Weblogic 12c on docker
- 1. Weblogic 12c on DOCKER By Chandra Rai
- 2. Agenda: Overview of Docker. Docker components and elements. Why Docker and its benefits. Steps to install Docker on RHEL. Steps to install WebLogic 12c using Docker. Demo. ORACLE WEBLOGIC 12c ON DOCKER
- 3. Docker is a platform that enables users to build, package, ship and run applications. Docker users package their applications into a Docker image. Docker images are portable artifacts that can be distributed across Linux environments. OVERVIEW OF DOCKER
- 4. Docker is based on Linux LXC. The main secret sauce behind Docker is Isolation with namespace. Some of the namespaces Docker uses are: Pid, Net, IPC, Mnt, Uts Isolation with Cgroups. For ex: Memory, CPU etc Union File System HOW DOES IT WORK
- 5. Docker Client Docker Daemon Docker Registry Docker Container Docker Images Docker File DOCKER COMPONENTS Source:https://docs.docker.com/engine/a rticle-img/architecture.svg
- 6. Docker containers are lightweight Docker containers are portable. Docker enables devops by breaking the silos between development and operation teams. Enables consistent environments or immutable infrastructure. Hence solving the common problem of mismatch between dev, test and prod envs. BENEFITS OF DOCKER
- 7. Docker is supported on RHEL 7 Minimum kernel version required is 3.10 Docker can be installed using the “yum” package manger. Install the docker package using the command : “sudo yum install docker-engine” Start the docker engine: “sudo service docker start” Check you have a working install: “sudo docker info” DOCKER INSTALLATION
- 8. Weblogic 12c is certified on Docker. Oracle has released dockerfiles and supporting scripts to build Weblogic docker images on GitHub. (https://github.com/oracle/docker- images/tree/master/OracleWebLogic) Using these dockerfiles custom WLS docker image can be built. Pre-requisites are required JDK and WLS binaries should be copied to appropriate location before bootstrapping the image via dockerfile. INSTALL WEBLOGIC 12c USING DOCKER
- 9. The following steps will create a Weblogic docker image using which the containers can be spawned. sudo docker build https://github.com/oracle/docker- images/OracleWeblogic From OracleWeblogic/samples/1213-domain folder run sudo docker build -t oracle/weblogic:12.1.3 . Now its time to boot up the container for Admin server using sudo docker run –d –p 7001:7001 –name wlsadmin oracle/weblogic:12.1.3 Verify at http://ip:7001/console (Ip is public ip of aws instance) INSTALL WEBLOGIC 12c USING DOCKER… Contd..
- 10. This talk gives an overview of Docker and simple application/use of it to dockerize Weblogic. The intent is to spread the Dev-ops philosophy within our company. Maybe in future implement OFMW development labs using Docker. Takeaways…..

Editor's Notes
- #4: Docker images are portable artifacts that can be distributed across Linux environments. Images that have been distributed can be used to instantiate containers where applications can run in isolation from other applications running in other containers on the same host operating system.
