The WebLogic Kubernetes Operator (the “operator”) supports running your WebLogic Server and Fusion Middleware Infrastructure domains on Kubernetes, an industry standard, cloud neutral deployment platform. It lets you encapsulate your entire WebLogic Server installation and layered applications into a portable set of cloud neutral images and simple resource description files. You can run them on any on-premises or public cloud that supports Kubernetes where you’ve deployed the operator.
Furthermore, the operator is well suited to CI/CD processes. You can easily inject changes when moving between environments, such as from test to production. For example, you can externally inject database URLs and credentials during deployment or you can inject arbitrary changes to most WebLogic configurations.
The operator takes advantage of the Kubernetes operator pattern, which means that it uses Kubernetes APIs to provide support for operations, such as: provisioning, lifecycle management, application versioning, product patching, scaling, and security. The operator also enables the use of tooling that is native to this infrastructure for monitoring, logging, tracing, and security.
The fastest way to experience the operator is to follow the Quick Start guide, or you can peruse our documentation, read our blogs, or try out the samples. Also, you can step through the Tutorial using the operator to deploy and run a WebLogic domain container-packaged web application on an Oracle Container Engine for Kubernetes (OKE) cluster.
The current release of the operator is 4.0.5. This release was published on February 21, 2023. See the operator prerequisites and supported environments.
See the Release Notes for recent changes to the operator and known issues.
Documentation for prior releases of the operator: 2.5.0, 2.6.0, 3.0.x, 3.1.x, 3.2.x, 3.3.x, and 3.4.x.
Starting from the 2.0.1 release, operator releases are backward compatible with respect to the domain resource schema, operator Helm chart input values, configuration overrides template, Kubernetes resources created by the operator Helm chart, Kubernetes resources created by the operator, and the operator REST interface. We intend to maintain compatibility for three releases, except in the case of a clearly communicated deprecated feature, which will be maintained for one release after a replacement is available.
