * The 'synnefo.ui.userdata' application has been added in

      settings.d/00-apps.conf. Application urls appended in ui/urls.py.

      If no custom ROOT_URLCONF module is used, no url change is needed.

    * The new app has migrations defined.

      Use './manage.py migrate' to migrate *all* apps.

NEW/UPDATED SETTINGS

    * BYPASS_AUTHENTICATION_TOKEN_SECRET replaces BYPASS_AUTHENTICATION_TOKEN

      in settings/common/aai.py.

    * New config file 31-userdata.conf, containing userdata app settings

    * USERDATA_SSH_KEY_LENGTH in 31-userdata.conf:

      Key length in bits for generated ssh keys

    * USERDATA_SSH_KEY_EXPONENT in 31-userdata.conf:

      Generated SSH key exponent

    * USERDATA_MAX_SSH_KEYS_PER_USER in 31-userdata.conf:

      Maximum number of ssh keys a user is allowed to have

    * UI_SUPPORT_SSH_OS_LIST, in 30-ui.conf:

      A list of os names that support ssh public key assignment

    * UI_OS_DEFAULT_USER_MAP, in 30-ui.conf:

      OS/username map to identify default user name for a specific os

    * VM_CREATE_NAME_TPL, in 30-ui.conf:

      Template to be used for suggesting the user a default name for newly

      created VMs. String {0} gets replaced by the value of metadata key "os"

      for the Image.

    * UI_FLAVORS_DISK_TEMPLATES_INFO added in 30-ui.conf:

      Name/description metadata for the available flavor disk templates

    * VM_CREATE_SUGGESTED_FLAVORS in 30-ui.conf:

      Updated flavor data to include disk_template value.

    * GANETI_DISK_TEMPLATES and DEFAULT_GANETI_DISK_TEMPLATE in 20-api.conf:

      The list of disk templates supported by the Ganeti backend.

      The default template to be used when migrating Flavors with no value for

      disk_template (i.e., 'drbd').

    * UI_COMPUTE_URL, UI_GLANCE_URL in ui app:

      Configurable API endpoints

    * UI_ENABLE_GLANCE in ui app:

      Whether or not UI should retrieve images from the Glance API endpoint

      set in UI_GLANCE_API_URL. If setting is set to False, ui will request 

      images from Compute API

UI

    * synnefo.ui.userdata application has been added in INSTALLED_APPS.

      Database migration is needed for the creation of application db tables.

API

    * A new 'disk_template' attribute has been added to Flavors.

      GANETI_DISK_TEMPLATES and DEFAULT_GANETI_DISK_TEMPLATE have been added

      in 20-api.conf to control its value. A database migration is needed.

PLANKTON

    Plankton is a new image service that has been added as a separate app. The

    images are stored in backend of Pithos and thus it must be configured to

    access the DB and directory that Pithos uses to store its data. These

    settings are defined in the new plankton.py file in settings.

    Plankton stores and looks for images in the Pithos container named

    PITHOS_IMAGE_CONTAINER.

    There is a Pithos account that is reserved for system images. This account

    is defined in SYSTEM_IMAGES_OWNER.

ADMIN TOOLS

    * A new --disk-template flag has been added to snf-admin to choose a

      disk template when creating flavors. Similarly, disk_template support

      in flavors has beed added to the admin web interface.

      test suite snf-tools/burnin. Paramiko shipped with Squeeze uses

      broken RandomPool, produces warnings, see #576697.

    * snf-image must be installed on all Ganeti hosts, see README.deploy,

      Step 13.

COMPONENTS

    * snf-admin has been updated with new functionality, be sure to upgrade any

      locally installed versions.

    * snf-image replaces snf-ganeti-instance-image as the Ganeti OS provider

      used by Synnefo, and can live alongside snf-ganeti-instance-image.

      Once snf-image has been deployed on all Ganeti nodes, be sure to modify

      the value of settings.d/10-backend.conf:GANETI_CREATEINSTANCE_KWARGS

      to use 'snf-image+default'.

UI STATIC FILES

    * A major reorganization of static files has been commited. All ui and

      invitations static files has been moved in their own separate directory

      (ui/static/snf, ui/static/invitations).

    * UI static files base url is now configurable via UI_MEDIA_URL.

    * A symlink named after the current version of the ui application has been

      committed in ui/static directory. The symlink will get updated after each

      version upgrade to allow us provide unique urls of static files between

      after each upgrade, see #1460.

      defaults to MEDIA_URL + 'snf-<latest_ui_version>/'.

    * MEDIA_URL changed in 00-site.conf:

      under settings.d/ and read the relevant section in README.admin for more

      info.

v0.6.1 -> v0.6.2

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

ADMIN INTERFACE

    * The models were changed so that Flavors and SynnefoUsers now have

      a deleted state. The admin tools were updated so that models are

      now marked as deleted instead of actually being deleted from the DB.

      A database migration is needed.

      to change the type of a specific user.

RECONCILIATION

    * Implemented new reconciliation management command, please see

      ./manage.py reconcile --help and README.admin for more info.

      Recommended to run ./manage.py reconcile --detect-all periodically,

      via cron.

GANETI-INSTANCE-IMAGE

    * A new version of ganeti-instance-image is required (v0.5.1-1-snf1).

      The new version is available for download as a debian package:

      https://code.grnet.gr/projects/gnt-instance-image/files

COMPONENTS

    * snf-cyclades-gtools must be rebuilt, see snf-cyclades-gtools/debian/

      for Debian packaging.

NEW SETTINGS

    * 30-ui.conf:SUGGESTED_FLAVORS

    * 30-ui.conf:VM_IMAGE_COMMON_METADATA

      to /var/log/synnefo/dispatcher.log, redirecting stderr and stdout there

QUEUES

    * Changed default routing key naming for queues. Queues must be redeclared.

      The suggested upgrade path is to delete ALL (even obsolete) existing

      queues and restart the dispatcher. To do so, download amqp-utils from

          https://github.com/dougbarth/amqp-utils

      and run the amqp-deleteq tool for each declared queue. Alternatively,

      amqp-utils can be installed with: sudo gem install amqp-utils.

UI

    * Feedback form now uses django native send_mail for sending emails.

      Proper django settings should be set for feedback mails to work

      (https://docs.djangoproject.com/en/dev/topics/email/)
