This is a collection of modules that make it easier to provision Function resources on IBM Cloud Platform:

• namespace
• package
• action
• rule
• trigger
• cloud-function

Compatibility

This module is meant for use with Terraform 0.13.

Usage

Full examples are in the examples folder, but basic usage is as follows for creation of namespace and action :

provider "ibm" {
}

data "ibm_resource_group" "resource_group" {
  name = var.resource_group_name
}

module "namespace" {
  source  = "terraform-ibm-modules/function/ibm//modules/namespace"

  name              = var.name
  tags              = var.tags
  description       = var.description
  resource_group_id = data.ibm_resource_group.resource_group.id
}

Creating action:

provider "ibm" {
}

data "ibm_resource_group" "resource_group" {
  name = var.resource_group_name
}

module "action" {
  source = "terraform-ibm-function/function/ibm//modules/action"

  action_name         = var.action_name
  namespace_name      = var.namespace_name
  provision_namespace = true
  resource_group_id   = data.ibm_resource_group.resource_group.id

  exec = [{
    main = var.main
    kind = var.kind
    code_path = var.code_path
  }]

  limits = [{
    timeout = var.timeout
  }]

}

NOTE:

If we want to make use of a particular version of module, then set the argument "version" to respective module version.

All optional parameters by default will be set to null in respective example's varaible.tf file. If user wants to configure any optional paramter he has overwrite the default value.
