Running Oracle WebLogic on containers

Abstract

CERN IT department is providing production services to run containers. Given that, the IT-DB team, responsible to run the Java based platforms, has started a new project to move the WebLogic deployments from virtual or bare metal servers to containers: Docker on Kubernetes allow to improve the overall productivity of the team by reducing both operations time and time-to-delivery. Additionally, this framework allows us deploy our services in a fully-reproducible fashion. The scope of the project goes from the design and production of Docker images, deployment environments based on Kubernetes as well as all procedures and operations including the needed tools to hand over to users the management of their deployed applications. This article illustrates how at CERN we have faced all the technical and design aspects to run it in a production environment. That means the implementation of the solutions needed including monitoring, logging, high availability, security and traceability.
