This document discusses Oracle WebLogic Server 12c running with Docker containers. It begins with introductions of Bruno Borges from Oracle and Dr. Frank Munz. It then provides an overview of Docker and how it differs from virtualization. Docker images and containers are explained. Using Docker with clouds is discussed. Finally, running WebLogic Server within a Docker container is covered, including what is supported and example Dockerfiles and scripts.

”...
Docker?”

9. #0
... some basics

10. Docker
• Open Source (evolving), written in Go
• Container technology supported by Oracle
• Portable Standard
• Runs on Linux (and Microsoft, Solaris)
Google starts
2.000.000.000
containers
per week!

Docker is not a

Containers run on

-> Containers are

13. Docker Images
• Package format
• Layered incremental file system
• “Application with all dependencies”
• Create it yourself
or get it from Docker Hub
$
docker
images
munz & more #13
Example Layers:
- WLS Domain
- WebLogic
- Java
- Base Image

14. Docker Container
• Isolated runtime of image
• Start up in milliseconds
• Sandboxing uses Linux namespaces and cgroups
-> isolated part of your Linux
• Open Container Standard / Linux Foundation

ProducVon
dockerize it!
You can pass environment
variables for specific
settings e.g. in prod

16. #1
the registry

17. Registry
• Hosted, code open sourced
• Docker image is not found? pulled from registry
• Push your image to registry
$docker
push
yourname/newimage
• Free account includes 1 private registry
• Also private, containerized registry for download
with fs and optional in-memory S3, or Azure data
store
munz & more #17

18. what should be your
biggest nightmare:
unknown and
unofficial images
(>14000)
Docker
Registry

19. Automated Builds
• Automatically build your images:
GitHub account with Dockerfile
• Registry uses GitHub directory structure
as build context
• Image is uploaded automatically
to Docker hub
-> Trust, up to date, and transparent

20. #2
clouds

21. Docker in the Cloud?
Supported by every major cloud provider:
munz & more #21
On premise -> all clouds
Docker
Registry

22. The new PaaS?
”PaaS: some hosted platform* that runs
my Java, Java EE, node.js, or Ruby code.”
Now you build your all-incl. container yourself...
->PaaS: platform that runs containers?
*real cloud: API, elasticity, and pay per use
munz & more #22

23. The new PaaS?
PaaS is more than just code-push...
-> Don’t forget DB as a Service, Integration Service
(Oracle ICS) etc.

Check the ff.
Oracle docs:
- CertMatrix
- WLS &

Whitepaper

30. What Do You Get?
• NOT WebLogic from Docker registry
• NO automatic build via github
• Github repo with scripts
to set up WebLogic on
Oracle Linux in Docker
• Dev or generic distribution
• Docker is a supported
environment for
WebLogic 12.1.3
munz & more #30

31. Dockerfile
$docker build
Dockerfile and Scripts
(from Oracle github)
WebLogic

(no domain)

32. Extend the WLS-only image
Sample script provided:
• Dockerfile to extend WLS image. Starts with
FROM
oracle/weblogic:12.1.3-­‐dev
• Run WLST script to create domain
• Create boot.properties
• Expose NM, Server ports
• Default command: startWebLogic.sh
munz & more #32

33. Docker Style
• Independent WLS in container
• Microservices style architecture
• Just add your favorite Docker
cluster
manager

36. Facts to Know
• Oracle supports WebLogic on Docker
• Docker networking is still experimental
-> limitations for cross-machine deployments
• Docker cluster managers are still evolving
(Kubernetes, Apache Mesos with Marathon, AWS ECS,
CloudFoundry, etc.)
