Hi I'm creating a custom ComponentResource in python, and I'm not understanding if I'm supposed to declare my custom arg class like this:

Copy code

@pulumi.input_type
class RoleMappingArgs:
    groups: pulumi.Input[Sequence[pulumi.Input[str]]] = pulumi.property("groups")
    role_arn: pulumi.Input[str] = pulumi.property("role_arn")
    username: pulumi.Input[str] = pulumi.property("username")

Or is this something I should use only for cross language components? I can just declare nested args classes and the Outputs will be respected correctly?

I have a colleague who is experiencing a weird issue with their local Pulumi dev env. when they run

pulumi up

on a stack that references other stacks, the stack reference is empty. in this case, it’s a reference to an AWS region. additionally, when they run

pulumi config

the output is empty, where as when I run it on the same stack I do see the expected config output

Any idea how to diagnose this further:

Copy code

Diagnostics:
  pulumi:pulumi:Stack (tlayen-prod):
    error: missing executor /Users/jason/go/bin/pulumi-language-python-exec

error: failed to load language plugin python: could not read plugin [/Users/jason/go/bin/pulumi-language-python] stdout: EOF

It is the same error as https://github.com/pulumi/pulumi/issues/1956 but I don’t get how to fix it. It was working fine until I upgraded pulumi via brew.

Hi there! I am using Pulumi to create some custom infrastructure and am having trouble accessing the outputs of my resources. On the docs (https://www.pulumi.com/docs/intro/concepts/resources/#dynamic-resource-outputs) it says that what I am doing should be correct, but there is also little mention of how to actually access the outputs, so I could be wrong. This is what my resource and provider look like; am I doing anything wrong?

Copy code

class AccountProvider(ResourceProvider):
    def __init__(self, props):
        self.parent_client = Client(props["sid"], props["auth_token"])
    def create(self, props):
        subaccount = self.parent_client.api.accounts.create(friendly_name="{}-{}".format(props["name"], stack))
        return CreateResult(id_=subaccount.sid, outs={'sid':subaccount.sid, 'auth_token':subaccount.auth_token})
    def delete(self, id, props):
        self.parent_client.api.accounts(id).update(status="closed")

class Account(Resource):
    sid: Output[str]
    auth_token: Output[str]
    def __init__(self, name: str, props,  opts: Optional[ResourceOptions] = None):
        super().__init__(AccountProvider(props), name, {"name":name, 'sid':None, 'auth_token':None}, opts)

new_account = Account("new_account1", props=AccountCredentials(sid=account_sid, auth_token=auth_token))

does anyone know how to properly setup IntelliSense/autocomplete/code hint for pulumi python on VS Code? the built in Python Intellisense isn't giving me any code suggestion specific on pulumi or pulumi_aws

Had a quick Q about auto-casing/argument passing into resource constructors. I notice many of Pulumi's args are auto-snake-cased as a dict of args that can be passed into a constructor, for example,

Copy code

ProbeArgs(
                    http_get=HTTPGetActionArgs(
                        path="/healthz",
                        port=DEFAULT_SERVICE_PORTS_SPEC["http"]["port"],
                        scheme="HTTP",
                    ),
                    failure_threshold=2,
                    initial_delay_seconds=60,
                    period_seconds=30,
                    success_threshold=1,
                    timeout_seconds=5,
                ),

is it acceptable practice to skip using the verbose class & arg and go straight to constructing things like this?

Copy code

liveness_probe={"http_get": {"path": "/healthz", "port": DEFAULT_SERVICE_PORTS_SPEC["http"]["port"], "scheme": "http"}, "failure_threshold": 2, "initial_delay_sections": 60, "period_seconds": 30, "success_threshold": 1, "timeout_seconds": 5}

the reason I'm asking is, from a javascripter/typescripter perspective, the second is much more "obvious" what is going on, at least with respect to kubernetes, since the object structure appears to match the meta schema structure of a kubernetes' JSON/YAML API [I forgot the technical term for this]

gorgeous-minister-41131

08/19/2021, 8:58 PM

it's just that python prefers "snake case" so all of the fields of objects in the k8s API struct are 'translated' anyway...

gorgeous-minister-41131

08/19/2021, 8:59 PM

Plus, and maybe this is actually by design, it lets a more common system "generate" the various Args for different things, irrespective of the underlying language dialect chosen for a particular set of resources managed with pulumi. E.g. mix and matching typescript, golang, python etc, and using a common return map for generating allthethings

FYI latest pulumi release includes this which allows you to customize the type names for dynamic resources

I'm creating multiple instances (via for loop) of a ManagedNodeGroup. Is there some way of parallelizing it? Current behaviour is linear (expected) but takes long to deploy many of them.

Has anyone here been able to create an ec2 instance resource using the aws.ec2 module and increase the drive using the root_block_device variable? Im getting the following error:

Copy code

AssertionError: Unexpected type. Expected 'list' got '<class 'pulumi_aws.ec2._inputs.InstanceRootBlockDeviceArgs'>'
    error: an unhandled error occurred: Program exited with non-zero exit code: 1

In pulumi I cant figure out how to convert the class to a list, Or even if I should be doing that. Im sure there's a pulumi way of doing this. Please point me in the right direction. Code:

Copy code

for i in range(5):
    server = aws.ec2.Instance(f"webserver-{i:03}",
        ami=ami.id,
        iam_instance_profile='ec2_role',
        instance_type=size,
        key_name=sshKey,
        root_block_device=[aws.ec2.InstanceRootBlockDeviceArgs(
            device_name='/dev/sda1',
            volume_size=100,
            volume_type='gp3',
            )],
        subnet_id=['subnet-xxxxxxxxxxxxxxxx'],
        tags={
            "Name": f"webserver-{i:03}",
            "Purpose": "webapp"
        },
        volume_tags={

Is there a away to make Pulumi wait for an ECS deploy to fully complete after updating a container+task definition instead of just saying its successful right away after the task definition is updated?

Morning, I am having an issue with the vpc_endpoint module of pulumi. How can I add multiple subnets to the endpoint. When I tired with the assocaition module it just overrode the existing subnet instead of adding another one?

Hello Pulumi/python people! Trying to create an AlertCondition using some of the example code on this page There is some code in the Example Usage section, under the python tab that contains the following:

Copy code

import pulumi
import pulumi_newrelic as newrelic

foo_monitor = newrelic.synthetics.get_monitor(name="foo")
foo_alert_condition = newrelic.synthetics.AlertCondition("fooAlertCondition",
    policy_id=newrelic_alert_policy["foo"]["id"],
    monitor_id=foo_monitor.id,
    runbook_url="<https://www.example.com>")

I was wondering what “newrelic_alert_policy” is. A function, variable? It isn’t defined in the example. All I’m trying to do is create a simple alert for some simple synthetic monitors I’ve put together.

hi peeps! I'm trying to create a web app, and then use listWebAppPublishingCredentials to get the scm_uri value, much like this person is trying to do here: https://stackoverflow.com/questions/64557665/pulumi-add-azure-web-app-service-web-hook-to-azure-container-registry-for-conti The proposed solution makes sense (it's JS):

Copy code

const webhook = pulumi.all([resourceGroup.name, webApp.name])
    .apply(([resourceGroupName, name]) => 
        web.listWebAppPublishingCredentials({ resourceGroupName, name }))
    .apply(creds => creds.scmUri + "/docker/hook");

But when trying to run the same in python, it's basically saying "The web app resource was not found", which makes sense... because I'm trying to create it right before. What would be the right way to solve this? One option is to create a different stack and have them run one after the other but that's something I'd really, really like to avoid.

so, after hitting my head against the wall a couple of times: The name is deterministically generated by pulumi (i.e. doesn't need the resource to exist to get a name), it doesn't know to wait to fetch the web app publishing credentials, the trick is to include the

webApp.id

in the output interpolation like

pulumi.all([resourceGroup.name, webApp.name, webApp.id])

even if it's not used, so it's forced to wait

I'm trying to handle output in the form of a list/dict:

Copy code

+ subnets: [
+     [0]: "10.2.0.0/22"
+     [1]: "10.4.0.0/22"
+     [2]: "10.6.0.0/22"
+     [3]: "10.8.0.0/22"
+     [4]: "10.10.0.0/22"
+     [5]: "10.12.0.0/22"
+     [6]: "10.14.0.0/22"
]

I can set a value by using the index (i.e.

['subnets'][0]

) I want to iterate over the subnets to create them but I can't use a for loop because

'Output' object is not iterable

How can I use these values in the output?

crooked-pillow-11944

09/13/2021, 2:59 PM

Does somebody have an example of using

Output.all

with a list? The documentation says that you would use it's

Output

with an

.apply

but I'm uncertain of a practical application for this

Pulumi tries to delete the existing resouces (iam role & policies) when we run

pulumi up

for the upgrades or refresh.

Does the pulumi kubernetes library have a helper method built in for making a string “name safe” (e.g. dns-name compliant)? I can easily make my own but wasn’t sur eif the pulumi_kubernetes lib contained something like this.

Just trying to avoid re-inventing the wheel if pulumi already has a validator for the pulumi_kubernetes provider 🙂
