<h3>Method Details</h3>
<div class="method">
<code class="details" id="create">create(parent, body=None, x__xgafv=None)</code>
<pre>Creates an instance and begins preparing it to begin serving. The
returned long-running operation
can be used to track the progress of preparing the new
instance. The instance name is assigned by the caller. If the
named instance already exists, `CreateInstance` returns
`ALREADY_EXISTS`.
Immediately upon completion of this request:
* The instance is readable via the API, with all requested attributes
but no allocated resources. Its state is `CREATING`.
Until completion of the returned operation:
* Cancelling the operation renders the instance immediately unreadable
via the API.
* The instance can be deleted.
* All other attempts to modify the instance are rejected.
Upon completion of the returned operation:
* Billing for all successfully-allocated resources begins (some types
may have lower than the requested levels).
* Databases can be created in the instance.
* The instance&#x27;s allocated resource levels are readable via the API.
* The instance&#x27;s state becomes `READY`.
The returned long-running operation will
have a name of the format `&lt;instance_name&gt;/operations/&lt;operation_id&gt;` and
can be used to track creation of the instance. The
metadata field type is
CreateInstanceMetadata.
The response field type is
Instance, if successful.
Args:
parent: string, Required. The name of the project in which to create the instance. Values
are of the form `projects/&lt;project&gt;`. (required)
body: object, The request body.
The object takes the form of:
{ # The request for CreateInstance.
&quot;instance&quot;: { # An isolated set of Cloud Spanner resources on which databases can be hosted. # Required. The instance to create. The name may be omitted, but if
# specified must be `&lt;parent&gt;/instances/&lt;instance_id&gt;`.
&quot;state&quot;: &quot;A String&quot;, # Output only. The current instance state. For
# CreateInstance, the state must be
# either omitted or set to `CREATING`. For
# UpdateInstance, the state must be

# firewall, load balancing, etc.).
#
# * Label keys must be between 1 and 63 characters long and must conform to
# the following regular expression: `[a-z]([-a-z0-9]*[a-z0-9])?`.

#
# A `Policy` is a collection of `bindings`. A `binding` binds one or more
# `members` to a single `role`. Members can be user accounts, service accounts,
# Google groups, and domains (such as G Suite). A `role` is a named list of
# permissions; each `role` can be an IAM predefined role or a user-created
# custom role.
#
# For some types of Google Cloud resources, a `binding` can also specify a
# `condition`, which is a logical expression that allows access to a resource
# only if the expression evaluates to `true`. A condition can add constraints
# based on attributes of the request, the resource, or both. To learn which
# resources support conditions in their IAM policies, see the

&quot;bindings&quot;: [ # Associates a list of `members` to a `role`. Optionally, may specify a
# `condition` that determines how and when the `bindings` are applied. Each
# of the `bindings` must contain at least one member.
{ # Associates `members` with a `role`.
&quot;role&quot;: &quot;A String&quot;, # Role that is assigned to `members`.
# For example, `roles/viewer`, `roles/editor`, or `roles/owner`.
&quot;members&quot;: [ # Specifies the identities requesting access for a Cloud Platform resource.
# `members` can have the following values:
#
# * `allUsers`: A special identifier that represents anyone who is
# on the internet; with or without a Google account.
#
# * `allAuthenticatedUsers`: A special identifier that represents anyone
# who is authenticated with a Google account or a service account.
#
# * `user:{emailid}`: An email address that represents a specific Google
# account. For example, `alice@example.com` .
#
#
# * `serviceAccount:{emailid}`: An email address that represents a service
# account. For example, `my-other-app@appspot.gserviceaccount.com`.
#
# * `group:{emailid}`: An email address that represents a Google group.
# For example, `admins@example.com`.
#
# * `deleted:user:{emailid}?uid={uniqueid}`: An email address (plus unique
# identifier) representing a user that has been recently deleted. For
# example, `alice@example.com?uid=123456789012345678901`. If the user is
# recovered, this value reverts to `user:{emailid}` and the recovered user
# retains the role in the binding.
#
# * `deleted:serviceAccount:{emailid}?uid={uniqueid}`: An email address (plus
# unique identifier) representing a service account that has been recently
# deleted. For example,
# `my-other-app@appspot.gserviceaccount.com?uid=123456789012345678901`.
# If the service account is undeleted, this value reverts to
# `serviceAccount:{emailid}` and the undeleted service account retains the
# role in the binding.
#
# * `deleted:group:{emailid}?uid={uniqueid}`: An email address (plus unique
# identifier) representing a Google group that has been recently
# deleted. For example, `admins@example.com?uid=123456789012345678901`. If
# the group is recovered, this value reverts to `group:{emailid}` and the
# recovered group retains the role in the binding.
#
#
# * `domain:{domain}`: The G Suite domain (primary) that represents all the
# users of that domain. For example, `google.com` or `example.com`.

#
# If the condition evaluates to `true`, then this binding applies to the

],
&quot;version&quot;: 42, # Specifies the format of the policy.
#
# Valid values are `0`, `1`, and `3`. Requests that specify an invalid value
# are rejected.
#
# Any operation that affects conditional role bindings must specify version
# `3`. This requirement applies to the following operations:
#
# * Getting a policy that includes a conditional role binding
# * Adding a conditional role binding to a policy
# * Changing a conditional role binding in a policy
# * Removing any role binding, with or without a condition, from a policy
# that includes conditions
#
# **Important:** If you use IAM Conditions, you must include the `etag` field
# whenever you call `setIamPolicy`. If you omit this field, then IAM allows
# you to overwrite a version `3` policy with a version `1` policy, and all of
# the conditions in the version `3` policy are lost.
#
# If a policy does not include any conditions, operations on that policy may
# specify any valid version or leave the field unset.

# To learn which resources support conditions in their IAM policies, see the
# [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).
&quot;etag&quot;: &quot;A String&quot;, # `etag` is used for optimistic concurrency control as a way to help
# prevent simultaneous updates of a policy from overwriting each other.
# It is strongly suggested that systems make use of the `etag` in the
# read-modify-write cycle to perform policy updates in order to avoid race
# conditions: An `etag` is returned in the response to `getIamPolicy`, and
# systems are expected to put that etag in the request to `setIamPolicy` to
# ensure that their change will be applied to the same version of the policy.
#
# **Important:** If you use IAM Conditions, you must include the `etag` field
# whenever you call `setIamPolicy`. If you omit this field, then IAM allows

<div class="method">
<code class="details" id="testIamPermissions">testIamPermissions(resource, body=None, x__xgafv=None)</code>
<pre>Returns permissions that the caller has on the specified instance resource.
Attempting this RPC on a non-existent Cloud Spanner instance resource will
result in a NOT_FOUND error if the user has `spanner.instances.list`
permission on the containing Google Cloud Project. Otherwise returns an
empty set of permissions.
Args:
resource: string, REQUIRED: The Cloud Spanner resource for which permissions are being tested. The format is `projects/&lt;project ID&gt;/instances/&lt;instance ID&gt;` for instance resources and `projects/&lt;project ID&gt;/instances/&lt;instance ID&gt;/databases/&lt;database ID&gt;` for database resources. (required)
body: object, The request body.
The object takes the form of:
{ # Request message for `TestIamPermissions` method.
&quot;permissions&quot;: [ # REQUIRED: The set of permissions to check for &#x27;resource&#x27;.
# Permissions with wildcards (such as &#x27;*&#x27;, &#x27;spanner.*&#x27;, &#x27;spanner.instances.*&#x27;) are not allowed.
&quot;A String&quot;,

}
x__xgafv: string, V1 error format.
Allowed values
1 - v1 error format
2 - v2 error format
Returns:
An object of the form:
{ # Response message for `TestIamPermissions` method.
&quot;permissions&quot;: [ # A subset of `TestPermissionsRequest.permissions` that the caller is
# allowed.
&quot;A String&quot;,
