|
|
|
|
Keycloak supports a file-based vault implementation for Kubernetes/OpenShift secrets. Mount Kubernetes secrets into the Keycloak Container, and the data fields will be available in the mounted folder with a flat-file structure.
|
|
|
|
== Available integrations
|
|
You can use Kubernetes/OpenShift secrets for the following purposes:
|
|
|
|
* Obtain the SMTP Mail server Password
|
|
* Obtain the LDAP Bind Credential when using LDAP-based User Federation
|
|
* Obtain the OIDC identity providers Client Secret when integrating external identity providers
|
|
|
|
== Enabling the vault
|
|
Enable the file based vault by building Keycloak using the following build option:
|
|
|
|
<@kc.build parameters="--vault=file"/>
|
|
|
|
== Setting the base directory to lookup secrets
|
|
Kubernetes/OpenShift secrets are basically mounted files. To configure a directory where these files should be mounted, enter this command:
|
|
|
|
<@kc.start parameters="--vault-dir=/my/path"/>
|
|
|
|
== Realm-specific secret files
|
|
Kubernetes/OpenShift Secrets are used on a per-realm basis in Keycloak, which requires a naming convention for the file in place:
|
|
[source, bash]
|
|
----
|
|
${r"${vault.<realmname>_<secretname>}"}
|
|
----
|
|
|
|
=== Using underscores in the Name
|
|
To process the secret correctly, you double all underscores in the <realmname> or the <secretname>, separated by a single underscore.
|
|
|
|
.Example
|
|
* Realm Name: `sso_realm`
|
|
* Desired Name: `ldap_credential`
|
|
* Resulting file Name:
|
|
[source, bash]
|
|
----
|
|
sso__realm_ldap__credential
|
|
----
|
|
Note the doubled underscores between __sso__ and __realm__ and also between __ldap__ and __credential__.
|
|
|
|
== Example: Use an LDAP bind credential secret in the Admin Console
|
|
|
|
.Example setup
|
|
* A realm named `secrettest`
|
|
* A desired Name `ldapBc` for the bind Credential
|
|
* Resulting file name: `secrettest_ldapBc`
|
|
|
|
.Usage in Admin Console
|
|
You can then use this secret from the Admin Console by using `${r"${vault.ldapBc}"}` as the value for the `Bind Credential` when configuring your LDAP User federation.
