Operator 4.1.1

Major Changes

• The init container that sets the initial directory permissions prior to creating a domain on persistent volume will now default to running as a non-root user.
  • Operator 4.1.0 added the ability to create a persistent volume (PV) and persistent volume claim (PVC) and then create the WebLogic domain home based on the provided WDT models.
  • In the initial release of this feature, the init container would run as root. This has been changed and this container now runs as the same user, "oracle" (uid: 1000), that is used for the introspection and WebLogic Server instance containers.
  • Customers can restore the original behavior with the new Domain resource field initializeDomainOnPV.runDomainInitContainerAsRoot.
• The serverPod field of the Domain and Cluster resources now supports standard envFrom content, allowing WebLogic Server instance containers to define environment variables that are sourced from a config map or secret. Variables that are defined in the values of these environment variables will not be replaced as they are for environment variables defined explicitly with env; however, any variables in the JAVA_OPTIONS environment variable will be replaced if the spec.replaceVariablesInJavaOptions field is set to true.

Other Changes

• Dependency updates for Okio and Bouncy Castle

Bug Fixes

• Liveness probe for WebLogic Server instance containers is hardened to fail whenever the server process is missing.

Full Changelog: v3.4.7...v3.4.8

Operator 4.1.0

Deprecation Notices

• Model in Image without auxiliary images (the WDT model and installation files are included in the same image with the WebLogic Server installation) is deprecated in WebLogic Kubernetes Operator version 4.0.7. Oracle recommends that you use Model in Image with auxiliary images.

Additional Features

• Support for the automated creation of domains on persisted volumes where the initial domain topology and resources are described using WebLogic Deploy Tooling (WDT) models.

Bug Fixes

• All bug fixes included in the 4.0.7 release are also included in this release.

Operator 4.0.7

Deprecation Notices

• Model in Image without auxiliary images (the WDT model and installation files are included in the same image with the WebLogic Server installation) is deprecated in WebLogic Kubernetes Operator version 4.0.7. Oracle recommends that you use Model in Image with auxiliary images.

Other Changes

• The Helm chart now supports the jvmOptions value that specifies the Java options used to run the operator process and the default value includes a reasonable value for -XXMaxRAMPercentage.
• The default WebLogic Monitoring Exporter version is now 2.1.4.

Bug Fixes

• Removed Helm chart usage of built-in Kubernetes roles system:auth-delegator and system:discovery.
• Corrected Helm chart generation of javaLoggingFileSizeLimit.
• Corrected domain and cluster CRD generation of quantity-typed fields, such as emptyDir.sizeLimit.
• Samples now generate valid cluster resources when the WebLogic cluster name includes characters that are not permitted in resource names.
• The operator now correctly deletes external services when no longer required.
• The introspection job generated by the operator is no longer excluded from the Istio Mesh.
• When the operator cannot validate the contents of the domain and cluster CRDs, such as in dedicated mode use cases where the operator does not have cluster-level privileges, the number of warning messages in the operator's log is limited.

Full Changelog: v4.0.6...v4.0.7

Operator 4.0.6

• Resolved several issues related to delayed watch notifications:
  • Resolved an issue where an introspection Failed domain status message is generated.
  • Resolved an issue where a DOMAIN_CHANGED event was not generated.
  • Resolved an issue where a Cluster was marked as Failed.
• Resolved an issue where the WDT model has a Server named "adminserver", but does not explicitly specify that this server is the Administration Server using the AdminServerName.
• Update the SnakeYAML dependency to version 2.0.
• Added support for new zip structure in WDT archive for database wallets.
• Container image is now multi-platform, including support for AMD64 and ARM64.
• Resolved an issue where the operator would generate invalid URLs for WebLogic Server instances if the namespace name started with a numeric character.
• Resolved an upgrade issue related to security contexts on init containers.
• Resolved an issue related to seccompProfile security context entry on OpenShift.

Operator 3.4.7

• Resolved an issue related to WDT models that do not contain AdminServerName.
• Updated usage of the SnakeYAML SafeConstructor to avoid usage of the empty-arguments constructor.

Operator 4.0.5

• Updated the Fluentd integration to make the Elasticsearch credentials optional and to allow the specification of the container command and arguments.
• Resolved an issue related to growth in the number of WebLogic sessions related to the monitoring exporter and health checks.
• Resolved issue #3865 related to decorating the name of the ConfigMap for Fluentd integration (#3883).
• Updated the generation of pods and containers for security best practices.
• Added support to specify the container resources and Java options for the introspector job.
• Changed the Helm chart to disable the operator's REST endpoint by default. This endpoint is only needed for WLDF action based scaling. All other forms of scaling are unaffected by this change.
• Resolved an issue related to schema webhook conversion of the domainHomeInImage field.
• Resolved an issue related to schema webhook conversion of status conditions only supported for "v9" schema.
• Resolved an issue related to the ordering of init containers generated for "v8" style auxiliary images.
