Hi, I’m writing terraform provider. I want up update resource.
Resource has computed parameter guid_id. For update I need to have this parameter as input.
Do we have possibility to describe schema for every operation (For CreateContent, ReadContext,UpdateContect, DeleteContext)? Then I will describe updatecontext schema accordingly
Dmitriy
Um, no? Resources have one schema, which defines how a user is supposed to write them in their Terraform files, and what is stored in the state. That is inherently common to all operations.
Thanks for the response.
How I should to describe guid attribute.
It is created in POST method( I described as calculated) and used in PUT( not clear how to described)
Terraform throws error:
Can’t configure a value for “guid_id”: its value will be decided automatically based on the result of applying this configuration.
Best regards,
Dmitriy
Please show your actual code.
Hi,
here is main.tf
terraform {
required_providers {
orch = {
version = “1.0.1”
source = “localhost/company/orch”
}
}
}
provider “orch” {
}
variable “iaas_name” {
description=“Name of iaas provider”
}
variable “iaas_url” {
description=“Url of iaas provider”
}
variable “iaas_update_url” {
description=“Url of iaas provider”
}
variable “iaas_type” {
description=“Url of iaas provider”
}
variable “iaas_guid” {
description=“guild of iaas provider”
}
resource “orch_iaas_resource” “my_iaas” {
type=var.iaas_type
name=var.iaas_name
url=var.iaas_url
}
output “my_iaas_output” {
value=[orch_iaas_resource.my_iaas.guid_id,orch_iaas_resource.my_iaas.name]
}
resource “orch_iaas_resource” “my_iaas1” {
guid_id=orch_iaas_resource.my_iaas.guid_id
type=var.iaas_type
name=var.iaas_name
url=var.iaas_update_url
}
output “my_iaas_output1” {
value=[orch_iaas_resource.my_iaas1.guid_id,orch_iaas_resource.my_iaas1.url]
}
resource my_iaas created resource. guid_id has been generated
Then my_iaas1 updated the same resource. Call has been failed with the error
When expanding the plan for orch_iaas_resource.my_iaas1 to include new values learned so far during apply, provider "localhost/company/orch
" produced an
│ invalid new value for .guid_id: was null, but now cty.StringVal(“a93a5416-d9fa-4191-8fd7-11751449ea20”).
In different topic someone advised to have update in the same block.
I will try to implement it. I described guid_id as optional.
If you have an another idea how to update resource where key is generated please let me know.
Best regards,
Dmitriy
Hi @dtrvno 
Are you able to share the code for your provider? Specifically the schema and the code you are using in the CRUD operations?
