==============================
Database instances (instances)
==============================
Creates, lists, shows details for, attaches a configuration group
to, detaches a configuration group from, deletes, lists
configuration defaults, creates root, and determines whether root
is enabled for instances.
Delete database instance
========================
.. rest_method:: DELETE /v1.0/{accountId}/instances/{instanceId}
Deletes a database instance, including any associated data.
This operation does not delete any read slaves.
You cannot complete this operation when the instance state is
either ``REBUILDING`` or ``BUILDING``.

Show database instance details
==============================
.. rest_method:: GET /v1.0/{accountId}/instances/{instanceId}
Shows database instance details.
Lists the status and details of the database instance.
Lists the volume size in gigabytes (GB) and the approximate GB
used.
After instance creation, the ``used`` value is greater than 0, which
is expected as databases may create some basic (non empty) files to
represent an empty schema. The response does not include the ``used``
attribute when the instance status is ``BUILD``, ``REBOOT``,
``RESIZE``, or ``ERROR``.
The list operations return a DNS-resolvable host name for the
database instance rather than an IP address. Because the host name
always resolves to the correct IP address for the database
instance, you do not need to maintain the mapping. Although the IP
address might change when you resize, migrate, or perform other
operations, the host name always resolves to the correct database
instance.

Attach configuration group
==========================
.. rest_method:: PUT /v1.0/{accountId}/instances/{instanceId}
Attaches a configuration group to an instance.

Detach configuration group
==========================
.. rest_method:: PUT /v1.0/{accountId}/instances/{instanceId}
Detaches a configuration group from an instance.
When you pass in only an instance ID and omit the configuration ID,
this operation detaches any configuration group that was attached
to the instance.

Detach replica
==============
.. rest_method:: PATCH /v1.0/{accountId}/instances/{instanceId}
Detaches a replica from its replication source.
If you created an instance that is a replica of a source instance,
you can detach the replica from the source. This can be useful if
the source becomes unavailable. In this case, you can detach the
replica from the source, making the replica a standalone database
instance. You can then take the new standalone instance and create
a new replica of that instance.

Create database instance
========================
.. rest_method:: POST /v1.0/{accountId}/instances
Creates a database instance.
Asynchronously provisions a database instance. You must specify a
flavor and a volume size. The service provisions the instance with
a volume of the requested size, which serves as storage for the
database instance.
**Notes**
- You can create only one database instance per POST request.
- You can create a database instance with one or more databases. You
associate users with each database.
- The port on which the database instance is listening is database
specific.
