Question

Hi can anyone explain to me how does `pulumi ResourceOptions providers= mapping ` work I looked at the type description but it s not helpful and nor is the docstring Because when the resource is created like this ```opts = pulumi ResourceOptions parent=self provider=classic aws provider ``` and later on `opts` is modified to use `providers` parameter ```opts pulumi ResourceOptions parent=self providers= aws classic aws provider aws native aws native provider ``` Pulumi results in creating `default` aws provider and completely ignore `providers`

let me check my projects I think I ve got one where I needed to use 2 providers

prehistoric-activity-61023 · Answer

ok I see that `providers` is of type ```Optional Union Mapping str ProviderResource List ProviderResource ```

prehistoric-activity-61023 · Answer

and I actually used a list every provider is a different type so you don t need to name them

prehistoric-activity-61023 · Answer

but I think your approach should work as well

prehistoric-activity-61023 · Answer

can you try to pass these providers as list and see if that helps ``` providers= classic aws provider aws native provider ```

prehistoric-activity-61023 · Answer

keep in mind that resources inherit their parent providers so in most cases you don t need to explicitly specify providers in child resources or within ComponentResource classes where you usually assign `self` as a parent

prehistoric-activity-61023 · Answer

btw there s also a note saying ```Note do not provide both provider and providers ```

prehistoric-activity-61023 · Answer

If the tip above doesn t work could you explain what you meant by gt and later on `opts` is modified to use `providers` parameter I m afraid you might somehow set both parameters and that s the root cause of this

P S `you don t need to explicitly specify providers` this lead to many problems that created a silent default provider for whatever reason and that s what I want to avoid I also tried the `list` and it did not go well Because pulumi silently used a `default` provider This is what I m trying to achieve but I may be misunderstanding something ``` self opts = pulumi ResourceOptions merge opts pulumi ResourceOptions parent=self providers= aws classic provider aws native provider classic role = aws classic iam Role f self config name classic role args=aws classic iam RoleArgs assume role policy=json dumps assume policy tags=self config tags opts=self opts here I expect Pulumi to pick my classic provider native role = aws native iam Role f self config name native role args=aws native iam RoleArgs assume role policy document=assume policy opts=self opts here I expect my native provider ``` but the code below ends with ```pulumi providers aws native default 4 32 0 1 error pulumi providers aws native default 4 32 0 error no resource plugin aws native v4 32 0 found in the workspace or on your $PATH install the plugin using `pulumi plugin install resource aws native v4 32 0```` It looks like something is confused by the mapping

Regarding the default provider in my project I stopped using default provider configuration completely Everything except ResourceComponents that rely on parent providers receives explicit providers

prehistoric-activity-61023 · Answer

If I find some time I ll try to repro it locally on my side My current guess is that you defined both `provider` and `providers` Can you add a simple print debugging statement and check how this `self opts` actually looks like Plus can you confirm that these resources are created within ComponentResource definition this is what I assumed based on `parent=self` If so how are you creating this resource Do you specify any `opts` in the constructor

gt Regarding the default provider Yes me too that s why I inspect the state to make sure that the default provider is not created somehow gt that you defined both provider and providers No only `providers` gt heck how this self opts actually looks like ComponentResource definition this yes it is a ComponentResource and I do not pass `provider` to the constructor nor `providers` When my ComponentResources need provider I ask for that explicitly rather than assuming it from `opts`

thinking face

prehistoric-activity-61023 · Answer

the other difference I see is that you used `pulumi ResourceOptions merge`

prehistoric-activity-61023 · Answer

maybe it s related to that

great-sunset-355 · Answer

I doubt that Here is what I got with the `print` ``` merge lt bound method ResourceOptions merge instance of lt pulumi resource ResourceOptions object at 0x7f42bfb39910 gt gt parent lt tqs infrastructure components native fargate FargateApp object at 0x7f42bfb39370 gt protect None provider None providers aws lt pulumi aws provider Provider object at 0x7f42bfbd2d90 gt aws native lt pulumi aws native provider Provider object at 0x7f42bfb64370 gt delete before replace None ignore changes None version None aliases None additional secret outputs None custom timeouts None id None import None transformations None urn None replace on changes None depends on ``` to me this looks as expected though the result is unexpected
