03/21/2023, 1:55 AMDo you mean a name? Why does a component resource need an id?
e
echoing-address-44214
03/21/2023, 1:55 AMargh yes
l
little-cartoon-10569
03/21/2023, 1:57 AMNames shouldn't be figured out by a component. They must be available at execution time, rather than deploy time (no Outputs allowed). And they must be guaranteed to not change. Looking up a value like this breaks both of these rules.

03/21/2023, 1:57 AMThe name of a resource is the first parameter passed into its constructor.
e
echoing-address-44214
03/21/2023, 1:58 AMAll of our resource names follow a pattern:
<dev|qa|stg|prd>-<region>-<the actual name>
echoing-address-44214
03/21/2023, 1:58 AMI want the user of my component to pass in the actual name
echoing-address-44214
03/21/2023, 1:58 AMI add the prefix
echoing-address-44214
03/21/2023, 1:59 AMThis way I can ensure centrally that the naming schema is enforced
l
little-cartoon-10569
03/21/2023, 1:59 AMDon't do that. Those other values are obvious from the project and stack names. No need to duplicate that data.
little-cartoon-10569
03/21/2023, 1:59 AMAnd if you have to, you can put those values in tags or similar.
little-cartoon-10569
03/21/2023, 1:59 AMNot in the resource names.
little-cartoon-10569
03/21/2023, 2:00 AMHaving long resource names makes it hard to read, and can in a few cases break your cloud provider. Most resources use the names in the provider-specific id or name, and some of those names or ids are length-limited.
e
echoing-address-44214
03/21/2023, 2:01 AMI am aware of those limits. We are doing it for years and makes it really easy if you have to do reservations etc

03/21/2023, 2:01 AMWhat happens if two stacks use the same name?
l
little-cartoon-10569
03/21/2023, 2:02 AMNo problems. That's what Pulumi puts suffixes there for.
e
echoing-address-44214
03/21/2023, 2:02 AMSo the suffix will be added even on my compoent resource?
l
little-cartoon-10569
03/21/2023, 2:02 AMAnyway, to answer your question: convert that async lookup to a simple typescript function. Move the logic into reusable code, instead of a remove provider.
little-cartoon-10569
03/21/2023, 2:02 AMYes
little-cartoon-10569
03/21/2023, 2:03 AMWait, what is it that you are asking there?
little-cartoon-10569
03/21/2023, 2:03 AMAre you asking if the component name will have a random suffix?
little-cartoon-10569
03/21/2023, 2:04 AMComponent names don't have a random suffix. Only cloud names.
little-cartoon-10569
03/21/2023, 2:04 AMComponents are internal to a stack, therefore there can never be inter-stack clashes.
e
echoing-address-44214
03/21/2023, 2:04 AM Copy code
super("ruwen/RedisCluster", name, {}, opts);echoing-address-44214
03/21/2023, 2:05 AMLet's say someone deploys their code in two regions in the same dev environment. For tname they use my-redis. Will it clash?
l
little-cartoon-10569
03/21/2023, 2:05 AMThe URNs have the stack name in them. Uniqueness is guaranteed.
little-cartoon-10569
03/21/2023, 2:05 AMNo, it won't clash.
little-cartoon-10569
03/21/2023, 2:06 AMThe URN will be
urn:pulumi:stackName::projectName::typeName::namelittle-cartoon-10569
03/21/2023, 2:06 AMSince the stack name is in there, there is no clash.
e
echoing-address-44214
03/21/2023, 2:06 AMBecause the docs say
name – The unique name of the resource.echoing-address-44214
03/21/2023, 2:06 AMah ok
l
little-cartoon-10569
03/21/2023, 2:06 AMUnique within a given project/stack/type triple.
e
echoing-address-44214
03/21/2023, 2:06 AMeasy 🙂
l
little-cartoon-10569
03/21/2023, 2:07 AMYou can have loads of resources with the same name, so long as they're all different types.
e
echoing-address-44214
03/21/2023, 2:07 AMI thought it had to be unique within the state file
l
little-cartoon-10569
03/21/2023, 2:07 AMThe URN needs to be unique within the state file. The name only needs to be unique within the (type + stack + project).
e
echoing-address-44214
03/21/2023, 2:08 AMAh makes sense. That simplifies my life! Thank you!
