How to use custom themes on Keycloak Operator deployment on Kubernetes?

Question

I installed Keycloak using Operator (version 12.0.1). It's using the repository github repository Everything worked seamlessly. A keycloak instance has been launched and I could log in using admin credentials. I could see a realm, clients, users, etc working as expected.

But I do have a custom theme that I want to use it. For that, I make the following changes in my-realm.yaml.

apiVersion: keycloak.org/v1alpha1
kind: Keycloak
metadata:
  name: my-keycloak
  labels:
    app: my-keycloak
spec:
  instances: 1
  extensions:
    - https://github.com/aerogear/keycloak-metrics-spi/releases/download/1.0.4/keycloak-metrics-spi-1.0.4.jar
  externalAccess:
    enabled: False
  podDisruptionBudget:
    enabled: True
---
apiVersion: keycloak.org/v1alpha1
kind: KeycloakRealm
metadata:
  name: my-realm
  labels:
    app: my-realm
spec:
  realm:
    id: "my"
    realm: "my"
    enabled: True
    registrationEmailAsUsername: True
    accountTheme: "account-theme"       // THEMES
    adminTheme: "admin-theme"           // THEMES
    emailTheme: "email-theme"           // THEMES
    loginTheme: "login-theme"           // THEMES
    users:
      - username: "[email protected]"
        firstName: "Service"
        lastName: "Account"
  instanceSelector:
    matchLabels:
      app: my-keycloak

But, I didn't see any of the themes in my realms/my-realm/theme-settings. I can see only the default theme in the select box (i.e. keycloak, base). I am expecting account-theme, admin-theme, email-theme, login-theme in their respective select boxes.

Am I missing something here?

The problem is/was that -- until yesterday the 26th of January of 2021, commit f2d0370290d6abe91724b2536748aa6b1245d1e1 (pull request #284) -- by default the Keycloak Operator did not recognize the Theme-related fields (i.e., accountTheme, adminTheme, emailTheme, loginTheme).

This feature was not deployed on the current latest release (12.0.2), however it is available of master. So you can go from there.
