.. _database_module_usage:
=====================================
Create and use modules for a database
=====================================
To continue with this document, we recommend that you have installed
the Database service and populated your data store with images for the
type and versions of databases that you want, and that you can create
and access a database.
This example shows you how to create and apply modules to a MySQL 5.6
database and redis 3.2.6 database cluster.
Create and apply a module to a mysql database
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
#. **Create the module file and trove module**
If you wish to apply a module, you must create the module first
and register it with the trove service. A user can not directly
apply a module to a trove instance.
The module created here is a demo module called ping. It is the
basic type made for testing purposes. To create it, it is as
simple as the following :command: ``echo`` command:
.. code-block:: console
$ echo "message=Module.V1" > ping1.dat
You can create a test module and mysql database with the module
applied by doing the following:
.. code-block:: console
$ trove module-create mymod ping ping1.dat --live_update \
--datastore mysql

.. _show_and_list_modules:
#. **Show and list modules**
You can view the modules on your instance by doing the following:
.. code-block:: console
$ trove module-query myinst
+-------+------+-----------+---------+--------+-----------+------------------------+------------------------+
| Name | Type | Datastore | Version | Status | Message | Created | Updated |
+-------+------+-----------+---------+--------+-----------+------------------------+------------------------+
| mymod | ping | all | all | OK | Module.V1 | 2017-06-02 17:23:40.50 | 2017-06-02 17:23:40.50 |
+-------+------+-----------+---------+--------+-----------+------------------------+------------------------+
You can count the instances each module is applied to by doing the
following:
.. code-block:: console
$ trove module-instance-count mymod
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| Module Name | Min Updated Date | Max Updated Date | Module MD5 | Current | Count |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| mymod | 2017-06-02T17:22:25 | 2017-06-02T17:22:25 | 7f700cc7b99606615f8b51946f6d3228 | True | 1 |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
You can list the instances that have a particular module applied
by doing the following:
.. code-block:: console
$ trove module-instances mymod
+--------------------------------------+--------+-----------+-------------------+--------+-----------+------+-----------+----------------------------------+
| ID | Name | Datastore | Datastore Version | Status | Flavor ID | Size | Region | Tenant ID |
+--------------------------------------+--------+-----------+-------------------+--------+-----------+------+-----------+----------------------------------+

+--------------------------------------+--------+-----------+-------------------+--------+-----------+------+-----------+----------------------------------+
Updating and creating a second module for a redis cluster
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To update a module you should have another file ready to update the
module with:
.. code-block:: console
$ echo "message=Module.V2" > ping2.dat
$ trove module-update mymod --file ping2.dat
+----------------------+--------------------------------------+
| Property | Value |
+----------------------+--------------------------------------+
| apply_order | 5 |
| auto_apply | False |
| created | 2017-06-02T17:06:21 |
| datastore | all |
| datastore_id | None |
| datastore_version | all |
| datastore_version_id | None |
| description | None |
| id | 0065a8ed-0668-4db5-a4ad-d88d0a166388 |
| is_admin | True |
| live_update | True |
| md5 | ba7c204979c8de54be6efb70a17d40b9 |
| name | mymod |
| priority_apply | False |
| tenant | eac1e46e5f7840e39012aff46a92073a |

| type | ping |
| updated | 2017-06-02T17:56:12 |
| visible | True |
+----------------------+--------------------------------------+
Now to show the usage with a redis cluster, create as follows:
.. code-block:: console
$ trove cluster-create myclust redis 3.2.6 \
--instance=flavor=15,volume=1,module=mymod \
--instance=flavor=15,volume=1,module=mymod \
--instance=flavor=15,volume=1,module=mymod
+-------------------+--------------------------------------+
| Property | Value |
+-------------------+--------------------------------------+
| created | 2017-06-02T18:00:17 |
| datastore | redis |
| datastore_version | 3.2.6 |
| id | e4d91ca6-5980-430c-94d0-bf7abc63f712 |
| instance_count | 3 |
| name | myclust |
| task_description | Building the initial cluster. |
| task_name | BUILDING |
| updated | 2017-06-02T18:00:17 |
+-------------------+--------------------------------------+
The original :command: ``count`` command will show the first instance,
unless the ``--include_clustered`` option is used. You can see the
MD5 from each applied module, and you know that the single instance
one is not current.
.. code-block:: console
$ trove module-instance-count mymod
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| Module Name | Min Updated Date | Max Updated Date | Module MD5 | Current | Count |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| mymod | 2017-06-02T17:22:25 | 2017-06-02T17:22:25 | 7f700cc7b99606615f8b51946f6d3228 | False | 1 |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
$ trove module-instance-count mymod --include_clustered
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| Module Name | Min Updated Date | Max Updated Date | Module MD5 | Current | Count |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| mymod | 2017-06-02T17:22:25 | 2017-06-02T17:22:25 | 7f700cc7b99606615f8b51946f6d3228 | False | 1 |
| mymod | 2017-06-02T18:00:18 | 2017-06-02T18:00:18 | ba7c204979c8de54be6efb70a17d40b9 | True | 3 |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
Update the module again. By doing this, it will cause the instances
to report their module is not current.
.. code-block:: console
$ echo "message=Module.V3" > ping3.dat
$ trove module-update mymod --file ping3.dat
+----------------------+--------------------------------------+

+-------------+---------------------+---------------------+----------------------------------+---------+-------+
To update an instance in a cluster you can use the
:command:`trove module-apply` command:
.. code-block:: console
$ trove cluster-instances myclust
+--------------------------------------+------------------+-----------+------+--------+
| ID | Name | Flavor ID | Size | Status |
+--------------------------------------+------------------+-----------+------+--------+

+--------------------------------------+------------------+-----------+------+--------+
$ trove module-apply 393462d5-906d-4214-af0d-538b7f618b2d mymod
+-------+------+-----------+---------+--------+-----------+

+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| Module Name | Min Updated Date | Max Updated Date | Module MD5 | Current | Count |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| mymod | 2017-06-02T17:22:25 | 2017-06-02T17:22:25 | 7f700cc7b99606615f8b51946f6d3228 | False | 1 |
| mymod | 2017-06-02T18:00:18 | 2017-06-02T18:00:18 | ba7c204979c8de54be6efb70a17d40b9 | False | 2 |
| mymod | 2017-06-02T18:18:37 | 2017-06-02T18:18:37 | 869744bdd18e306a96c145df562065ab | True | 1 |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
For variety in this example, create one more instance and module:
.. code-block:: console
$ trove create myinst_2 15 --size 1 --module mymod
+-------------------------+--------------------------------------+
| Property | Value |
+-------------------------+--------------------------------------+
| created | 2017-06-02T18:21:56 |

+-------------------------+--------------------------------------+
$ echo "message=Module.V4" > ping4.dat
$ trove module-update mymod --file ping4.dat
+----------------------+--------------------------------------+

+----------------------+--------------------------------------+
Now we have 2 single instances, and 3 cluster instances on various
versions of the module, none current.
.. code-block:: console
$ trove list
+--------------------------------------+----------+-----------+-------------------+--------+-----------+------+-----------+
| ID | Name | Datastore | Datastore Version | Status | Flavor ID | Size | Region |

+--------------------------------------+----------+-----------+-------------------+--------+-----------+------+-----------+
$ trove module-instance-count mymod --include_clustered
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| Module Name | Min Updated Date | Max Updated Date | Module MD5 | Current | Count |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| mymod | 2017-06-02T17:22:25 | 2017-06-02T17:22:25 | 7f700cc7b99606615f8b51946f6d3228 | False | 1 |
| mymod | 2017-06-02T18:00:18 | 2017-06-02T18:00:18 | ba7c204979c8de54be6efb70a17d40b9 | False | 2 |
| mymod | 2017-06-02T18:18:37 | 2017-06-02T18:21:57 | 869744bdd18e306a96c145df562065ab | False | 2 |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
When the latest module was created, the ``--include_clustered`` was
not used. Use the :command:`trove module-reapply` command:
.. code-block:: console
$ trove module-reapply mymod --md5=869744bdd18e306a96c145df562065ab --include_clustered
$ trove module-instance-count mymod --include_clustered
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| Module Name | Min Updated Date | Max Updated Date | Module MD5 | Current | Count |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| mymod | 2017-06-02T17:22:25 | 2017-06-02T17:22:25 | 7f700cc7b99606615f8b51946f6d3228 | False | 1 |
| mymod | 2017-06-02T18:00:18 | 2017-06-02T18:00:18 | ba7c204979c8de54be6efb70a17d40b9 | False | 2 |
| mymod | 2017-06-02T18:38:48 | 2017-06-02T18:38:48 | 6e2c81c1547d640b4c6e7752ed0e33ab | True | 2 |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
Now they are both updated. If the ``--force`` flag is used, it can
reapply to already applied instances. Notice that the only thing that
changes is the minimum and maximum updated date fields.
.. code-block:: console
$ trove module-reapply mymod --md5=6e2c81c1547d640b4c6e7752ed0e33ab --include_clustered --force
$ trove module-instance-count mymod --include_clustered
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| Module Name | Min Updated Date | Max Updated Date | Module MD5 | Current | Count |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| mymod | 2017-06-02T17:22:25 | 2017-06-02T17:22:25 | 7f700cc7b99606615f8b51946f6d3228 | False | 1 |
| mymod | 2017-06-02T18:00:18 | 2017-06-02T18:00:18 | ba7c204979c8de54be6efb70a17d40b9 | False | 2 |
| mymod | 2017-06-02T18:40:45 | 2017-06-02T18:40:46 | 6e2c81c1547d640b4c6e7752ed0e33ab | True | 2 |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
To bring every instance to the current version, use some of the
optional arguments to control how many instances are updated at the
same time. This is useful to avoid potential network issues, if the
module payload is large. Since we are not using the ``--force`` flag,
the minimum updated date will not change.
.. code-block:: console
$ trove module-reapply mymod --include_clustered --batch_size=1 --delay=3
$ trove module-instance-count mymod --include_clustered
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| Module Name | Min Updated Date | Max Updated Date | Module MD5 | Current | Count |
+-------------+---------------------+---------------------+----------------------------------+---------+-------+
| mymod | 2017-06-02T18:40:45 | 2017-06-02T18:44:10 | 6e2c81c1547d640b4c6e7752ed0e33ab | True | 5 |

levels, and automates complex administrative tasks such as deployment,
configuration, patching, backups, restores, and monitoring.
You can modify various cluster characteristics by editing the
``/etc/trove/trove.conf`` file. A comprehensive list of the Database
service configuration options is described in the `Database service
<https://docs.openstack.org/ocata/config-reference/database.html>`_
chapter in the *Configuration Reference*.
Create datastore

Create a data store
~~~~~~~~~~~~~~~~~~~
An administrative user can create data stores for a variety of
databases.
An administrative user can create datastores for a variety of databases.
This section assumes you do not yet have a MySQL data store, and shows
you how to create a MySQL data store and populate it with a MySQL 5.5
data store version.
.. note::
From Victoria release, all the datastores can be configured with a same
Glance image but with different datastore name and version number.
**To create a data store**
#. **Create a trove image**
Create an image for the type of database you want to use, for
example, MySQL, MongoDB, Cassandra.
This image must have the trove guest agent installed, and it must
have the ``trove-guestagent.conf`` file configured to connect to
your OpenStack environment. To configure ``trove-guestagent.conf``,
add the following lines to ``trove-guestagent.conf`` on the guest
instance you are using to build your image:
.. code-block:: ini
rabbit_host = controller
rabbit_password = RABBIT_PASS

This example assumes you have created a MySQL 5.5 image called
``mysql-5.5.qcow2``.
.. important::
If you have a guest image that was created with an OpenStack version
before Kilo, modify the guest agent init script for the guest image to
read the configuration files from the directory ``/etc/trove/conf.d``.
For a backwards compatibility with pre-Kilo guest instances, set the
database service configuration options ``injected_config_location`` to
``/etc/trove`` and ``guest_info`` to ``/etc/guest_info``.
Refer to `Build images using trovestack
<https://docs.openstack.org/trove/latest/admin/building_guest_images.html#build-images-using-trovestack>`_
#. **Register image with Image service**
You need to register your guest image with the Image service.
In this example, you use the :command:`openstack image create`
command to register a ``mysql-5.5.qcow2`` image.
You need to register your guest image with the Image service as cloud admin.

Data store classifications
--------------------------
The Database service supports a variety of both relational and
non-relational database engines, but to a varying degree of support for
each *data store*. The Database service project has defined
several classifications that indicate the quality of support for each
data store. Data stores also implement different extensions.
An extension is called a *strategy* and is classified similar to
data stores.
Valid classifications for a data store and a strategy are:
* Experimental
* Technical preview
* Stable
Each classification builds on the previous one. This means that a data store
that meets the ``technical preview`` requirements must also meet all the
requirements for ``experimental``, and a data store that meets the ``stable``
requirements must also meet all the requirements for ``technical preview``.
**Requirements**
* Experimental
A data store is considered to be ``experimental`` if it meets these criteria:
* It implements a basic subset of the Database service API including
``create`` and ``delete``.
* It has guest agent elements that allow guest agent creation.
* It has a definition of supported operating systems.
* It meets the other
`Documented Technical Requirements <https://specs.openstack.org/openstack/trove-specs/specs/kilo/experimental-datastores.html#requirements>`_.
A strategy is considered ``experimental`` if:
* It meets the
`Documented Technical Requirements <https://specs.openstack.org/openstack/trove-specs/specs/kilo/experimental-datastores.html#requirements>`_.
* Technical preview
A data store is considered to be a ``technical preview`` if it meets the
requirements of ``experimental`` and further:
* It implements APIs required to plant and start the capabilities of the
data store as defined in the
`Datastore Compatibility Matrix <https://wiki.openstack.org/wiki/Trove/DatastoreCompatibilityMatrix>`_.
.. note::
It is not required that the data store implements all features like
resize, backup, replication, or clustering to meet this classification.
* It provides a mechanism for building a guest image that allows you to
exercise its capabilities.
* It meets the other
`Documented Technical Requirements <https://specs.openstack.org/openstack/trove-specs/specs/kilo/experimental-datastores.html#requirements>`_.
.. important::
A strategy is not normally considered to be ``technical
preview``.
* Stable
A data store or a strategy is considered ``stable`` if:
* It meets the requirements of ``technical preview``.
* It meets the other
`Documented Technical Requirements <https://specs.openstack.org/openstack/trove-specs/specs/kilo/experimental-datastores.html#requirements>`_.
**Initial Classifications**
The following table shows the current classification assignments for the
different data stores.
.. list-table::

Redis data store replication
----------------------------
Replication strategies are available for Redis with
several commands located in the Redis data store
manager:
- :command:`create`
- :command:`detach-replica`
- :command:`eject-replica-source`
- :command:`promote-to-replica-source`
Additional arguments for the :command:`create` command
include :command:`--replica_of` and
:command:`--replica_count`.
Redis integration and unit tests
--------------------------------
Unit tests and integration tests are also available for
Redis.
#. Install trovestack:
.. code-block:: console
$ ./trovestack install
.. note::
Trovestack is a development script used for integration
testing and Database service development installations.
Do not use Trovestack in a production environment. For
more information, see `the Database service
developer docs <https://docs.openstack.org/developer/trove/dev/install.html#running-trovestack-to-setup-trove>`_
#. Start Redis:
.. code-block:: console
$ ./trovestack kick-start redis
#. Run integration tests:
.. code-block:: console
$ ./trovestack int-tests --group=replication
You can run :command:`--group=redis_supported`
instead of :command:`--group=replication` if needed.
Configure a cluster
~~~~~~~~~~~~~~~~~~~
An administrative user can configure various characteristics of a
MongoDB cluster.
**Query routers and config servers**
**Background.** Each cluster includes at least one query router and
one config server. Query routers and config servers count against your
quota. When you delete a cluster, the system deletes the associated
query router(s) and config server(s).
**Configuration.** By default, the system creates one query router and
one config server per cluster. You can change this by editing
the ``/etc/trove/trove.conf`` file. These settings are in the
``mongodb`` section of the file:
.. list-table::
:header-rows: 1
:widths: 30 30
* - Setting
- Valid values are:
* - num_config_servers_per_cluster
- 1 or 3
* - num_query_routers_per_cluster
- 1 or 3
