/**
 * Represents the Instance membership to the Instance Group.
 *
 * > **NOTE** You can use this resource instead of the `instances` field in the
 * `gcp.compute.InstanceGroup`, however it's not recommended to use it alongside this field.
 * It might cause inconsistencies, as they can end up competing over control.
 *
 * > **NOTE** This resource has been added to avoid a situation, where after
 * Instance is recreated, it's removed from Instance Group and it's needed to
 * perform `apply` twice. To avoid situations like this, please use this resource
 * with the lifecycle `replaceTriggeredBy` method, with the passed Instance's ID.
 *
 * To get more information about InstanceGroupMembership, see:
 *
 * * [API documentation](https://cloud.google.com/compute/docs/reference/rest/v1/instanceGroups)
 * * How-to Guides
 *     * [Add instances](https://cloud.google.com/compute/docs/reference/rest/v1/instanceGroups/addInstances)
 *     * [List instances](https://cloud.google.com/compute/docs/reference/rest/v1/instanceGroups/listInstances)

 *
 * ## Example Usage
 *
 * ### Instance Group Membership
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as gcp from "@pulumi/gcp";
 *
 * const default_network = new gcp.compute.Network("default-network", {name: "network"});
 * const default_instance = new gcp.compute.Instance("default-instance", {
 *     name: "instance",
 *     machineType: "e2-medium",
 *     bootDisk: {
 *         initializeParams: {
 *             image: "debian-cloud/debian-11",
 *         },
 *     },
 *     networkInterfaces: [{
 *         network: default_network.name,
 *     }],
 * });
 * const default_instance_group = new gcp.compute.InstanceGroup("default-instance-group", {name: "instance-group"});
 * const default_ig_membership = new gcp.compute.InstanceGroupMembership("default-ig-membership", {
 *     instance: default_instance.selfLink,
 *     instanceGroup: default_instance_group.name,
 * });
 * ```
 *
 * ## Import
 *
 * InstanceGroupMembership can be imported using any of these accepted formats:
 *
 * * `projects/{{project}}/zones/{{zone}}/instanceGroups/{{instance_group}}/{{instance}}`
 *
 * * `{{project}}/{{zone}}/{{instance_group}}/{{instance}}`
 *
 * * `{{zone}}/{{instance_group}}/{{instance}}`
 *
 * * `{{instance_group}}/{{instance}}`
 *
 * When using the `pulumi import` command, InstanceGroupMembership can be imported using one of the formats above. For example:
 *
 * ```sh
 * $ pulumi import gcp:compute/instanceGroupMembership:InstanceGroupMembership default projects/{{project}}/zones/{{zone}}/instanceGroups/{{instance_group}}/{{instance}}
 * ```
 *
 * ```sh
 * $ pulumi import gcp:compute/instanceGroupMembership:InstanceGroupMembership default {{project}}/{{zone}}/{{instance_group}}/{{instance}}
 * ```
 *
 * ```sh
 * $ pulumi import gcp:compute/instanceGroupMembership:InstanceGroupMembership default {{zone}}/{{instance_group}}/{{instance}}
 * ```
 *
 * ```sh
 * $ pulumi import gcp:compute/instanceGroupMembership:InstanceGroupMembership default {{instance_group}}/{{instance}}
 * ```
