if one of these happen - pulumi will attempt to reconfigure resource to desired state

@straight-napkin-70642 can you elaborate on what you're trying to achieve? By default, a

pulumi up

does not do a refresh from your cloud. That's what

--refresh

or

pulumi refresh

is for.

Pulumi does support dependencies... they're usually implicit by references between resources using outputs.

For example, this line https://github.com/pulumi/examples/blob/master/aws-py-webserver/__main__.py#L23 creates a dependency on the security group defined further up in the application.

@gentle-diamond-70147 you can do pulumi up --refresh?

and it would do a refresh + up? or force up or what?

yes, you can do

pulumi up --refresh

. It essentially does the same as

pulumi refresh

and then

pulumi up

when run separately. It does the refresh and then diff against the updated state and still prompts you before continuing.

ok, thats useful, i suppose. as I was using refresh followed by up, thanks!

Anyone have experience writing python tests for pulumi? Read @big-piano-35669’s blog post and trying to kick the tires on this. https://blog.pulumi.com/testing-your-infrastructure-as-code-with-pulumi Is there an example of the tests from that blog but written in Python?

Another experience request: has anyone experience integrating pulumi and AWS chalice ( chalice.readthedocs.io ) ? Particularly I would love to develop with chalice and deploy with pulumi but proxy integration doesn't look to work with chalice, and I don't want to manually sync methods between chalice and pulumi.

Hi there, just getting started on pulumi (awesome software btw) , I'm having troubles retrieving AZs with pulumi_aws, I think i may be doing something wrong, just want to double check with you. I'm creating a ComponentResource and getting the AZs but asyncio is complaining it can't be called from a running loop. I spend a lot of time searching in the documentation but I couldn't find anything.

I'm running Python 3.7.3 and the error is the following

RuntimeError: asyncio.run() cannot be called from a running event loop

if anyone can point me to the right docs or code, that would be nice 👍

Hi, I'm trying to use aws provider to setup a domain, I don't know how to translate a alias in pulumi python, could someone give a pointer?

# Example DNS record using Route53.
# Route53 is not specifically required; any DNS host can be used.
resource "aws_route53_record" "example" {
  name    = "${aws_api_gateway_domain_name.example.domain_name}"
  type    = "A"
  zone_id = "${aws_route53_zone.example.id}"

  alias {
    evaluate_target_health = true
    name                   = "${aws_api_gateway_domain_name.example.cloudfront_domain_name}"
    zone_id                = "${aws_api_gateway_domain_name.example.cloudfront_zone_id}"
  }
}

Example from https://www.terraform.io/docs/providers/aws/r/api_gateway_domain_name.html

hey, is this expected: when doing pulumi up --refresh it would fail if there is a pod in failed state. but to me this makes no sense, because the UP should (at least in theory) introduce my changes to fix the problem.

Will we soon get a better experience writing pulumi in python? At the moment I prefer nodejs over python because intellisense works much better and drilling into resources for examples actually works.

Is pulumi/python still behind the other languages ? Last time I looked at pulumi JS and TS were far ahead of python in terms of i.e. examples ...\

@big-piano-35669 @white-balloon-205 I'm trying to understand the event loop especially when writing Python test. If I execute

my_resource.some_output.apply(lambda val: print(val))

, I get back another output that I believe has a future wrapped up in it that will execute my lambda. When does that actually get awaited?

I'm just starting with Pulumi so this may be a stupid question, but how am I supposed to be using apigateway.get_vpc_link() ? Do I have to import asyncio in order to make use of it? I'm not having any luck finding help with google

probably, here's what I've been using to get AKS data:

async def get_aks_credentials():
    result = await get_kubernetes_cluster(name=gen_name('aks'),
                                          resource_group_name=gen_name('rg')
                                          )
    return result.kube_config_raw

and then I'm just calling

get_aks_credentials()

in my code

that will work if you use it in a pulumi resource

I've got this so far:

import pulumi
from pulumi_aws import apigateway

async def get_vpclink():
  result = await apigateway.get_vpc_link(name="test-link")
  return result.id

rest_api = apigateway.RestApi('test-api-jenkins')

api_method = apigateway.Method('post', authorization='NONE', http_method='POST', resource_id=rest_api.root_resource_id, rest_api=rest_api.id)

integration = apigateway.Integration('post', connection_id=get_vpclink(), connection_type='VPC_LINK', http_method='POST', resource_id=rest_api.root_resource_id, rest_api=rest_api.id, type='HTTP_PROXY', uri='<https://test-api-jenkins.example.com/generic-webhook-trigger/invoke>')

pulumi.export('REST API ID', rest_api.id)

and I'm getting the

RuntimeError: cannot reuse already awaited coroutine

whats your pulumi\python versions?

Pulumi: v0.17.12 Python: v3.7.3

ok, i think i recall some issues with 3.5.x (which is not supported), probably doesnt apply to your case

I tried creating a new event loop and running get_vpclink() there but I got this error:

RuntimeError: Cannot run the event loop while another loop is running

Finally got it working. had to import asyncio and use ensure_future. Here's example code:

import asyncio
import pulumi
from pulumi_aws import apigateway

async def get_vpclink(name):
  result = await apigateway.get_vpc_link(name=name)
  return result.id

rest_api = apigateway.RestApi('test-api-jenkins')

api_method = apigateway.Method('post', authorization='NONE', http_method='POST',
                              resource_id=rest_api.root_resource_id,
                              rest_api=rest_api.id)

integration = apigateway.Integration('post', connection_id=asyncio.ensure_future(get_vpclink('test-jenkins')),
                                    connection_type='VPC_LINK', http_method='POST',
                                    resource_id=rest_api.root_resource_id,
                                    rest_api=rest_api.id, type='HTTP_PROXY',
                                    uri='<https://test-api-jenkins.example.com/generic-webhook-trigger/invoke>')

pulumi.export('REST API ID', rest_api.id)

weird

So now my issue is that I don't seem able to use these coroutines outside of a Pulumi resource. I'd like to have my program reach out and see if a REST API already exists with a given name and skip creating the resources for it if it does but I don't know if that's possible at this point

It also sucks that I can't call get_vpclink() once and get the id into a variable. Now when I implement the for loop it'll be doing that external call every time 😕
