How do I pass an output to the build args of a

Service

? For example, I have

export let apiEndpoint = deployment.invokeUrl.apply(url => url + deployment.stageName);

let nginxService = new cloudAws.Service("nginx", {
    containers: {
        nginx: {
            build: {
                context: "./nginx",
                args: {
                    "API_URL": apiEndpoint,
                    "FRONTEND_URL": frontendUrl
                }
            },
            memory: 256,
            ports: [{port: 443, external: true, protocol: "https"}]
        }
    },
    replicas: 3
});

But it appears build args requires a string, not an

Output

. In the above example,

apiEndpoint

is an output.

Indeed - it looks like this API has not yet been updated to accept

Input<T>

for several inputs. So currently it may not be possible to do this. Opened https://github.com/pulumi/pulumi-cloud/issues/627 to fix this.

Thanks. Is there any way to work around that for now?

There's not a great way to work around it unfortunately. You can technically do something like:

apiEndpoint.apply(endpoint => {
  let nginxService = new cloudAws.Service(...);
});

But creating resources inside an

apply

will lead to a couple potential issues: 1. Previews may not correctly track the creation of the resource. 2. The dependency of the

Service

on the

apiEndpoint

will not be set up correctly. This may mean that the initial deployment might fail, and you would need to retry. The right thing would be to enable this explicitly on the component though.

Hmm ok. I'll experiment with those options to see what will best fit our setup. Yep, direct component support would definitely be best.
