  • Now you can update application Fluentd sidecar images following a Verrazzano update.
  • Documented Verrazzano specific OAM workload resources.
  • Documented Verrazzano hardware requirements and installed software versions.


  • VerrazzanoWebLogicWorkload and VerrazzanoCoherenceWorkload resources now handle updates.
  • Now VerrazzanoHelidonWorkload supports the use of the ManualScalarTrait.
  • Now you can delete a Namespace containing an ApplicationConfiguration resource.
  • Fixed frequent restarts of Prometheus during application deployment.
  • Made verrazzano-application-operator logging more useful and use structured logging.
  • Fixed Verrazzano uninstall issues.



  • Observability stack now uses Keycloak SSO for authentication.
  • Istio sidecars now automatically injected when namespaces labeled istio-injection=enabled.
  • Support for Helidon applications now defined using VerrazzanoHelidonWorkload type.


  • Fixed issues where logs were not captured from all containers in workloads with multiple containers.
  • Fixed issue where some resources were not cleaned up during uninstall.

  • Incremental improvements to user-facing roles.


  • Fixed issue with logging when an application has multiple workload types.

Breaking Changes:

  • Model/binding files removed; now application deployment done exclusively by using Open Application Model (OAM).
  • Syntax changes for WebLogic and Coherence OAM workloads, now defined using VerrazzanoCoherenceWorkload and VerrazzanoWebLogicWorkload types.


  • By default, application endpoints now use HTTPs - when using magic DNS, certificates are issued by cluster issuer, when using OCI DNS certificates are issued using Let’s Encrypt, or the end user can provide certificates.
  • Updated Coherence operator to 3.1.3.
  • Updates for running Verrazzano on Kubernetes 1.19 and 1.20.
  • RBAC roles and role bindings created at install time.
  • Added instance information to status of Verrazzano custom resource; can be used to obtain instance URLs.
  • Upgraded Istio to v1.7.3.


  • Reduced log level of Elasticsearch; excessive logging could have resulted in filling up disks.


  • Features:
    • Added platform support for installing Verrazzano on Kind clusters.
    • Log records are indexed from the OAM appconfig and component definitions using the following pattern: namespace-appconfig-component.
    • All system and curated components are now patchable.
    • More updates to Open Application Model (OAM) support.

To enable OAM, when you install Verrazzano, specify the following in the Kubernetes manifest file for the Verrazzano custom resource:

    enabled: true


  • Features:
    • Support for two installation profiles, development (dev) and production (prod). The production profile, which is the default, provides a 3-node Elasticsearch and persistent storage for the Verrazzano Monitoring Instance (VMI). The development profile provides a single node Elasticsearch and no persistent storage for the VMI.
    • The default behavior has been changed to use the system VMI for all monitoring (applications and Verrazzano components). It is still possible to customize one of the profiles to enable the original, non-shared VMI mode.
    • Initial support for the Open Application Model (OAM).
  • Fixes:
    • Updated Axios NPM package to v0.21.1 to resolve a security vulnerability in the examples code.


  • Features:

    • Ability to upgrade an existing Verrazzano installation.
    • Added the Verrazzano Console.
    • Enhanced the structure of the Verrazzano custom resource to allow more configurability.
    • Streamlined the secret usage for OCI DNS installations.
  • Fixes:

    • Fixed bug where the Verrazzano CR Certificate.CA fields were being ignored.
    • Removed secret used for hello-world; hello-world-application image is now public in ghcr so ImagePullSecrets is no longer needed.
    • Fixed issue #339 (PRs #208 & #210.)


  • Features:
    • In-cluster installer which replaces client-side install scripts.
    • Added installation profiles; in this release, there are two: production and development.
    • Verrazzano system components now emit JSON structured logs.
  • Fixes:
    • Updated Elasticsearch and Kibana versions (elasticsearch:7.6.1-20201130145440-5c76ab1) and (kibana:7.6.1-20201130145840-7717e73).
