Overview

The keycloak module allows easy installation and management of Keycloak.

Supported Versions of Keycloak

Currently this module supports Keycloak version 12.x. This module may work on earlier versions but this is the only version tested.

Keycloak Version Keycloak Puppet module versions
3.x 2.x
4.x - 6.x 3.x
6.x - 8.x 4.x - 5.x
8.x - 12.x 6.x
12.x - 15.x 7.x

Usage

keycloak

Install Keycloak using default h2 database storage.

class { 'keycloak': }

Install a specific version of Keycloak.

class { 'keycloak':
  version           => '6.0.1',
  datasource_driver => 'mysql',
}

Upgrading Keycloak version works by changing version parameter as long as the datasource_driver is not the default of h2. An upgrade involves installing the new version without touching the old version, updating the symlink which defaults to /opt/keycloak, applying all changes to new version and then restarting the keycloak service.

If the previous version was 6.0.1 using the following will upgrade to 7.0.0:

class { 'keycloak':
  version           => '7.0.0',
  datasource_driver => 'mysql',
}

Install keycloak and use a local MySQL server for database storage

include mysql::server
class { 'keycloak':
  datasource_driver   => 'mysql',
  datasource_host     => 'localhost',
  datasource_port     => 3306,
  datasource_dbname   => 'keycloak',
  datasource_username => 'keycloak',
  datasource_password => 'foobar',
}

The following example can be used to configure keycloak with a local PostgreSQL server.

include postgresql::server
class { 'keycloak':
    datasource_driver     => 'postgresql',
    datasource_host       => 'localhost',
    datasource_port       => 5432,
    datasource_dbname     => 'keycloak',
    datasource_username   => 'keycloak',
    datasource_password   => 'foobar',
}

Configure keycloak to use a remote Oracle database.

The parameter datasource_jar_source is always required with Oracle database. The jar is downloaded to the keycloak module dir and renamed to datasource_jar_filename or 'ojdbc8.jar' as default value.

With a special database configuration it may be more suitable to give the complete database url 'jdbc:oracle:thin:@[...]' using the parameter database_url instead of database_host, database_port and database_dbname. The default value with Oracle database for database_host is 'localhost' and the default value for database_port is here 1521.

class { 'keycloak':
    datasource_driver       => 'oracle',
    datasource_host         => 'oracleserver.mydomain.de',
    datasource_port         => 1521,
    datasource_dbname       => 'keycloak',
    datasource_username     => 'keycloak',
    datasource_password     => 'foobar',
    datasource_jar_source   => 'https://oracle.com/path/to/driver.jar',
    datasource_jar_filename => 'ojdbc8.jar',
}

Configure a SSL certificate truststore and add a LDAP server's certificate to the truststore.

class { 'keycloak':
  truststore                              => true,
  truststore_password                     => 'supersecret',
  truststore_hostname_verification_policy => 'STRICT',
}
keycloak::truststore::host { 'ldap1.example.com':
  certificate => '/etc/openldap/certs/0a00000.0',
}

Setup Keycloak to proxy through Apache HTTPS.

class { 'keycloak':
  proxy_https => true
}
apache::vhost { 'idp.example.com':
  servername => 'idp.example.com',
  port        => '443',
  ssl         => true,
  manage_docroot  => false,
  docroot         => '/var/www/html',
  proxy_preserve_host => true,
  proxy_pass          => [
    {'path' => '/', 'url' => 'http://localhost:8080/'}
  ],
  request_headers     => [
    'set X-Forwarded-Proto "https"',
    'set X-Forwarded-Port "443"'
  ],
  ssl_cert            => '/etc/pki/tls/certs/idp.example.com/crt',
  ssl_key             => '/etc/pki/tls/private/idp.example.com.key',
}

Setup a domain master. (This needs a shared database, here '1.2.3.4').

class { '::keycloak':
  operating_mode        => 'domain',
  role                  => 'master',
  wildfly_user          => 'wildfly,
  wildfly_user_password => 'changeme,
  manage_datasource     => false,
  datasource_driver     => 'postgresql',
  datasource_host       => '1.2.3.4,
  datasource_dbname     => 'keycloak,
  datasource_username   => 'keycloak,
  datasource_password   => 'changeme,
  admin_user            => 'admin,
  admin_user_password   => 'changeme,
}

Setup a domain slave. (This needs a shared database, here '1.2.3.4').

class { '::keycloak':
  operating_mode        => 'domain',
  role                  => 'slave',
  wildfly_user          => 'wildfly,
  wildfly_user_password => 'changeme,
  manage_datasource     => false,
  datasource_driver     => 'postgresql',
  datasource_host       => '1.2.3.4,
  datasource_dbname     => 'keycloak,
  datasource_username   => 'keycloak,
  datasource_password   => 'changeme,
  admin_user            => 'admin,
  admin_user_password   => 'changeme,
}

NOTE: The wilfdly user and password need to match those in domain master. These are required for authentication in a cluster.

Setup a host for theme development so that theme changes don't require a service restart, not recommended for production.

class { 'keycloak':
  theme_static_max_age  => -1,
  theme_cache_themes    => false,
  theme_cache_templates => false,
}

Run Keycloak using standalone clustered mode (multicast):

class { 'keycloak':
  operating_mode => 'clustered',
}

Run Keycloak using standalone clustered mode (JDBC_PING):

JDBC_PING uses port 7600 to ensure cluster members are discoverable by each other. This module does NOT manage firewall changes.

class { 'keycloak':
  operating_mode             => 'clustered',
  datasource_driver          => 'postgresql',
  enable_jdbc_ping           => true,
  jboss_bind_private_address => $facts['networking']['ip'],
  jboss_bind_public_address  => $facts['networking']['ip'],
}

# your puppet code to open port 7600
# ...
# ...

Deploy SPI

A simple example of deploying a custom SPI from a URL:

keycloak::spi_deployment { 'duo-spi':
  ensure        => 'present',
  deployed_name => 'keycloak-duo-spi-jar-with-dependencies.jar',
  source        => 'https://example.com/files/keycloak-duo-spi-jar-with-dependencies.jar',
}

The source can be a URL or a file path like /tmp/foo.jar or prefixed with file:// or puppet://

The following example will deploy a custom SPI then check the Keycloak API for the resource to exist. This is useful to ensure SPI is loaded into Keycloak before attempting to add custom resources.

keycloak::spi_deployment { 'duo-spi':
  deployed_name => 'keycloak-duo-spi-jar-with-dependencies.jar',
  source        => 'https://example.com/files/keycloak-duo-spi-jar-with-dependencies.jar',
  test_url      => 'authentication/authenticator-providers',
  test_key      => 'id',
  test_value    => 'duo-mfa-authenticator',
  test_realm    => 'test',
  test_before   => [
    'Keycloak_flow[form-browser-with-duo]',
    'Keycloak_flow_execution[duo-mfa-authenticator under form-browser-with-duo on test]',
  ],
}

keycloak_realm

Define a Keycloak realm that uses username and not email for login and to use a local branded theme.

keycloak_realm { 'test':
  ensure                   => 'present',
  remember_me              => true,
  login_with_email_allowed => false,
  login_theme              => 'my_theme',
}

NOTE: If the flow properties such as browser_flow are changed from their defaults then this value will not be set when a realm is first created. The value will also not be updated if the flow does not exist. For new realms you will have to run Puppet twice in order to create the flows then update the realm setting.

keycloak_role_mapping

Manage realm role mappings for users and groups. Example:

keycloak_role_mapping { 'roles for john on master':
  realm       => 'master',
  name        => 'john',
  realm_roles => ['role1', 'role2'],
}

keycloak_role_mapping { 'roles for mygroup on master':
  realm        => 'master',
  name         => 'mygroup',
  group        => true,
  realm_roles  => ['role1'],
}

keycloak_ldap_user_provider

Define a LDAP user provider so that authentication can be performed against LDAP. The example below uses two LDAP servers, disables importing of users and assumes the SSL certificates are trusted and do not require being in the truststore.

keycloak_ldap_user_provider { 'LDAP on test':
 ensure             => 'present',
 users_dn           => 'ou=People,dc=example,dc=com',
 connection_url     => 'ldaps://ldap1.example.com:636 ldaps://ldap2.example.com:636',
 import_enabled     => false,
 use_truststore_spi => 'never',
}

NOTE The Id for the above resource would be LDAP-test where the format is ${resource_name}-${realm}.

If you're using FreeIPA you can use a defined resource that wraps keycloak_ldap_user_provider:

keycloak::freeipa_user_provider { 'ipa.example.org':
  ensure          => 'present',
  realm           => 'EXAMPLE.ORG',
  bind_dn         => 'uid=ldapproxy,cn=sysaccounts,cn=etc,dc=example,dc=org',
  bind_credential => 'secret',
  users_dn        => 'cn=users,cn=accounts,dc=example,dc=org',
  priority        => 10,
}

keycloak_ldap_mapper

Use the LDAP attribute 'gecos' as the full name attribute.

keycloak_ldap_mapper { 'full name for LDAP-test on test:
  ensure         => 'present',
  resource_name  => 'full name',
  type           => 'full-name-ldap-mapper',
  ldap_attribute => 'gecos',
}

If you're using FreeIPA you can use a defined resource that adds all the required attribute mappings automatically:

keycloak::freeipa_ldap_mappers { 'ipa.example.org':
  realm            => 'EXAMPLE.ORG',
  groups_dn        => 'cn=groups,cn=accounts,dc=example,dc=org',
  roles_dn         => 'cn=groups,cn=accounts,dc=example,dc=org'
}

keycloak_sssd_user_provider

Define SSSD user provider. NOTE This type requires that SSSD be properly configured and Keycloak service restarted after SSSD ifp service is setup. Also requires keycloak class be called with with_sssd_support set to true.

keycloak_sssd_user_provider { 'SSSD on test':
  ensure => 'present',
}

keycloak_client

Register a client.

keycloak_client { 'www.example.com':
  ensure          => 'present',
  realm           => 'test',
  redirect_uris   => [
    "https://www.example.com/oidc",
    "https://www.example.com",
  ],
  client_template => 'oidc-clients',
  secret          => 'supersecret',
}

keycloak::client_scope::oidc

Defined type that can be used to define both keycloak_client_scope and keycloak_protocol_mapper resources for OpenID Connect. 

keycloak::client_scope::oidc { 'oidc-clients':
  realm => 'test',
}

keycloak::client_scope::saml

Defined type that can be used to define both keycloak_client_scope and keycloak_protocol_mapper resources for SAML. 

keycloak::client_scope::saml { 'saml-clients':
  realm => 'test',
}

keycloak_client_scope

Define a Client Scope of email for realm test in Keycloak:

keycloak_client_scope { 'email on test':
  protocol => 'openid-connect',
}

keycloak_protocol_mapper

Associate a Protocol Mapper to a given Client Scope. The name in the following example will add the email protocol mapper to client scope oidc-email in the realm test.

keycloak_protocol_mapper { "email for oidc-email on test":
  claim_name     => 'email',
  user_attribute => 'email',
}

keycloak_client_protocol_mapper

Add email protocol mapper to test.example.com client in realm test

keycloak_client_protocol_mapper { "email for test.example.com on test":
  claim_name     => 'email',
  user_attribute => 'email',
}

keycloak_identity_provider

Add cilogon identity provider to test realm

keycloak_identity_provider { 'cilogon on test':
  ensure                        => 'present',
  display_name                  => 'CILogon',
  provider_id                   => 'oidc',
  first_broker_login_flow_alias => 'browser',
  client_id                     => 'cilogon:/client_id/foobar',
  client_secret                 => 'supersecret',
  user_info_url                 => 'https://cilogon.org/oauth2/userinfo',
  token_url                     => 'https://cilogon.org/oauth2/token',
  authorization_url             => 'https://cilogon.org/authorize',
}

Keycloak Flows

The following is an example of deploying a custom Flow. The name for the top level flow is $alias on $realm The name for an execution is $provider under $flow on $realm. The name for the flow under a top level flow is $alias under $flow_alias on $realm.

keycloak_flow { 'browser-with-duo on test':
  ensure => 'present',
}
keycloak_flow_execution { 'auth-cookie under browser-with-duo on test':
  ensure       => 'present',
  configurable => false,
  display_name => 'Cookie',
  index        => 0,
  requirement  => 'ALTERNATIVE',
}
keycloak_flow_execution { 'identity-provider-redirector under browser-with-duo on test':
  ensure       => 'present',
  configurable => true,
  display_name => 'Identity Provider Redirector',
  index        => 1,
  requirement  => 'ALTERNATIVE',
}
keycloak_flow { 'form-browser-with-duo under browser-with-duo on test':
  ensure      => 'present',
  index       => 2,
  requirement => 'ALTERNATIVE',
  top_level   => false,
}
keycloak_flow_execution { 'auth-username-password-form under form-browser-with-duo on test':
  ensure       => 'present',
  configurable => false,
  display_name => 'Username Password Form',
  index        => 0,
  requirement  => 'REQUIRED',
}
keycloak_flow_execution { 'duo-mfa-authenticator under form-browser-with-duo on test':
  ensure       => 'present',
  configurable => true,
  display_name => 'Duo MFA',
  alias        => 'Duo',
  config       => {
    "duomfa.akey"    => "foo-akey",
    "duomfa.apihost" => "api-foo.duosecurity.com",
    "duomfa.skey"    => "secret",
    "duomfa.ikey"    => "foo-ikey",
    "duomfa.groups"  => "duo"
  },
  requirement  => 'REQUIRED',
  index        => 1,
}

keycloak_api

The keycloak_api type can be used to define how this module's types access the Keycloak API if this module is only used for the types/providers and the module's kcadm-wrapper.sh is not installed.

keycloak_api { 'keycloak'
 install_dir => '/opt/keycloak',
 server     => 'http://localhost:8080/auth',
 realm      => 'master',
 user       => 'admin',
 password   => 'changeme',
}

The path for install_dir will be joined with bin/kcadm.sh to produce the full path to kcadm.sh.

keycloak_required_action

The keycloak_required_action type can be used to define actions a user must perform during the authentication process. A user will not be able to complete the authentication process until these actions are complete. For instance, change a one-time password, accept T&C, etc.

The name for an action is $alias on $realm.

Important: actions from puppet config and from a server are matched based on a combination of alias and realm, so edition of aliases is not supported.

# Minimal example
keycloak_required_action { 'VERIFY_EMAIL on master':
 ensure => present,
 provider_id => 'webauthn-register',
}

# Full example

keycloak_required_action { 'webauthn-register on master':
 ensure => present,
 provider_id => 'webauthn-register',
 display_name => 'Webauthn Register',
 default => true,
 enabled => true,
 priority => 1,
 config => {
   'something' => 'true', # keep in mind that keycloak only supports strings for both keys and values
   'smth else' => '1',
 },
}
