I am struggling with the same

Output

object, and I have a feeling of moving in circles 🙂

api_service = Service(
    opts=ResourceOptions(depends_on=[api_deployment]),
    resource_name="api",
    spec={
        "type": "ClusterIP",
        "selector": {"app": "api-deployment"},
        "ports": [port_map(api_port)],
    }
)
# Name is something like: "api-vvf3g61k"
# Tried:
srv_name1 = api_service.metadata.name
srv_name2 = Output.all([api_service.metadata]).apply(lambda x: x.name)
srv_name3 = Output.all([api_service.metadata.name]).apply(lambda x: x)
srv_name4 = Output.all([api_service.status]).apply(lambda x: str(x))

print("srv_name1:" + pformat(srv_name1))
print("srv_name2:" + pformat(srv_name2))
print("srv_name3:" + pformat(srv_name3))
print("srv_name4:" + pformat(srv_name4))

I want to use that name in an env var to configure another deployment …

you can’t print

Diagnostics:
  pulumi:pulumi:Stack (central-infra-central-danlaptop-docker-desktop):
    srv_name1:<pulumi.output.Output object at 0x10e3e5710>
    srv_name2:<pulumi.output.Output object at 0x10e3f1390>
    srv_name3:<pulumi.output.Output object at 0x10e3f1d10>
    srv_name4:<pulumi.output.Output object at 0x10e3fa990>

also use f strings

lemon-night-89661

05/24/2020, 9:38 PM

It will get caught by the “Diagnosstics”

Thanks @sparse-state-34229. Is it only the printing that trips me?

lemon-night-89661

05/24/2020, 9:40 PM

Or is there something else?

sparse-state-34229

05/24/2020, 9:40 PM

maybe. how are you trying to use it? specifically with “I want to use that name in an env var”

There’s another service that will connect to the internal name of this service.

lemon-night-89661

05/24/2020, 9:41 PM

And I need to configure that other internal’s services environment with something like

API_ENDPOINT=<http://api-vvf3g61k:8080>

sparse-state-34229

05/24/2020, 9:42 PM

okay, cool…so that is the “what” you want to do, now “HOW” are you planning to do it?

lemon-night-89661

05/24/2020, 9:42 PM

If I set

metadata.name

api

for example, I will be able to use ``API_ENDPOINT=http://api:8080` and this works.

lemon-night-89661

05/24/2020, 9:42 PM

Now I’d rather not set it fixed

sparse-state-34229

05/24/2020, 9:42 PM

code / pseudocode is always good 🙂

lemon-night-89661

05/24/2020, 9:43 PM

But let pulumi autogenerate a name for the service

lemon-night-89661

05/24/2020, 9:43 PM

Maybe my strategy is not pulumi-style 🙂

srv_name1 = api_service.metadata.name

what are you doing with

srv_name1

after this?

lemon-night-89661

05/24/2020, 9:46 PM

serv2_deployment = Deployment(
...
     "spec": {
...
         "containers": [
             {
...
                 "env": [
                     {"name": "API_HOST", "value": "<http://%s>" % srv_name1},
                 ],
...

lemon-night-89661

05/24/2020, 9:46 PM

Use it in another deployment

lemon-night-89661

05/24/2020, 9:47 PM

Does it make sense?

sparse-state-34229

05/24/2020, 9:47 PM

and that isn’t working for you, correct?

lemon-night-89661

05/24/2020, 9:47 PM

Correct

lemon-night-89661

05/24/2020, 9:48 PM

I get something like

http://<pulumi.output.Output object at 0x10e3fe850>

🙂

sparse-state-34229

05/24/2020, 9:48 PM

try something like

serv2_deployment = Output.all([srv_name1]).apply(lambda s: Deployment("""json here""")) # replace srv_name1 with s[0][0]

lemon-night-89661

05/24/2020, 9:49 PM

ok. let me try this.

sparse-state-34229

05/24/2020, 9:50 PM

at that point you may be able to reference

api_service.metadata.name

unless you use

srv_name1

elsewhere

that is one way I do this

sparse-state-34229

05/24/2020, 9:52 PM

self.vpc

is a

pulumi_aws.ec2.Vpc

object

sparse-state-34229

05/24/2020, 9:53 PM

if I passed

self.vpc.id

directly the jinja template output would look like your URL
