Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the Regions Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.

#get(request, options = nil) ⇒ ::Google::Cloud::Compute::V1::Region #get(project: nil, region: nil) ⇒ ::Google::Cloud::Compute::V1::Region

Returns the specified Region resource. To decrease latency for this method, you can optionally omit any unneeded information from the response by using a field mask. This practice is especially recommended for unused quota information (the quotas field). To exclude one or more fields, set your request's fields query parameter to only include the fields you need. For example, to only include the id and selfLink fields, add the query parameter ?fields=id,selfLink to your request. This method fails if the quota information is unavailable for the region and if the organization policy constraint compute.requireBasicQuotaInResponse is enforced. This constraint, when enforced, disables the fail-open behaviour when quota information (the items.quotas field) is unavailable for the region. It is recommended to use the default setting for the constraint unless your application requires the fail-closed behaviour for this method.

Examples:

Basic example

require "google/cloud/compute/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Compute::V1::Regions::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Compute::V1::GetRegionRequest.new

# Call the get method.
result = client.get request

# The returned object is of type Google::Cloud::Compute::V1::Region.
p result

Overloads:

  • #get(request, options = nil) ⇒ ::Google::Cloud::Compute::V1::Region

    Pass arguments to get via a request object, either of type GetRegionRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Compute::V1::GetRegionRequest, ::Hash) —

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries etc. Optional.

  • #get(project: nil, region: nil) ⇒ ::Google::Cloud::Compute::V1::Region

    Pass arguments to get via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • project (::String) (defaults to: nil) —

      Project ID for this request.

    • region (::String) (defaults to: nil) —

      Name of the region resource to return.

Yields:

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.

Retrieves the list of region resources available to the specified project. To decrease latency for this method, you can optionally omit any unneeded information from the response by using a field mask. This practice is especially recommended for unused quota information (the items.quotas field). To exclude one or more fields, set your request's fields query parameter to only include the fields you need. For example, to only include the id and selfLink fields, add the query parameter ?fields=id,selfLink to your request. This method fails if the quota information is unavailable for the region and if the organization policy constraint compute.requireBasicQuotaInResponse is enforced. This constraint, when enforced, disables the fail-open behaviour when quota information (the items.quotas field) is unavailable for the region. It is recommended to use the default setting for the constraint unless your application requires the fail-closed behaviour for this method.

Examples:

Basic example

require "google/cloud/compute/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Compute::V1::Regions::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Compute::V1::ListRegionsRequest.new

# Call the list method.
result = client.list request

# The returned object is of type Google::Cloud::Compute::V1::RegionList.
p result

Overloads:

  • #list(request, options = nil) ⇒ ::Gapic::Rest::PagedEnumerable<::Google::Cloud::Compute::V1::Region>

    Pass arguments to list via a request object, either of type ListRegionsRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::Compute::V1::ListRegionsRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries etc. Optional.

  • #list(filter: nil, max_results: nil, order_by: nil, page_token: nil, project: nil, return_partial_success: nil) ⇒ ::Gapic::Rest::PagedEnumerable<::Google::Cloud::Compute::V1::Region>

    Pass arguments to list via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • filter (::String) (defaults to: nil) —

      A filter expression that filters resources listed in the response. Most Compute resources support two types of filter expressions: expressions that support regular expressions and expressions that follow API improvement proposal AIP-160. These two types of filter expressions cannot be mixed in one request. If you want to use AIP-160, your expression must specify the field name, an operator, and the value that you want to use for filtering. The value must be a string, a number, or a boolean. The operator must be either =, !=, >, <, <=, >= or :. For example, if you are filtering Compute Engine instances, you can exclude instances named example-instance by specifying name != example-instance. The :* comparison can be used to test whether a key has been defined. For example, to find all objects with owner label use: labels.owner:* You can also filter nested fields. For example, you could specify scheduling.automaticRestart = false to include instances only if they are not scheduled for automatic restarts. You can use filtering on nested fields to filter based on resource labels. To filter on multiple expressions, provide each separate expression within parentheses. For example: (scheduling.automaticRestart = true) (cpuPlatform = "Intel Skylake") By default, each expression is an AND expression. However, you can include AND and OR expressions explicitly. For example: (cpuPlatform = "Intel Skylake") OR (cpuPlatform = "Intel Broadwell") AND (scheduling.automaticRestart = true) If you want to use a regular expression, use the eq (equal) or ne (not equal) operator against a single un-parenthesized expression with or without quotes or against multiple parenthesized expressions. Examples: fieldname eq unquoted literal fieldname eq 'single quoted literal' fieldname eq "double quoted literal" (fieldname1 eq literal) (fieldname2 ne "literal") The literal value is interpreted as a regular expression using Google RE2 library syntax. The literal value must match the entire field. For example, to filter for instances that do not end with name "instance", you would use name ne .*instance. You cannot combine constraints on multiple fields using regular expressions.

    • max_results (::Integer) (defaults to: nil) —

      The maximum number of results per page that should be returned. If the number of available results is larger than maxResults, Compute Engine returns a nextPageToken that can be used to get the next page of results in subsequent list requests. Acceptable values are 0 to 500, inclusive. (Default: 500)

    • order_by (::String) (defaults to: nil) —

      Sorts list results by a certain order. By default, results are returned in alphanumerical order based on the resource name. You can also sort results in descending order based on the creation timestamp using orderBy="creationTimestamp desc". This sorts results based on the creationTimestamp field in reverse chronological order (newest result first). Use this to sort resources like operations so that the newest operation is returned first. Currently, only sorting by name or creationTimestamp desc is supported.

    • page_token (::String) (defaults to: nil) —

      Specifies a page token to use. Set pageToken to the nextPageToken returned by a previous list request to get the next page of results.

    • project (::String) (defaults to: nil) —

      Project ID for this request.

    • return_partial_success (::Boolean) (defaults to: nil) —

      Opt-in for partial success behavior which provides partial results in case of failure. The default value is false. For example, when partial success behavior is enabled, aggregatedList for a single zone scope either returns all resources in the zone or no resources, with an error code.

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.
