this definitely works, unfortunately you’re just using the

apply

in the wrong place in your code. To break this down a bit, an Input/Output is a value that isn’t know until after you get the result back from the cloud provider API. Similar to a python List or Dictionary, you have to unpack it before you can use it. In the same way you can’t access a list element without a loop, you can’t use an Input until you’ve resolved the value If you semantically think of

apply

as

resolve_api_call

it starts to make a bit more sense

To use your concrete example:

t = Template(open(f"{getcwd()}/modules/aws_asg/user_data.tpl.sh").read())
templated_user_data = t.substitute({
    'gitlab_runner_token' : gitlab_runner_token.apply(lambda v: f"{v}"),
})

In this situation, you’re opening the

.tpl

template, then you’re trying to resolve the gitlab token value, which is the wrong way round. What you need to do, is reolsve the gitlab token value, then open the template. It ends up looking a bit like this:

gitlab_runner_token.apply(lambda v: Template(open(f"{getcwd()}/modules/aws_asg/user_data.tpl.sh").read()).substitute.....

so in this case, you’re: • resolving the gitlab_runner_token async value • once it’s resolved, it’s now a plain string and can be used as usual in a template

if you’re still struggling, send me the full code you’re using to provision the token and I can get it working for you

Got it to work! Your blog post explained it very well. How would you tackle having multiple Input secrets that need to be templated into one file?

Would that require the

all()

function?

@plain-mechanic-14459 I took some of the feedback and rewrote our inputs/outputs page. WOuld you mind rereading and see if this improves things/helps? http://pulumi-hugo-origin-pr-2996-1599ff0f.s3-website.us-west-2.amazonaws.com/docs/concepts/inputs-outputs/

Was it a temporary deployment? I'm getting a

404 Not Found

I especially like the 'Common pitfalls' section, but maybe you can make it more clear that the code is faulty other than adding

# NOTE: This example is not correct

? Maybe a big red bar in CSS 😄
