The docs for

gcp.compute.AttachedDisk

say:

Note: When using

gcp.compute.AttachedDisk

you must use

lifecycle.ignore_changes = ["attached_disk"]

on the

gcp.compute.Instance

resource that has the disks attached. Otherwise the two resources will fight for control of the attached disk block.

How do I do this? ie, where does this go?

Hey Nick! To use

lifecycle.ignore_changes

with

gcp.compute.AttachedDisk

and

gcp.compute.Instance

, you need to add the

ignoreChanges

option to the instance resource in your Pulumi program. Here's an example in TypeScript:

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

const instance = new gcp.compute.Instance("my-instance", {
    // other instance configuration options...
    attachedDisks: [
        // attached disk configuration...
    ],
}, {
    ignoreChanges: ["attachedDisks"],
});

This will ensure that any changes to the attached disks will not cause Pulumi to try to update the instance resource, avoiding the fight for control of the attached disk block.
