terraform-provider-keycloak

Terraform provider for Keycloak.

Note

Please note that this is currently work-in-progress, please be patient while we are preparing for the first release in the new organization.

Migration to the new provider

To migrate from mrparkers/keycloak to the keycloak/keycloak Terraform provider, you can use the terraform state replace-provider command:

terraform state replace-provider mrparkers/keycloak keycloak/keycloak

You can find the documentation for this command here.

Docs

All documentation for this provider can now be found on the Terraform Registry: https://registry.terraform.io/providers/keycloak/keycloak/latest/docs

Installation

This provider can be installed automatically using Terraform >=0.13 by using the terraform configuration block:

terraform {
  required_providers {
    keycloak = {
      source = "keycloak/keycloak"
      version = ">= 4.0.0"
    }
  }
}

If you are using Terraform 0.12, you can use this provider by downloading it and placing it within one of the implied local mirror directories. Or, follow the old instructions for installing third-party plugins.

If you are using any provider version below v2.0.0, you can also follow the old instructions for installing third-party plugins.

A note for users of the legacy Wildfly distribution

Recently, Keycloak has been updated to use Quarkus over the legacy Wildfly distribution. The only significant change here that affects this Terraform provider is the removal of /auth from the default context path for the Keycloak API.

If you are using the legacy Wildfly distribution of Keycloak, you will need to set the base_path provider argument to /auth. This can also be done by using the KEYCLOAK_BASE_PATH environment variable.

Supported Versions

This provider will officially support the latest three major versions of Keycloak, although older versions may still work.

The following versions are used when running acceptance tests in CI:

  • 21.0.1 (latest)
  • 20.0.5
  • 19.0.2

Releases

This provider uses GoReleaser to build and publish releases. Each release published to GitHub contains binary files for Linux, macOS (darwin), and Windows, as configured within the .goreleaser.yml file.

Each release also contains a terraform-provider-keycloak_${RELEASE_VERSION}_SHA256SUMS file, accompanied by a signature created by a PGP key with the fingerprint C508 6791 5E11 6CD2. This key can be found on my Keybase account at https://keybase.io/mrparkers.

You can find the list of releases here. You can find the changelog for each version here.

Note: Prior to v2.0.0, a statically linked build for use within Alpine linux was included with each release. This is no longer done due to GoReleaser not supporting CGO. Instead of using a statically linked, build you can use the linux_amd64 build as long as libc6-compat is installed.

Development

This project requires Go 1.19 and Terraform 1.4.1. This project uses Go Modules for dependency management, which allows this project to exist outside of an existing GOPATH.

After cloning the repository, you can build the project by running make build.

Local Environment

You can spin up a local developer environment via Docker Compose by running make local. This will spin up a few containers for Keycloak, PostgreSQL, and OpenLDAP, which can be used for testing the provider. This environment and its setup via make local is not intended for production use.

Note: The setup scripts require the jq command line utility.

Tests

Every resource supported by this provider will have a reasonable amount of acceptance test coverage.

You can run acceptance tests against a Keycloak instance by running make testacc. You will need to supply some environment variables in order to set up the provider during tests. Here is an example for running tests against a local environment that was created via make local:

KEYCLOAK_CLIENT_ID=terraform \
KEYCLOAK_CLIENT_SECRET=884e0f95-0f42-4a63-9b1f-94274655669e \
KEYCLOAK_CLIENT_TIMEOUT=5 \
KEYCLOAK_REALM=master \
KEYCLOAK_URL="http://localhost:8080" \
make testacc
