Keycloak Provider

Installation

The keycloak provider is available as a package in all Pulumi languages:

• JavaScript/TypeScript: @pulumi/keycloak
• Python: pulumi-keycloak
• Go: github.com/pulumi/pulumi-keycloak/sdk/v5/go/keycloak
• .NET: Pulumi.Keycloak
• Java: com.pulumi/keycloak

Overview

The Keycloak provider can be used to interact with Keycloak.

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 Pulumi 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 basePath provider argument to /auth. This can also be done by using the KEYCLOAK_BASE_PATH environment variable.

Keycloak Setup

This Pulumi provider can be configured to use the client credentials or password grant types. If you aren’t sure which to use, the client credentials grant is recommended, as it was designed for machine to machine authentication.

Client Credentials Grant Setup (recommended)

1. Create a new client using the openid-connect protocol. This client can be created in the master realm if you would like to manage your entire Keycloak instance, or in any other realm if you only want to manage that realm.
2. Update the client you just created:
   1. Set Access Type to confidential.
   2. Set Standard Flow Enabled to OFF.
   3. Set Direct Access Grants Enabled to OFF
   4. Set Service Accounts Enabled to ON.
3. Grant required roles for managing Keycloak via the Service Account Roles tab in the client you created in step 1, see Assigning Roles section below.

Password Grant Setup

These steps will assume that you are using the admin-cli client, which is already correctly configured for this type of authentication. Do not follow these steps if you have already followed the steps for the client credentials grant.

1. Create or identify the user whose credentials will be used for authentication.
2. Edit this user in the “Users” section of the management console and assign roles using the “Role Mappings” tab.

Assigning Roles

There are many ways that roles can be assigned to manage Keycloak. Here are a couple of common scenarios accompanied by suggested roles to assign. This is not an exhaustive list, and there is often more than one way to assign a particular set of permissions.

• Managing the entire Keycloak instance: Assign the admin role to a user or service account within the master realm.
• Managing the entire foo realm: Assign the realm-admin client role from the realm-management client to a user or service account within the foo realm.
• Managing clients for all realms within the entire Keycloak instance: Assign the create-client client role from each of the realm clients to a user or service account within the master realm. For example, given a Keycloak instance with realms master, foo, and bar, assign the create-client client role from the clients master-realm, foo-realm, and bar-realm.

Configuration Reference

The following configuration inputs are supported:

• clientId - (Required) The clientId for the client that was created in the “Keycloak Setup” section. Use the admin-cli client if you are using the password grant. Defaults to the environment variable KEYCLOAK_CLIENT_ID.
• url - (Required) The URL of the Keycloak instance, before /auth/admin. Defaults to the environment variable KEYCLOAK_URL.
• clientSecret - (Optional) The secret for the client used by the provider for authentication via the client credentials grant. This can be found or changed using the “Credentials” tab in the client settings. Defaults to the environment variable KEYCLOAK_CLIENT_SECRET. This attribute is required when using the client credentials grant, and cannot be set when using the password grant.
• username - (Optional) The username of the user used by the provider for authentication via the password grant. Defaults to the environment variable KEYCLOAK_USER. This attribute is required when using the password grant, and cannot be set when using the client credentials grant.
• password - (Optional) The password of the user used by the provider for authentication via the password grant. Defaults to the environment variable KEYCLOAK_PASSWORD. This attribute is required when using the password grant, and cannot be set when using the client credentials grant.
• realm - (Optional) The realm used by the provider for authentication. Defaults to the environment variable KEYCLOAK_REALM, or master if the environment variable is not specified.
• initialLogin - (Optional) Optionally avoid Keycloak login during provider setup, for when Keycloak itself is being provisioned by pulumi. Defaults to true, which is the original method.
• clientTimeout - (Optional) Sets the timeout of the client when addressing Keycloak, in seconds. Defaults to the environment variable KEYCLOAK_CLIENT_TIMEOUT, or 5 if the environment variable is not specified.
• tlsInsecureSkipVerify - (Optional) Allows ignoring insecure certificates when set to true. Defaults to false. Disabling this security check is dangerous and should only be done in local or test environments.
• rootCaCertificate - (Optional) Allows x509 calls using an unknown CA certificate (for development purposes)
• basePath - (Optional) The base path used for accessing the Keycloak REST API. Defaults to the environment variable KEYCLOAK_BASE_PATH, or an empty string if the environment variable is not specified. Note that users of the legacy distribution of Keycloak will need to set this attribute to /auth.
• additionalHeaders - (Optional) A map of custom HTTP headers to add to each request to the Keycloak API.
