Terraform provider for VMware vRealize Automation 7

Introduction

A self-contained deployable integration between Terraform and vRealize Automation (vRA) which allows Terraform users to request/provision entitled vRA catalog items using Terraform. Supports Terraform destroying vRA provisioned resources.

Requirements

Using the provider

See the vra7 documentation to get started using the vRealize Automation 7 provider.

See vra7_deployment resource examples [here] (examples/README.md)

Execution

These are the Terraform commands that can be used for the vRA plugin:

  • terraform init - The init command is used to initialize a working directory containing Terraform configuration files.
  • terraform plan - Plan command shows plan for resources like how many resources will be provisioned and how many will be destroyed.
  • terraform apply - apply is responsible to execute actual calls to provision resources.
  • terraform refresh - By using the refresh command you can check the status of the request.
  • terraform show - show will set a console output for resource configuration and request status.
  • terraform destroy - destroy command will destroy all the resources present in terraform configuration file.

Navigate to the location where main.tf and binary are placed and use the above commands as needed.

Upgrading the provider

The vra7 provider doesn't upgrade automatically once you've started using it. After a new release you can run

terraform init -upgrade

to upgrade to the latest stable version of the vra7 provider. See the Terraform website for more information on provider upgrades, and how to set version constraints on your provider.

Migrating from previous versions to version 1.0.0, issues fixed and enhancements

There are some schema changes in the provider version 1.0.0. These changes are made to support vra7 deployment Day 2 actions, detailed information of the deployment in the state file, getting access to more deployment and resource level properties, esp. ip_address, etc. See the release notes for more detail.

Previous main.tf file

provider "vra7" {
  username = var.username
  password = var.password
  tenant   = var.tenant
  host     = var.host
}

resource "vra7_deployment" "this" {
    count                      = 1
    catalog_item_name          = "multi_machine_catalog"
    businessgroup_name         = Development
    wait_timeout               = 20
    deployment_configuration = {
        "_leaseDays"                 = "15"                   //number of lease days
        "BPCustomProp"               = "custom depl prop"     //custom property in BP required while requesting a catalog item
        "Container"                  = "App.Container"        //property of a property group
        "Container.Auth.User"        = "var.container_user"   //property of a property group
        "Container.Auth.Password"    = "var.container_pw"     //property of a property group
        "Container.Connection.Port"  = "var.container_port"   //property of a property group
    }

    resource_configuration = {
        "Windows.cpu"            = "2"                //Windows Machine CPU
        "Windows.memory"         = "1024"             //Windows Machine memory
        "Windows.vm_custom_prop" = "a custom prop"    //Windows custom property called vm_custom_property
        "Windows._cluster"       = "2"                //Windows cluster size
        "Linux.cpu"              = "2"                //Linux Machine CPU
        "http.hostname"          = "xyz.com"          //HTTP (apache) hostname
        "http.network_mode"      = "bridge"           //HTTP (apache) network mode
    }
}

Migrating to the latest version would require to make the following changes in the TF confile(main.tf).

  • _leaseDays is moved out of of deployment_configuration and added as a property in the schema. The name of the property is lease_days. This can be changed for Change Lease Day 2 action.
  • We create a resource_configuration block for each component. There are three components, Windows, Linux and http. For instance, the resource_configuration for Windows component would look like this:
resource_configuration {
    component_name              = "Windows"          //This is the component name and need not be prefixed with all properties
    cluster                     = 2                  //cluster is added as a property in the schema. Modifying it will do the
                                                     // Scale In/Out Day 2 actions
    configuration = {
        cpu                     = 2
        memory                  = 1024
        vm_custom_prop          = "a custom prop"
    }
}
  • _cluster is added as a property in the schema. It can be modified for Scale In/Scale Out Day 2 actions
  • Support for deployemnt and resource properties of type array of strings in the blocks deployment_configuration as well as configuration under resource_configuration respectively as shown in the example below.
  • ip_address need not be added in the main.tf. It can be accessed from the state file. It is added as a property in the resource_configuration -> instances schema. Please refer to the documentation.

The new main.tf file would look as follows:

provider "vra7" {
  username = var.username
  password = var.password
  tenant   = var.tenant
  host     = var.host
}

resource "vra7_deployment" "this" {
    count                      = 1
    catalog_item_name          = "multi_machine_catalog"
    businessgroup_name         = Development
    wait_timeout               = 20
    lease_days                 = 15                           //number of lease days

    deployment_configuration = {
        "BPCustomProp"               = "custom depl prop"     //custom property in BP required while requesting a catalog item
        "Container"                  = "App.Container"        //property of a property group
        "Container.Auth.User"        = "var.container_user"   //property of a property group
        "Container.Auth.Password"    = "var.container_pw"     //property of a property group
        "Container.Connection.Port"  = "var.container_port"   //property of a property group
        "businessGroups" = <<EOF                              //this is an example to property of type array of strings
        [
            "bgTest1",
            "bgTest2"
        ]
        EOF
    }

    resource_configuration {
        component_name              = "Windows"       //This is the component name and need not be prefixed with all properties
        cluster                     = 2               //cluster is added as a property in the schema. Modifying it will do the
                                                      // Scale In/Out Day 2 actions
        configuration = {
            cpu                     = 2
            memory                  = 1024
            vm_custom_prop          = "a custom prop"
        }
    }

    resource_configuration {
        component_name              = "Linux"      //This is the component name and need not be prefixed with all properties
        configuration = {
            cpu                     = 2
            security_tag = <<EOF                   //this is an example to property of type array of strings
            [
                "dev_sg",
                "prod_sg"
            ]
            EOF
        }
    }

    resource_configuration {
        component_name              = "http"      //This is the component name and need not be prefixed with all properties
        configuration = {
            hostname                = "xyz.com"          //HTTP (apache) hostname
            network_mode            = "bridge"           //HTTP (apache) network mode
        }
    }
}

Outputs

The resource_configuration block has an instances block that is a list of all the instances/VMs corresponding to a component. The instance list size is nothing but the custer size.

For example, after the deployment is created using the above config file, the resource_configuration list size will be 3. And the instances list size in the resource configuration map corresonding to the component "Windows" will be 2. This is because the cluster size is 2 and it creates 2 VMs with that configuration.

Sample outputs:

output "ip_address" { value = vra7_deployment.this[].resource_configuration[].instances[*].properties.ip_address }

output "component" { value = vra7_deployment.this[].resource_configuration[].component_name }

output "vm_name" { value = vra7_deployment.this[].resource_configuration[].instances[*].properties.name }

Expected sample outputs (based on the above main.tf, ip_address and vm_names are mock data below):

ip_address = [ [ [ "10.xxx.xxx.xxx", "10.xxx.xxx.xxx", ], [ "10.xxx.xxx.xxx" ], [ "10.xxx.xxx.xxx" ], ], ]

component = [ [ "Windows", "Linux", "http", ], ]

vm_name = [ [ [ "Windows-machine1-2048", "Windows-machine2-2049", ], [ "Linux-machine1-2050", ], [ "http-machine1-2051", ], ], ]

Import vra7_deployment

Import functionality is now supported for the vra7_deployment resource. If there is an exiting deployment, it can be imported by catalog item request id.

main.tf

provider "vra7" {
  username = var.username
  password = var.password
  tenant   = var.tenant
  host     = var.host
}

resource vra7_deployment "this" {
    // the properties can be added once the import is completed by referring to the state file
}

terraform import vra7_deployment.this <request_id>

Data source vra7_deployment

A data source for vra7_deployment can also be created using either deployment ID or catalog item request id. Refer to the documentation here

Building the provider

Clone repository to: $GOPATH/src/github.com/vmware/terraform-provider-vra7

$ mkdir -p $GOPATH/src/github.com/terraform-providers; cd $GOPATH/src/github.com/terraform-providers
$ git clone git@github.com:terraform-providers/terraform-provider-vra7

Enter the provider directory and build the provider

$ cd $GOPATH/src/github.com/vmware/terraform-provider-vra7
$ make build

Developing the provider

If you wish to work on the provider, you'll first need Go installed on your machine (version 1.11.4+ is required). You'll also need to correctly setup a GOPATH, as well as adding $GOPATH/bin to your $PATH.

To compile the provider, run make build. This will build the provider and put the provider binary in the $GOPATH/bin directory.

$ make build
...
$ $GOPATH/bin/terraform-provider-vra7
...
