import * as pulumi from "@pulumi/pulumi";
/**
 * Authoritatively manages metadata common to all instances for a project in GCE. For more information see
 * [the official documentation](https://cloud.google.com/compute/docs/storing-retrieving-metadata)
 * and
 * [API](https://cloud.google.com/compute/docs/reference/latest/projects/setCommonInstanceMetadata).
 *
 * > **Note:**  This resource manages all project-level metadata including project-level ssh keys.
 * Keys unset in config but set on the server will be removed. If you want to manage only single
 * key/value pairs within the project metadata rather than the entire set, then use
 * google_compute_project_metadata_item.
 *
 * ## Example Usage
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as gcp from "@pulumi/gcp";
 *
 * const _default = new gcp.compute.ProjectMetadata("default", {metadata: {
 *     foo: "bar",
 *     fizz: "buzz",
 *     "13": "42",
 * }});
 * ```
 *
 * ### Adding An SSH Key
 *
 * ```typescript
 * import * as pulumi from "@pulumi/pulumi";
 * import * as gcp from "@pulumi/gcp";
 *
 * //A key set in project metadata is propagated to every instance in the project.
 * //This resource configuration is prone to causing frequent diffs as Google adds SSH Keys when the SSH Button is pressed in the console.
 * //It is better to use OS Login instead.
 * const mySshKey = new gcp.compute.ProjectMetadata("my_ssh_key", {metadata: {
 *     "ssh-keys": `      dev:ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILg6UtHDNyMNAh0GjaytsJdrUxjtLy3APXqZfNZhvCeT dev
 *       foo:ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAILg6UtHDNyMNAh0GjaytsJdrUxjtLy3APXqZfNZhvCeT bar
 * `,
 * }});
 * ```
 *
 * ## Import
 *
 * Project metadata can be imported using the project ID:
 *
 * * `{{project_id}}`
 *
 * When using the `pulumi import` command, project metadata can be imported using one of the formats above. For example:
 *
 * ```sh
 * $ pulumi import gcp:compute/projectMetadata:ProjectMetadata default {{project_id}}
 * ```
