Mirantis Launchpad provider

A terraform provider which integrates the Mirantis Launchpad tooling to natively install/remove the Mirantis container products as terraform resources.

Primarily, the provider provides resource types which will accept cluster and product configuration, which is used to configure launchpad to run. Launchpad executions are implemented using golang imports, not through shell commands, so no local environment constraints exist, other than terraform requirements.

This provider is developed internally, and comes with no warranty. Use it at your own risk.

Requirements

• Terraform >= 1.4
• Go >= 1.20
• GoReleaser : If you want to use it locally

Building The Provider

1. Clone the repository
2. Enter the repository directory
3. Build the provider using the make local command (uses goreleaser)

 $/> make local

Adding Dependencies

This provider uses Go modules. Please see the Go documentation for the most up to date information about using Go modules.

To add a new dependency github.com/author/dependency to your Terraform provider:

go get github.com/author/dependency
go mod tidy

Then commit the changes to go.mod and go.sum.

Using the provider

The provider, once installed properly can be used in any terraform root/chart.

Using the released provider

Go to the terraform registry page and follow the instructions for declaring the provider version in your chart/module

@see https://registry.terraform.io/providers/Mirantis/launchpad/latest

Using the local source code provider

The make local target will use goreleaser to build the provider, and then provide instructions on how to configure terraform to use the provider locally,

@see https://developer.hashicorp.com/terraform/cli/config/config-file#development-overrides-for-provider-developers

Developing the Provider

Using the local provider

You can develop the provider locally, and test the development version by building the plugin locally, and then configuring terraform to use the local version as a dev_override for the production version.

To build the local plugin:

make local

It is recommended that you use the dev_override by using a special TF config file and running terraform with an environment variable telling it to use the special file. This avoids using the development version globally, preventing simple mistakes.

First create a file like my_tf_config_file:

provider_installation {
# This disables the version and checksum verifications for this provider
# and forces Terraform to look for the launchpad provider plugin in the
# given directory.
dev_overrides {
	"mirantis/launchpad" = "path/to/this/repo/dist/terraform-provider-launchpad_linux_amd64_v1"
}
# For all other providers, install them directly from their origin provider
# registries as normal. If you omit this, Terraform will _only_ use
# the dev_overrides block, and so no other providers will be available.
direct {}
}

@NOTE that you mus replace linux and amd64 if you are on a Mac/Windows machine or not on a 64bit intel/amd processor. See go env GOOS and go env GOARCH for the correct values.

then run terraform with a config file override pointing to the new file:

 $/> TF_CLI_CONFIG_FILE=my_tf_config_file terraform plan

(or use an environment variable export)
