Hi, can anyone direct me on how to modify an pulumi output obj - AWS? I have created an RouteTable object with one route. Now I want to modify this object by adding another route to the table. I have the created the object (rt) and now I tried to append to routes by

rt.routes.append(<new route args>)

but I’m getting the followiing error

route_table.routes.append(route_args)
TypeError: 'Output' object is not callable

The

routes

property is an "output" property of RouteTable, which means it's read-only. To add routes to a route table, you can either declare them on the

RouteTable

declaration itself, like this: https://github.com/pulumi/examples/blob/45eeabec900da9f8d2446d36879887828560f086/aws-py-eks/vpc.py#L24C1-L34C2 or as individual

Route

resources associated to the

RouteTable

, such as https://github.com/pulumi/examples/blob/45eeabec900da9f8d2446d36879887828560f086/aws-py-hub-and-spoke-network/inspection.py#L303-L314

I think it’s closer to the second example, but is the key the ResourceOptions?

Are the new route entry and peering connection being managed by the same Pulumi program that defines the RouteTables?

yes

So you're adding new code to, say, the same Python file that defines the RouteTables, ok. I haven't tried this myself (not super familiar with these resources) , but I suspect you'll want to do something like this -- this is TypeScript, but the resources are the same, with additional

Route

resources declared that reference a `VpcPeeringConnection`: https://github.com/pulumi/examples/blob/45eeabec900da9f8d2446d36879887828560f086/aws-ts-stackreference-architecture/networking/src/vpc.ts#L311-L335

Thank you I’ll take a look

You bet, let me know if it helps! There's a bunch of code in there, but I think those are the resources and relationships you're looking for

I got it working thanks for the tips/samples
