> NOTE: You can configure the `scopes` parameter to restrict the OpenID scopes requested by minio to the IdP, for example, `"openid,policy_role_attribute"`, being `policy_role_attribute` a client_scope / client_mapper that maps a role attribute called policy to a `policy` claim returned by Keycloak

Once successfully set restart the MinIO instance.

mc admin service restart myminio

## Platform architecture

Gradle is arranged into several coarse-grained components called "platforms".
Each platform provides support for some kind of automation, such as building JVM software or building Gradle plugins.
Most platforms typically build on the features of other platforms.

     *  Evaluate XPath string to an XObject.
     *  XPath namespace prefixes are resolved from the namespaceNode.
     *  The implementation of this is a little slow, since it creates
     *  a number of objects each time it is called.  This could be optimized
     *  to keep the same objects around, but then thread-safety issues would arise.
     *
     *  @param contextNode The node to start searching from.
     *  @param expression A valid XPath string.

// K8S may get a pod Add event without any IPs in the object, and the pod will later be updated with IPs.
//
// We always need the IPs, but this is fine because this AddPodToMesh can be called from the CNI plugin as well,
// which always has the firsthand info of the IPs, even before K8S does - so we pass them separately here because
// we actually may have them before K8S in the Pod object.
