/**
 * Represents an Autoscaler resource.
 *
 * Autoscalers allow you to automatically scale virtual machine instances in
 * managed instance groups according to an autoscaling policy that you
 * define.
 *
 * To get more information about Autoscaler, see:
 *
 * * [API documentation](https://cloud.google.com/compute/docs/reference/rest/v1/autoscalers)
 * * How-to Guides
 *     * [Autoscaling Groups of Instances](https://cloud.google.com/compute/docs/autoscaler/)
 *
 * ## Example Usage
 *
 * ### Autoscaler Single Instance
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as gcp from "@pulumi/gcp";
 *
 * const debian9 = gcp.compute.getImage({
 *     family: "debian-11",
 *     project: "debian-cloud",
 * });
 * const defaultInstanceTemplate = new gcp.compute.InstanceTemplate("default", {
 *     name: "my-instance-template",
 *     machineType: "e2-medium",
 *     canIpForward: false,
 *     tags: [
 *         "foo",
 *         "bar",
 *     ],
 *     disks: [{
 *         sourceImage: debian9.then(debian9 => debian9.id),
 *     }],
 *     networkInterfaces: [{
 *         network: "default",
 *     }],
 *     metadata: {
 *         foo: "bar",
 *     },
 *     serviceAccount: {
 *         scopes: [
 *             "userinfo-email",
 *             "compute-ro",
 *             "storage-ro",
 *         ],
 *     },
 * });
 * const defaultTargetPool = new gcp.compute.TargetPool("default", {name: "my-target-pool"});
 * const defaultInstanceGroupManager = new gcp.compute.InstanceGroupManager("default", {
 *     name: "my-igm",
 *     zone: "us-central1-f",
 *     versions: [{
 *         instanceTemplate: defaultInstanceTemplate.id,
 *         name: "primary",
 *     }],
 *     targetPools: [defaultTargetPool.id],
 *     baseInstanceName: "autoscaler-sample",
 * });
 * const _default = new gcp.compute.Autoscaler("default", {
 *     name: "my-autoscaler",
 *     zone: "us-central1-f",
 *     target: defaultInstanceGroupManager.id,
 *     autoscalingPolicy: {
 *         maxReplicas: 5,
 *         minReplicas: 1,
 *         cooldownPeriod: 60,
 *         metrics: [{
 *             name: "pubsub.googleapis.com/subscription/num_undelivered_messages",
 *             filter: "resource.type = pubsub_subscription AND resource.label.subscription_id = our-subscription",
 *             singleInstanceAssignment: 65535,
 *         }],
 *     },
 * });
 * ```
 * ### Autoscaler Basic
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as gcp from "@pulumi/gcp";
 *
 * const debian9 = gcp.compute.getImage({
 *     family: "debian-11",
 *     project: "debian-cloud",
 * });
 * const foobarInstanceTemplate = new gcp.compute.InstanceTemplate("foobar", {
 *     name: "my-instance-template",
 *     machineType: "e2-medium",
 *     canIpForward: false,
 *     tags: [
 *         "foo",
 *         "bar",
 *     ],
 *     disks: [{
 *         sourceImage: debian9.then(debian9 => debian9.id),
 *     }],
 *     networkInterfaces: [{
 *         network: "default",
 *     }],
 *     metadata: {
 *         foo: "bar",
 *     },
 *     serviceAccount: {
 *         scopes: [
 *             "userinfo-email",
 *             "compute-ro",
 *             "storage-ro",
 *         ],
 *     },
 * });
 * const foobarTargetPool = new gcp.compute.TargetPool("foobar", {name: "my-target-pool"});
 * const foobarInstanceGroupManager = new gcp.compute.InstanceGroupManager("foobar", {
 *     name: "my-igm",
 *     zone: "us-central1-f",
 *     versions: [{
 *         instanceTemplate: foobarInstanceTemplate.id,
 *         name: "primary",
 *     }],
 *     targetPools: [foobarTargetPool.id],
 *     baseInstanceName: "foobar",
 * });
 * const foobar = new gcp.compute.Autoscaler("foobar", {
 *     name: "my-autoscaler",
 *     zone: "us-central1-f",
 *     target: foobarInstanceGroupManager.id,
 *     autoscalingPolicy: {
 *         maxReplicas: 5,
 *         minReplicas: 1,
 *         cooldownPeriod: 60,
 *         cpuUtilization: {
 *             target: 0.5,
 *         },
 *     },
 * });
 * ```
 *
 * ## Import
 *
 * Autoscaler can be imported using any of these accepted formats:
 *
 * * `projects/{{project}}/zones/{{zone}}/autoscalers/{{name}}`
 *
 * * `{{project}}/{{zone}}/{{name}}`
 *
 * * `{{zone}}/{{name}}`
 *
 * * `{{name}}`
 *
 * When using the `pulumi import` command, Autoscaler can be imported using one of the formats above. For example:
 *
 * ```sh
 * $ pulumi import gcp:compute/autoscaler:Autoscaler default projects/{{project}}/zones/{{zone}}/autoscalers/{{name}}
 * ```
 *
 * ```sh
 * $ pulumi import gcp:compute/autoscaler:Autoscaler default {{project}}/{{zone}}/{{name}}
 * ```
 *
 * ```sh
 * $ pulumi import gcp:compute/autoscaler:Autoscaler default {{zone}}/{{name}}
 * ```
 *
 * ```sh
 * $ pulumi import gcp:compute/autoscaler:Autoscaler default {{name}}
 * ```
