#OOW2015      ”...  Docker?”    

#0 ... some basics

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 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

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

dockerize it!

You can pass environment variables for specific settings e.g. in prod

#1 the registry

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  

what should be your biggest nightmare: unknown and unofficial images (>14000)

Docker  Registry  

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

#2 clouds

Docker in the Cloud?

Supported by every major cloud provider:

On premise -> all clouds

Docker    Registry  

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  

The new PaaS?

PaaS is more than just code-push...

-> Don’t forget DB as a Service, Integration Service (Oracle ICS) etc.

WebLogic in a Docker Container!

What is supported?

munz & more #29  

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

Docker Whitepaper

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  

Dockerfile

$docker build

Dockerfile and Scripts (from Oracle github)

WebLogic Docker Image (no domain)

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  

Docker Style

•  Independent WLS in container

•  Microservices style architecture

•  Just add your favorite Docker cluster manager

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.)
