🐙 Terraform Provider for Octopus Deploy

⚠️ Warning

The Terraform Provider for Octopus Deploy is under active development. Its functionalty can and will change; it is a v0.* product until its robustness can be assured. Please be aware that types like resources can and will be modified over time. It is strongly recommended to validate and plan configuration prior to committing changes via apply.

About

This repository contains the source code for the Terraform Provider for Octopus Deploy. It supports provisioning/configuring of Octopus Deploy instances via Terraform. Documentation and guides for using this provider are located on the Terraform Registry: Documentation.

🪄 Installation and Configuration

The Terraform Provider for Octopus Deploy is available via the Terraform Registry: OctopusDeployLabs/octopusdeploy. To install this provider, copy and paste this code into your Terraform configuration:

terraform {
  required_providers {
    octopusdeploy = {
      source = "OctopusDeployLabs/octopusdeploy"
      version = "version-number" # example: 0.21.1
    }
  }
}

provider "octopusdeploy" {
  # configuration options
  address  = "https://octopus.example.com"     # (required; string) the service endpoint of the Octopus REST API
  api_key  = "API-XXXXXXXXXXXXX"               # (required; string) the API key to use with the Octopus REST API
  space_id = "Spaces-1"                        # (optional; string) the space ID in Octopus Deploy
}

If space_id is not specified the Terraform Provider for Octopus Deploy will assume the default space.

Environment Variables

You can provide your Octopus Server configuration via the OCTOPUS_URL and OCTOPUS_APIKEY environment variables, representing your Octopus Server address and API Key, respectively.

provider "octopusdeploy" {}

Run terraform init to initialize this provider and enable resource management.

🛠 Build Instructions

A build of this Terraform Provider can be created using the Makefile provided in the source:

$ make

This will generate a binary that will be installed to the local plugins folder. Once installed, the provider may be used through the following configuration:

terraform {
  required_providers {
    octopusdeploy = {
      source  = "octopus.com/com/octopusdeploy"
      version = "0.7.63"
    }
  }
}

provider "octopusdeploy" {
  address  = # address
  api_key  = # API key
  space_id = # space ID
}

After the provider has been built and saved to the local plugins folder, it may be used after initialization:

$ terraform init

Terraform will scan the local plugins folder directory structure (first) to qualify the source name provided in your Terraform configuration. If it can resolve this name then the local copy will be initialized for use with Terraform. Otherwise, it will scan the Terraform Registry.

⚠️ The version number specified in your Terraform configuration MUST match the version number specified in the Makefile. Futhermore, this version MUST either be incremented for each local re-build; otherwise, Terraform will use the cached version of the provider in the .terraform folder. Alternatively, you can simply delete the folder and re-run the terraform init command.

Debugging

If you want to debug the provider follow these steps!

Prerequisites

• Terraform provider is configured to use the local version e.g. "octopus.com/com/octopusdeploy"

terraform {
  required_providers {
    octopusdeploy = {
      source  = "octopus.com/com/octopusdeploy"
      version = "0.7.63"
    }
  }
}

• Optional - Install delve https://github.com/go-delve/delve

Via Goland

1. Debug the provided run configuration Run provider - This will run the provider with the -debug flag set to true.
2. Export the environment variable that the running provider logs out, it will look something like this:

TF_REATTACH_PROVIDERS='{"octopus.com/com/octopusdeploy":{"Protocol":"grpc","ProtocolVersion":5,"Pid":37485,"Test":true,"Addr":{"Network":"unix","String":"/var/folders/pq/_cv_xzg97ts8t2tq25d_43wr0000gn/T/plugin447612806"}}}'

3. In the same terminal session where you exported the environment variable, execute the Terraform commands you want to debug.

Via Delve

1. Add your breakpoints, this can be done by adding runtime.Breakpoint() lines to where you want the code to break.
2. Run dlv debug . -- --debug in the root folder of the project (same directory where main.go lives).
3. The debugger will start and wait, type continue in the terminal to get it to start the provider.
4. Export the environment variable that the running provider logs out, it will look something like this:

TF_REATTACH_PROVIDERS='{"octopus.com/com/octopusdeploy":{"Protocol":"grpc","ProtocolVersion":5,"Pid":37485,"Test":true,"Addr":{"Network":"unix","String":"/var/folders/pq/_cv_xzg97ts8t2tq25d_43wr0000gn/T/plugin447612806"}}}'

5. In the same terminal session where you exported the environment variable, execute the Terraform commands you want to debug.

Testing

The tests under integration_test.go verify the Terraform modules under the terraform directory run as expected. At a high level, the tests work like this:

• Create a new Octopus Deploy instance and MSSQL in Docker using Test Containers.
• Create a new blank space using the module in 1-singlespace.
• Populate the new space using one of the other modules under the terraform directory.
• Inspect the new space with the Octopus Go client to verify the newly created resources exist and have the expected settings.

These tests are split by go-test-split-action to run in parallel across multiple GitHub Action workers as part of the build.

To run the tests locally, you must have the following environment variables:

• LICENSE: base 64 encoded octopus license XML file
• ECR_ACCESS_KEY: aws access key (optional, and only used for ECR feed tests)
• ECR_SECRET_KEY: aws secret key (optional, and only used for ECR feed tests)
• GIT_CREDENTIAL: github token (optional, and only used for CaC tests)
• GIT_USERNAME: github username (optional, and only used for CaC tests)

By default, the tests spin up an Octopus instance based on the locally pulled octopusdeploy/octopusdeploy:latest image. You can override the image and tag with the following environment variables:

• OCTOTESTIMAGEURL: The image to use to create the Octopus instance. Defaults to octopusdeploy/octopusdeploy. Can be set to octopusdeploy/linuxoctopus to test the Octopus cloud builds. Note you must be logged into DockerHub with the correct credentials to pull this private image.
• OCTOTESTVERSION: The version of the image to use. Defaults to latest.

The tests can be run in parallel to speed up the test run time. Set the GOMAXPROCS environment variable to the number of parallel tests you want to run. For example, to run 4 tests in parallel, set GOMAXPROCS=4. Note though that each test creates it own Octopus and MSSQL docker images, so you will need to have enough resources to run the tests in parallel.

The tests work by executing the terraform executable against the test modules. By default, the version of the terraform provider that is used for these tests is defined in the file config.tf. The version defined in this file is almost always going to be a few revisions old.

To test the latest build of the Terraform provider, you must build the provider executable locally and define an override to configure Terraform to ignore the version of the provider defined in the module and instead use your local build.

Build the terraform provider with the command:

go build -o terraform-provider-octopusdeploy main.go

Then save the following configuration to a file called ~/.terraformrc, making sure to replace the string /var/home/yourname/Code/ with the path to the directory containing the Terraform provider executable:

provider_installation {
  dev_overrides {
    "octopusdeploylabs/octopusdeploy" = "/var/home/yourname/Code/terraform-provider-octopusdeploy"
  }

  direct {}
}

When the overrides are in effect, terraform will print a warning message to the console:

Warning: Provider development overrides are in effect
        
The following provider development overrides are set in the CLI
configuration:
 - octopusdeploylabs/octopusdeploy in /var/home/yourname/Code/terraform-provider-octopusdeploy

If you wish to view the Octopus instance created by the test framework, add a breakpoint after the call to testFramework.Act() and get the IP address and port from the container argument:

You can then log into the Octopus instance with the credentials admin and Password01!.
