Creates a new Connectivity Test. After you create a test, the reachability analysis is performed as part of the long running operation, which completes when the analysis completes. If the endpoint specifications in `ConnectivityTest` are invalid (for example, containing non-existent resources in the network, or you don't have read permissions to the network configurations of listed projects), then the reachability result returns a value of `UNKNOWN`. If the endpoint specifications in `ConnectivityTest` are incomplete, the reachability result returns a value of AMBIGUOUS. For more information, see the Connectivity Test documentation.

Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

Updates the configuration of an existing `ConnectivityTest`. After you update a test, the reachability analysis is performed as part of the long running operation, which completes when the analysis completes. The Reachability state in the test resource is updated with the new result. If the endpoint specifications in `ConnectivityTest` are invalid (for example, they contain non-existent resources in the network, or the user does not have read permissions to the network configurations of listed projects), then the reachability result returns a value of UNKNOWN. If the endpoint specifications in `ConnectivityTest` are incomplete, the reachability result returns a value of `AMBIGUOUS`. See the documentation in `ConnectivityTest` for more details.

Rerun an existing `ConnectivityTest`. After the user triggers the rerun, the reachability analysis is performed as part of the long running operation, which completes when the analysis completes. Even though the test configuration remains the same, the reachability result may change due to underlying network configuration changes. If the endpoint specifications in `ConnectivityTest` become invalid (for example, specified resources are deleted in the network, or you lost read permissions to the network configurations of listed projects), then the reachability result returns a value of `UNKNOWN`.

Sets the access control policy on the specified resource. Replaces any existing policy. Can return `NOT_FOUND`, `INVALID_ARGUMENT`, and `PERMISSION_DENIED` errors.

Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a `NOT_FOUND` error. Note: This operation is designed to be used for building permission-aware UIs and command-line tools, not for authorization checking. This operation may "fail open" without warning.

Args:
  parent: string, Required. The parent resource of the Connectivity Test to create: `projects/{project_id}/locations/global` (required)
  body: object, The request body.
    The object takes the form of:

{ # A Connectivity Test for a network reachability analysis.
  "bypassFirewallChecks": True or False, # Whether the test should skip firewall checking. If not provided, we assume false.
  "createTime": "A String", # Output only. The time the test was created.
  "description": "A String", # The user-supplied description of the Connectivity Test. Maximum of 512 characters.
  "destination": { # Source or destination of the Connectivity Test. # Required. Destination specification of the Connectivity Test. You can use a combination of destination IP address, Compute Engine VM instance, or VPC network to uniquely identify the destination location. Even if the destination IP address is not unique, the source IP location is unique. Usually, the analysis can infer the destination endpoint from route information. If the destination you specify is a VM instance and the instance has multiple network interfaces, then you must also specify either a destination IP address or VPC network to identify the destination interface. A reachability analysis proceeds even if the destination location is ambiguous. However, the result can include endpoints that you don't intend to test.

Otherwise, specify the VM instance, which already contains its internal IP address and VPC network information. If the source of the test is within an on-premises network, then you must provide the destination VPC network. If the source endpoint is a Compute Engine VM instance with multiple network interfaces, the instance itself is not sufficient to identify the endpoint. So, you must also specify the source IP address or VPC network. A reachability analysis proceeds even if the source location is ambiguous. However, the test result may include endpoints that you don't intend to test.

getIamPolicy(resource, options_requestedPolicyVersion=None, x__xgafv=None)

Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.

Args:
  resource: string, REQUIRED: The resource for which the policy is being requested. See [Resource names](https://cloud.google.com/apis/design/resource_names) for the appropriate value for this field. (required)
  options_requestedPolicyVersion: integer, Optional. The maximum policy version that will be used to format the policy. Valid values are 0, 1, and 3. Requests specifying an invalid value will be rejected. Requests for policies with any conditional role bindings must specify version 3. Policies with no conditional role bindings may specify any valid value or leave the field unset. The policy in the response might use the policy version that you specified, or it might use a lower policy version. For example, if you specify version 3, but the policy has no conditional role bindings, the response uses version 1. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies).
  x__xgafv: string, V1 error format.
    Allowed values
      1 - v1 error format
      2 - v2 error format

Returns:
  An object of the form:

    { # An Identity and Access Management (IAM) policy, which specifies access controls for Google Cloud resources. A `Policy` is a collection of `bindings`. A `binding` binds one or more `members`, or principals, to a single `role`. Principals 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 [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [ "user:mike@example.com", "group:admins@example.com", "domain:google.com", "serviceAccount:my-project-id@appspot.gserviceaccount.com" ] }, { "role": "roles/resourcemanager.organizationViewer", "members": [ "user:eve@example.com" ], "condition": { "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression": "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version": 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time < timestamp('2020-10-01T00:00:00.000Z') etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).
  "auditConfigs": [ # Specifies cloud audit logging configuration for this policy.
    { # Specifies the audit configuration for a service. The configuration determines which permission types are logged, and what identities, if any, are exempted from logging. An AuditConfig must have one or more AuditLogConfigs. If there are AuditConfigs for both `allServices` and a specific service, the union of the two AuditConfigs is used for that service: the log_types specified in each AuditConfig are enabled, and the exempted_members in each AuditLogConfig are exempted. Example Policy with multiple AuditConfigs: { "audit_configs": [ { "service": "allServices", "audit_log_configs": [ { "log_type": "DATA_READ", "exempted_members": [ "user:jose@example.com" ] }, { "log_type": "DATA_WRITE" }, { "log_type": "ADMIN_READ" } ] }, { "service": "sampleservice.googleapis.com", "audit_log_configs": [ { "log_type": "DATA_READ" }, { "log_type": "DATA_WRITE", "exempted_members": [ "user:aliya@example.com" ] } ] } ] } For sampleservice, this policy enables DATA_READ, DATA_WRITE and ADMIN_READ logging. It also exempts `jose@example.com` from DATA_READ logging, and `aliya@example.com` from DATA_WRITE logging.

Each occurrence of a principal counts towards these limits. For example, if the `bindings` grant 50 different roles to `user:alice@example.com`, and not to any other principal, then you can add another 1,450 principals to the `bindings` in the `Policy`.

You can use a combination of source IP address, virtual machine (VM) instance, or Compute Engine network to uniquely identify the source location. Examples: If the source IP address is an internal IP address within a Google Cloud Virtual Private Cloud (VPC) network, then you must also specify the VPC network. Otherwise, specify the VM instance, which already contains its internal IP address and VPC network information. If the source of the test is within an on-premises network, then you must provide the destination VPC network. If the source endpoint is a Compute Engine VM instance with multiple network interfaces, the instance itself is not sufficient to identify the endpoint. So, you must also specify the source IP address or VPC network. A reachability analysis proceeds even if the source location is ambiguous. However, the test result may include endpoints that you don't intend to test.

patch(name, body=None, updateMask=None, x__xgafv=None)

Updates the configuration of an existing `ConnectivityTest`. After you update a test, the reachability analysis is performed as part of the long running operation, which completes when the analysis completes. The Reachability state in the test resource is updated with the new result. If the endpoint specifications in `ConnectivityTest` are invalid (for example, they contain non-existent resources in the network, or the user does not have read permissions to the network configurations of listed projects), then the reachability result returns a value of UNKNOWN. If the endpoint specifications in `ConnectivityTest` are incomplete, the reachability result returns a value of `AMBIGUOUS`. See the documentation in `ConnectivityTest` for more details.

Args:
  name: string, Identifier. Unique name of the resource using the form: `projects/{project_id}/locations/global/connectivityTests/{test}` (required)
  body: object, The request body.
    The object takes the form of:

  "bypassFirewallChecks": True or False, # Whether the test should skip firewall checking. If not provided, we assume false.
  "createTime": "A String", # Output only. The time the test was created.

  "destination": { # Source or destination of the Connectivity Test. # Required. Destination specification of the Connectivity Test. You can use a combination of destination IP address, Compute Engine VM instance, or VPC network to uniquely identify the destination location. Even if the destination IP address is not unique, the source IP location is unique. Usually, the analysis can infer the destination endpoint from route information. If the destination you specify is a VM instance and the instance has multiple network interfaces, then you must also specify either a destination IP address or VPC network to identify the destination interface. A reachability analysis proceeds even if the destination location is ambiguous. However, the result can include endpoints that you don't intend to test.

Otherwise, specify the VM instance, which already contains its internal IP address and VPC network information. If the source of the test is within an on-premises network, then you must provide the destination VPC network. If the source endpoint is a Compute Engine VM instance with multiple network interfaces, the instance itself is not sufficient to identify the endpoint. So, you must also specify the source IP address or VPC network. A reachability analysis proceeds even if the source location is ambiguous.

Example (Comparison): title: "Summary size limit" description: "Determines if a summary is less than 100 chars" expression: "document.summary.size() < 100" Example (Equality): title: "Requestor is owner" description: "Determines if requestor is the document owner" expression: "document.owner == request.auth.claims.email" Example (Logic): title: "Public documents" description: "Determine whether the document should be publicly visible" expression: "document.type != 'private' && document.type != 'internal'" Example (Data Manipulation): title: "Notification string" description: "Create a notification string with a timestamp." expression: "'New message received at ' + string(document.create_time)" The exact variables and functions that may be referenced within an expression are determined by the service that evaluates it. See the service documentation for additional information. # The condition that is associated with this binding. If the condition evaluates to `true`, then this binding applies to the current request. If the condition evaluates to `false`, then this binding does not apply to the current request. However, a different role binding might grant the same role to one or more of the principals in this binding.

  "etag": "A String", # `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 you to overwrite a version `3` policy with a version `1` policy, and all of the conditions in the version `3` policy are lost.
  "version": 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.
