A list of all the future reservations that have been configured for the specified project in specified zone.

HTTP request

GET https://compute.googleapis.com/compute/beta/projects/{project}/zones/{zone}/futureReservations

The URL uses gRPC Transcoding syntax.

Path parameters

Parameters

Parameters
`project`	`string` Project ID for this request.
`zone`	`string` Name of the zone for this request. Name should conform to RFC1035.

project

string

Project ID for this request.

zone

string

Name of the zone for this request. Name should conform to RFC1035.

Query parameters

Parameters
`maxResults`	`integer (uint32 format)` 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`)
`pageToken`	`string` Specifies a page token to use. Set `pageToken` to the `nextPageToken` returned by a previous list request to get the next page of results.
`filter`	`string` 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.
`orderBy`	`string` 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.
`returnPartialSuccess`	`boolean` 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.

Duration time unit is represented as a count of seconds and fractions of seconds at nanosecond resolution.
`items[].autoCreatedReservationsDuration.seconds`	`string (int64 format)` Span of time at a resolution of a second. Must be from 0 to 315,576,000,000 inclusive. Note: these bounds are computed from: 60 sec/min * 60 min/hr * 24 hr/day * 365.25 days/year * 10000 years
`items[].autoCreatedReservationsDuration.nanos`	`integer` Span of time that's a fraction of a second at nanosecond resolution. Durations less than one second are represented with a 0 `seconds` field and a positive `nanos` field. Must be from 0 to 999,999,999 inclusive.
`items[].autoDeleteAutoCreatedReservations`	`boolean` Setting for enabling or disabling automatic deletion for auto-created reservation. If set to true, auto-created reservations will be deleted at Future Reservation's end time (default) or at user's defined timestamp if any of the [autoCreatedReservationsDeleteTime, autoCreatedReservationsDuration] values is specified. For keeping auto-created reservation indefinitely, this value should be set to false.
`items[].specificReservationRequired`	`boolean` Indicates whether the auto-created reservation can be consumed by VMs with affinity for "any" reservation. If the field is set, then only VMs that target the reservation by name can consume from the delivered reservation.
`items[].reservationName`	`string` Name of reservations where the capacity is provisioned at the time of delivery of future reservations. If the reservation with the given name does not exist already, it is created automatically at the time of Approval with INACTIVE state till specified start-time. Either provide the reservationName or a namePrefix.
`items[].deploymentType`	`enum` Type of the deployment requested as part of future reservation.
`items[].instanceTerminationAction`	`enum` Action to take during reservation termination.
`items[].enableOpportunisticMaintenance`	`boolean` Indicates if this group of VMs have opportunistic maintenance enabled. This will be set on the FR by customers, and will be used for reservation and reservation block maintenance .
`items[].schedulingType`	`enum` Maintenance information for this reservation
`nextPageToken`	`string` [Output Only] This token allows you to get the next page of results for list requests. If the number of results is larger than `maxResults`, use the `nextPageToken` as a value for the query parameter `pageToken` in the next list request. Subsequent list requests will have their own `nextPageToken` to continue paging through the results.
`warning`	`object` [Output Only] Informational warning message.
`warning.code`	`enum` [Output Only] A warning code, if applicable. For example, Compute Engine returns `NO_RESULTS_ON_PAGE` if there are no results in the response.
`warning.message`	`string` [Output Only] A human-readable description of the warning code.
`warning.data[]`	`object` [Output Only] Metadata about this warning in `key: value` format. For example: "data": [ { "key": "scope", "value": "zones/us-east1-d" }
`warning.data[].key`	`string` [Output Only] A key that provides more detail on the warning being returned. For example, for warnings where there are no results in a list request for a particular zone, this key might be `scope` and the key value might be the zone name. Other examples might be a key indicating a deprecated resource and a suggested replacement, or a warning about invalid network settings (for example, if an instance attempts to perform IP forwarding but is not enabled for IP forwarding).
`warning.data[].value`	`string` [Output Only] A warning data value corresponding to the key.
`selfLink`	`string` [Output Only] Server-defined URL for this resource.
`etag`	`string`
`unreachables[]`	`string` [Output Only] Unreachable resources.
