No way of interconnecting two ibm cloud functions

[itraveribon]

Hi there,

I am trying to make an IBM cloud function A to call another function B. For that, I have to give the URL of B as input parameter to the function A. However, I was not able to find a way to get this URL. In the UI of IBM Cloud this URL can be found under Cloud Functions / Actions / <name_of_function> / Endpoints. In this page we can see a box called REST API. Is there anyway to get this data (the URL and the API-Key) in terraform?

Terraform Version

v0.12.25

Affected Resource(s)

Please list the resources as a list, for example:

• ibm_function_action

Terraform Configuration Files

Here I leave an example of I would like to do but I do not find the way:

resource "ibm_function_action" "B" {
  name = "${ibm_function_package.package.name}/${var.actionName}"

  exec {
    kind = "itraveribon/ibmcloud"
    image = file("function_b.py")
  }
}

resource "ibm_function_action" "A" {
  name = "${ibm_function_package.package.name}/${var.actionName}"

  exec {
    kind = "itraveribon/ibmcloud"
    image = file("function_a.py")
  }
user_defined_parameters = <<EOF
  [
    {
        "key": "function_b_url",
        "value":"${ibm_function_action.B.??URL??}"
    },
 ]
  EOF
}

@hkantare Will there be a way to get an output of cloud functions endpoint url in terraform?

[anilkumarnagaraj]

Currently, Terraform doesn't provide an endpoint URL for the actions. In our next release, we will provide support for generating an action endpoint URL.

Now we exposed the target_endpoint_url attribute
