Unexpected diff with reserved ips

[kumavis]

Describe what happened

"floatingip" was renamed "reservedip" at digitalocean. see the note at the top of this blog post

somewhere the old name is being used and shows up as an anomalous diff

      ~ resources: [
          ~ [1]: "do:floatingip:164.90.244.175" => "do:reservedip:164.90.244.175"
        ]

Sample program

const sshKey = digitalocean.getSshKeyOutput({
  name: sshKeyName,
});

const droplet = new digitalocean.Droplet('primary', {
  image: 'ubuntu-20-04-x64',
  name: 'test-droplet',
  region,
  size: digitalocean.DropletSlug.DropletS1VCPU1GB,
  sshKeys: [sshKey.fingerprint],
  monitoring: true,
  dropletAgent: false,
  userData: makeBashScript(
    sshSecurityEnhancements,
    installDocker,
  ),
});

const reservedIp = new digitalocean.ReservedIp(`primary`, {
  region,
});

new digitalocean.ReservedIpAssignment(`primary`, {
  ipAddress: reservedIp.ipAddress,
  dropletId: fixForDoId(droplet.id),
});

const project = new digitalocean.Project('primary', {
  name: 'playground2',
  description: 'A project to represent development resources.',
  // purpose: 'Web Application',
  // environment: 'Development',
  resources: [
    droplet.dropletUrn,
    reservedIp.reservedIpUrn,
  ],
});

@kumavis thanks for your ticket and sorry you had issues. Given the resource was renamed it seems expected that the URN of the resource has changed too.

What is anomalous about the diff?

What is anomalous about the diff?

"floatingip" was renamed to "reservedip" internally at digitalocean, but refers to the same feature.

(do:floatingip:..., do:reservedip:...) refer to the exact same instance of a reserved ip on digitalocean. this rename needs to be handled somewhere in pulumi

     ~ [1]: "do:floatingip:164.90.244.175" => "do:reservedip:164.90.244.175"

@kumavis if you change the resource type for a resource that you have already created (i.e. new digitalocean.FloatingIp => new digitalocean.ReservedIp) then it will cause a diff. You can tell Pulumi to treat the two resources as the same thing by using Aliases

I think this should work for your case.

const reservedIp = new digitalocean.ReservedIp(`primary`, {
  region,
}, {
  aliases: [ { type: 'do:floatingip' } ],
});

i have not done this. i have not made any change. this diff is appear despite not making any change, thus "anomalous" diff.

thanks ill take a look

@kumavis ah ok I misunderstood the issue. It looks like this is an issue with the upstream provider not yet supporting reserved ip in the Project resource.

You could try the workaround they suggest or you could use the FloatingIp resource since it is still available.
