Running WebLogic on Docker

Introduction

This lab will showcase the use of the Oracle provided WebLogic Docker image to spin up an instance of a WebLogic server on a local machine. Via the WebLogic management console you will install a demo app, and validate it is working correctly via a browser.

Prerequisites

To run this lab, you need following elements :

• An Oracle account to download the docker image. To create an account, follow instructions here
• docker software installed on your machine
  • If you are following this lab as part of an Oracle physical event, your instructor might provide you with a Linux Virtual machine, in which case you can simply access the desktop of that environment via a VNC viewer. Docker will already be running on that environment.
  • Install instructions for docker can be found here

Downloading the WebLogic Docker image:

• Navigate to the Oracle Container Registry

• https://container-registry.oracle.com/

• Choose Middleware, and then WebLogic

• You need to sign into the Oracle website to accept the License agreement.

  • Click on Sign In
  • Accept the T&C

  

• Start the docker software on your machine

  • On a laptop, launch the Docker Desktop application
  • Users of a Linux Virtual machine : docker will already be running

• Open a new console window, and perform following operations:

  • Login to the oracle docker registry with your Oracle credentials (username / password)

    docker login container-registry.oracle.com
    

  • Now pull down the image :

    docker pull store/oracle/weblogic:12.2.1.3-dev-190111
    

• After the download has finished, you can do following command to validate the image is available:

  docker images
  
  REPOSITORY                                          TAG                   IMAGE ID            CREATED             SIZE
  container-registry.oracle.com/middleware/weblogic   12.2.1.3-dev-190111   7cbc48edced8        6 months ago        970MB
  
  

Starting up a WebLogic container

• Create a local file called domain.properties with following content :

username=weblogic
password=welcome1

• Run the container :

docker run -d -p 7001:7001 -p 9002:9002 \
  -v $PWD:/u01/oracle/properties container-registry.oracle.com/middleware/weblogic:12.2.1.3-dev-190111

• Validate the WLS domain is running by connecting to the admin console :

  https://localhost:9002/console/

  • You will have to ackowledge a security exception
  • Wait for the admin console to start, and log in with the username / password you specified in the domain.properties file.

  You should now be on the WebLogic Admin console

Run a Sample application

Now let's deploy a very simple sample app.

• Download the war file from this location

  • : https://github.com/AKSarav/SampleWebApp/raw/master/dist/SampleWebApp.war. See this link for more info on this application.

• In the WLS console, navigate to "Deployments"

  

• Click "Install"

  

  • Use the "Upload your file" link in the "Note" text to upload the war file you downloaded before

    

  • Hit Next, choose the default 'Install as application" option, then Finish

  • Check parameters in the "Testing" tab, you should see your app deployed on 7001/SampleWebApp

• Now access the app in your browser : http://localhost:7001/SampleWebApp/
