Equinix provider development

Requirements

  • Terraform 1.0.11+ (to run tests)
  • Go 1.18 (to build the provider plugin)
  • GNU Make (to build and test easier)

Building the provider

Note: This project uses Go Modules making it safe to work with it outside of your existing GOPATH. The instructions that follow assume a directory in your home directory outside of the standard GOPATH (i.e $HOME/development/).

  1. Clone Equinix Terraform Provider repository

    mkdir -p $HOME/development; cd $HOME/development 
git clone https://github.com/artraf/equinix-custom-ne.git

  2. Enter provider directory and compile it

    cd terraform-provider-equinix
make build

Testing the provider

  • to run unit tests, use make test target

    make test

  • to run acceptance tests, use make testacc target

    export EQUINIX_API_ENDPOINT=https://api.equinix.com
export EQUINIX_API_CLIENTID=someID
export EQUINIX_API_CLIENTSECRET=someSecret
make testacc

    NOTE: acceptance tests create resources on real infrastructure, thus may be subject for costs.

  • to manually clean resources that could leak from acceptance tests, use sweep target

    export EQUINIX_API_ENDPOINT=https://api.equinix.com
export EQUINIX_API_CLIENTID=someID
export EQUINIX_API_CLIENTSECRET=someSecre
make sweep

    Specific sweep targets can be swept as follows: make sweep SWEEPARGS="-sweep-run=equinix_metal_vrf" SWEEP="all".

Test parametrization

Acceptance tests can be parametrized by setting up various environmental variables.

Rationale behind parametrization is to allow running acceptance tests against different Equinix test environments.

  • TF_ACC_FABRIC_PRI_PORT_NAME alters default name of Equinix Fabric port for primary, Dot1Q encapsulated connections. Reflected by Fabric connection tests.
  • TF_ACC_FABRIC_SEC_PORT_NAME alters default name of Equinix Fabric port for secondary,Dot1Q encapsulated connections. Reflected by Fabric connection tests
  • TF_ACC_FABRIC_L2_AWS_SP_NAME alters default name of Equinix Fabric AWS seller profile. Reflected by Fabric connection tests
  • TF_ACC_FABRIC_L2_AWS_ACCOUNT_ID alters default authentication key of Equinix Fabric AWS l2 connection. Reflected by Fabric connection tests
  • TF_ACC_FABRIC_L2_AZURE_SP_NAME alters default name of Equinix Fabric Azure seller profile. Reflected by Fabric connection tests.
  • TF_ACC_FABRIC_L2_AZURE_XROUTE_SERVICE_KEY alters default authentication key of Equinix Fabric Azure l2 connection. Reflected by Fabric connection tests
  • TF_ACC_FABRIC_L2_GCP1_SP_NAME alters default name of Equinix Fabric GCP Interconnection Zone 1 seller profile. Reflected by Fabric connection tests.
  • TF_ACC_FABRIC_L2_GCP2_SP_NAME alters default name of Equinix Fabric GCP Interconnection Zone 2 seller profile. Reflected by Fabric connection tests.
  • TF_ACC_FABRIC_L2_GCP1_INTERCONN_SERVICE_KEY alters default authentication key of Equinix Fabric Google l2 connection primary. Reflected by Fabric connection tests
  • TF_ACC_FABRIC_L2_GCP2_INTERCONN_SERVICE_KEY alters default authentication key of Equinix Fabric Google l2 connection secondary. Reflected by Fabric connection tests
  • TF_ACC_METAL_DEDICATED_CONNECTION_ID defines the UUID of a Metal Dedicated Connection, necessary for Virtual Circuit testing.
  • TF_ACC_NETWORK_DEVICE_BILLING_ACCOUNT_NAME alters default billing account name for Network edge device primary. Reflected by Network Edge tests.
  • TF_ACC_NETWORK_DEVICE_SECONDARY_BILLING_ACCOUNT_NAME alters default billing account name for Network edge device secondary. Reflected by Network Edge tests.
  • TF_ACC_NETWORK_DEVICE_METRO alters default metro code for Network Edge resources. Reflected by Network Edge tests.
  • TF_ACC_NETWORK_DEVICE_SECONDARY_METRO alters default metro code for secondary Network Edge resources. Reflected by Network Edge tests.
  • TF_ACC_NETWORK_DEVICE_CSRSDWAN_LICENSE_FILE alters default path to CSR SD-WAN device license file. Reflected by Network Edge tests.
  • TF_ACC_NETWORK_DEVICE_VSRX_LICENSE_FILE alters default path to JUNIPER VSRX device license file. Reflected by Network Edge tests.
  • TF_ACC_NETWORK_SSH_PROJECT_ID alters default project identifier for Network Edge resources. Reflected by Network Edge tests.

Testing provider code

We have mostly acceptance tests in the provider. There's no point for you to run them all, but you should run the one covering the functionality which you change. The acceptance test run will cost you some money, so feel free to abstain. The acceptance test suite will be run for your PR during the review process.

To run an acceptance test, find the relevant test function in *_test.go (for example TestAccMetalDevice_Basic), and run it as

TF_ACC=1 go test -v -timeout=20m ./... -run=TestAccMetalDevice_Basic

If you want to see HTTP traffic, set TF_LOG=DEBUG, i.e.

TF_LOG=DEBUG TF_ACC=1 go test -v -timeout=20m ./... -run=TestAccMetalDevice_Basic

Testing the provider with Terraform

Once you've built the plugin binary (see Developing the provider above), it can be incorporated within your Terraform environment using the -plugin-dir option. Subsequent runs of Terraform will then use the plugin from your development environment.

terraform init -plugin-dir $GOPATH/bin

Manual provider installation

Note: manual provider installation is needed only for manual testing of custom built Equinix provider plugin.

Manual installation process differs depending on Terraform version. Run terraform version command to determine version of your Terraform installation.

Terraform 0.13 and newer

  1. Create developer.equinix.com/terraform/equinix/9.0.0/darwin_amd64 directories under:

    • ~/.terraform.d/plugins (Mac and Linux)
    • %APPDATA%\terraform.d\plugins (Windows)

    Note: adjust darwin_amd64 from above structure to match your os_arch

    mkdir -p ~/.terraform.d/plugins/developer.equinix.com/terraform/equinix/9.0.0/darwin_amd64

  2. Copy Equinix provider binary file there.

    cp terraform-provider-equinix ~/.terraform.d/plugins/developer.equinix.com/terraform/equinix/9.0.0/darwin_amd644

  3. In every Terraform template directory that uses Equinix provider, ship below terraform.tf file (in addition to other Terraform files)

    terraform {
  required_providers {
    equinix = {
      source = "developer.equinix.com/terraform/equinix"
      version = "9.0.0"
    }
  }
}

  4. Done!

    Local Equinix provider plugin will be used after terraform init command execution in Terraform template directory

Terraform 0.12 and older

  1. Copy provider binary to Terraform plugin directory

    • On Linux and Mac, copy to ~/.terraform.d/plugins

      cp terraform-provider-equinix_v1.0.0 ~/.terraform.d/plugins

    • On Windows, copy to %APPDATA%\terraform.d\plugins

      cp terraform-provider-equinix_v1.0.0.exe $APPDATA/terraform.d/plugins/

  2. Done!

    Local Equinix provider plugin will be used after terraform init command execution in selected Terraform template directory
