Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Now, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Keycloak admin console becomes inaccessible after changing the theme

Due to the upstream Keycloack issue, the Keycloak admin console becomes inaccessible after changing the theme to base using the Themes tab.

To apply the issue resolution:

1. Obtain the MySQL admin password:

   kubectl get secret -n kaas mariadb-dbadmin-password -o yaml | awk '/MYSQL_DBADMIN_PASSWORD/ {print $2}' | base64 -d
   

2. Connect to the MariaDB server:

   kubectl exec -it -n kaas mariadb-server-0 -- mysql -h localhost -u root -p
   

3. Update the Keycloak database for the following themes:

   • ADMIN_THEME

   • ACCOUNT_THEME

   • EMAIL_THEME

   • LOGIN_THEME

   For example:

   use keycloak;
   update REALM set ADMIN_THEME = REPLACE(ADMIN_THEME, 'base','keycloak');
   

4. Restart Keycloak:

   kubectl scale sts -n kaas --replicas=0 iam-keycloak
   kubectl scale sts -n kaas --replicas=3 iam-keycloak
