Is the idiomatic thing to do for unmet pre-conditions in a ComponentResource’s inputs to throw an exception?

An AMI locator might be a nice abstraction for the Typescript SDK. Basically a priority selection between: - a specific AMI ID - an AMI name/owner pair + maybe additional filters - some default fallback (potentially)

It’s a pattern I’ve had to use 2-3 times over the last day or two

Also, is there a way to do a “targeted update”?

Another one; has anyone done an initial run of newly created lambda function from the pulumi program that created it?

Is there a way to arrange a component such that all resources it creates must be created before it is considered fully created, such that using the component in

dependsOn

works across other components?

I'm trying to create a policy for SSM and need the accountId for the urn, but I can't seem to figure out a way to get it using the js lib. I see aws.getCallerIdentity, but that returns a promise. Any hints?

stocky-spoon-28903

08/08/2018, 11:05 PM

@bland-lamp-97030 You can await the result of the promise

bland-lamp-97030

outside of a function?

stocky-spoon-28903

08/08/2018, 11:06 PM

Not outside, no. Are you in the global scope at the moment?

bland-lamp-97030

08/08/2018, 11:07 PM

yes, just creating resources in index.js

One pattern I’ve used (as recommended by various people here) is an “async main” function, like this: https://gist.github.com/jen20/ccc91ab961843babf93b119fe67e1938

(Note that that particular gist is reproducing a crash though, so probably not the best one to copy/paste - the pattern is there though)

Do you just need to pass the account ID into the input of another resource?

bland-lamp-97030

08/08/2018, 11:09 PM

right, thanks, that makes sense!

I’m guessing for a policy it needs to go into a stringified object

bland-lamp-97030

Resource: aws.getCallerIdentity().then(resp => arn:aws:ssm:${region}:${resp.accountId}:parameter/myapp*)

bland-lamp-97030

08/08/2018, 11:10 PM

basically that

within a policy json stringify

microscopic-florist-22719

08/08/2018, 11:10 PM

Got it. Can you DM me the full stringify?

microscopic-florist-22719

08/08/2018, 11:10 PM

(assuming that you don't want to post it here)

bland-lamp-97030

08/08/2018, 11:11 PM

no, I don't mind, but I think the async func will work for my purposes

const policy = new aws.iam.RolePolicy("ksub-application-role-policy", {
  role: role.name,

    Statement: [
      {
        Action: ["ssm:GetParameters"],
        Effect: "Allow",
        Resource: aws.getCallerIdentity().then(resp => `arn:aws:ssm:${region}:${resp.accountId}:parameter/KSUB_*`), // how??
      },

Here’s a good example of using a promise value in a policy btw: https://github.com/jen20/lambda-cert/blob/master/pulumi/src/index.ts#L190-L253

bland-lamp-97030

08/08/2018, 11:11 PM

I didn't think the promise.then would work, but I found it in an example and figured I'd try it out

bland-lamp-97030

08/08/2018, 11:12 PM

I should just stick to the python libs 🙂

The canonical way to achieve what you need is to lift the `.then`:

const policy = new aws.iam.RolePolicy("ksub-application-role-policy", {
  role: role.name,
  policy: aws.getCallerIdentity().then(resp => JSON.stringify({
    Version: "2012-10-17",
    Statement: [
      {
        Action: ["ssm:GetParameters"],
        Effect: "Allow",
        Resource:  `arn:aws:ssm:${region}:${resp.accountId}:parameter/KSUB_*`,
      },
      {
        Action: ["kms:Decrypt"],
        Effect: "Allow",
        Resource: kmsKey.arn,
      },
      {
        Action: [
          "autoscaling:Describe*",
          "ec2:Describe*",
          "ec2:Get*",
          "ecs:Describe*",
          "ecs:List*",
          "elasticache:Describe*",
          "elasticache:List*",
          "elasticloadbalancing:Describe*",
          "iam:Get*",
          "iam:List*",
          "ssm:DescribeParameters",
          "rds:Describe*",
          "rds:List*",
        ],
        Effect: "Allow",
        Resource: "*",
      },
    ],
  })),
});

That’s quite a lot nicer.

bland-lamp-97030

08/08/2018, 11:13 PM

oh, of course 👍

stocky-spoon-28903

The other important thing to know about there is

pulumi.all

for if you need to depend on multiple promised parameters
