Set up GCP SSD disk path in different zone

Question

Pulumi · Accepted Answer

A common requirement when working with cloud resources is creating and attaching a fast SSD disk to a Google Cloud Platform compute instance that may reside in a different zone. The Pulumi resource that represents a Google Cloud SSD disk is `Disk`.

Below is an example of how you may accomplish this with Pulumi:

```typescript
import * as gcp from "@pulumi/gcp";

// Create a GCP compute disk
const disk = new gcp.compute.Disk("myDisk", {
    size: 100,
    type: "pd-ssd", // SSD type disk
    physicalBlockSizeBytes: 4096,
});

// Create a GCP compute instance in a different zone and attach the above disk
const computeInstance = new gcp.compute.Instance("myInstance", {
    machineType: "f1-micro",                                                             // small machine type for example
    bootDisk: { initializeParams: { image: "debian-cloud/debian-9" } },                  // boot from debian image
    networkInterfaces: [{ network: "default", accessConfigs: [{}], subnetwork: "default" }], // assign network settings
    zone: "us-west1-a",                                                                 // the instance is created in the 'us-west1-a' zone
    attachedDisks: [{                                                                  // attach the above SSD disk to this compute instance
        source: disk.selfLink,
        boot: false,
    }],
});

export const instanceName = computeInstance.name;
export const diskName = disk.name;
```

In the disk creation (`new gcp.compute.Disk`), we've chosen a size of 100 GB and SSD type (`pd-ssd`). You may adjust the size and type as needed.

In the instance creation (`new gcp.compute.Instance`), we've chosen a `f1-micro` machine and we're using a default Debian image. These can be replaced with any valid machine type or boot image as needed.

Finally, we attach the previously created disk to the instance using the `attachedDisks` property.

Note that the `zone` property for the instance is set to `'us-west1-a'`. Please ensure you replace it with the zone where you wish to create the instance, and ensure that the disk's region (implicitly set to the project's region) includes this zone.
