    So i can't use any of the outputs in the filter parameter right?

    i’m asking if 
    type(project.project_id) == Output

    okay cool

    05/20/2020, 5:39 PM
    you want to use 
    Output.apply()
  • s

    sparse-state-34229

    05/20/2020, 5:40 PM
    so something like
  • s

    sparse-state-34229

    05/20/2020, 5:41 PM
    Output.all([project.project_id]).apply(lambda x: gcp.projects.get_project(filter=f"project_id:{x[0][0]} AND …"))
  • s

    05/20/2020, 5:41 PM
    you may have to play with it and figure out the exact form for what you need

    05/20/2020, 5:43 PM
    note 
    x[0][0]
    - the argument passed to 
    .apply()
    is a list (but you may only need 
    x[0]
    )

    05/20/2020, 5:45 PM
    def user_data(self):
        user_data_tpl = Template(BASE_USERDATA_TPL)

        return Output.all([self.vpc.id]).apply(
            lambda x: user_data_tpl.render(
                dns_domain=self.vpc.dns_domain,
                vpc_cidr=self.vpc.cidr_block,
                vpc_id=x[0][0],
                vpc_name=self.vpc.name,

    also might i suggest backtics for pasting code (one or three, same as github)

    05/21/2020, 4:46 PM
    yes but at the start there is no vpc with this tags the pulumi need to craete many vpc with the tags but when there is no vpcs its failed insted of return empty array of ids

    getting the cidr_block of each vpc. ok, if there is no some solution to resolve it i will catch the exception. Thanks

    if the VPC doesn’t exist how can you get its CIDR block?

    @hundreds-dog-95098 Unfortunately, these "not found" exceptions from lookup functions and and 
    <resource>.get()
    calls cannot be caught and handled with a try/catch. There is an issue open regarding this at https://github.com/pulumi/pulumi/issues/3364 if you want to subscribe to it or add additional use case information.

    if these are pulumi-managed VPCs, you should have the CIDR block data available without querying AWS, tho

    Any of the python guru's knows how to get the string value out of random.RandomString 
    random_id = random.RandomString(
    resource_name='project-unique-id',
    length=8,
    lower=True,
    upper=False,
    special=False,
    min_numeric=4
)
    is there a way to extract the string value from random_id.result?

yes

you need .apply possibly with 
Output.all()
what are you doing with the value?

what i need to do is to get the subnet back later, i know it sounds problematic , but its required subnet = gcp.compute.get_subnetwork( name=subnet_name, project=project_id, region=gcp_region ) if subnet.self_link: return subnet.ip_cidr_range else: return allocate_new_cidr(base_cidr_range)
name accepts only string i tried passing another output but no success
name of the subnet contains the random id i generated before
s

sparse-state-34229

05/24/2020, 4:11 PM
here is an example of how I do it:
return Output.all([self.vpc.id]).apply(
            lambda x: user_data_tpl.render(
                dns_domain=self.vpc.dns_domain,
                vpc_cidr=self.vpc.cidr_block,
                vpc_id=x[0][0],
                vpc_name=self.vpc.name,
            ).encode("utf-8")
        )
note the 
x[0][0]

bulky-match-1583

05/24/2020, 4:12 PM
yes i tried
the problem that is returns another output and thre is no way to check if the subnet really exists 🙂

sparse-state-34229

05/24/2020, 4:15 PM
that’s fine, you just can’t print it
b

bulky-match-1583

05/24/2020, 4:17 PM
its and an empty output object , but seems i don't have a way to verify if something was found
s

sparse-state-34229

05/24/2020, 4:17 PM
what do you mean by verify?
b

bulky-match-1583

05/24/2020, 4:19 PM
if i pass just a string to subnet name 
subnet = gcp.compute.get_subnetwork(
    name='some-subnet-that-exists',
    project=my-proejct-id,
    region=gcp_region
)
if subnet exists i can verify with 
if subnet.self_link:
    return subnet.ip_cidr_range
doesn't seem to work with apply
s

sparse-state-34229

05/24/2020, 4:22 PM
in what way does it not work?
b

bulky-match-1583

05/24/2020, 4:23 PM
subnet = pulumi.Output.all([config.project_id]).apply(
    lambda x: gcp.compute.get_subnetwork(
        name=f'{x[0][0]}-subnet',
        project=x[0][0],
        region=config.gcp_region
    )
)
if subnet.self_link:
    return subnet.ip_cidr_range
if subnet.self_link always true even if it doesn't exist
i'm missing someting
s

sparse-state-34229

05/24/2020, 4:23 PM
subnet.self_link
is bool?
hmm
b

bulky-match-1583

05/24/2020, 4:24 PM
it jus tests that its not None
without apply with string in name works like a charm
s

sparse-state-34229

05/24/2020, 4:24 PM
well, there are ways that can be true without it being 
None
might be prudent to test explicitly, but i’m not sure that will help here
