Cannot use 'dataBaseServer.ID()' (type IDOutput) as the type IntInputType

[ayumakesit]

What happened?

Following the example to create a firewall I’m trying to use the ID of the created droplet. The example: https://www.pulumi.com/registry/packages/digitalocean/api-docs/firewall/

I get the following error:

Cannot use 'dataBaseServer.ID()' (type IDOutput) as the type IntInputType does not implement 'IntInput' as some methods are missing:ToIntOutput() IntOutputToIntOutputWithContext(ctx context.Context) IntOutputToIntPtrOutput() IntPtrOutput…

Example

dataBaseServer, err := do.NewDroplet(ctx, name, &do.DropletArgs{
    Size:    pulumi.String("s-1vcpu-2gb"),
    Image:   pulumi.String("ubuntu-22-04-x64"),
    Region:  pulumi.String(region),
    VpcUuid: vpc.ID(),
})

if err != nil {
    return err
}

_, err = do.NewFirewall(ctx, "databaseFirewall", &do.FirewallArgs{
    DropletIds: pulumi.IntArray{
        dataBaseServer.ID(),
    },
    InboundRules: do.FirewallInboundRuleArray{},
    OutboundRules: do.FirewallOutboundRuleArray{},
})

Hi @ayumakesit

This is because resource IDs are strings in Pulumi, while DropletIds expects integers. Assuming dataBaseServer.ID() is in fact an integer, you should be able to convert it with something like

_, err = do.NewFirewall(ctx, "databaseFirewall", &do.FirewallArgs{
    DropletIds: pulumi.IntArray{
        dataBaseServer.ID().ToStringOutput().ApplyT(func(id string) int {
            v, _ := strconv.Atoi(id)
            return v
        }).(pulumi.IntOutput),
    },
    InboundRules: do.FirewallInboundRuleArray{},
    OutboundRules: do.FirewallOutboundRuleArray{},
})

A similar issue for TypeScript: https://github.com/pulumi/pulumi-digitalocean/issues/81

Let me know if this helps.

Hi @mikhailshilkov, thank you for the response :)

I already converted it:

_, err = do.NewFirewall(ctx, "databaseFirewall", &do.FirewallArgs{
    DropletIds: pulumi.IntArray{
        dataBaseServer.ID().ApplyT(strconv.Atoi).(pulumi.IntOutput),
    },
    InboundRules: do.FirewallInboundRuleArray{
        &do.FirewallInboundRuleArgs{
            Protocol:  pulumi.String("tcp"),
            PortRange: pulumi.String("22"),
        },
    },
    OutboundRules: do.FirewallOutboundRuleArray{},
})

For newbies like me, it would be very helpful if the documentation could show the right way ;)

Great to hear you are unblocked! I'll leave the issue open to track fixing the example.
