hi, I'm all new to

pulumi

and I have a question about javascript usage:

Copy code

// 1.
const image = new docker.Image(...) // promise ?

// 2.
const service = new gcp.cloudrun.Service(, { // promise too
  ...
  image: image.imageName,
  ...
})

I guess 1.

new docker.Image

returns a promise, but how 2.

await

for it ?

it’s not really a promise, it’s an

Output

which is promise like Why do you want to await it?

no I'm just trying to figure out the flow of instructions

you should just be able to pass image.name through to the service args, as inputs/outputs are interchangeable as far as i understand it

I guess this is the answer to my "flow" question:

Pulumi automatically captures dependencies when you pass an output from one resource as an input to another resource.

I'm sure there are reasons for this, but I would have really preferred avoiding this type of magic, and handle this with classical promises/await

@ripe-cat-40820 the reason for this is that primises are not a thing in our other supported languages

billowy-army-68599

and we support more languages than javascript

a lot of the semantics are the same, but it’s declarative
